Whether federal courts may require plaintiffs asserting municipal liability under 42 U.S.C. § 1983 to satisfy a pleading standard more demanding than Federal Rule of Civil Procedure 8(a).
Holding
No. A § 1983 claim against a municipality is governed by Rule 8(a)'s ordinary notice-pleading standard, not a judicially created heightened pleading requirement.
Reasoning
Rule 8(a)(2) requires only a short and plain statement showing that the pleader is entitled to relief. Under Conley v. Gibson, a complaint need not set out detailed facts; it need only give the defendant fair notice of the claim and the grounds on which it rests.
The Fifth Circuit's rule expressly demanded factual detail and particularity beyond ordinary pleading requirements. Although respondents characterized the rule as merely applying Rule 8 in light of the substantive complexity of municipal liability, the court of appeals had adopted and applied it as a distinct, more demanding rule for § 1983 litigation.
The Federal Rules themselves identify the limited circumstances in which greater factual particularity is required. Rule 9(b) requires particularity for allegations of fraud or mistake, but it does not include § 1983 claims alleging municipal liability. The Court applied the negative implication of that deliberate omission: courts may not add a new category of particularized pleading by interpretation.
If municipal-liability claims should receive special pleading treatment, that change must come through the formal process for amending the Federal Rules, not through a court-created exception. Until then, district courts must use discovery management and summary judgment to dispose of unmeritorious claims.
