What it's about

The Supreme Court ruled the officers were protected by qualified immunity (protection from civil damages unless officials violate a clearly established legal right) and overturned the Ninth Circuit’s ruling against them.

The warrant followed allegations that Jerry Bowen, described as a gang member and felon, used a sawed-off shotgun to attack his former girlfriend. Augusta Millender’s estate challenged the search of her home.

Qualified immunity can shield government officials from civil damages unless they violate a clearly established legal right.

Question presented

Are police officers entitled to qualified immunity when they obtain a valid warrant to search for firearms, firearm-related materials, and gang-related items in the residence of a gang member and felon who had threatened to kill his girlfriend and fired a sawed-off shotgun at her?

What the Court decided

Holding

The officers are entitled to qualified immunity. Pp. 8 − 19. 620 F. 3d 1016, reversed.
