  1. Argument 1 ·

    What happened at the argument

    Chief Justice Roberts opened the argument and heard from Fred A. Rowley Jr. for Case. Rowley argued the Court has never allowed home entries without a warrant or probable cause. He said Montana's proposed standard is vague and open-ended. He argued a probable cause standard fits existing Fourth Amendment rules, citing Payton.

    The case was submitted after argument.

    The Court heard argument on the dispute but has not decided it.

How the case got here

Police entered Trevor Case's home without permission, a warrant, or probable cause, and shot him inside. Case argues the Fourth Amendment bars home entries without probable cause that an occupant is seriously injured or imminently threatened. Montana defends the emergency aid exception, which allows entry when officers have an objectively reasonable basis to believe someone inside needs aid.

What each side wants

Case wants the Court to require probable cause of a danger before any warrantless emergency home entry.

Montana wants the Court to keep the objective reasonableness standard from Brigham City v. Stuart, which does not require probable cause of a danger.

What each side says

Case says the home's sanctity is the core of the Fourth Amendment and that a lower standard invites abuse, letting police back into criminal investigations without a warrant.

Montana says the Fourth Amendment's text ties probable cause to warrants, not searches. And That a probable cause rule would delay officers from saving lives in crises like domestic violence or falls.

What the justices asked

Chief Justice Roberts asked why the standard should not be reasonable concern rather than probable cause, and whether officers must diagnose a medical emergency before entering.

Justice Alito asked what more officers needed than an ex-girlfriend's report of a suicide threat, a gunshot-like sound, a dead phone line, an empty holster. And An apparent suicide note visible through a window.

Why it matters

The ruling will set the threshold police must meet before entering a home without a warrant to give emergency aid. It will shape responses to suicide threats, medical crises, and domestic violence calls nationwide.

What the Court decided

Police may enter a home without a warrant if they have an objectively reasonable basis for believing someone inside needs emergency aid. The officers here had such a basis for entering Case's home to prevent him from killing himself.
