   ** TEXT ONLY ORDER **
   This is a breach-of-contract case. There are pending summary judgment motions, but before the court can resolve those, two problems related to the court's jurisdiction must be addressed. First, plaintiff Tarsco Bolted Tank, Inc. did not submit evidence establishing that this court has subject-matter jurisdiction under 28 U.S.C. § 1332. Tarsco alleged diverse citizenship in its amended complaint, but at the summary judgment stage, the proponent of jurisdiction must prove jurisdiction with admissible evidence. See Lujan v. Nat'l Wildlife Fed'n, 497 U.S. 871, 888 (1990). Defendants did not admit all of Tarsco's allegations of citizenship in their answers, nor do the pleadings properly allege the citizenship of American Engineered, which is a limited-liability company, so its citizenship is the citizenship of its members. See City of E. St. Louis, Illinois v. Netflix, Inc., 83 F.4th 1066, 1070 (7th Cir. 2023). The court will give Tarsco until September 25 to supplement its summary judgment submissions with admissible evidence of the citizenship of all parties. The court expects defendants to cooperate in the effort to establish citizenship, and the parties may file a stipulation on jurisdiction, so long as the stipulation lays out all the relevant facts about the citizenship of the parties. Prizevoits v. Indiana Bell Telephone Co., 76 F.3d 132, 134 (7th Cir. 1996). If Tarsco does not respond, the case may be dismissed for lack of jurisdiction. Second, Tarsco and intervenor Cincinnati Specialty Underwriters Insurance Company are both citizens of Delaware. The court will give Cincinnati Specialty Underwriters until September 25 to submit a short brief explaining why it should not be dismissed to avoid destroying diversity jurisdiction. Signed by Magistrate Judge Anita Marie Boor on 9/21/2026. (jls)
