558 F.3d 614
7th Cir.
2009
PER CURIAM.

Defendants removed this suit from state to federal court, asserting that jurisdiction is proper under 28 U.S.C. § 1332. The district judge remanded it after concluding that the allegations do not establish complete diversity of citizenship. Defendants have appealed, and plaintiffs have confessed error (apparently they, too, now want to be in federal court), but we lack appellate jurisdiction.

A case remanded to state court is not reviewable, by appeal or otherwise, unless one of a few exceptions applies. 28 U.S.C. § 1447(d). See Thermtron Products, Inc. v. Hermansdorfer, 423 U.S. 336, 96 S.Ct. 584, 46 L.Ed.2d 542 (1976). These litigants contend that their case is exceptional because the district court remanded because of a defect in removal procedure, something that may be done only on motion within 30 days of removal, see 28 U.S.C. § 1447(c), while this remand occurred sua sponte and some 90 days after removal. But the district court said that it was remanding for lack of subject-matter jurisdiction, a step proper at any time.

The district judge observed that the notice of removal alleged the parties’ “residence,” while jurisdiction depends on their citizenship, which is to say their domicile. Gilbert v. David, 235 U.S. 561, 35 S.Ct. 164, 59 L.Ed. 360 (1915). This is not, as the parties would have it, a “defect in removal procedure.” It is a genuine jurisdictional problem. E.g., Steigleder v. McQuesten, 198 U.S. 141, 25 S.Ct. 616, 49 L.Ed. 986 (1905); Denny v. Pironi, 141 U.S. 121, 11 S.Ct. 966, 35 L.Ed. 657 (1891); Robertson v. Cease, 97 U.S. 646, 24 L.Ed. 1057 (1878). Perhaps the judge should have allowed the parties to amend their jurisdictional allegations, but the fact remains that the remand was for lack of subject-matter jurisdiction. That a jurisdictional remand may have been erroneous does not make it appealable. Powerex Corp. v. Reliant Energy Services, Inc., 551 U.S. 224, 127 S.Ct. 2411, 168 L.Ed.2d 112 (2007); Kircher v. Putnam Funds Trust, 547 U.S. 633, 126 S.Ct. 2145, 165 L.Ed.2d 92 (2006); Gravitt v. Southwestern Bell Telephone Co., 430 U.S. 723, 97 S.Ct. 1439, 52 L.Ed.2d 1 (1977).

The appeal is dismissed for want of jurisdiction.
