The principles of
Almeida-Sanchez v. United States,
413 U. S. 266,
that the Fourth Amendment prohibits the Border Patrol from using
roving patrols to search vehicles, without a warrant or probable
cause, at points removed from the border and its functional
equivalents, will not be applied retroactively to invalidate
searches that occurred prior to the date of that decision.
United States v. Peltier, ante, p.
422 U. S. 531. As
the Court of Appeals in this case correctly decided that
Almeida-Sanchez did not apply retroactively, petitioner is
not entitled to the benefit of that court's further but unnecessary
ruling that
Almeida-Sanchez extended to searches at
traffic checkpoints. Pp.

MR. JUSTICE POWELL delivered the opinion of the Court.
Petitioner was convicted of federal drug offenses based on
evidence seized in January, 1971, when Border Patrol officers
stopped his camper pickup at a traffic checkpoint on California
Highway 86, about 36 air miles from the Mexican border. The
officers first determined that petitioner was a United States
citizen, then asked him to open the camper so that they could
search for concealed aliens. When petitioner opened the door, one
officer noticed a strong odor of marihuana. He entered the camper
and discovered approximately 356 pounds of the drug. A subsequent
search of the passenger compartment produced a number of benzedrine
tablets.
The Court of Appeals for the Ninth Circuit affirmed petitioner's
conviction, rejecting his argument that the search was unlawful.
462 F.2d 347 (1972). A petition for certiorari was pending when we
announced our decision in
Almeida-Sanchez v. United
States, 413 U. S. 266
(1973), holding that the Fourth Amendment prohibits the use of
roving patrols to search vehicles, with neither a warrant nor
probable cause, at points removed from the border and its
functional equivalents. We vacated the judgment in petitioner's
case and remanded for reconsideration in light of
Almeida-Sanchez. 413 U.S. 915 (1973).
The Court of Appeals reheard the case en banc and held, in a
sharply divided opinion, that the principles of
Almeida-Sanchez applied to searches conducted at traffic
checkpoints, as well as searches conducted by roving patrols. The
Court nevertheless affirmed petitioner's conviction, holding that
Almeida-Sanchez would not be applied to invalidate
searches that occurred prior to the date of that decision. 500 F.2d
960 (1974). We
Page 422 U. S. 918
granted certiorari to resolve an apparent conflict with the
Court of Appeals for the Tenth Circuit in
United States v.
King, 485 F.2d 353 (1973), and
United States v.
Maddox, 485 F.2d 361 (1973).
We hold today in
United States v. Ortiz, ante, p.
422 U. S. 891,
that the Fourth Amendment, as interpreted in
Almeida-Sanchez, forbids searching cars at traffic
checkpoints in the absence of consent or probable cause. In this
case, the Government does not contend that the Highway 86
checkpoint is a functional equivalent of the border, that the
officers had probable cause to open the camper, or that petitioner
consented to the search. The primary question for decision is
whether the principles of
Almeida-Sanchez should have been
applied retroactively.
In
United States v. Peltier, ante, p.
422 U. S. 531, we
refused to apply
Almeida-Sanchez to a roving patrol search
conducted before June 21, 1973, even though a direct appeal was
pending on that date. We think the decision in
Peltier is
controlling here, as the reasons that dictated a holding of
nonretroactivity in that case are equally applicable. At the time
of our decision in
Almeida-Sanchez, all the Courts of
Appeals in Circuits adjacent to the Mexican border had held that
immigration officers at traffic checkpoints could search
automobiles for concealed aliens.
E.g., United States v.
McCormick, 468 F.2d 68 (CA10 1972);
United States v. De
Leon, 462 F.2d 170 (CA5 1972);
Fumagalli v. United
States, 429 F.2d 1011 (CA9 1970). [
Footnote 1] This Court had
Page 422 U. S. 919
not ruled on the question, and no contrary precedent was
reported in other Courts of Appeals. The Border Patrol reasonably
relied on the decisions of the Court of Appeals in performing the
search in this case an others like it, and, in these circumstances,
the purposes of the Fourth Amendment exclusionary rule would not be
served by applying the principles of
Almeida-Sanchez
retroactively.
Petitioner further argues that, even if
Almeida-Sanchez
Page 422 U. S. 920
is not to be applied retroactively, he is entitled to the
benefit of the Court of Appeals' decision that
Almeida-Sanchez extended to checkpoint searches. He
invokes this Court's practice of applying new constitutional
doctrine in the case that establishes the point, [
Footnote 2] and maintains that the Court of
Appeals' refusal to apply its extension of
Almeida-Sanchez
in his case made its discussion of that point mere dictum. We
conclude, however, that the only error of the Court of Appeals was
its reaching out to decide that
Almeida-Sanchez applied to
checkpoint searches in a case that did not require decision of the
issue.
