CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE SECOND CIRCUIT
The Warsaw Convention (Convention), an international air carriage treaty that the United States ratified in 1934, sets a limit on an air carrier's liability for lost cargo at 250 gold French francs per kilogram, which sum may be converted into any national currency. In 1978, Congress repealed the Par Value Modification Act (PVMA), which set an "official" price of gold in the United States. Nevertheless, the Civil Aeronautics Board (CAB) continued to sanction the use of the last official price of gold as a conversion factor. As a result, a $9.07-per-pound limit of liability remained codified in the CAB regulations governing international air carriers' tariffs filed under the Federal Aviation Act of 1958. Franklin Mint Corp. brought suit in Federal District Court against Trans World Airlines (TWA) to recover damages in the amount of $250,000 for the loss in 1979 of packages containing numismatic materials delivered to TWA for transport from Philadelphia to London. The parties having stipulated that TWA was responsible for the loss, the only dispute was the extent of liability. The District Court ruled that, under the Convention, the liability was limited to $6,475.98, a figure derived from the weight of the packages, the Convention's liability limit, and the last official price of gold in the United States. The Court of Appeals affirmed, but also ruled that, 60 days from the issuance of the mandate, the Convention's liability limit would be unenforceable in the United States, since enforcement of the Convention required a factor for converting the liability limit into dollars, and there was no United States legislation specifying a factor to be used by United States courts.
1. The Convention's cargo liability limit remains enforceable in United States courts, and was not rendered unenforceable by the 1978 repeal of the PVMA. Pp. 466 U. S. 251-253.
(a) Legislative silence is not sufficient to abrogate a treaty. Here, neither the legislative histories of the various PVMA's, the history of the repealing Act, nor the repealing Act itself, make any reference to the
Convention, the repeal being unrelated to the Convention and intended to give formal effect to a new international monetary system. Since the Convention is a self-executing treaty, no domestic legislation is required to give it the force of law in the United States. And neither Congress nor the Executive Branch has given the required notice to other parties to the Convention that the United States planned to abrogate the Convention. To the contrary, the Executive Branch continues to maintain that the Convention's liability limit remains enforceable in the United States. Pp. 466 U. S. 251-253.
(b) When the parties to a treaty continue to assert its vitality, a private person may not invoke the doctrine of rebus sic stantibus to assert that a treaty ceases to be binding when there has been a substantial change in conditions since its promulgation. Accordingly, the erosion of the international gold standard and the 1978 repeal of the PVMA cannot be construed as terminating or repudiating the United States' duty to abide by the Convention's liability limit. P. 466 U. S. 253.
2. A $9.07-per-pound liability limit is not inconsistent with domestic law or with the Convention itself. Pp. 466 U. S. 254-260.
(a) It is clear that such limit does not contravene any domestic legislation, absent any suggestion by Congress when it repealed the PVMA that the CAB should thereafter use a conversion factor different from the official price of gold or that either of the political branches expected or intended the repealing Act to affect the dollar equivalent of the Convention's liability limit. P. 466 U. S. 255.
(b) Tying the Convention's liability limit to today's gold market would fail to effect any purpose of the Convention's framers, and would be inconsistent with well-established international practice. A fixed $9.07-per-pound liability limit represents a choice not inconsistent with the Convention's purposes of setting some limits on a carrier's liability, of setting a stable, predictable, and internationally uniform limit that would encourage the growth of the air carrier industry, and of linking the Convention to a constant value that would keep step with the average value of cargo carried, and so remain equitable for carriers and transport users alike. Pp. 466 U. S. 255-260.
690 F.2d 303, affirmed.
O'CONNOR, J., delivered the opinion of the Court, in which BURGER, C.J., and BRENNAN, WHITE, MARSHALL, BLACKMUN, POWELL, and REHNQUIST JJ., joined. STEVENS, J., filed a dissenting opinion, post, p. 466 U. S. 261.
JUSTICE O'CONNOR delivered the opinion of the Court.
The question presented in this litigation is whether an air carrier's declared liability limit of $9.07 per pound of cargo is inconsistent with the "Warsaw Convention" [Footnote 1] (Convention), an international air carriage treaty that the United States has ratified. As a threshold matter we must determine whether the 1978 repeal of legislation setting an "official" price of gold in the United States renders the Convention's gold-based liability limit unenforceable in this country. We conclude that the 1978 legislation was not intended to affect the enforceability of the Convention in the United States, and that a $9.07-per-pound liability limit is not inconsistent with the Convention.
In 1974, the Civil Aeronautics Board (CAB) informed international air carriers doing business in the United States that the minimum acceptable carrier liability limit for lost cargo would thenceforth be $9.07 per pound. Trans World Airlines, Inc. (TWA), has complied with the CAB order since that time. On March 23, 1979, Franklin Mint Corp. (Franklin
Mint) delivered four packages of numismatic materials with a total weight of 714 pounds to TWA for transportation from Philadelphia to London. Franklin Mint made no special declaration of value at the time of delivery. [Footnote 2] The packages were subsequently lost. Franklin Mint brought suit in United States District Court to recover damages in the amount of $250,000. The parties stipulated that TWA was responsible for the loss of the packages. The only dispute concerns the extent of TWA's liability.
The District Court ruled that, under the Convention, TWA's liability was limited to $6,475.98, a figure derived from the weight of the packages, the liability limit set out in the Convention, and the last official price of gold in the United States. The Court of Appeals for the Second Circuit affirmed the judgment, but "rul[ed]" that, 60 days from the issuance of the mandate, the Convention's liability limit would be unenforceable in the United States. 690 F.2d 303 (1982).
In a petition for certiorari to this Court, TWA challenged the Court of Appeals' declaration that the Convention's liability limit is prospectively unenforceable. In a cross-petition, Franklin Mint contended that the Court of Appeals' actual holding should have been retrospective as well. We granted both petitions, 462 U.S. 1118 (1983). We now conclude that the Convention's cargo liability limit remains enforceable in United States courts and that the CAB-sanctioned $9.07-per-pound liability limit is not inconsistent with the Convention. Accordingly, we affirm the judgment of the Court of Appeals, but reject its declaration that the Convention is prospectively unenforceable.
The Convention was drafted at international conferences in Paris in 1925, and in Warsaw in 1929. The United States
became a signatory in 1934. More than 120 nations now adhere to it. The Convention creates internationally uniform rules governing the air carriage of passengers, baggage, and cargo. Under Article 18, carriers are presumptively liable for the loss of cargo. Article 22 sets a limit on carrier liability:
"(2) In the transportation of checked baggage and of goods, the liability of the carrier shall be limited to a sum of 250 francs per kilogram, unless the consignor has made, at the time when the package was handed over to the carrier, a special declaration of the value at delivery and has paid a supplementary sum if the case so requires. . . ."
"* * * *"
"(4) The sums mentioned above shall be deemed to refer to the French franc consisting of 65 1/2 milligrams of gold at the standard of fineness of nine hundred thousandths. These sums may be converted into any national currency in round figures."
Reprinted (in English translation) in note following 49 U.S.C. § 1502.
In the United States, the task of converting the Convention's liability limit into "any national currency" falls within rulemaking authority which was, for many years, including those at issue here, delegated to the CAB under the Federal Aviation Act of 1958 (FAA), 49 U.S.C. § 1301 et seq. [Footnote 3] International air carriers are required to file tariffs with the CAB specifying "in terms of lawful money of the United States" the rates and conditions of their services, including the cargo liability limit that they claim. [Footnote 4] The Act forbids any carrier to charge a
"greater or less or different compensation
for air transportation, or for any service in connection therewith, than the rates, fares, and charges specified in then currently effective tariffs. . . . [Footnote 5]"
The CAB, for its part, is empowered to reject any tariff that is inconsistent with the FAA or CAB regulations. 49 U.S.C. § 1373(a). CAB powers are to be exercised
"consistently with any obligation assumed by the United States in any treaty, convention, or agreement that may be in force between the United States and any foreign country or foreign countries. . . ."
49 U.S.C. § 1502.
During the first 44 years of the United States' adherence to the Convention, there existed an "official" price of gold in the United States, and the CAB's task of supervising carrier compliance with the Convention's liability limit was correspondingly simple. The United States Gold Standard Act of 1900 set the value of the dollar at $20.67 per troy ounce of gold. [Footnote 6] On January 31, 1934, nine months before the United States ratified the Convention, President Roosevelt increased the official domestic price of gold to $35 per ounce. [Footnote 7] In 1945, the United States accepted membership in the International Monetary Fund (IMF), and so undertook to maintain a "par value" for the dollar and to buy and sell gold at the official price in exchange for balances of dollars officially held by other IMF nations. [Footnote 8] For almost 40 years, the $35-per-ounce price of gold was used to derive from the Convention's
Article 22(2) a cargo liability limit of $7.50 per pound. See, e.g., 14 CFR § 221.176 (1972).
