Carrasco v. Atencio

Issues: (1) Whether the U.S. Court of Appeals for the 9th Circuit violated the precept of 42 U.S.C. § 1983, and unlawfully expanded the reach of 42 U.S.C. § 1983, by declaring that the petitioner detention officers, who are not alleged to have either inflicted any constitutional injury or caused others to do so, can nevertheless face 42 U.S.C. § 1983 liability as “integral participants” in others’ allegedly unconstitutional acts; and (2) whether the lower courts’ formulation of the right at issue—“the right to be free from an ‘unprovoked and unjustified attack by a prison guard’”—violates the Supreme Court's directive that to be clearly established, the “right at issue” for purposes of a qualified immunity analysis must be particularized to the facts of the case.
