You commit a minor traffic offense, keep driving, and pull into your own garage — and the officer walks in behind you. No warrant. Lange v. California is the Supreme Court’s modern answer.
What did Lange v. California decide?
Pursuit of a fleeing misdemeanor suspect does not, by itself, justify warrantless entry into a home. There is no categorical misdemeanor-pursuit exigency: entry requires a genuine, case-specific emergency — imminent harm, imminent destruction of evidence, or a true escape risk — assessed on the totality.
Lange v. California, 594 U.S. 295 (2021) — read the opinion on CourtListener.
What does Lange v. California allow?
- Warrantless entry when flight is paired with a real, articulable emergency on the facts of the case
What does it NOT allow?
- Flight from a minor offense alone does not open the door
- No emergency means contain the scene and get a warrant
- The home keeps the strongest Fourth Amendment protection — thresholds matter
How it plays out on the street
Lange forces the question every pursuing officer must answer at the doorway: what exactly is the emergency, in this case, right now? Document it — ‘he ran’ is not enough on its own.
Frequently asked questions
Can police always follow someone into a house during a chase?
No. For misdemeanors, Lange requires a genuine case-specific emergency — flight alone doesn’t justify warrantless home entry.
What counts as an emergency under Lange?
Imminent injury to someone, imminent destruction of evidence, or a genuine risk of escape — judged on the specific facts.
What should officers do without an emergency?
Set a perimeter, contain the scene, and get a warrant.