The Government raised two questions in the Court of Appeals:
whether
Almeida-Sanchez applied retroactively, and, if it
did, whether it would require probable cause for checkpoint
searches. This Court consistently has declined to address unsettled
questions regarding the scope of decisions establishing new
constitutional doctrine in cases in which it holds those decisions
nonretroactive.
E.g., Michigan v. Payne, 412 U. S.
47,
412 U. S. 49-50
(1973);
DeStefano v. Woods, 392 U.
S. 631 (1968). This practice is rooted in our reluctance
to decide constitutional questions unnecessarily.
See United
States v. Raines, 362 U. S. 17,
362 U. S. 21
(1960);
Ashwander v. TVA, 297 U.
S. 288,
297 U. S.
346-347 (1936) (Brandeis, J., concurring). Because this
reluctance, in turn, is grounded in the constitutional role of the
federal courts,
United States v. Raines, supra, the
district courts and courts of appeals should follow our practice,
when issues of both retroactivity and application of constitutional
doctrine are raised, of deciding the retroactivity issue first. As
the
Page 422 U. S. 921
Court of Appeals correctly decided in this case that
Almeida-Sanchez did not apply to a 1971 search, it should
have refrained from considering whether our decision in that case
applied to searches at checkpoints.
Petitioner contends, nevertheless, that, once the Court of
Appeals addressed the unnecessary issue, it was bound to apply that
ruling in his case. Because it refused to do so, petitioner says
the court rendered a hypothetical decision forbidden by Art. III of
the Constitution. It is true that this Court has suggested that
Art. III is the primary impetus for applying new constitutional
doctrines in cases that establish them for the first time.
Stovall v. Denno, 388 U. S. 293,
388 U. S. 301
(1967). But petitioner's case is altogether different.
Almeida-Sanchez already had established the principle, and
there was a genuine controversy between petitioner and the United
States over its retroactive application. Contrary to petitioner's
assertion, the court's jurisdiction to resolve that controversy
could not be dislodged by its discussion of an unnecessary
issue.
The judgment of the Court of Appeals is
Affirmed.
MR. JUSTICE DOUGLAS dissents for the reasons stated in his
dissent in
United States v. Peltier, ante, p.
422 U. S.
543.
MR. JUSTICE BRENNAN and MR. JUSTICE MARSHALL dissent, and would
reverse substantially for the reasons expressed in MR. JUSTICE
BRENNAN's dissent in
United States v. Peltier, ante, p.
422 U. S.
544.
MR. JUSTICE STEWART dissents.
[
Footnote 1]
While approving checkpoint searches for aliens, the Court of
Appeals for the Ninth Circuit had limited the Border Patrol's
authority to search for contraband at points away from the border.
E.g., Cervantes v. United States, 263 F.2d 800 (1959);
see Fumagalli v. United States, 429 F.2d 1011 (1970). The
search of petitioner's camper was not invalid under these cases,
because the agent was engaged in a search for aliens, legal under
the Ninth Circuit's decisions, when he developed probable cause to
believe that the camper contained marihuana.
There was some ground for confusion about the state of the law
in the Fifth Circuit at the time
Almeida-Sanchez was
decided. Early cases had affirmed immigration officers' authority
to search for aliens at traffic checkpoints.
E.g., Ramirez v.
United States, 263 F.2d 385 (1959);
Kelly v. United
States, 197 F.2d 162 (1952). Later cases took the same view,
e.g., United States v. De Leon, 462 F.2d 170 (1972),
although one opinion seemed to hold that the authority to search at
checkpoints was qualified by a requirement that the location and
operation of the checkpoint be reasonable.
United States v.
McDaniel, 463 F.2d 129, 133 (1972). Two decisions by other
panels of the court ambiguously suggested that a search at a
checkpoint must be supported by "reasonable suspicion."
United
States v. Wright, 476 F.2d 1027 (1973);
United States v.
Maggard, 451 F.2d 502 (1971). But a later opinion seemed to
adopt the Ninth Circuit's distinction between searches for aliens
and searches for contraband, suggesting that immigration searches
could be made without suspicion, while customs searches required a
foundation for believing that the particular car contained
contraband.
United States v. Thompson, 475 F.2d 1359, 1362
(1973).
Neither of the cases suggesting that "reasonable suspicion" was
required for immigration searches resulted in a decision
invalidating a search, and none of the court's opinions indicated
disagreement with the earlier cases establishing an unqualified
right to search for aliens at checkpoints whose location and
operation were reasonable. Under these circumstances, we conclude
that the Government reasonably relied on the earlier cases in
continuing to make immigration searches at checkpoints.