When the central banks of most Western nations instituted a "two-tier" gold standard in 1968, the gold-based international monetary system began to collapse. Thereafter, official gold transactions were conducted at the official price, and private transactions at the floating, free market price. App. 21. In August, 1971, the United States suspended convertibility of foreign official holdings of dollars into gold. In December, 1971, and then again in February, 1973, the official exchange rate of the dollar against gold was increased. These changes were approved by Congress in the Par Value Modification Act, passed in early 1972 (increasing the official price to $38 per ounce [Footnote 9]) and in its 1973 reenactment (setting a $42.22-per-ounce price [Footnote 10]). Each time, the CAB followed suit by directing carriers to increase the dollar-based liability limits in their tariffs accordingly, first to $8.16 per pound, [Footnote 11] then to $9.07 per pound. [Footnote 12]
In 1975, the member nations of the IMF formulated a plan, known as the Jamaica Accords, to eliminate gold as the basis of the international monetary system. [Footnote 13] Effective April 1, 1978, the "Special Drawing Right" (SDR) was to become the sole reserve asset that IMF nations would use in their mutual dealings. The SDR was defined as the average value of a defined basket of IMF member currencies. [Footnote 14] In 1976 Congress
passed legislation to implement the new IMF agreement, [Footnote 15] repealing the Par Value Modification Act effective April 1, 1978.
As these developments unfolded, the Convention signatories met in Montreal in September, 1975. In No. 4 of the "Montreal Protocols," [Footnote 16] the delegates proposed to substitute 17 SDR's per kilogram for the 250 French gold francs per kilogram in Article 22 of the Convention. Although the United States supported this change, and signed Protocol No. 4, [Footnote 17] the Senate has not yet consented to its ratification. [Footnote 18]
The erosion and final demise of the gold standard, coupled with the United States' failure to ratify Montreal Protocol No. 4, left the CAB with the difficult task of supervising carrier compliance with the Convention's liability limits without up-to-date guidance from Congress. Although the market price of gold began to diverge from the official price in 1969, the CAB continued to track the official price in Orders converting the Convention's liability limit into dollars. Under CAB Order 74-1-16, promulgated in 1974,
"the minimum acceptable figur[e] in United States dollars for liability limits
applicable to 'international transportation' and 'international carriage' . . . [is $] 9.07 [per pound of cargo]. [Footnote 19]"
Since 1978, the CAB has actively reviewed this $9.07-per-pound liability limit. [Footnote 20] As of 1979, however, the CAB continued to sanction the use of the last official price of gold -- $42.22 per ounce -- as a conversion factor. A CAB Order published on August 14, 1978, restated the CAB's position. [Footnote 21] The $9.07-per-pound limit remained codified in CAB regulations, see 14 CFR § 221.176 (1979), and CAB Order 74-1-16 was still in force. TWA, like other international carriers, remained subject to Order 74-1-16.
The most important issue raised by the parties is whether the 1978 repeal of the Par Value Modification Act rendered the Convention's cargo liability limit unenforceable in the United States. The Court of Appeals so declared, reasoning that (i) enforcement of the Convention requires a factor for converting the liability limit into dollars and (ii) there is no United States legislation specifying a factor to be used by United States courts. We do not accept this analysis.
There is, first, a firm and obviously sound canon of construction against finding implicit repeal of a treaty in ambiguous congressional action.
"A treaty will not be deemed to have been abrogated or modified by a later statute unless such purpose on the part of Congress has been clearly expressed."
Cook v. United States, 288 U. S. 102, 288 U. S. 120 (1933). See also Washington v. Washington Commercial Passenger Fishing Vessel Assn., 443 U. S. 658, 443 U. S. 690 (1979); Menominee Tribe of Indians v. United States, 391 U. S. 404, 391 U. S. 412-413 (1968); Pigeon River Improvement, Slide & Boom Co. v. Charles W. Co, Ltd., 291 U. S. 138, 291 U. S. 160 (1934). Legislative silence is not sufficient to abrogate a treaty. Weinberger v. Rossi, 456 U. S. 25, 456 U. S. 32 (1982). Neither the legislative histories of the Par Value Modification Acts, the history of the repealing Act, nor the repealing Act itself, make any reference to the Convention. The repeal was unrelated to the Convention; it was intended to give formal effect to a new international monetary system that had, in fact, evolved almost a decade earlier.
Second, the Convention is a self-executing treaty. Though the Convention permits individual signatories to convert liability limits into national currencies by legislation or otherwise, no domestic legislation is required to give the Convention the force of law in the United States. The repeal of a purely domestic piece of legislation should accordingly not be read as an implicit abrogation of any part of it. See generally Bacardi Corp. of America v. Domenech, 311 U. S. 150, 311 U. S. 161-163 (1940).
Third, Article 39 of the Convention requires a signatory that wishes to withdraw from the Convention to provide other signatories with six months' notice, formally communicated through the Government of Poland. [Footnote 22] The repeal of the
Par Value Modification Act had a sufficient lead time, but Congress and the Executive Branch took no steps to notify other signatories that the United States planned to abrogate the Convention. To the contrary, the Executive Branch continues to maintain that the Convention's liability limit remains enforceable in the United States. Brief for United States as Amicus Curiae. In these circumstances, we are unwilling to impute to the political branches an intent to abrogate a treaty without following appropriate procedures set out in the Convention itself. See The Federalist No. 64, pp. 436-437 (J. Cooke ed.1961) (J. Jay).
Franklin Mint suggests that a treaty ceases to be binding when there has been a substantial change in conditions since its promulgation. [Footnote 23] A treaty is in the nature of a contract between nations. The doctrine of rebus sic stantibus does recognize that a nation that is party to a treaty might conceivably invoke changed circumstances as an excuse for terminating its obligations under the treaty. [Footnote 24] But when the parties to a treaty continue to assert its vitality, a private person who finds the continued existence of the treaty inconvenient may not invoke the doctrine on their behalf.
For these reasons, the erosion of the international gold standard and the 1978 repeal of the Par Value Modification Act cannot be construed as terminating or repudiating the United States' duty to abide by the Convention's cargo liability limit. We conclude that the limit remains enforceable in United States courts.
The Court of Appeals correctly recognized that the Convention's liability limit must be converted into dollars. This requirement derives not from the Convention itself -- the Convention merely permits such a conversion -- but from the tariff requirements of § 403(a) of the FAA. [Footnote 25] 49 U.S.C. § 1373(a).
In 1979, when Franklin Mint's cargo was lost, TWA's tariffs set the carrier's cargo liability limit at $9.07 per pound. This tariff had been filed with and accepted by the CAB pursuant to § 403(a), and was squarely consistent with CAB Order 74-1-16. The $9.07-per-pound limit thus represented an Executive Branch determination, made pursuant to properly delegated authority, of the appropriate rate for converting the Convention's liability limits into United States dollars. We are bound to uphold that determination unless we find it to be contrary to law established by domestic legislation or by the Convention itself. [Footnote 26]
It is clear, first, that the CAB's choice of a cargo liability limit of $9.07 per pound does not contravene any domestic legislation. When an official price of gold was set by statute, the CAB did, of course, use that price to translate the Convention's gold-based liability limit into dollars. But when Congress repealed the Par Value Modification Act, it did not suggest that the CAB should thereafter use a different conversion factor. Indeed, there is no hint that either of the political branches expected or intended that Act to affect the dollar equivalent of the Convention's liability limit.
Whether the CAB's choice of a $9.07-per-pound limit is compatible with the Convention itself is more debatable. The Convention included liability limits, and expressed them in terms of gold, to effect several different, and to some extent contradictory, purposes. Our task of construing those purposes is, however, made considerably easier by the 50 years of consistent international and domestic practices under the Convention. For the reasons stated below, we conclude that tying the Convention's liability limit to today's gold market would fail to effect any purpose of the Convention's framers, and would be inconsistent with well-established international
practice, acquiesced in by the Convention's signatories over the past 50 years. A fixed $9.07-per-pound liability limit therefore represents a choice by the CAB sufficiently consistent with the Convention's purposes.
The Convention's first and most obvious purpose was to set some limit on a carrier's liability for lost cargo. Any conversion factor will have this effect; in this regard, a $9.07-per-pound liability limit is as reasonable as one based on SDR's or the free market price of gold.
