Respondent mailed two 12-pound packages of coins at Mt. Vernon,
Washington, near the Canadian border, to addresses in California
and Tennessee, under circumstances arousing suspicion. The type of
mailing was first class, and thus the packages were not subject to
discretionary inspection. A 29-hour detention of the package,
occasioned mainly by the time differential in obtaining information
about the Tennessee addressee before a search warrant was obtained,
caused the Court of Appeals to hold that the coins were improperly
admitted in evidence against respondent, who had been fund guilty
of illegally importing gold coins from Canada.
Held: Under the facts of this case, the 29-hour delay
is not "unreasonable" under the Fourth Amendment. Pp.

MR. JUSTICE DOUGLAS delivered the opinion of the Court.
Respondent, at about 1:30 p.m. on Thursday, March 28, 1968,
mailed two 12-pound packages at the post office in Mt. Vernon,
Washington, a town some 60 miles from the Canadian border. One
package was addressed to a post office box in Van Nuys, California,
and the other to a post office box in Nashville, Tennessee.
Respondent declared they contained coins. Each package
Page 397 U. S. 250
was to be sent airmail registered, and each was insured for
$10,000, a type of mailing that the parties agree was first class,
making them not subject to discretionary inspection. [
Footnote 1]
When the postal clerk told a policeman who happened to be
present that he was suspicious of the packages, the policeman at
once noticed that the return address on the packages was a vacant
housing area of a nearby junior college, and that the license
plates of respondent's car were British Columbia. The policeman
called the Canadian police, who called customs in Seattle. At 3
o'clock that, afternoon, customs called Van Nuys and learned that
the addressee of one package was under investigation in Van Nuys
for trafficking in illegal coins. Due to the time differential,
Seattle customs was unable to reach Nashville until the following
morning, March 29, when Seattle was advised that the second
addressee was also being investigated for the same crime. A customs
official in Seattle thereupon filed an affidavit for a search
warrant for both packages with a United States commissioner, who
issued the search warrant at 4 p.m., and it was executed in Mt.
Vernon at 6:30 p.m., 2 1/2 hours later. Thereupon, the packages
were opened, inspected, resealed, and promptly sent on their
way.
Other evidence showed that respondent had brought the two
packages in from Canada without declaring them. He was tried for
illegally importing gold coins in violation of 18 U.S.C. § 545, and
found guilty and sentenced and fined. On appeal, the Court of
Appeals reversed, holding that the coins were improperly admitted
in evidence because a timely warrant had not been obtained. 414

It has long been held that first-class mail such as letters and
sealed packages subject to letter postage -- as distinguished from
newspapers, magazines, pamphlets, and other printed matter -- is
free from inspection by postal authorities except in the manner
provided by the Fourth Amendment. As stated in
Ex parte
Jackson, 96 U. S. 727,
96 U. S. 733,
decided in 1878:
"Letters and sealed packages of this kind in the mail are as
fully guarded from examination and inspection, except as to their
outward form and weight, as if they were retained by the parties
forwarding them in their own domiciles. The constitutional guaranty
of the right of the people to be secure in their papers against
unreasonable searches and seizures extends to their papers, thus
closed against inspection, wherever they may be. Whilst in the
mail, they can only be opened and examined under like warrant,
issued upon similar oath or affirmation, particularly describing
the thing to be seized, as is required when papers are subjected to
search in one's own household. No law of Congress can place in the
hands of officials connected with the postal service any authority
to invade the secrecy of letters and such sealed packages in the
mail, and all regulations adopted as to mail matter of this kind
must be in subordination to the great principle embodied in the
fourth amendment of the Constitution."
The course of events since 1878 has underlined the relevance and
importance of the Post Office to our constitutional rights. Mr.
Justice Holmes, in
Milwaukee Pub. Co. v. Burleson,
255 U. S. 407,
255 U. S. 437
(dissenting opinion), said that "the use of the mails is almost as
much a part of free speech as the right to use our tongues." We
have emphasized over and over again that, while Congress may
classify the mail and fix the charges
Page 397 U. S. 252
for its carriage, it may not set up regimes of censorship over
it,
Hannegan v. Esquire, Inc., 327 U.
S. 146, or encumber its flow by setting
"administrative officials astride the flow of mail to inspect
it, appraise it, write the addressee about it, and await a response
before dispatching the mail"
to him. [

S. 301,

Yet even first-class mail is not beyond the reach of all
inspection, and the sole question here is whether the conditions
for its detention and inspection had been satisfied. We think they
had been. The nature and weight of the packages, the fictitious
return address, and the British Columbia license plates of
respondent who made the mailings in this border town certainly
justified detention without a warrant while an investigation was
made. The "protective search for weapons" of a suspect which the
Court approved in
Terry v. Ohio, 392 U. S.
1,
392 U. S. 20-27,
even when probable cause for an arrest did not exist, went further
than we need go here. The only thing done here on the basis of
suspicion was detention of the packages. There was at that point no
possible invasion of the right "to be secure" in the "persons,
houses, papers, and effects" protected by the Fourth Amendment
against "unreasonable searches and seizures." Theoretically -- and
it is theory only that respondent has on his side -- detention of
mail could at some point become an unreasonable seizure of "papers"
or "effects" within the meaning of the Fourth Amendment. Detention
for 1 1/2 hours -- from 1:30 p.m. to 3 p.m. -- for an investigation
certainly was not excessive, and, at the end of that time, probable
cause existed for believing that the California package was part of
an illicit project. A warrant could have been obtained that
Page 397 U. S. 253
day for the one package, yet the mystery of the other package
remained unsolved, and federal officials in Tennessee could not be
reached, because of the time differential. The next morning, they
were reached, and it was learned that the second package was also
probably part of an illicit project. By 4 p.m. -- or 26 1/2 hours
after the mailing in Mt. Vernon -- a search warrant was obtained in
Seattle, and at 6:30 p.m., or 29 hours after the mailing, the
search warrant reached Mt. Vernon, a speedy transmission
considering the rush-hour time of day and the congested
highway.
No interest protected by the Fourth Amendment was invaded by
forwarding the packages the following day, rather than the day when
they were deposited. The significant Fourth Amendment interest was
in the privacy of this first-class mail, and that privacy was not
disturbed or invaded until the approval of the magistrate was
obtained.
The rule of our decisions certainly is not that first class mail
can be detained 29 hours after mailing in order to obtain the
search warrant needed for its inspection. We only hold that, on the
facts of this case -- the nature of the mailings, their suspicious
character, the fact that there were two packages going to separate
destinations, the unavoidable delay in contacting the more distant
of the two destinations, the distance between Mt. Vernon and
Seattle -- a 29-hour delay between the mailings and the service of
the warrant cannot be said to be "unreasonable" within the meaning
of the Fourth Amendment. Detention for this limited time was,
indeed, the prudent act, rather than letting the packages enter the
mails and then, in case the initial suspicions were confirmed,
trying to locate them en route and enlisting the help of distant
federal officials in serving the warrant.
Reversed.
