Jonathon Douglas Mattix v. Allen County Sherriff Dept.

Mattix · United States District Court for the Northern District of Indiana, Fort Wayne Division · December 4, 2025 · No. 1:25-CV-489-HAB-ALT

Summary

The United States District Court for the Northern District of Indiana dismissed Jonathon Douglas Mattix’s prisoner complaint seeking suppression of evidence in his pending or recently adjudicated Indiana criminal case. The court held that abstention principles and 28 U.S.C. § 1915A barred the requested relief because the federal action sought interference with state criminal proceedings and was frivolous.

Holdings

  1. A federal court must abstain from interfering with state criminal proceedings when the plaintiff seeks a favorable federal constitutional ruling that could affirmatively shape or change the direction of those proceedings.
  2. A prisoner complaint seeking unavailable relief and asking a federal court to suppress evidence in a state criminal trial may be dismissed as frivolous under 28 U.S.C. § 1915A.

Questions Presented

  1. Whether a federal court may grant a state criminal defendant's request to suppress evidence for use in an ongoing or unresolved state criminal prosecution.
  2. Whether the complaint was frivolous and subject to dismissal under 28 U.S.C. § 1915A.