The Convention's second objective was to set a stable, predictable, and internationally uniform limit that would encourage the growth of a fledgling industry. To this end the Convention's framers chose an international, not a parochial, standard, free from the control of any one country. [Footnote 27] The CAB's choice of a $9.07-per-pound liability limit is certainly a stable and predictable one on which carriers can rely. We recognize, however that, in the long term, effectuation of the Convention's objective of international uniformity might require periodic adjustment by the CAB of the dollar-based limit to account both for the dollar's changing value relative to other Western currencies and, if necessary, for changes in the conversion rates adopted by other Convention signatories. Since 1978, however, no substantial changes of either type have occurred.
Despite the demise of the gold standard, the $9.07-per-pound liability limit retained since 1978 has represented a reasonably stable figure when converted into other Western currencies This is easily established by reference to the SDR, which is the new, nonparochial, internationally recognized standard of conversion. On March 31, 1978, for example,
one SDR was worth $1.23667; on March 23, 1979, $1.28626. [Footnote 28] At all times since 1978, a carrier that chose to set its liability limit at 17 SDR's per kilogram as suggested by Montreal Protocol No. 4 would have arrived at a liability limit in dollars close to $9 per pound. [Footnote 29]
The CAB's $9.07-per-pound liability limit also appears to have been a reasonable interim choice for keeping the Convention's liability limit as enforced in the United States in line with limits enforced by other signatories. As of December 31, 1975, 15 nations [Footnote 30] had signed Montreal Protocol No. 4, suggesting their intent to set a liability limit of 17 SDR's per kilogram; other nations have chosen to continue using the last official price of gold for converting the Convention's cargo liability limit into national currencies. [Footnote 31] Insofar as has been
possible in the unsettled circumstances since 1975, the CAB's choice of a $9.07-per-pound limit has thus furthered the Convention's intent to set an internationally uniform liability limit.
We recognize that this inquiry into the dollar's value relative to other currencies would have been unnecessary if the CAB had chosen to adopt the market price of gold for converting the Convention's liability limits into dollars. Since gold is freely traded on an international market, its price always provides a unique and internationally uniform conversion rate. But reliance on the gold market would entirely fail to provide a stable unit of conversion on which carriers could rely. To pick one extreme example, between January and April, 1980, gold ranged from about $490 to $850 per ounce. App. 24. Far from providing predictability and stability, tying the Convention to the gold market would force every carrier and every air transport user to become a speculator in gold, exposed to the sudden and unpredictable swings in the price of that commodity. The CAB has correctly recognized that this is not at all what the Convention's framers had in mind. The 1978 decision by many of the Convention's signatories to exit from the gold market cannot sensibly be construed as a decision to compel every air carrier and air transport user to enter it.
A third purpose of the Convention's gold-based limit may have been to link the Convention to a constant value that
would keep step with the average value of cargo carried, and so remain equitable for carriers and transport users alike. [Footnote 32] We recognize that, in an inflationary economy, a fixed, dollar-based liability limit may fail in the long-term to achieve that purpose. Nonetheless, for the reasons that follow, we cannot fault the CAB's decision to adhere, in the six years since 1978, to a constant $9.07-per-pound liability limit.
The Convention's framers viewed the treaty as one "drawn for a few years," not for "one or two centuries." [Footnote 33] That it has, in fact, been adhered to for over half a century is a tribute not only to the framers' skills but to the signatories' manifest willingness to accept a flexible implementation of the Convention's terms. The indisputable fact is that, between 1934 and 1978, the signatories, by common if unwritten consent, allowed the value of the liability limit as measured by the free market price of both gold and other commodities to decline substantially, even while the official price of gold was formally maintained. [Footnote 34] We may not ignore the actual, reasonably harmonious practice adopted by the United States and other signatories in the first 40 years of the Convention's existence. See Factor v. Laubenheimer, 290 U. S. 276, 290 U. S. 294-295 (1933); Day v. Trans World Airlines, Inc., 528 F.2d 31, 35-36 (CA2 1975), cert. denied, 429 U.S. 890 (1976); Restatement (Second) of Foreign Relations Law of the United States § 147(1)(f) (1965); 2 C. Hyde, International Law 72 (1922). In determining whether the Executive Branch's domestic implementation of the Convention is consistent with
the Convention's terms, our task is to construe a "contract" among nations. The conduct of the contracting parties in implementing that contract in the first 50 years of its operation cannot be ignored.
As of March 31, 1978, $9.07 per pound of cargo therefore represented a "correct" conversion of the Convention's liability limit into dollars. [Footnote 35] Though the purchasing power of the dollar has declined somewhat since then, the $9.07-per-pound liability limit, viewed in light of international practice, cannot be declared inconsistent with the purposes of the Convention and the shared understanding of its signatories.
Moreover, tying the Convention's liability limit to the free market price of gold would no longer serve to maintain a constant value of carriers' liability. Since 1978, gold has been only "a volatile commodity, not related to a price index, or to the rate of inflation, or indeed to any meaningful economic measure. . . ." [Footnote 36] A liability limit tied to the gold market might be convenient for a dispatcher of gold bullion, but such a limit would simply force other air transport users and carriers to become unwilling speculators in the gold market. Whatever other purposes they may have had, the Convention's framers and signatories did not intend to adopt or agree to a liability limit that is fluid, uncertain, and altogether inconvenient. [Footnote 37] The Convention was intended to reduce, not to increase, the economic uncertainties of air transportation.
The political branches, which hold the authority to repudiate the Warsaw Convention, have given no indication that
they wish to do so. Accordingly, the Convention's cargo liability limit remains enforceable in the United States.
Article 22(4) of the Convention permits conversion of the liability limit into "any national currency." In the United States, the authority to make that conversion has been delegated by Congress to the Executive Branch. The courts are bound to respect that arrangement unless the properly delegated authority is exercised in a manner inconsistent with domestic or international law. We conclude that the CAB's decision to continue using a $42.22 per ounce of gold conversion rate after the repeal of the Par Value Modification Act was consistent with domestic law and with the Convention itself, construed in light of its purposes, the understanding of its signatories, and its international implementation since 1929.
We reject the Court of Appeals' declaration that the Convention is prospectively unenforceable; the judgment of the Court of Appeals affirming the judgment of the District Court is

But on March 8, 1983, by a vote of 50 to 42 in favor of ratification, the Senate failed to reach the two-thirds majority required for consent. The matter remains on the Senate calendar. See S.Exec.Rep. No. 97-45 (1981); 129 Cong.Rec. S2270, S2279 (daily ed. Mar. 8, 1983); S.Exec.Rep. No. 98-1 (1983).

Note following 49 U.S.C. § 1502. The United States has, in fact, followed this procedure once before. On November 15, 1965, the United States delivered a formal notice of denunciation of the Convention to the Polish Peoples Republic. See Lowenfeld & Mendelsohn, The United States and the Warsaw Convention, 80 Harv.L.Rev. 497, 546-552 (1967). The notice was later withdrawn.
See Restatement (Second) of Foreign Relations Law of the United States § 153, and Comment c (1965).
However, Article 39(2) of the Convention expressly permits a Convention signatory to withdraw by giving timely notice. Plainly, a party to a treaty of voluntary adhesion can have no need for the doctrine of rebus sic stantibus except insofar as it might wish to avoid the notice requirement.
In this connection the Court of Appeals stated:
"[In repealing the Par Value Modification Act] Congress thus abandoned the unit of conversion specified by the Convention and did not substitute a new one. Substitution of a new term is a political question, unfit for judicial resolution. We hold, therefore, that the Convention's limits on liability for loss of cargo are unenforceable in United States Courts."
690 F.2d 303, 311 (CA2 1982) (footnote omitted).
In our view, Congress has not abandoned any "unit of conversion specified by the Convention" -- the Convention specifies liability limits in terms of gold francs, and provides no unit of conversion whatsoever. To the contrary, the Convention invites signatories to make the conversion into national currencies for themselves. In the United States, the CAB has been delegated the power to make the conversion, and has exercised the power most recently in Order 74-1-16. We are not called upon to "[s]ubstitut[e] a new term," but merely to determine whether the CAB's Order is inconsistent with the Convention. That determination does not engage the "political question" doctrine.
The dissent apparently has no difficulty accepting that, while Congress selected the conversion rate between gold and the dollar, "[o]ur practice was consistent with the Convention," see post at 466 U. S. 277, n. 6, even though the conversion rate selected bore no relation whatsoever to the dollar price of gold on the free market, see nn. 35 37 infra. The dissent does not explain why the CAB, whose powers are exercised pursuant to express congressional delegation, was disqualified from setting a similar conversion rate one year after Congress stopped doing so.
