Section 1983 — Suing for a Violation of Your Rights

Constitutional rights would mean little if there were no way to enforce them against the officials who break them. Section 1983 — passed in 1871 and still on the books — is that tool. It lets you sue a state or local official, including a police officer, who violates your federal constitutional rights.

The key phrase is “under color of law.” The official has to be using government authority when the violation happens. In Monroe v. Pape (1961), the Supreme Court made clear this covers an officer who misuses that power, even if what they did also broke state law.

Section 1983 can reach more than individuals. Under Monell v. Department of Social Services (1978), a city or county itself can be liable when an official policy or custom causes the violation — though not simply because it employed the person who did it.

There is a major limit worth knowing: qualified immunity. This doctrine shields officials from many Section 1983 suits unless they violated a right that was “clearly established” at the time. It is one of the most debated rules in civil-rights law, and it often decides whether a case can move forward at all.
