Mancusi v. DeForte

Background

Frank DeForte, a vice president of a Teamsters local, was investigated and later indicted on charges of conspiracy, coercion, and extortion. Before the indictment, the county district attorney served a subpoena on the union; when the union would not produce the records, state officials entered a shared union office without a warrant, seized union books and papers while DeForte protested, and those records were used at his trial leading to conviction. DeForte sought federal habeas relief after state appeals failed, and the Court of Appeals ordered release.

Reasoning

The Court addressed two questions: whether DeForte, though not the owner of the papers, had a right to object to the seizure, and whether the warrantless search was lawful. Relying on earlier decisions about who may expect privacy, the Court held that because DeForte spent a considerable amount of time in the shared office and had custody of the seized papers when they were taken, he could object to the search. The Court then explained that a subpoena signed by the District Attorney was not the same as a warrant issued by a neutral magistrate. Because the officials conducted a general seizure without a judicial warrant, the search was unreasonable and the seized materials could not be used under the exclusionary rule announced in Mapp.

Real world impact

The ruling means people who regularly work in shared offices and have custody of papers can challenge warrantless seizures of those records. Evidence taken from such shared workplace spaces without a warrant may be excluded from criminal trials. This decision resolved DeForte’s habeas claim in his favor and affirmed the Court of Appeals’ order.

Dissents or concurrances

Justice Black (joined by Justice Stewart) dissented, arguing prior law denied such standing to nonowners and warning the new rule would hinder convictions; Justice White also dissented, questioning how far the protected area should extend.
