Section 1983 and Qualified Immunity Explained: A Claim Checker
Section 1983 of the US Code gives a civil damages claim against a person who, acting under color of state law, deprives another of rights secured by the Constitution and federal law. An individual officer is protected by qualified immunity unless the right was clearly established, meaning that earlier law gave fair warning that the conduct was unlawful, or the violation was obvious. A city or county is liable only for its own policy, custom, or a deliberately indifferent failure to train or supervise (Monell); it is not liable merely for employing the officer, but it cannot claim qualified immunity. States and state agencies are generally not suable for damages under the section, and judges, prosecutors and legislators have absolute immunity for their official functions.
Tool · Section 1983 and Qualified Immunity Checker
A section 1983 damages claim faces a serious obstacle: see the problems marked.
Under color of state law: The defendant used power given by state law, so section 1983 can apply.
Violation of a federal right: A federal right (for example the Fourth Amendment’s protection against excessive force) was violated.
Causation: The violation caused the harm.
Qualified immunity: Qualified immunity shields the officer unless the right was clearly established at the time, with authority on closely similar facts or an obvious violation. The claim against the officer would probably be dismissed even though the right was violated.
- Section 1983 (42 U.S.C.) gives a civil claim against anyone who, under color of state law, deprives a person of rights secured by the Constitution and federal law. It does not apply to federal officers (Bivens claims are narrow and have been restricted) and states have their own claims for police misconduct.
- The doctrine of qualified immunity is controversial and has been criticised and debated; some states have limited it by statute. Check the law of the jurisdiction and circuit.

Common questions
What does clearly established mean?
That existing precedent put the constitutional question beyond debate, usually through controlling authority or a robust consensus of persuasive authority on similar facts, or that the violation was obvious.
Can a city be sued if an officer breaks the rules?
Only if a city policy or custom, a final policymaker’s decision or a deliberately indifferent failure to train or supervise was the moving force of the violation.
Is qualified immunity the same everywhere?
It is a federal doctrine applied in federal claims; some states have limited or removed it for state-law claims. Check the law of the jurisdiction.
