August Wakat v. Henry Winn; Linda Winn; John Does 4–50

Wakat · United States District Court for the Northern District of Oklahoma · February 9, 2026 · No. 25-CV-00380-SEH-JFJ

Summary

The United States District Court for the Northern District of Oklahoma dismisses August Wakat’s pro se complaint without prejudice for failure to adequately plead subject-matter jurisdiction. The court concludes that the complaint’s diversity-jurisdiction allegations identify residence rather than citizenship and do not establish the citizenship of the defendants; related motions are deemed moot.

Holdings

  1. Allegations that parties reside in particular states are insufficient to establish citizenship for diversity jurisdiction; citizenship depends on domicile.
  2. A federal court must dismiss a claim that does not fall within its subject-matter jurisdiction, including when the jurisdictional defect is identified sua sponte.

Questions Presented

  1. Whether the complaint adequately alleged facts establishing diversity subject-matter jurisdiction under 28 U.S.C. § 1332(a)(1).
  2. Whether the court was required to dismiss the complaint sua sponte when the record did not establish subject-matter jurisdiction.

Disposition

dismissed
