- What it's about
This case asked whether a police officer could be sued for excessive force after he briefly put his knee on the back of a suspect who had a knife in his pocket while officers were disarming and handcuffing him during a domestic violence response. The Supreme Court held that the officer was entitled to qualified immunity because prior cases had not clearly established that this conduct was unconstitutional.
Question presented
1. Did the Ninth Circuit depart from this Court’s decisions in Graham v. Connor, 490 U.S. 386 (1989) and Plumhoff v. Rickard, 572 U.S. 765 (2014) in denying qualified immunity to petitioner based upon the absence of a constitutional violation, by concluding that pushing a suspect down with a foot and briefly placing a knee against the back of a prone, armed suspect while handcuffing him, could constitute excessive force? 2. Did the Ninth Circuit depart from this Court’s decision in Kisela v. Hughes, ___ U.S. ___, 138 S. Ct. 1148 (2018) (per curiam) and numerous other cases by denying qualified immunity even though two judges concluded the use of force was reasonable, and notwithstanding the absence of clearly established law imposing liability under circumstances closely analogous to those confronting petitioner?
