tl;dr: A union official challenged his conviction based on union records seized without a warrant from his shared office. The Supreme Court held he had standing to object because he had a reasonable expectation of privacy in the office, making the warrantless search illegal.

Case Facts & Court Holding

Key Facts & Case Background

Respondent Frank DeForte, a vice president of a Teamsters Union local, was convicted of extortion and other crimes based on evidence seized from his union office. State officials, acting on a district attorney’s subpoena duces tecum, conducted a warrantless search of a large, single-room office that DeForte shared with several other union officials. The union had refused to comply with the subpoena. DeForte was present during the search and objected to it. The officials seized union books and records that were in DeForte’s custody at the time. These records, which belonged to the union and not to DeForte personally, were admitted into evidence against him at trial over his Fourth Amendment objection. After his conviction was upheld in state court, DeForte filed a federal habeas corpus petition, arguing the evidence was obtained through an unconstitutional search and seizure. The Court of Appeals for the Second Circuit agreed and ordered the writ to be issued.
