Warrantless home entry

Lange v. California

Updated Sep 19, 2026

In brief

The Court said a misdemeanor chase alone is not enough to enter a home without a warrant, then wiped out the lower court’s ruling and sent the case back to that court (vacated and remanded).

Where it stands
Decided

Decided 9-0 · June 23, 2021 · Opinion by Justice Kagan

What it’s about
This case asked whether a police officer may enter a home or attached garage without a warrant while chasing someone suspected of a misdemeanor.
Who it affects
Police and lower courts cannot treat every misdemeanor chase as automatic permission to enter a home. They must examine the specific facts to decide whether an emergency justified entry without a warrant.

What it's about

The Supreme Court held that chasing a fleeing misdemeanant does not automatically create an emergency under the Fourth Amendment; courts must look at the specific facts of each case.

The case concerns the Fourth Amendment’s broader protection for homes and its emergency exception to the usual warrant requirement.

Question presented

Does pursuit of a person who a police officer has probable cause to believe has committed a misdemeanor categorically qualify as an exigent circumstance sufficient to allow the officer to enter a home without a warrant?

What the Court decided

Holding

Under the Fourth Amendment, pursuit of a fleeing misdemeanor suspect does not always—that is, categorically—justify a warrantless entry into a home. Vacated and remanded.
