Qualified immunity is a judge-made doctrine in United States federal law that protects state and federal officials—most commonly police officers—from personal liability in civil lawsuits brought under 42 U.S.C. § 1983 or, for federal officers, under Bivens v. Six Unknown Named Agents (1971). An official is immune unless the plaintiff shows two things: (1) the official violated a constitutional or statutory right, and (2) that right was "clearly established" at the time, meaning a reasonable official would have known the conduct was unlawful.
The doctrine originated in Pierson v. Ray (1967), which recognized a good-faith defense for officers, and was reformulated in Harlow v. Fitzgerald (1982) into its current objective test. In Saucier v. Katz (2001), the Supreme Court mandated a sequential two-step analysis, but Pearson v. Callahan (2009) made that order discretionary, allowing courts to dispose of cases on the "clearly established" prong without ruling on the underlying constitutional question.
Critics argue the "clearly established" standard is excessively demanding because it generally requires a prior case with nearly identical facts, producing what scholars call a "Catch-22": rights cannot be clearly established without prior rulings, but courts increasingly avoid making such rulings. Notable applications include Mullenix v. Luna (2015) and Kisela v. Hughes (2018), where the Court reversed denials of immunity to officers who used deadly force.
Reform proposals intensified after the May 2020 killing of George Floyd. The U.S. House passed the George Floyd Justice in Policing Act in 2020 and again in 2021, which would have limited the doctrine, but it stalled in the Senate. Some states have acted independently: Colorado (SB 20-217, 2020) and New Mexico (HB 4, 2021) created state civil rights causes of action that bar qualified immunity as a defense.
The doctrine does not apply to criminal prosecutions, municipal liability under Monell v. Department of Social Services (1978), or claims for injunctive relief.
Example
In *Taylor v. Riojas* (2020), the U.S. Supreme Court denied qualified immunity to Texas prison officials who confined inmate Trent Taylor in feces-covered cells, ruling the conditions were obviously unconstitutional even without a closely analogous prior case.
Frequently asked questions
No. The doctrine applies only to civil damages suits. Officers can still be prosecuted criminally under state law or federal statutes like 18 U.S.C. § 242.
