Background & Facts
Billy Jo Lara, an enrolled member of the Turtle Mountain Chippewa Tribe, was prosecuted by the Spirit Lake Tribal Court for assaulting a federal officer on the Spirit Lake Reservation. He pleaded guilty in tribal court. The federal government then prosecuted him for the same conduct in federal court. Lara raised a Double Jeopardy defense, arguing that the tribal prosecution and the federal prosecution were both exercises of federal power and therefore barred by the Fifth Amendment.
The case turned on a profound question: when a tribal court prosecutes a non-member Indian, is the tribe exercising its own inherent sovereign power, or is it exercising delegated federal power? If the former, no double jeopardy. If the latter, the federal prosecution would have to be dismissed.
In 1990, the Court had held in Duro v. Reina that tribes lacked criminal jurisdiction over non-member Indians. Congress overruled Duro in 1991 — the "Duro fix." The Lara case asked whether that fix was constitutional.
The Court's Holding
The Court upheld the Duro fix and Lara's successive prosecutions. Justice Breyer, writing for a 7-2 majority, held that Congress has the constitutional power to recognize the inherent sovereign authority of Indian tribes — including criminal jurisdiction over non-member Indians. Tribal sovereignty is inherent, not delegated. Congress can adjust the scope of recognized tribal sovereignty by statute, and when it does, the tribe is exercising its own power, not federal power.
Key Holding:
Tribes possess inherent sovereign authority. Congress's power over Indian affairs includes the authority to recognize (not just delegate) inherent tribal sovereign powers. When tribes prosecute under that recognized authority, they exercise their own power — not federal power. There is NO constitutional impediment to Congress restoring tribal jurisdiction by statute.
Key Language
"The Constitution grants Congress broad general powers to legislate in respect to Indian tribes, powers that we have consistently described as 'plenary and exclusive.'"
"Congress, with this Court's approval, has interpreted the Constitution's 'plenary' grants of power as authorizing it to enact legislation that both restricts and, in turn, relaxes those restrictions on tribal sovereign authority."
"We assume, for argument's sake, that the Constitution authorizes Congress to enact legislation that recognizes a tribe's inherent power..."
Why Lara Is the Key to Restoring P.L. 280 Tribal Jurisdiction
Lara is the case that proves the constitutional path to undo P.L. 280 is wide open. If Congress can recognize and restore tribal criminal jurisdiction over non-member Indians without constitutional impediment, then Congress can certainly restore the jurisdiction P.L. 280 stripped from California tribes over their own members.
The doctrinal architecture is precisely what ATN needs:
- 1. Tribal sovereignty is inherent, not delegated. P.L. 280 did not "give" California any sovereign power — it suspended the recognized scope of inherent tribal authority.
- 2. Congress can "relax restrictions" on tribal sovereignty. A repeal of P.L. 280 — or a tribal-initiated retrocession statute — would simply be Congress relaxing a restriction it had previously imposed.
- 3. When the restriction is relaxed, tribes exercise their own power. The day after Congress repeals P.L. 280, ATN's tribal court is exercising inherent authority — not federally delegated authority.
- 4. No constitutional barrier exists. The Court has affirmed Congress's "plenary and exclusive" power. Brackeen reaffirmed it. Lara explained the mechanism.
- 5. The "Duro fix" model is the template. Congress overruled a Supreme Court decision restricting tribal jurisdiction in one year. A "P.L. 280 fix" would follow the same legislative path.
Lara also matters for the now: even without congressional action, the case establishes that tribal courts in P.L. 280 states already exercise inherent sovereignty. This is the doctrinal foundation for Walker v. Rushing and the DOJ's concurrent jurisdiction memo. ATN can establish a tribal court today and claim Lara's inherent-authority pedigree.
