Summary

Background

On March 6, 1980, customs officers and a state policeman patrolled the Calcasieu River Ship Channel and sighted the Henry Morgan II, a 40-foot sailboat anchored about 18 miles inland. The officers boarded the vessel under a federal statute allowing customs document inspections, smelled burning marijuana, and found burlap-wrapped bales. Two men aboard were arrested; a search uncovered about 5,800 pounds of marijuana and the men were convicted of various importation and distribution crimes.

Reasoning

The central question was whether the Fourth Amendment forbids customs officers from boarding and briefly inspecting a vessel’s documents in waters that provide ready access to the open sea when they have no suspicion of wrongdoing. The Court relied on the statute (19 U.S.C. §1581(a)), historical practice, and a balancing of interests. It found that document checks intrude only modestly, that waterways offering open-sea access make fixed checkpoints impractical, and that vessel documentation rules differ from car licensing. The Court concluded the boarding was “reasonable” and reversed the Court of Appeals, effectively allowing suspicionless boardings for document inspection in such waters.

Real world impact

The decision makes it easier for customs officials to board and check boats in sea-accessible waters without prior suspicion, strengthening tools to detect smuggling and related offenses. The Court rejected arguments that the case was moot despite dismissal of indictments and deportation, explaining a reversal could reinstate convictions and sentences.

Dissents or concurrances

Justice Brennan dissented, arguing the case was moot and warning that allowing random, suspicionless boardings gives police unchecked discretion and unduly weakens Fourth Amendment protections.
