April 16, 2025 Filing 6 AMENDED NOTICE OF REMOVAL from Third District Court Salt Lake County, case number 250901948, against All Plaintiffs with Jury Demand. filed by Ciox Health LLC. (Attachments: #1 Exhibit A - State Docket, #2 Exhibit B - Summons and Complaint) (Bledsoe, Jordan)
April 16, 2025 Opinion or Order Filing 5 DOCKET TEXT ORDER. Although Defendant invokes this court's diversity jurisdiction, it has failed adequately to allege the citizenship of Plaintiffs Mary Mayo and Angela Micklos. Defendant alleges in #1 Notice of Removal that Plaintiffs "are both residents of the State of Utah." Id. 8. But it is well settled that for individuals who are United States citizens, diversity jurisdiction turns on state citizenship, not mere residence; that state citizenship turns on domicile; and that domicile is not the same thing as residence. See, e.g., Mississippi Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 48 (1989); Siloam Springs Hotel, L.L.C. v. Century Sur. Co., 781 F.3d 1233, 1238 (10th Cir. 2015); Smith v. Cummings, 445 F.3d 1254, 1259-60 (10th Cir. 2006); Whitelock v. Leatherman, 460 F.2d 507, 514 (10th Cir. 1972). (For a non-U.S. citizen, the court instead looks to the actual country of citizenship.) No later than April 30, 2025, Defendant shall file an amended notice of removal that correctly alleges each Plaintiff's citizenship for purposes of diversity jurisdiction. See 28 U.S.C. 1653. If this submission fails to establish minimal diversity between Defendant and at least one Plaintiff, as required by 28 U.S.C. 1332(d), this action will be remanded to the state court. SO ORDERED. No attached document. Signed by Judge Howard C. Nielson, Jr., on 4/15/2025. (dle)
