Fourth Amendment¶

Summary¶

The Fourth Amendment to the U.S. Constitution limits unreasonable searches and seizures and is a foundational source for privacy and surveillance law.

Verified Facts¶

Amendment IV states: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
Cornell LII describes the amendment as protecting against arbitrary arrests and as the basis for search warrants, stop-and-frisk, wiretaps, surveillance, and related criminal law and privacy topics.
CASE-CARPENTER-V-US is an OIR seed case record addressing Fourth Amendment protection for historical cell-site location records.