Article 22(4) of the Convention expressly permits each signatory nation to convert the Convention's liability limits into any national currency, but provides no conversion rates for doing so. In this country, 49 U.S.C. § 1373(a) requires such a conversion into dollars. The CAB has been delegated authority under which it may determine the appropriate conversion rate, and it has exercised that authority. Thus, for the extremely narrow purpose of converting the Convention's liability limits into dollars, Congress has indeed "delegated its authority over the currency to the CAB." See post at 466 U. S. 278, n. 6. We may overrule the CAB's action only if we conclude that it is inconsistent with the purposes of the Convention or with domestic law.

The CAB has in fact accepted airline tariffs in which liability limits are based on SDR's instead of the fixed $9.07 figure.

In other countries, the courts have taken the initiative in adopting the SDR as the new unit of conversion. See, e.g., Kislinger v. Austrian Airtransport, No. l R 145/83 (Commercial Court of Appeals of Vienna Austria, June 21, 1983) (English translation in App. to Brief for Petitioner TWA at BA12); Rendezvous-Boutique-Pafumerie Friedrich und Albine Breitinger GmbH v. Austrian Airlines, No. 14 R 11/83 (Court of Appeals of Linz, Austria, June 17, 1983) (English translation in App. to Brief for Petitioner TWA at BA22).
At least one court has relied instead on the last official price of gold. See Costell v. Iberia, Lineas Aereas de Espana, S. A., No. 255 (Court of Appeal of Valencia, Spain, Oct. 16, 1981) (English translation in App. to Brief for Petitioner TWA at BA6).

Excerpt From Warsaw Convention Conference Minutes, October 4-12, 1929, reprinted at App. 162 (remark of Mr. Rippert (France)).
For a hypothetical 44-pound lost suitcase, the liability limit was $330 in 1934, $359 in 1972, and $400 in 1974. In terms of purchasing power, $330 in 1934 were equivalent to $1,031 in 1972 and $1,215 in 1974. Id. at 48. Clearly, the $9.07-per-pound liability limit does not represent the same value that was in effect when the United States adhered to the Convention.
On that date, the official price of gold remained at $42.22 per ounce; the free market price of gold was about $182 per ounce. See The Wall Street Journal, Apr. 3, 1978, p. 29, col. 1.
Lowenfeld, supra, n 17, § 6.51, at 7-169.
It is noteworthy that, in the decade between 1968 and 1978, the free market price of gold rose as high as $200 per ounce, App. 24, yet the $42.22 official price of gold was uniformly accepted during that period as appropriate for converting the Convention's liability limit into dollars.
JUSTICE STEVENS, dissenting.
This litigation involves the interpretation of Article 22 of the Warsaw Convention. The plain language of that Article, quoted ante at 466 U. S. 247, requires that the liability limits be determined by reference to the value of "gold at the standard of fineness of nine hundred thousandths" and then converted into our "national currency in round figures."
The Court states that the Warsaw Convention's liability limitation remains enforceable in United States courts, but that is not what the Court holds. The Court holds that the liability limitation agreed upon by the Convention is not enforceable in United States courts. Rather, a liability limitation set by Trans World Airlines, and accepted by the Civil Aeronautics Board, is held to be enforceable in United States courts, because that limitation is deemed to correspond more closely to the Convention's "purposes" than the limitation
actually selected by the Convention itself. Thus, instead of enforcing the Convention's liability limitation, the Court has rewritten it.
A treaty is essentially a contract between or among sovereign nations. See Washington v. Washington Commercial Passenger Fishing Vessel Assn., 443 U. S. 658, 443 U. S. 675 (1979). General rules of construction apply to international agreements. See Ware v. Hylton, 3 Dall.199, 3 U. S. 240-241 (1796) (opinion of Chase, J.). As with any written document, there
"is a strong presumption that the literal meaning is the true one, especially as against a construction that is not interpretation, but perversion. . . ."
"other contracts, . . . are to be read in the light of the conditions and circumstances existing at the time they were entered into, with a view to effecting the objects and purposes of the States thereby contracting,"
Rocca v. Thompson, 223 U. S. 317, 223 U. S. 331-332 (1912); see also Factor v. Laubenheimer, 290 U. S. 276, 290 U. S. 295 (1933), and should be interpreted according to the "received acceptation of the terms in which they are expressed." United States v. D'Auterive, 10 How. 609, 51 U. S. 623 (1851).
The great object of an international agreement is to define the common ground between sovereign nations. Given the gulfs of language, culture, and values that separate nations, it is essential in international agreements for the parties to make explicit their common ground on the most rudimentary of matters. The frame of reference in interpreting treaties is naturally international, and not domestic. Accordingly, the language of the law of nations is always to be consulted in the interpretation of treaties. The Pizarro, 2 Wheat. 227, 15 U. S. 246 (1817). See also Santovincenzo v. Egan, 284 U. S. 30, 284 U. S. 40 (1931) ("As treaties are contracts between independent nations, their words are to be taken in their ordinary meaning as understood in the public law of nations'") (citation omitted));
Society for the Propagation of the Gospel in Foreign Parts v. New Haven, 8 Wheat. 464, 21 U. S. 490 (1823). Constructions of treaties yielding parochial variations in their implementation are anathema to the raison d'etre of treaties, and hence to the rules of construction applicable to them. Geofroy v. Riggs, 133 U. S. 258, 133 U. S. 271 (1890) ("It is a general principle of construction with respect to treaties that they shall be liberally construed so as to carry out the apparent intention of the parties to secure equality and reciprocity between them. As they are contracts between independent nations, in their construction, words are to be taken in their ordinary meaning, as understood in the public law of nations and not in any artificial or special sense impressed upon them by local law, unless such restricted sense is clearly intended"); see also Tucker v. Alexandroff, 183 U. S. 424, 183 U. S. 437 (1902).
Finally, but most fundamentally, a treaty is positive law. Justice Story's words concerning the judicial role in enforcing treaties are strikingly relevant to the issue facing us today:
"In the first place, this Court does not possess any treaty-making power. That power belongs, by the constitution, to another department of the Government; and to alter, amend, or add to any treaty by inserting any clause, whether small or great, important or trivial, would be, on our part, an usurpation of power and not an exercise of judicial functions. It would be to make, and not to construe, a treaty. Neither can this Court supply a casus omissus in a treaty, any more than in a law. We are to find out the intention of the parties by just rules of interpretation applied to the subject matter; and having found that, our duty is to follow it as far as it goes, and to stop where that stops -- whatever may be the imperfections or difficulties which it leaves behind."
"* * * *"
"In the next place, this Court is bound to give effect to the stipulations of the treaty in the manner and to the
extent which the parties have declared, and not otherwise. We are not at liberty to dispense with any of the conditions or requirements of the treaty, or take away any qualification or integral part of any stipulation, upon any notion of equity or general convenience, or substantial justice. The terms which the parties have chosen to fix, the forms which they have prescribed, and the circumstances under which they are to have operation rest in the exclusive discretion of the contracting parties, and, whether they belong to the essence or the modal parts of the treaty, equally give the rule to judicial tribunals. The same powers which have contracted are alone competent to change or dispense with any formality. The doctrine of a performance cy pres, so just and appropriate in the civil concerns of private persons, belongs not to the solemn compacts of nations so far as judicial tribunals are called upon to interpret or enforce them. We can as little dispense with forms as with substance."
Two years after Charles Lindbergh captured the world's imagination by piloting the Spirit of St. Louis from New York to Paris, delegates from two dozen nations met in Warsaw and drafted an international agreement to encourage the establishment of a secure international civil aviation industry. The Warsaw Convention provided a uniform system of documentation for international flights, and, more significantly, a uniform limitation on international carriers' liability to passengers and shippers. International uniformity, naturally, was the touchstone of the Convention. See Preamble of Convention, note following 49 U.S.C. § 1502.
Air transportation was then viewed as dangerous. The liability limitation was deemed necessary in order to enable air carriers "to attract capital that might otherwise be
scared away by the fear of a single catastrophic accident." Lowenfeld & Mendelsohn, The United States and the Warsaw Convention, 80 Harv.L.Rev. 497, 499 (1967). [Footnote 2/1]
In settling on a particular figure for a liability limitation, the delegates at Warsaw first had to agree upon a common standard of value. They did so in unambiguous terms: the standard of value was gold of a stated fineness. Art. 22 (4). The liability limitation for cargo was set at 250 units of fine gold weighing 65 1/2 milligrams per unit. Arts. 22(2), 22(4). [Footnote 2/2] The delegates chose an international standard of value -- a standard which would be the same in Paris as it would be in New York.
