<P> The Fourth Amendment ( Amendment IV ) to the United States Constitution is part of the Bill of Rights that prohibits unreasonable searches and seizures . It requires `` reasonable '' governmental searches and seizures to be conducted only upon issuance of a warrant , judicially sanctioned by probable cause , supported by oath or affirmation , particularly describing the place to be searched and the persons or things to be seized . Under the Fourth Amendment , search and seizure ( including arrest ) should be limited in scope according to specific information supplied to the issuing court , usually by a law enforcement officer who has sworn by it . Fourth Amendment case law deals with three issues : what government activities constitute `` search '' and `` seizure '' ; what constitutes probable cause for these actions ; and how violations of Fourth Amendment rights should be addressed . Early court decisions limited the amendment 's scope to a law enforcement officer 's physical intrusion onto private property , but with Katz v. United States ( 1967 ) , the Supreme Court held that its protections , such as the warrant requirement , extend to the privacy of individuals as well as physical locations . Law enforcement officers need a warrant for most search and seizure activities , but the Court has defined a series of exceptions for consent searches , motor vehicle searches , evidence in plain view , exigent circumstances , border searches , and other situations . </P>
