Is a prison official entitled to qualified immunity in a civil case?

Adesanya contends that the district court erred by finding that prison officials were entitled to qualified immunity on his Eighth Amendment claim and on his due process claims. This contention lacks merit. Under the doctrine of qualified immunity, government officials are shielded from liability for civil damages if their conduct does not violate "clearly established statutory or constitutional rights of which a reasonable person would have known." Harlow v. Fitzgerald, 457 U.S. 800, 818 (1982); see also Act Up!/ Portland v. Bagley, 988 F.2d 868, 871 (9th Cir.1993).
