Whether a federal court must always establish subject-matter jurisdiction before it may dismiss an action for lack of personal jurisdiction.
Holding
No. Although a federal court ordinarily should resolve subject-matter jurisdiction first, there is no inflexible hierarchy requiring that question to precede personal jurisdiction in every case.
Reasoning
Steel Co. requires a federal court to establish subject-matter jurisdiction before deciding the merits because a merits ruling without jurisdiction would improperly assume law-declaring authority. But a dismissal for lack of personal jurisdiction is not a decision on the merits. It simply denies the case an audience in that court, so it does not create the separation-of-powers problem that animated Steel Co.'s jurisdiction-before-merits rule.
Subject-matter and personal jurisdiction protect different interests, but neither is invariably more fundamental. Subject-matter jurisdiction defines the institutional limits imposed on federal courts by the Constitution and Congress and cannot be waived. Personal jurisdiction protects an individual liberty interest under the Due Process Clause and may be waived. Yet personal jurisdiction is also an essential limit on a court's adjudicatory authority, and a court lacking it cannot bind the defendant on the merits.
Federal courts already may choose among certain threshold, non-merits grounds for declining to decide a case. For example, they may abstain or decline supplemental jurisdiction without first resolving every possible question about their power to reach the underlying claims. Addressing a straightforward personal-jurisdiction defect first fits that established practice.