The Convention, while using gold as a standard of value, recognized that all nations did not use it as a medium of exchange.
change. Therefore, payment in specie was not required or anticipated by the Convention. Rather, the sum of gold set forth in the Convention could be converted into national currencies in round figures. Art. 22(4). All that making the conversion would entail is knowledge of a fact: the amount of that national currency that would exchange for the specified sum of gold.
The unsuitability of relying upon a national currency as a standard of value was demonstrated as a point of actual fact at the outset of the Convention's deliberations on the liability limitation. The draft proposal prepared prior to the Warsaw proceedings by the Comite International Technique d'Experts Juridique Aeriens -- the functional equivalent of a bill reported to the floor of a legislative assembly by a committee -- suggested a limitation of 100 gold francs. Prior to the Convention, however, the franc had been fluctuating in value. France had suspended the convertibility of its currency into gold since the Great War, but returned to a convertible, devalued franc in 1928. The first order of business at the Warsaw proceedings concerning the liability limitation, therefore, was to convert the liability limits contained in the draft proposal, expressed in gold francs defined by a law of August 5, 1914, to the new stabilized French franc defined by the law of June 25, 1928, to be 65.5 milligrams of fine gold. This was a simple matter, for the standard of value of the two statutes was the same -- gold -- and there was a 1-to-5 ratio between the former gold franc and the new French franc. Since the French currency had stabilized, and since the law of June 25, 1928, defined the French franc in terms of gold, the French proposed that the Convention could eliminate the phrase "the values hereabove are gold values" from the draft proposal. App. 159.
The Swiss delegate submitted a proposal corresponding to the International Railroad Convention for the calculation of values. He stated:
"Naturally, when we prepared our text, the French franc was variable; it has been stabilized since. But the fact that a currency has been stabilized does not imply that it is a final thing; a law can always modify another law. For this reason, in Switzerland, we have preferred to stick to the gold standard, which is the same in all countries, since there is but one quality of gold."
"We would not be opposed to refer to the French franc, but to the gold French franc, that is to say, based on a weight of gold at such and such one thousandth."
"Naturally, one can say 'French franc,' but the French franc, it's your national law which determines it, and one need have only a modification of the national law to overturn the essence of this provision. We must base ourselves on an international value, and we have taken the [gold] dollar. Let one take the gold French franc, it's all the same to me, but let's take a gold value . . . as a basis of calculation, be it American or French."
Id. at 161162 (emphasis supplied).
The French delegate resisted the Swiss proposal, pointing out that the particular formula proposed by the Swiss delegate was based on the definition of the 1914 gold franc, and then stating:
"If this Convention of air law is to be applied during one or two centuries, I would perhaps share the fears of [the Swiss delegate], but it's a question of stabilization which was done in practically every country, for a Convention which is drawn for a few years, and I believe that, when you will have fixed the present French franc, you will add nothing in saying 'gold franc.' What fear can you have? It is evident that the definition will correspond to the present franc."
Id. at 162.
The delegate from Great Britain inquired what would happen if the French franc were to be revalued again. The
French delegate responded that the Convention would apply to the French franc as defined in the 1928 statute. The Swiss delegate then stated no objection to using the French franc, but objected to referring to the French statute, and proposed: "insert in our international convention the same formula as that which you have in France, and we accept it." Id. at 163. The French delegate relented, and the Convention agreed to the proposal.
Once an international standard of value had been agreed to, the remaining order of business was to select the quantitative limitation on liability in units of that standard. A liability limitation of 500 new French francs for cargo was contained in the draft proposal. The French, however, proposed a limit of 100 new French francs per kilogram. The French delegate argued that the draft proposal's limit was too high, based upon air carriers' representations that the 100 franc figure represented the actual value of cargo, on the average. That is, the air carriers divided the declared value of cargo by the number of kilograms of cargo for the year 1928, which yielded a figure of approximately 130 francs per kilogram. Id. at 160. The German delegate argued that the French figure was far too low, and proposed a figure of 250 francs, which was ultimately agreed upon.
A gold clause such as that contained in the Convention was common in treaties, see, e.g., Article 262 of The Treaty of Versailles; Article 214 of The Treaty of St. Germain, and Article 197 of the Treaty of Trianon, and other international agreements. The very year the Convention was drafted, a major controversy on the world financial scene was resolved respecting gold clauses which were not drawn as artfully as that contained in the Convention. The Permanent Court of International Justice, in Payment of Various Serbian Loans Issued in France, 2 Hudson W. C. 340 (1929), and Payment in Gold of Brazilian Federal Loans Issued in France, 2 Hudson W. C. 402 (1929) (Serbian and Brazilian Bond Cases)
(July 12, 1929), held that simple references to the gold franc in certain international obligations were intended to represent a gold standard of value, 2 Hudson W.C., at 365. The court continued:
"As this standard of value was adopted by the Parties, it is not admissible to assert that the standard should not govern the payments because the depreciation in French currency was not foreseen, or, as it is insisted, could not be foreseen at the time the contracts were made. The question is not what the Parties actually foresaw, or could foresee, but what means they selected for their protection. To safeguard the repayment of the loans, they provided for payment in gold value having reference to a recognized standard [of weight and fineness]."
"* * * *"
"The conclusion at which the Court has thus arrived is not affected by the fact that, for more or less extended periods, gold specie in francs or a franc at gold parity was not quoted on the money market, as was the case at the time when the loans were issued; for the value can always be fixed either by comparison with the exchange rates of currency of a country in which gold coin is actually in circulation, or, should this not be possible, by comparison with the price of gold bullion. Once the gold value is fixed, it is its equivalent in money in circulation which constitutes the amount which is payable. . . ."
Id. at 366-367 (emphasis supplied). [To construe the bonds otherwise], in substance, would eliminate the word "gold" from the bonds. The contract of the Parties cannot be treated in such a manner. When the Brazilian Government promised to pay "gold francs," the reference to a well-known standard of value cannot be considered as inserted merely for literary effect, or as a routine expression without significance.
The Court is called upon to construe the promise, not to ignore it.
"* * * *"
". . . It was depreciation in value that was the object of the safeguard, not in this or that particular currency, and it was evidently for this reason that the reference was made to the well-known stability of gold value."
Id. at 422-423 (emphasis supplied).
This language is not only significant in terms of the light that it casts on the law of nations and the delegates' contemporaneous intention, but it is also, quite simply, good law. The dissent argued that the intention of the parties was simply not clear enough from the use of the term gold franc, observing it
"was possible, for instance, to stipulate, and this is frequently done, that the payments must be effected in gold francs of the same weight and standard as that of the franc in circulation at the time in France. . . ."
Id. at 431 (Bustamante, J., dissenting). This, of course, is what the Convention did. Indeed, at the insistence of the Swiss delegate, the Convention went even further, and eliminated the reference to French law altogether. Moreover, the gold clause did not depend on signatory nations' adhering to a gold standard. Indeed, such clauses were used in contemplation of a nation going off the gold standard as a method of describing and measuring payment with the intention of guarding against fluctuations in the value of a domestic currency. Feist v. Societe Intercommunale Belge D'Electricite,  A. C. 161, 171-173.
The intention of the Convention simply could not be more manifest. The plain language of the Convention, the deliberations of the delegates, and the contemporary law of nations leave no question as to the the intent of the gold clause:
"Here what was intended was to assure the payment of a money debt in dollars of a value as constant as that of gold. Norman v. Baltimore & Ohio R. Co., [294 U.S. 240,]
294 U. S. 302 ; cf. Feist v. Societe Intercommunale Belge D'Electricite, L.R.  A.C. 161, 172, 173. . . . Weasel words will not avail to defeat the triumph of intention when once the words are read in the setting of the whole transaction."
Holyoke Water Power Co. v. American Writing Paper Co., 300 U. S. 324, 300 U. S. 336 (1937). The Convention was of the view that its standard of value must have intrinsic value, and that gold, valued throughout the world, was a most suitable measure of value. See 1 A. Smith, The Wealth of Nations 23-28 (1911); J. Mill, Principles of Political Economy 484-485 (1936); See also The Legal Tender Cases, 12 Wall. 457 (1871) (overruling Hepburn v. Griswold, 8 Wall. 603 (1870)); 12 Wall. at 79 U. S. 624 (Clifford, J., dissenting); id. at 79 U. S. 647, 79 U. S. 650 (Field, J., dissenting); Bronson v. Rodes, 7 Wall. 229, 74 U. S. 246, 74 U. S. 249 (1869); see generally Hepburn v. Griswold, 8 Wall. at 75 U. S. 607-608; Ogden v. Saunders, 12 Wheat. 213, 25 U. S. 265 (1827). Gold was money:
"an universal medium or common standard, by a comparison with which the value of all merchandise may be ascertained, or it is a sign which represents the respective values of all commodities."
