gory. See id., at 377 (burden rests on party asserting jurisdiction).

"[A]ncillary jurisdiction typically involves claims by a defending party haled into court against his will, or by another person whose rights might be irretrievably lost unless he could assert them in an ongoing action in a federal court." Owen Equipment & Erection Co. v. Kroger, 437 U. S. 365, 376 (1978). Ancillary jurisdiction may extend to claims having a factual and logical dependence on "the primary lawsuit," ibid., but that primary lawsuit must contain an independent basis for federal jurisdiction. The court must have jurisdiction over a case or controversy before it may assert jurisdiction over ancillary claims. See Mine Workers v. Gibbs, 383 U. S. 715, 725 (1966). In a subsequent lawsuit involving claims with no independent basis for jurisdiction, a federal court lacks the threshold jurisdictional power that exists when ancillary claims are asserted in the same proceeding as the claims conferring federal jurisdiction. See Kokkonen, supra, at 380-381; H. C. Cook Co. v. Beecher, 217 U. S. 497, 498-499 (1910). Consequently, claims alleged to be factually interdependent with and, hence, ancillary to claims brought in an earlier federal lawsuit will not support federal jurisdiction over a subsequent lawsuit. The basis of the doctrine of ancillary jurisdiction is the practical need "to protect legal rights or effectively to resolve an entire, logically entwined lawsuit." Kroger, 437 U. S., at 377. But once judgment was entered in the original ERISA suit, the ability to resolve simultaneously factually intertwined issues vanished. As in Kroger, "neither the convenience of litigants nor considerations of judicial economy" can justify the extension of ancillary jurisdiction over Thomas' claims in this subsequent proceeding. Ibid.
In any event, there is insufficient factual dependence between the claims raised in Thomas' first and second suits to justify the extension of ancillary jurisdiction. Thomas'
