Metajurisdiction

All courts and grand juries have metajurisdiction: they have "jurisdiction" to determine whether a case is "within their jurisdiction." See Blair v. United States, 250 U.S. 273, 283 (1919); and see United States v. Mine Workers, 330 U.S. 258, 290-91 (1947); Ex parte Paprskar, 573 S.W.2d 525, 527 (Tex. Crim. App. 1978), overruled on other grounds, Weiner v. Dial, 653 S.W.2d 786, 787 n. 1 (Tex. Crim. App. 1983); Lipshy Motorcars, Inc. v. Sovereign, 944 S.W.2d 68, 71 (Tex. App.—Dallas 1997, no writ).