1 W. Blackstone, Commentaries *276. The fluctuating and uncertain value of paper money, a fact long taken as gospel, e.g., J. Mill, Principles of Political Economy 542-563 (1936); The Legal Tender Cases, 12 Wall. at 79 U. S. 679 (Field, J., dissenting); Bronson v. Rodes, 7 Wall. at 74 U. S. 246; Craig v. Missouri, 4 Pet. 410, 29 U. S. 432 (1830), and a point hit home by the rampant inflation which had been decimating the paper currencies of Europe, including France, during the post- World War I era, led the Convention expressly to reject such a standard of value.
The purpose and effect of gold clauses such as that contained in the Convention were not only well known in this country at the time the United States adhered to the Convention, such gold clauses were actually made unlawful in 1933. Congress declared that
"every provision contained in or made with respect to any obligation which purports to give the obligee
a right to require payment in gold or a particular kind of coin or currency, or in an amount in money of the United States measured thereby, . . . to be against public policy. . . ."
Joint Resolution of June 5, 1933, 48 Stat. 113, 31 U.S.C. § 463(a) (1976 ed.). [Footnote 2/3] The important point is that there simply was no question as to the purpose and effect of such a clause, absent some valid exercise of governmental power over the currency to subvert it. It
"calls for the payment of value in money, measured by a stated number of gold dollars of the standard defined in the clause. Feist v. Societe Intercommunale Belge d'Electricite,  A. C. 161, 170-173; Serbian and Brazilian Bond Cases, P.C.I.J., series A. Nos. 20-21, pp. 32-34, 109-119. In the absence of any further exertion of governmental power, that obligation plainly could not be satisfied by payment of the same number of dollars, either specie or paper, measured by a gold dollar of lesser weight, regardless of their purchasing power or the state of our internal economy at the due date."

S. 364 (McReynolds, J., dissenting) (gold clauses intended to afford definite standard or measure of value and thus guard against fluctuations in currency); see generally Guaranty Trust Co. v. Henwood, 307 U. S. 247 (1939).
The United States did not participate in the Warsaw proceedings, though it did send an observer. The Aeronautics
Branch of the Commerce Department studied the Convention and communicated with United States air carriers, who universally gave it their strong support. Lowenfeld & Mendelsohn, The United States and the Warsaw Convention, 80 Harv.L.Rev. 497, 502 (1967). The President submitted the Convention to the Senate in 1934, which gave its advice and consent by voice vote without committee hearings, committee reports, or floor debate. 78 Cong.Rec. 11582 (1934).
The Warsaw Convention's limitation on liability for damage to cargo has not been altered in the past half-century so far as the United States is concerned: the United States continues to adhere to the Convention as drafted in 1929.
Conditions in the world of aviation are, of course, radically different than they were 50 years ago. The Spirit of St. Louis, and the age of aviation it represents, are relics of the past. What was then a startling and daring feat for "Lucky Lindy" is now a humdrum occurrence for millions of travelers. Air travel is among the safest forms of transportation, and the fledging venture of a half century ago is a major, established international industry today. Nevertheless, though application of the Warsaw Convention's liability limitation is anachronistic in today's world of aviation, we are obliged to enforce it so long as the political branches of the Government adhere to the Convention. The maxim that cessante ratione legis, cessat et ipsa lex, applicable to the common law, does not govern the judiciary in cases involving application of positive law.
Conditions in the world of finance are, of course, also radically different than they were 50 years ago, when the nations of the world were attempting to reinstitute the international gold exchange standard, abandoned at the outbreak of World War I. The gold standard as a stable medium of international exchange, and the use of gold as an official standard of value for domestic purposes, are relics of the past. What has not changed, however, is the concept of a standard of value, and the effect of adopting one item as the standard as
opposed to another. A relic though a gold standard may be, it was the standard adopted by the Convention. The delegates to that Convention were schooled not in the theories of John Maynard Keynes, but rather in the accepted learning of John Stuart Mill. We are as obliged to apply the standard of value agreed upon by the Convention as we are obliged to apply the liability limitation. [Footnote 2/4] Indeed, of course, it is meaningless
to attempt to speak of one without the other: a liability limitation has no meaning without reference to a standard of value.
"The value of a thing is what it will exchange for: the value of money is what money will exchange for; the purchasing power of money."
J. Mill, Principles of Political Economy 489 (1936). The United States, of course, clung to a gold standard until recently. That is, gold was, at least in theory, an official standard of value for the currency, and hence the number of dollars which would exchange for a given amount of gold was set by law. When the "price" of gold was fixed by law, the conversion of French francs, merely a sum of gold, into United States dollars, also merely a sum of gold, was determined by law. See generally 90 U. S. Richards, 23 Wall. 246 (1875). Gold has now been demonetized. But the Convention's standard of value remains and the concept of value has not changed. The price of gold is simply no longer fixed by law. Gold, however, still will exchange for dollars. The rate at which a domestic currency exchanges for gold was and is the only "conversion" permitted or anticipated by the Convention. That figure is the liability limitation of the Warsaw Convention.
The $9.07-per-pound limit set in TWA's tariff is void under Article 23 of the Convention, which nullifies "[a]ny provision tending to relieve [a] carrier of liability or to fix a lower limit than that which is laid down in this convention." That tariff is no less void because it was accepted by the CAB. E.g., 49 U.S.C. § 1502 (CAB must exercise its authority over tariffs
"consistently with any obligation assumed by the United States in any treaty, convention, or agreement that may be in force between the United States and any foreign country or foreign countries . . ."). [Footnote 2/5]
The drafters of the Convention would surely have agreed that the
"least covert of all modes of knavery . . . consists in calling a shilling a pound, that a debt of one hundred pounds may be cancelled by the payment of one hundred shillings."
J. Mill, Principles of Political Economy 486 (1936). Basically, TWA invites us to call a dime a dollar, in order to cancel
a debt of 80,000 dollars by the payment of 80,000 dimes. We should not accept that invitation.
The approach of the Court to this litigation is quite different from mine. Rather than attempting to ascertain the intent of the Convention and then applying the liability limitation thought appropriate by the Convention, the Court considers its function to make one up, with the aid of the Civil Aeronautics Board, so long as its "choice" is "sufficiently consistent" with the broad "purposes" of the Convention. Ante at 466 U. S. 256. [Footnote 2/6]
The purported textual basis in the Convention for the Court's freewheeling approach to this case is Article 22(4), which permits the sums of gold specified therein to be converted
into an equivalent amount of any national currency. Ante at 466 U. S. 260. The Court, of course, does not convert those sums into dollars; the Court converts the standard of value selected by the Convention into a standard of value expressly rejected by the Convention. In this way, it substitutes a fixed $9.07-per-pound liability limit for a liability limit of a sum of gold per pound. The only relationship between the two figures is a historical one: that is to say, one which no longer exists. [Footnote 2/7]
The Court tells us that the limit agreed to by the Convention is "fluid, uncertain, and altogether inconvenient" in
today's world. Ante at 466 U. S. 260. [Footnote 2/8] If the Convention as drafted is unworkable in today's world, that should not be surprising. To paraphrase the majority, it was written for a few years, not for a half century of the most rapid and fundamental changes in the history of the planet. The majority takes the Convention written for a few years in the era of the Spirit of St. Louis, and rewrites it in the hope, I presume, that it will last a few more years into the age of the Space Shuttle. Just why it does so escapes me. The question whether that needs to be done, and the question whether that should be done, are simply not decisions for this Court to make.
The Court reaches its singularly peculiar result by concluding that the method of limiting liability chosen by the Convention would fail to effect any purpose of the Convention's framers in light of the contemporary domestic and international monetary structure. Ante at 466 U. S. 255. [Footnote 2/9] Ironically, in
essence, the Court agrees with the rationale of the Court of Appeals: that the limit is unenforceable on grounds of frustration of purpose. The Court differs with the Court of
Appeals only in terms of the remedy. Whereas the Court of Appeals thought the appropriate remedy to be rescission of the agreement, the Court thinks the appropriate remedy is reformation of the agreement. Of course, if the premise of the Court is correct, and the liability limitation is unworkable in today's world, there is but one remedy: amendment of the Convention by the parties. [Footnote 2/10]
Some students of the Court take for granted that our decisions represent the will of the judges, rather than the will of the law. [Footnote 2/11] This dogma may be the current fashion, but I remain convinced that such remarks reflect a profound misunderstanding of the nature of our work. Unfortunately, however, cynics -- parading under the banner of legal realism -- are given a measure of credibility whenever the Court bases a decision on its own notions of sound policy, rather
than on what the law commands. [Footnote 2/12] It does so today. [Footnote 2/13] The task of revising an international treaty is not one that this Court has any authority to perform. I respectfully dissent.
