You need to look a bit harder then. It has been upheld by the Supreme Court:
U.S. Supreme Court
UNITED STATES v. MARTINEZ-FUERTE, 428 U.S. 543 (1976)
428 U.S. 543
UNITED STATES v. MARTINEZ-FUERTE ET AL.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT
Argued April 26, 1976
Decided July 6, 1976*
MR. JUSTICE POWELL delivered the opinion of the Court.
These cases involve criminal prosecutions for offenses relating to the transportation of illegal Mexican aliens. Each defendant was arrested at a permanent checkpoint operated by the Border Patrol away from the international border with Mexico, and each sought the exclusion of certain evidence on the ground that the operation of the checkpoint was incompatible with the Fourth Amendment. In each instance whether the Fourth Amendment was violated turns primarily on whether a vehicle may be stopped at a fixed checkpoint for brief questioning of its occupants even though there is no reason to believe the particular vehicle contains illegal aliens. We reserved this question last Term in United States v. Ortiz, 422 U.S. 891, 897 n. 3 (1975). We hold today that such stops are consistent with the Fourth Amendment. We also hold that the operation of a fixed checkpoint need not be authorized in advance by a judicial warrant.
