Task: songer_const1

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the most frequently cited provision of the U.S. Constitution in the headnotes to this case. Answer "0" if no constitutional provisions are cited. If one or more are cited, code the article or amendment to the constitution which is mentioned in the greatest number of headnotes. In case of a tie, code the first mentioned provision of those that are tied. If it is one of the original articles of the constitution, code the number of the article preceeded by two zeros. If it is an amendment to the constitution, code the number of the amendment (zero filled to two places) preceeded by a "1". Examples: 001 = Article 1 of the original constitution, 101 = 1st Amendment, 114 = 14th Amendment.

PER CURIAM:
The appellants were convicted of unlawful importation and knowing concealment of heroin in violation of Title 21 U.S.C.A. § 174. The only error asserted is the denial by the District Court of the appellants’ motion to suppress evidence seized by customs officers in a search of appellants’ car at the time of their arrest six miles from the Mexican border occurring minutes after appellants’ re-entry into the United States. The evidence showed that the Customs Agent stationed at the border had reasonable cause to suspect that the appellants were bringing heroin into the United States in a manner contrary to law. He ordered a customs investigator to detain the car and its occupants if it left town. The investigator kept the appellants under constant surveillance except for a brief time when the car was out of sight. This was a valid border search. Valadez v. United States, 5 Cir. 1966, 358 F.2d 721. The requirement of “reasonable cause to suspect” is satisfied if it is shown that the officer who issues the order for the search is possessed of sufficient information to satisfy the test. Cf. Marsh and Martinez v. United States, 5 Cir. 1965, 344 F.2d 317.
The judgment of conviction is
Affirmed.
