Von Cleef v. New Jersey

Background

The case involves two people convicted in New Jersey of running a house for lewd conduct and possessing obscene publications. One defendant was arrested on the third floor of a three‑story, 16‑room house. Without a warrant, several officers spent about three hours searching the entire house and seized several thousand items, including books, magazines, catalogues, mailing lists, opened and unopened private correspondence, photographs, drawings, and film. Many of those items were later used at trial.

Reasoning

The central question was whether that wide, warrantless search could be justified as a search incident to a valid arrest. The Court examined earlier cases that allowed more limited searches of small business rooms or apartments. It concluded that those precedents did not justify combing a 16‑room house from top to bottom and hauling away thousands of papers. The Court held the searches and mass seizures were constitutionally invalid under the Fourth Amendment and reversed the convictions, then sent the case back for further proceedings.

Real world impact

The decision prevents police from treating large private homes like small business rooms when making searches incident to arrest. Evidence gathered by such broad, warrantless searches may be excluded and cannot support convictions. The opinion leaves open further proceedings in the lower courts consistent with this ruling.

Dissents or concurrances

Two Justices agreed to review but would not reverse without a hearing. Justice Harlan joined the result but questioned whether the search differed from earlier cases and discussed when new rules should apply to cases before this Court.
