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

Government officials are entitled to qualified immunity "to shield them from undue interference with their duties and from potentially disabling threats of liability." Harlow v. Fitzgerald, 457 U.S. 800, 806 (1982) (Harlow ). This qualified immunity shields government officials "from liability for civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known." Id. at 818, citing Procunier v. Navarette, 434 U.S. 555, 565 (1978).
