Precedent Case Law

The collection of prior appellate court decisions with facts similar to a current case, utilized by attorneys to argue how the court should rule and by justices to formulate bench questions.

Agnello v. U.S. (1925)

A Supreme Court decision holding that a warrantless search of a private dwelling is unreasonable and abhorrent to law, and that a search incident to arrest cannot be extended to a defendant's off-site residence.

California v. Carney (1985)

A Supreme Court decision establishing that the vehicle exception applies to a motor home parked in a public lot because it is readily mobile and situated in a manner objectively indicating transportation use, which affords it a reduced expectation of privacy compared to a fixed dwelling.

Carroll v. U.S. (1925)

The foundational case establishing the automobile exception, holding that a warrantless search of an automobile for contraband is lawful when officers have probable cause and it is impracticable to secure a warrant due to the vehicle's ready mobility.

Carroll Doctrine (Automobile Exception)

A warrant requirement exception allowing law enforcement with probable cause to search any vehicle capable of mobility, and to inspect any container within it where the object of the search could logically be concealed, without obtaining a search warrant.

Chambers v. Maroney (1970)

A Supreme Court ruling holding that where police have probable cause to search a car at the time and place of an arrest, conducting a warrantless search of that vehicle later at the police station does not violate the Fourth Amendment.

Coolidge v. New Hampshire (1971)

A Supreme Court decision invalidating a search warrant issued by a state attorney general acting as a justice of the peace for lack of a neutral and detached magistrate, and holding that the automobile exception does not apply to a non-fleeing vehicle parked in a private driveway absent exigent circumstances.

Plain View Doctrine

A rule permitting law enforcement to seize evidence without a warrant when the initial intrusion bringing the officer into view of the object is justified by a recognized warrant exception, and the incriminating nature of the object is inadvertently discovered.

Florida v. Jardines (2013)

A Supreme Court ruling holding that deploying a trained police dog on the front porch of a home to investigate for contraband constitutes an unlicensed physical intrusion into the curtilage, amounting to a Fourth Amendment search.

Texas v. Brown (1979)

A Supreme Court ruling holding that stopping an individual and demanding identification under a state statute without any reasonable suspicion of criminal misconduct violates the Fourth Amendment.

Curtilage

The enclosed ground and outbuildings immediately surrounding and associated with a home, treated under the Fourth Amendment as part of the home itself due to heightened expectations of domestic privacy.

Dunn Curtilage Factors

The four analytical factors outlined in United States v. Dunn (1987) to evaluate curtilage: proximity to the home, whether the area is within an enclosure surrounding the home, the nature of uses for the area, and steps taken to shield it from public observation.

Castle Doctrine

A common-law principle rooted in English law establishing that a person's dwelling is their castle and immune from arbitrary governmental intrusion, serving as the philosophical foundation for core Fourth Amendment home protections.

Ready Mobility

A foundational justification of the automobile exception denoting that a vehicle is capable of movement (such as by the turn of an ignition key), creating inherent risk that contraband or evidence could quickly be moved beyond judicial reach.

Pervasive Regulation Rationale

A justification supporting the automobile exception based on the reduced expectation of privacy in motor vehicles resulting from continuous governmental regulations, license mandates, safety inspections, and operations on public highways.

Exigent Circumstances Doctrine

An exception to the warrant requirement that allows warrantless searches and entries when emergency conditions exist, such as hot pursuit of a fleeing felon or the imminent destruction of evidence.
