Tracy Miller Arnold v. City of Guntown; Andrew Stuart

No. 1:25-CV-24-GHD-DAS · United States District Court for the Northern District of Mississippi, Aberdeen Division · February 2, 2026 · No. No. 1:25-CV-24-GHD-DAS

Summary

The United States District Court for the Northern District of Mississippi granted the defendants’ motion for judgment on the pleadings and dismissed Tracy Miller Arnold’s claims under 42 U.S.C. § 1983. The court held that City Prosecutor Andrew Stuart was entitled to absolute prosecutorial immunity in his individual capacity and that Arnold failed to plead a municipal policy or custom supporting liability against the City of Guntown or Stuart in his official capacity. The court also overruled Arnold’s objections to the magistrate judge’s denial of her motion to strike the defendants’ affirmative defenses and denied her motion for partial summary judgment.

Holdings

  1. Andrew Stuart was entitled to absolute prosecutorial immunity because the conduct alleged arose from his advocacy and representation of the City in judicial and appellate proceedings and was intimately associated with the judicial phase of the criminal process.
  2. Arnold failed to state a municipal-liability claim against the City of Guntown or Stuart in his official capacity because she did not adequately allege an official policy or custom, a policymaker's actual or constructive knowledge, and a constitutional violation caused by that policy or custom.
  3. Arnold did not adequately plead the single-incident exception to municipal liability because she did not establish that Stuart was a final policymaker under Mississippi law.
  4. Negligence is not a basis for municipal liability under 42 U.S.C. § 1983, and the City is not vicariously liable for Stuart's alleged negligence.
  5. The magistrate judge's order denying Arnold's motion to strike defendants' affirmative defenses was not clearly erroneous or contrary to law and was properly affirmed. Defendants were required only to provide fair notice and adequately stated their affirmative defenses without detailed factual allegations.

Questions Presented

  1. Whether the City Prosecutor was entitled to absolute prosecutorial immunity from Arnold's individual-capacity claims based on his representation of the City in county-court proceedings and related conduct.
  2. Whether Arnold adequately pleaded municipal liability against the City of Guntown or against Stuart in his official capacity under Monell and its progeny.
  3. Whether the complaint adequately invoked the single-incident theory of municipal liability by alleging that Stuart was a final policymaker.
  4. Whether the magistrate judge's order denying Arnold's motion to strike defendants' affirmative defenses was clearly erroneous or contrary to law.
  5. Whether defendants were entitled to judgment on the pleadings and whether Arnold was entitled to partial summary judgment.
