Arizona v. Gant
The Supreme Court ruled that police may not automatically search a car just because its driver was arrested. Officers can search the vehicle only if the arrestee could still reach it at the time of the search, or if it's reasonable to think the car holds evidence of the crime he was arrested for.
The decision narrows a rule from a 1981 case that many courts had treated as giving police free rein to search any car after any arrest of its occupant, even once the person was safely handcuffed and secured away from the vehicle.
How it got here: An Arizona trial court denied Gant's motion to suppress and he was convicted; the Arizona Supreme Court reversed, and the State asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Rodney Gant was arrested outside a house on an outstanding warrant for driving with a suspended license. After he was handcuffed and locked in a patrol car, officers searched his car and found a gun and cocaine in a jacket pocket on the backseat. Gant was convicted of drug charges based on that evidence, which he argued was obtained through an unconstitutional search.
The question before the Court
After police handcuffed a man and locked him in a patrol car, could they still search his car as part of the arrest?
The Court's answer
No — once Gant was handcuffed and locked in the back of a patrol car, officers could no longer search his car simply because he had recently been arrested. The Court held that police may search a vehicle incident to a recent occupant's arrest only if the arrestee could still reach into the passenger compartment at the time of the search, or if it's reasonable to believe the vehicle contains evidence of the crime the person was arrested for.
Neither condition was met here: five officers had already secured Gant and two other suspects in separate patrol cars, so he had no way to reach his car, and he had been arrested only for driving with a suspended license, a offense that wouldn't leave evidence in the vehicle. Because neither justification applied, the search was unreasonable and the drugs found in the car should have been suppressed.

Why it matters
Millions of routine traffic and other arrests happen every year, and this ruling limits when police can search the arrestee's car afterward without a warrant. People stopped for minor offenses like driving with a suspended license gain more protection against car searches, while officers retain search authority when there's a real safety or evidence reason.
What changes now
This is a final merits ruling, not a temporary order. The Arizona Supreme Court's decision suppressing the evidence stands, and going forward officers nationwide must limit car searches following an arrest to situations where the arrestee could still reach the vehicle or where there is a reasonable basis to believe it holds evidence of the arrest offense. Cases already relying on the old broad practice may be affected by the narrower rule.
What this does not decide
The Court did not decide how its new rule applies when only some occupants of a car are arrested and others remain free to access it, or when a non-occupant bystander might try to retrieve a weapon or evidence from the car while officers are still present. Justice Alito's dissent specifically flagged these unresolved scenarios.
Concurrences and dissents
Concurrence — Justice Scalia
Justice Scalia argued the officer-safety rationale for car searches incident to arrest is basically a fiction and would have preferred to allow such searches only when officers are looking for evidence of the crime of arrest or another crime with probable cause. He nonetheless joined the majority's opinion to avoid a fractured decision, calling the alternative of leaving Belton's broad reading intact the greater evil.
Dissent — Justice Breyer
Justice Breyer agreed the Belton rule can produce results disconnected from its Fourth Amendment justification, but concluded that stare decisis and substantial reliance by law enforcement on the existing rule outweighed the case for changing it. He joined Justice Alito's dissent except for the part reexamining Chimel's own reasoning.
Dissent — Justice Alito
Justice Alito argued the majority effectively overruled Belton and Thornton without being asked to, replacing a clear, workable bright-line rule with a confusing two-part test. He emphasized heavy police reliance on the old rule, contended the new rule reintroduces unpredictable case-by-case judgments, and argued the majority's criticism of Belton's reasoning actually calls Chimel itself into question.
How the Court got there
The legal reasoning, step by step
- The Court started from the general rule that warrantless searches are presumptively unreasonable under the Fourth Amendment unless they fit a specific, well-defined exception, and it examined the search-incident-to-arrest exception first recognized in Chimel v. California.
- Under Chimel, that exception lets officers search only the area within an arrestee's immediate control -- the space from which he might grab a weapon or destroy evidence -- because the exception exists solely to protect officer safety and preserve evidence.
- The Court explained that a 1981 case, New York v. Belton, applied this same reasoning to cars, assuming that the passenger compartment is generally within an arrestee's reach, but many lower courts had stretched that assumption into a blanket rule allowing car searches even when the arrestee was handcuffed and locked away from the vehicle.
- Because that blanket practice no longer served the safety and evidence-preservation reasons that justified the exception in the first place, the Court held that a car search incident to arrest is only justified when the arrestee is actually within reaching distance of the vehicle at the time of the search.
- The Court then recognized a second, independent basis for such a search: officers may search the vehicle when it is reasonable to believe it contains evidence connected to the specific crime for which the person was arrested.
- Applying both parts of this test to Gant's arrest, the Court found neither justification present -- five officers had already secured Gant and two other suspects in separate patrol cars, and his arrest was for a suspended license, an offense unlikely to have left evidence inside the car.
