Protecting the U.S. Perimeter: Border Searches Under the Fourth Amendment
Abstract:
The Fourth Amendment requires that a search or seizure conducted by a governmental agent be reasonable and supported by probable cause. The Supreme Court has interpreted the Fourth Amendment to include a presumptive warrant requirement on all searches and seizures conducted by the government. Any violation of these requirements could result in the suppression of any information derived therefrom. The Supreme Court, however, has also recognized situations that render obtaining a warrant impractical or against the publics interest and has accordingly crafted various exceptions to the warrant and probable cause requirements of the Fourth Amendment. Few exceptions to the presumptive warrant and probable cause requirements are more firmly rooted than the border search exception. Derived from the sovereign right to stop and examine persons and property crossing into the country, border searches allow customs officials the flexibility to inspect incoming individuals and their belongings and to interdict incoming contraband without having to inform a magistrate before the search. Border searches can also occur in places other than the actual physical border. Two different legal concepts authorize such searches 1 searches at the functional equivalent of the border and 2 extended border searches. These concepts allow federal officers to conduct border searches even in situations when it is not feasible to conduct the search at the actual point of entry e.g., examining a person upon arrival at a U.S. airport rather than during a mid-flight crossing into the country. Courts have determined that border searches usually fall into two categories-routine and nonroutine- though this analysis may no longer apply to searches of vehicles or personal property.
