El Paso Natural Gas Co. v. Neztsosie

Background

Two Navajo Nation members sued mining companies in tribal courts, claiming injuries from uranium mining on reservation lands under Navajo tort law. The companies went to federal court to stop the tribal suits, arguing the claims were governed by the Price‑Anderson Act, a federal law that treats certain nuclear public‑liability claims as federal and allows removal to federal courts for centralized handling. The district court declined to decide whether the claims fell under Price‑Anderson because it thought it must let the tribal courts decide their own jurisdiction first.

Reasoning

The Court considered whether the usual rule that federal courts wait for tribal courts to assess their own jurisdiction should apply when Congress has given a statute a clear preference for federal forums. The Price‑Anderson Act converts public‑liability suits into federal actions and authorizes removal from state courts so claims can be consolidated and handled efficiently. The Court held that applying tribal‑court exhaustion here would frustrate Congress’s express goals of speed, consolidation, and efficient resolution, and that silence about tribal‑court removal was likely inadvertent rather than an intent to require exhaustion.

Real world impact

The judgment from the court of appeals was vacated, and the case was sent back so the district court can decide whether the tribal claims are Price‑Anderson actions without waiting for tribal‑court jurisdictional rulings. That means defendants in similar nuclear public‑liability suits can seek immediate federal resolution rather than being forced to await tribal‑court decisions. This ruling resolves procedure, not the underlying merits of the injury claims, which remain for later determination.
