Case v. Montana

AI-Generated Summary

Case Name: William Trevor Case, Petitioner v. Montana
Docket Number: No. 24–624
Dates: Argued October 15, 2025—Decided January 14, 2026
Lower Court: Supreme Court of Montana (certiorari granted from 417 Mont. 354, 553 P. 3d 985 (2024))

Petitioner William Case called his ex-girlfriend J.H., threatening suicide while sounding erratic and possibly intoxicated; she heard a clicking sound like cocking a gun, a "pop," and then silence, leading her to call 911 fearing he had shot himself.
Officers arrived for a welfare check, aware of Case's history of mental health issues, alcohol abuse, prior suicide threats, and a possible prior "suicide-by-cop" attempt; they observed empty beer cans, an empty handgun holster, and a notepad (suspected suicide note) through windows, with no response to knocking.
Officers entered without a warrant to render aid; Case emerged from hiding holding a gun-like object, prompting an officer to shoot him in self-defense; a handgun was later found nearby, and Case was hospitalized.
Procedural History: Case moved to suppress evidence from the entry as a Fourth Amendment violation; trial court denied, jury convicted him of assaulting an officer; Montana Supreme Court affirmed under its "community caretaker doctrine" requiring "objective, specific and articulable facts" to suspect peril, rejecting probable cause; U.S. Supreme Court granted certiorari to resolve circuit split on probable cause for emergency aid entries.

Whether the Fourth Amendment's emergency aid exception to the warrant requirement for home entries, as stated in Brigham City v. Stuart, 547 U. S. 398 (2006), requires probable cause (as petitioner argued) or merely an "objectively reasonable basis for believing" an occupant needs aid.
Involves interpretation of the Fourth Amendment (prohibiting unreasonable searches/seizures, with warrant presumption for homes subject to exceptions).
Parties' Arguments: Petitioner urged probable cause due to home's sanctity, equating emergency risk to criminal activity; Montana Supreme Court applied caretaker doctrine (facts for "suspect[ion]" of peril, akin to reasonable suspicion); State and U.S. (amicus) defended Brigham City's reasonableness standard, distinct from probable cause or suspicion.

Author & Type: KAGAN, J., for a unanimous Court.
Holding: Brigham City's "objectively reasonable basis for believing" standard governs warrantless home entries for emergency aid, without requiring probable cause (rooted in criminal investigations) or resembling reasonable suspicion; standard satisfied here based on ex-girlfriend's report, Case's history, and scene observations suggesting possible self-inflicted injury or imminent suicide.
Legal Reasoning: Warrantless home entries presumptively unreasonable but excepted for emergencies (Brigham City, Michigan v. Fisher, Caniglia v. Strom); rejected Montana's "community caretaker" framing (post-Caniglia) and its test evoking Terry reasonable suspicion; probable cause "peculiarly related to criminal investigations" (Treasury Employees v. Von Raab) unfit for non-investigatory aid; assessed on totality of circumstances, limited to needs of emergency/officer safety; officers' 40-minute delay and precautions reflected balanced judgment, not creating danger.
Disposition: Affirmed judgment of Montana Supreme Court (not all reasoning).

SOTOMAYOR, J.: Joined majority but emphasized mental-health crisis nuances; entry not always reasonable (risk of escalation, esp. with firearms/history); urged de-escalation (e.g., phone contact, crisis teams, professionals) before entry; facts here (phone "pop," holster, note) supported reasonableness despite suicide-by-cop risks.
GORSUCH, J.: Joined majority; rooted exception in common-law history allowing private citizens/officers to enter for serious harm prevention if reasonably necessary (e.g., Restatement (Second) of Torts §197), limited to emergency; critiqued Katz-era "reasonable expectations" for ignoring historical "constitutional doctrine."

Reaffirms/clarifies emergency aid exception as "objectively reasonable basis" standard from Brigham City (not probable cause or reasonable suspicion), resolving circuit split; limits entries to emergency necessities/officer safety, without broader "caretaker" license (Caniglia); stresses totality of circumstances, esp. suicide/mental health risks; underscores home's "first among equals" status while enabling life-saving aid.
