CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE FEDERAL CIRCUIT
No. 07–1437. Argued February 24, 2009—Decided May 4, 2009
Respondents filed a state-court suit alleging that petitioner had vio-

to exercise supplemental jurisdiction over the remaining state-law
claims under §1367(c)(3), which allows such a course if the court “has
dismissed all claims over which it has original jurisdiction”; and re-

characterized as based on a “lack of subject matter jurisdiction” over
the state-law claims, §1447(c), and was therefore “not reviewable on
appeal,” §1447(d).
Held: A district court’s order remanding a case to state court after de-