These fears were epitomized by the crash of the Hindenberg in 1937, though the Warsaw Convention's liability limitation could not save the dirigible -- then a significant mode of international air transportation -- from rapid extinction. See generally L. Ege, Balloons and Airships 176-221 (1973); D. Robinson, Giants in the Sky 250-315 (1973).
The liability limitation, it may be noted, was not limited to damages arising from special risks of an aircraft crash, nor did it fully protect carriers from those special risks. With respect to parties contracting with air carriers to ship goods, the Convention wrote with a broad brush: limiting liability as well for the kind of damage to goods that would be as likely to occur in any mode of transportation -- such as the loss of a single item of cargo in connection with a safe flight. On the other hand, the Convention provided air carriers with no special protection whatsoever vis-a-vis third parties who might be injured by air crashes.
These units, it so happened, corresponded to the French franc as defined by a 1928 French statute. It was thus convenient to call them francs, and the Convention did so. That French statute, however, could have been repealed the day after the delegates adjourned their meeting, and it would not have affected the liability limitation. For the delegates had selected as the standard of value a commodity with a value independent of any one nation's control; indeed, a commodity perceived to have "intrinsic" value -- a commodity individuals had valued before there were nations, and would value whether or not national governments made it an official medium of exchange.
Since the Convention was adhered to by the United States subsequent to the passage of this statute, presumably the Convention was an exception to this prohibition, unless we are to indulge the inference that Congress simultaneously abrogated and ratified the Convention. In any event, this statute has been repealed with respect to obligations incurred after October 27, 1977. 31 U.S.C. § 5118(d)(2). See 123 Cong.Rec. 33219-33220 (1977).
A staff memorandum addressed to the Civil Aeronautics Board on March 18, 1980, by the Chief, Policy Development Division, contains this telling comment on the background of the Warsaw liability limits and their contemporary relevance:
"The Warsaw Convention was negotiated during the late 1920's, when the aviation industry was in its infancy. The minutes of the negotiations show that the primary concerns of the drafters are no longer of great importance to the industry. In addition, their assumptions about how the liability limitation mechanism would work were erroneous."
"In 1929, air travel was perceived by the public and, more importantly, by insurance companies to be an extremely risky mode of transportation. A major justification for limiting liability was that, unless carriers could present potential insurers with some degree of predictability in estimating damages from aircraft accidents, they would have great difficulty in obtaining coverage. Furthermore, the delegates had little sympathy for anyone foolish enough to board an airplane without enough personal insurance to provide for his widow (or her widower) and children should the plane crash. Over the years, air travel has become one of the safest modes of transportation, and airlines, even those operating under circumstances where they cannot limit their liability for death or personal injury, have no special difficulties finding insurers."
"The minutes also reflect the delegates' rationale for using gold as the unit of reference in determining carrier liability limits, instead of pegging the limits to some particular currency like the dollar or the franc, with no reference to the metal. . . ."
"Warsaw has become an anachronism, yet various attempts to amend it have become stalled by the ratification process. While the Guatemala and Montreal Protocols would have revised the limits upward, the proposed limits were still relatively low, and none of the proposals contained a mechanism that would provide for periodical adjustments to compensate for inflation. Article 22 tied to gold, however, overcompensates for inflation to the point that the industry may view it as a sort of passengers' affirmative action plan that is supposed to make up for years of unreasonably low limits. Although gold-based limits may not be the most rational approach to allocating risks between carriers and consumers of international air transportation, the framers of Warsaw deliberately adopted this approach -- expressly rejecting a dollar or some other currency-based system -- and probably left us no flexibility as long as Warsaw remains in effect."
App. 49-51 (footnote omitted).
The majority asks why the CAB was "disqualified from setting a similar conversion rate one year after Congress stopped doing so." Ante at 466 U. S. 255, n. 26 (emphasis supplied). So framed, the majority's question seems to answer itself. What the majority ignores is that the powers delegated to the CAB, 49 U.S.C. § 1502, previously quoted supra, must be exercised consistently with any convention in force, including the Warsaw Convention.
Although the Court makes a ritual of referring to the "CAB's choice" in its opinion (implying that it might not have made the same choice independently), ante at 466 U. S. 255, 466 U. S. 256, 466 U. S. 257, 466 U. S. 258, 466 U. S. 259, this is a suit between two private parties, not a declaratory judgment action challenging the CAB's exercise of its authority over tariffs. If it were, one would frame the question as whether the CAB has exercised its authority consistently with the Convention, though that is not how the majority frames the question presented at the outset of its opinion. Ante at 466 U. S. 245. In any event, the answer to that question, of course, turns on what the Convention means. On this matter, the CAB's views are not entitled to any special deference. While the Convention is a limitation on the CAB's powers, the CAB is not the governmental organ charged with enforcing the liability limitation -- that responsibility rests with the courts of the United States. The Solicitor General correctly observes:
"The Warsaw Convention is a self-executing treaty that provides a source of rules of decision applicable in United States courts without requiring enactment of any supplementary implementing legislation by Congress."
Brief for United States as Amicus Curiae 16. Courts, not the CAB, render money judgments, and in rendering those money judgments, courts must apply the rules of decision provided by the Convention. Furthermore, even if some deference were to be accorded to the CAB's views, the CAB's position would have to be rejected, since it conflicts with the plain meaning of the Convention.
The Court does speak of intent at the close of its opinion. Ante at 466 U. S. 260. Its approach to ascertaining intent is novel, to say the least. It postulates the general "purposes" of the liability limitation. It then divines the effects of a gold-based liability in today's world. It finds the general purposes inconsistent with a gold-based limitation, and concludes that the Convention did not intend to adopt a gold-based limitation. The rather telling deficiency with this conclusion is that the Convention did adopt a gold-based limitation. The Court itself must recognize this defect, for it tells us that, to achieve their purposes, "the Convention's framers chose an international, not a parochial, standard, free from the control of any one country." Ante at 466 U. S. 256 (footnote omitted). Inexplicably, however, the Court then proceeds to ignore the standard the Convention selected. It does rely upon the practice of the signatories between 1934 and 1978. Ante at 466 U. S. 259. Our practice was consistent with the Convention so long as the price of gold was set by law. It is no longer. One commentator argued prior to the total demonetization of gold that the market price of gold should have been used in light of the economic reality of the early 1970's, see Heller, The Warsaw Convention and the "Two-Tier" Gold Market, 7 J.World Trade L. 126 (1973); Heller, The Value of the Gold Franc -- A Different Point of View, 6 J.Mar.L. & Com. 73 (1974). The response to that argument rested on the fact that the price of gold was set by law -- a fact that no longer obtains. See Boehringer Mannheim Diagnostic, Inc. v. Pan American World Airway, Inc., 531 F.Supp. 344, 353, n. 46 (SD Tex.1981), appeal docketed, No. 81-2519 (CA5, Dec. 30, 1981).
The majority is correct in stating that I have no problem with the conclusion that our practice was consistent with the Convention when the price of gold was set by law. Ante at 466 U. S. 254-255, n. 26. We need not speculate on that score, for, at the outset of the Warsaw proceedings, the drafters performed the very kind of conversion they anticipated would occur when a national currency was based on the gold standard -- they converted the sums expressed in gold francs in the draft proposal into equivalent sums of new French francs.
The Convention did not, of course, deprive a signatory sovereign nation of its control over its own currency. Indeed, it was a recognition of that authority which led the Swiss delegate to insist that a sum of gold -- rather than a reference to the 1928 French statute -- be specified in the Convention. Congress has plenary power over our currency. See, e.g., 79 U. S. 12 Wall. 457 (1871). In exercising that power, it may define the dollar in terms of gold. In doing so, and in periodically adjusting that relationship, it necessarily affects legal interests in many contractual areas. See, e.g., Norman v. Baltimore & Ohio R. Co., 294 U. S. 240 (1935). For example, when Congress passed the Par Value Modification Act in 1972, setting a new price of gold, Congress "did not suggest that the CAB should thereafter use a different conversion factor" for Warsaw Convention purposes, but "the CAB did, of course, use that price to translate the Convention's gold-based liability limit into dollars." Ante at 466 U. S. 255. This was the only "flexible implementation" of the treaty which occurred from 1934 to 1978. Ante at 466 U. S. 259. The CAB, of course, had no flexibility -- air carriers were bound by the Convention, and bound by Congress' decisions on monetary policy, see, e.g., Norman v. Baltimore Ohio R. Co., supra. Congress has most recently exercised its authority over the currency by demonetizing gold completely. That has legal consequences as well. One of those consequences is that the rate of exchange between dollars and gold is no longer determined by law, and it is irrelevant that, when Congress repealed the Par Value Modification Act it "did not suggest that the CAB should thereafter use a different conversion factor" for Warsaw Convention purposes. Congress has not delegated its authority over the currency to the CAB. And Congress clearly has not delegated authority to the CAB to violate Article 23 of the Convention -- it has expressly stated that the CAB's authority must be exercised consistently with our treaty obligations. Congress itself, of course, does not have the authority to violate Article 23 short of repudiating the Convention. Congress naturally could repudiate the Convention and set its own liability limitation through domestic legislation, but has not done so.
