The warrantless search of a trailer parked in a Bronx warehouse and unhitched from its cab did not violate the Fourth Amendment, a federal appeals court ruled yesterday.

Prosecutors from the Southern District U.S. Attorney’s Office argued that cocaine discovered in a hidden compartment of the trailer should be admitted as evidence of a drug distribution conspiracy, since the trailer was an inherently mobile vehicle falling under the “automobile exception” to the Fourth Amendment’s warrant requirement.
