In Allen v. McCurry, 449 U.S. 90 (1980), the Supreme Court held that a federal court hearing a civil rights suit under 42 U.S.C. § 1983 must give preclusive effect to a Fourth Amendment ruling already made against the plaintiff in a state criminal case, provided the plaintiff had a full and fair opportunity to litigate the issue there.1Legal Information Institute. Allen v. McCurry, 449 U.S. 90 (1980) – Section: Syllabus In practical terms, a defendant who loses a suppression motion in state court usually cannot turn around and sue the officers in federal court to relitigate whether the search was lawful.
How the Case Reached the Supreme Court
Undercover officers went to Willie McCurry’s home to attempt a heroin buy. A gun battle broke out, two officers were wounded, and officers then entered the house without a warrant and seized drugs and other evidence. Charged with heroin possession and assault with intent to kill, McCurry moved to suppress the evidence as the product of an unreasonable search.1Legal Information Institute. Allen v. McCurry, 449 U.S. 90 (1980) – Section: Syllabus
The state trial court held a suppression hearing and granted the motion only in part, allowing items found in plain view to come in while excluding others. McCurry was convicted, and the ruling was upheld on appeal. He then sued the officers in federal court under 42 U.S.C. § 1983, seeking damages for the same alleged Fourth Amendment violation the state judge had already rejected.1Legal Information Institute. Allen v. McCurry, 449 U.S. 90 (1980) – Section: Syllabus Section 1983 lets a person sue anyone who, acting under state authority, deprives them of a federal right.2Office of the Law Revision Counsel. 42 U.S.C. § 1983
What the Supreme Court Held
The Court ruled that ordinary rules of collateral estoppel, also called issue preclusion, apply to Section 1983 suits. Once a court decides a specific legal or factual issue, the parties generally cannot relitigate it in a later case. The Court grounded its answer in the Full Faith and Credit Act, 28 U.S.C. § 1738, which requires federal courts to give a state court judgment the same effect it would have in the courts of the state that rendered it.3GovInfo. 28 U.S.C. § 1738
Nothing in Section 1983, the Court found, showed a congressional intent to carve out an exception to that rule. Section 1983 was not written to guarantee civil rights plaintiffs a choice between state and federal forums for the same claim, or to give them a second chance at an issue they had already lost. State courts, the Court emphasized, are competent to decide federal constitutional questions, including Fourth Amendment claims raised on a motion to suppress.1Legal Information Institute. Allen v. McCurry, 449 U.S. 90 (1980) – Section: Syllabus
The Full and Fair Opportunity Requirement
The preclusive effect is not automatic. For a state ruling to bind a federal court in a later Section 1983 case, the plaintiff must have had a full and fair opportunity to litigate the constitutional issue in the state proceeding. If the state process was fundamentally inadequate, or if the state court lacked jurisdiction over the matter, the federal court is not bound by what the state judge decided.1Legal Information Institute.

What Allen v. McCurry Means for a Later Section 1983 Suit
If you litigated a Fourth Amendment claim, or another federal constitutional issue, in a state criminal case and lost, Allen v. McCurry is the reason a federal civil rights suit built on the same issue will usually be blocked. The federal court will look at what the state court decided, whether the same issue is being raised again, and whether you had a real chance to develop and argue it. If those conditions are met, the earlier ruling controls, and the federal case cannot be used to redo the suppression hearing under a different caption.
The narrow opening the decision leaves is the fairness of the state process itself. A claim that the state court refused to hear the issue, denied a hearing, or lacked jurisdiction is the kind of argument that keeps the federal door open. A claim that the state judge simply got it wrong is not.
