port its conclusion that venue was authorized by § 27 of the 1934 Act. Finally, disagreeing with the District Court, the Court of Appeals concluded that venue in the Northern District of Texas was also proper under the general federal venue provision, 28 U. S. C. § 1391 (b), because the allegedly invalid restraint against Great Western occurred there and it was accordingly “the judicial district ... in which the claim arose.” Great Western United Corp. v. Kidwell, 577 F. 2d 1256, 1265-1274. On the merits, the Court of Appeals agreed with the analysis of the District Court. Id., at 1274-1287.
We noted probable jurisdiction of the appeal. 439 U. S. 1065. Without reaching either the merits or the constitutional question arising out of the attempt to assert personal jurisdiction over appellants, we now reverse because venue did not lie in the Northern District of Texas.

The question of personal jurisdiction, which goes to the court's power to exercise control over the parties, is typically decided in advance of venue, which is primarily a matter of choosing a convenient forum. See generally C. Wright, A. Miller, & E. Cooper, Federal Practice and Procedure § 3801, pp. 5-6 (1976) (hereinafter Wright, Miller, & Cooper). On the other hand, neither personal jurisdiction nor venue is fundamentally preliminary in the sense that subject-matter jurisdiction is, for both are personal privileges of the defendant, rather than absolute strictures on the court, and both may be waived by the parties. See Olberding v. Illinois Central B. Co., 346 U. S. 338, 340; Neirbo Co. v. Bethlehem Corp., 308 U. S. 165, 167-168. Accordingly, when there is a sound prudential justification for doing so, we conclude that a court may reverse the normal order of considering personal jurisdiction and venue.
Such a justification exists in this case. Although for the reasons discussed in Part II, infra, it is clear that § 27 of the 1934 Act does not provide a basis for personal jurisdiction, the