The Court might as well have selected a figure corresponding to the dollar value of 12 grams of gold in 1929, or 1934, as that existing in 1978. Indeed, if the Court fancies itself competent to decide the proper liability limit necessary to effect the "purposes" of the Convention, one wonders why it selects a figure which happens to correspond to a value of a given amount of gold at any point in time. Since it adopts such a freewheeling approach to the subject, the Court could, for example, compute the liability limit in the same basic manner as did the Convention -- dividing the declared value of all air cargo by the tonnage, and then doubling that figure to arrive at a per-pound limitation.
Any fixed dollar figure lower than the actual damage figure, of course, would meet all of the purposes postulated by the Court as well as $9.07 per pound. But it appears that the Court will be willing to modify the limit it has set from time to time, for it states that its limit
"might require periodic adjustment . . . to account both for the dollar's changing value relative to other Western currencies and, if necessary, for changes in the conversion rates adopted by other Convention signatories."
Ante at 466 U. S. 256. The only reason the Court apparently does not make such an adjustment is that, since 1978, "no substantial changes of either type have occurred." Ibid. Of course, if the standard adopted by the Convention were enforced, rather than ignored, no such adjustments would need to be made by courts -- for as the Court candidly admits, "[s]ince gold is freely traded on an international market, its price always provides a unique and internationally uniform conversion rate." Ante at 466 U. S. 258. The fact that gold has always had a uniform value -- since, to use the words of the Swiss delegate, there is but one quality of gold -- was, of course, a major reason why it was chosen as a standard of value in an international agreement setting an internationally enforceable limitation on liability.
Compare ante at 466 U. S. 253 ("[W]hen the parties to a treaty continue to assert its vitality a private person who finds the continued existence of the treaty inconvenient may not invoke the doctrine [of rebus sic stantibus] on their behalf").
The response of the framers to this assertion by the majority, I am quite sure, would be "au contraire." Indeed, on the face of the majority opinion, only one of the purposes the Court identifies is not served by the gold standard -- that of a stable and predictable limit. The other purposes, setting some limit, setting an internationally uniform limit, and linking the limit to a real value, are all achieved by the limit adopted by the Convention. In fact, the Court concedes the first purpose is served by any standard, ante at 466 U. S. 256, and seems to agree that the latter two purposes are better achieved by the limit adopted by the Convention, ante at 466 U. S. 258-259. Hence, even if I were to adopt the freewheeling approach of the Court to the question before us -- that is, an independent judicial determination of which of several "choices" would "best effect" the "different and to some extent contradictory" general "purposes" of the Convention -- I would find the Court's "choice" unpersuasive.
Gold was selected because it would continue to be an internationally recognized standard of value, irrespective of what national governments did with respect to their currencies. It was also selected to guard against the fluctuating values of currencies. Gold continues to be an internationally recognized standard of value. The legacy of eons is not readily discarded. See generally 1 Report to Congress of the Commission on the Role of Gold in the Domestic and International Monetary Systems 98 (Mar.1982); M. Friedman & A. Schwartz, A Monetary History of the United States 473, 684 (1971). Its nominal value is still overwhelmingly its value in exchange, not its value in use -- it is not simply another commodity. Fort Knox does not house any pork bellies. Currencies are worth far less in relation to gold than they were several years ago, that is, in perhaps bygone jargon, the currencies have been substantially devalued. The variation in the relative value of gold to currencies is not the kind of variation in value that the framers of the Convention wanted to avoid -- it is one that they desired. Certainly, however, the extent of the current variation is more than they could have anticipated, and currencies have not devalued in overall purchasing power to the extent that they have in relation to gold.
The Court, in support of the standard it has selected -- the dollar -- thinks that the relative value of various currencies has remained relatively stable in recent years (a conclusion one cannot reach based on the data relied upon by the majority). Even if that were true, all that would mean is that the currencies have not depreciated in relation to one another -- it does not mean that the currencies have not devalued. The real value of those currencies has not been stable, it has been declining. The real value of gold has not been stable either, but it has not declined since 1929. The same manifestly cannot be said of the dollar.
The interests in stability and predictability, of course, do favor the Court's choice. But the fact that the market price of gold fluctuates on a daily basis does not seem to me to present particularly serious problems. Indeed, the existence of a well-recognized daily price provides a simple point of reference for computing the exact amount of the limit on the date of shipment. The calculation of insurance rates would have to take into account the variable character of the gold market, but that is hardly a matter that underwriters are incapable of evaluating realistically. And, of course, the problem of computing their contingent tort liability for cargo would remain less difficult than the problem they confront in computing their contingent tort liability to third parties.
The idea that air transport users and carriers are forced to become unwilling speculators in the gold market is mere rhetoric. It stands history on its head even to suggest that the Warsaw Convention's liability limit has been foisted upon air carriers against their will. If, because of the demonetization of gold, the gold standard makes air carriers "speculators" in the gold market, and if the air carriers find this situation unacceptable, they can urge modification of the Convention. But, of course, they have already failed to secure Senate approval of the Montreal Protocols. Today, their attorneys win the battle that their lobbyists lost.
Incredibly, the majority apparently derives some comfort from the fact that the liability limit it adopts is approximately equivalent in purchasing power to that contained in the Montreal Protocols, doing so in spite of the fact that the Montreal Protocols were rejected by the Senate. See ante at 466 U. S. 256-257. Indeed, the CAB accepts tariffs based on the Montreal Protocols, which passes by the majority without criticism. Ante at 466 U. S. 257, n. 29.
For example, one law professor recently wrote in a doctrinaire fashion:
"Modern jurisprudence regards the distinction Marshall Court justices sought to make between the 'will of the judge' and the 'will of the law' as a distinction without a difference. The 'legal' decisions of judges are, in the modern consciousness, necessarily personal and creative. . . ."
". . . All of the modern canons for judicial behavior, and all of the modern theories of judicial performance, presuppose that judges 'make' law and that judicial will and legal will are thus inseparable."
White, The Working Life of The Marshall Court, 1815-1835, 70 Va.L.Rev. 1, 49-50 (1984).
Judges, of course, must perform a lawmaking function, even in cases involving statutory construction. See, e.g., R. Pound, The Spirit of the Common Law 170-15 (1921). But the limits of our authority and our ability to develop the law should always be respected. As Justice Cardozo explained:
"No doubt there is a field within which judicial judgment moves untrammeled by fixed principles. Obscurity of statute or of precedent or of customs or of morals, or collision between some or all of them, may leave the law unsettled, and cast a duty upon the courts to declare it retrospectively in the exercise of a power frankly legislative in function. . . . We must not let these occasional and relatively rare instances blind our eyes to the innumerable instances where there is neither obscurity nor collision nor opportunity for diverse judgment. . . . In countless litigations, the law is so clear that judges have no discretion. They have the right to legislate within gaps, but often there are no gaps. We shall have a false view of the landscape if we look at the waste spaces only, and refuse to see the acres already sown and fruitful. I think the difficulty has its origin in the failure to distinguish between right and power, between the command embodied in a judgment and the jural principle to which the obedience of the judge is due. Judges have, of course, the power, though not the right, to ignore the mandate of a statute, and render judgment in despite of it. They have the power, though not the right, to travel beyond the walls of the interstices, the bounds set to judicial innovation by precedent and custom. Nonetheless, by that abuse of power, they violate the law."
B. Cardozo, The Nature of the Judicial Process 128-129 (1921).
Perhaps the majority would insist that it is merely deferring to the CAB's notions of wise policy. If so, this would mean that the CAB could have made another choice to which the majority would have deferred. But surely the majority would not countenance selection of the choice made by the Convention itself, for the majority believes that choice would fail to effect any of the Convention's purposes. Moreover, I cannot see how the majority could defer to a choice of the limit set forth in the Montreal Protocols, given the fact that the Senate has recently rejected the Montreal Protocols. But see n.
