42 U.S.C. § 1983
Section 1983: suing a state or local official for violating your federal rights
A federal claim in United States district courts · Last verified August 26, 2026
Section 1983 is the most-filed claim in the federal courts, and it is not a claim at all. It creates no rights. It is a vehicle — a way to sue in federal court over a right that lives somewhere else, in the Constitution or in another federal statute.
That distinction explains most of what follows. The elements are short because the hard work happens in the underlying right. The deadline comes from state law because Congress never wrote one. And the defense that ends most of these cases, qualified immunity, appears nowhere in the statute.
What the claim is
Someone acting for a state or local government violated a federal right, and you want damages or an injunction. Police officers are the most common defendants: excessive force, arrest without probable cause, unlawful search. Prison and jail officials are the next most common, sued over medical care and conditions of confinement. After that come school officials, licensing boards, child-welfare workers, and city councils.
The defendant has to be a state or local actor. Federal officers are not covered — a suit against them runs on a different and much narrower track.
Where the right comes from
Congress wrote the private right of action into the statute itself:
Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory or the District of Columbia, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress.
Read the last four words of the rights clause again: "the Constitution and laws." Most § 1983 cases enforce a constitutional right, and there the path is clear. Enforcing an ordinary federal statute through § 1983 is harder. The statute you point to has to confer an individual right in unambiguous terms — a benefit to the public, or a general directive to a state agency, is not enough. The Supreme Court tightened that test in Gonzaga University v. Doe and confirmed in Health and Hospital Corp. of Marion County v. Talevski that a statute passed under the Spending Clause can still clear it.
What a plaintiff has to prove
The core elements are two, and courts state them in a form close to this:
- A person acting under color of state law
- deprived the plaintiff of a right secured by the Constitution or federal law.
Sue a city or county and there is a third element, which is where these cases go to die. A municipality is not liable because it employs the officer who hurt you. It is liable only when its own policy or custom caused the violation — a written policy, a practice so settled it amounts to one, a decision by someone with final policymaking authority, or a failure to train that rises to deliberate indifference. That rule comes from Monell v. Department of Social Services, and it is why so many complaints name the officer and the city and end up with only the officer.
No heightened pleading applies. Ordinary notice pleading governs, and the Supreme Court said so directly in Leatherman v. Tarrant County Narcotics Intelligence and Coordination Unit — a municipal liability claim does not have to be pleaded with particularity.
How long you have to file
There is no federal deadline. Section 1983 contains none, so federal courts borrow one, and the borrowed period is the forum state's limitations period for personal injury. Where a state has several, courts take the general or residual personal-injury period rather than a specific intentional-tort period. In practice that means one to six years depending on where you sue.
Then comes the part people miss. State law supplies the length; federal law decides when the clock starts. A § 1983 claim accrues when the plaintiff knows or has reason to know of the injury. Two wrinkles matter:
- A claim that would necessarily imply your criminal conviction was invalid does not accrue at all until that conviction is overturned. That is the Heck v. Humphrey bar, and it is a trap and a shield at once.
- A fabricated-evidence claim accrues when the criminal case ends in the defendant's favor, not when the evidence was fabricated.
Tolling is generally borrowed from state law too, unless a state rule would defeat the statute's purpose.
What has to happen before you file
For most plaintiffs, nothing. There is no charge to file, no agency to notify, no waiting period. State notice-of-claim statutes — the ones that require you to tell a city you intend to sue within 90 days — do not apply to a § 1983 claim, in state or federal court.
There is one large exception. A prisoner suing over prison conditions must first exhaust the prison's own grievance process. That requirement is real and it is enforced. But it is an affirmative defense, not something the plaintiff has to plead or prove: the defendant has to raise non-exhaustion and carry it.
Who can be sued — and who cannot
Individual officials — yes, in their personal capacity, and this is where damages come from.
Cities, counties, and other local governments — yes, subject to the policy-or-custom rule.
States and state agencies — no. A state is not a "person" under § 1983 and cannot be sued for damages. Neither can a state official sued in an official capacity, which is the same suit wearing a different hat.
The workaround is old and narrow: you may sue a state official in an official capacity for prospective injunctive relief to stop an ongoing violation. Damages for past harm stay off the table.
Private parties are not liable unless their conduct is fairly attributable to the state.
Common defenses
Qualified immunity ends more § 1983 cases than every other defense combined. An individual official is immune from damages unless the right was clearly established at the time — meaning existing law had placed the question beyond debate. The defendant raises it; it can be decided before discovery; and an order denying it can be appealed immediately, which is unusual and expensive for plaintiffs.
Absolute immunity protects a narrower set of actors completely: judges for judicial acts, prosecutors for advocacy, legislators for legislative acts, and witnesses for their testimony.
The Heck bar blocks damages claims that would imply a standing conviction is invalid.
No state action, no constitutional violation, no causation — the ordinary merits defenses.
What the claim pays
Compensatory damages, with no statutory cap. Nominal damages where a right was violated but no actual injury resulted. Punitive damages against individuals whose conduct was reckless or callously indifferent — but never against a municipality.
Injunctive and declaratory relief are available and are the point of many of these cases.
Attorney's fees go to a prevailing party under a companion statute, 42 U.S.C. § 1988. The two directions are not symmetrical: a winning plaintiff normally recovers fees, while a winning defendant recovers only if the suit was frivolous, unreasonable, or groundless. A judgment for nominal damages alone can support a fee award of nothing.
What people get wrong
"I can sue the state." No. A state is not a person under this statute.
"The city is on the hook because its officer did it." No. Section 1983 rejects vicarious liability outright. You need a policy, a custom, or a training failure amounting to deliberate indifference.
"There's a federal statute of limitations." No. Look to the forum state's personal-injury period — and then apply federal accrual rules to decide when it started.
"Any federal statute can be enforced through § 1983." No. The statute has to create an individual right in unambiguous terms.
"Section 1983 cases have to be in federal court." No. State courts have jurisdiction over § 1983 claims too.
"Qualified immunity needs a case with identical facts." Not identical — but close enough that existing law put the question beyond debate.
Where it came from
Section 1983 began as section 1 of the Civil Rights Act of 1871, passed to give freedpeople a federal forum when Southern states would not protect them. It then did almost nothing for ninety years. Monroe v. Pape in 1961 revived it by holding that an official who breaks state law is still acting under color of it — after which filings climbed and never stopped.
The two decisions that shaped what the statute is today came later: Monell in 1978, opening municipal liability and immediately narrowing it, and Harlow v. Fitzgerald in 1982, giving qualified immunity the objective form courts still apply.
Common questions
Is there a deadline to file a section 1983 claim?
Yes, but it is not in the statute. Federal courts borrow the forum state's limitations period for personal injury, which runs from one to six years depending on the state. Federal law decides when that clock starts — generally when you knew or should have known of the injury.
Can I sue a police officer personally under section 1983?
Yes. Individual-capacity claims against officers are the ordinary way these suits are brought, and they are where damages come from. The officer will almost certainly raise qualified immunity.
Can I sue the city that employs the officer?
Only if the city itself caused the violation through a policy, a custom, or a failure to train amounting to deliberate indifference. Employing the officer is not enough.
Do I have to file a complaint with an agency first?
No. Section 1983 has no administrative exhaustion requirement, and state notice-of-claim statutes do not apply to it. Prisoners suing over prison conditions are the exception — they must exhaust the prison grievance process first.
Does section 1983 apply to federal officers?
No. It reaches only those acting under color of state law. Claims against federal officers proceed on a separate and considerably narrower footing.
