Ruhrgas AG v. Marathon Oil Co.
Citation
526 U.S. 574 (1999)
Facts
Marathon Oil filed suit in Texas state court; defendants removed to federal court on diversity grounds. Ruhrgas AG, a German company, moved to dismiss for lack of personal jurisdiction. Marathon moved to remand for lack of subject matter jurisdiction. The Fifth Circuit had held that courts must always resolve subject matter jurisdiction first. The Supreme Court granted certiorari to resolve whether personal jurisdiction could be decided before subject matter jurisdiction.
Issue
May a federal court dismiss a case for lack of personal jurisdiction without first resolving whether it has subject matter jurisdiction?
Holding
Yes. The Court held unanimously that federal courts may address personal jurisdiction before subject matter jurisdiction when the personal jurisdiction question is straightforward and the subject matter jurisdiction question is difficult, and resolving personal jurisdiction will dispose of the case cleanly.
Rule / Doctrine
There is no inflexible rule that subject matter jurisdiction must be decided first. Courts have discretion to sequence jurisdictional inquiries based on efficiency and ease of resolution. The key limitation: courts cannot reach the merits without jurisdiction; the choice is only which jurisdictional defect to address first.
Significance
Ruhrgas rejected the “hypothetical jurisdiction” doctrine and the rigid SMJ-first rule. It acknowledges that SMJ concerns the sovereign’s power while PJ concerns the individual’s liberty interest, but holds that this difference does not mandate a fixed sequencing rule. Practically important when SMJ is uncertain (e.g., complex diversity or federal question issues) but PJ is clearly lacking.
