Can a plaintiff bring a claim under Section 1983 of the Constitution for constitutional violations?

To state a claim pursuant to Section 1983, the vehicle for bringing a claim for constitutional violations, a plaintiff must plead facts indicating that the defendants acted under color of state law at the time the act complained of was committed and that the defendants deprived the plaintiff of the rights, privileges, or immunities secured by the Constitution or laws of the United States. Gibson v. United States, 781 F.2d 1334, 1338 (9th Cir. 1986). Generally, private parties are not acting under color of state law, and their conduct does not constitute state action. See Price v. Hawaii, 939 F.2d 702, 707-08 (9th Cir.1991).
