Warrantless home entry
Lange v. California
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.
Summary: written with AI from the case record.

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.
