Background & Facts
Merle Denezpi, a Navajo Nation member, was accused of sexually assaulting a woman in a home on the Ute Mountain Ute Reservation. He was first prosecuted in the CFR (Court of Federal Regulations) court — a tribal court funded and operated by the Bureau of Indian Affairs — for assault and battery under the Ute Mountain Ute tribal code. He pleaded guilty and served 140 days.
Denezpi was then indicted in federal court for aggravated sexual abuse under the Major Crimes Act. He argued that the federal prosecution violated the Double Jeopardy Clause because he had already been prosecuted for the same conduct in the CFR court.
The question was whether a CFR court prosecution constitutes a "tribal" prosecution (separate sovereign = no double jeopardy) or a "federal" prosecution (same sovereign = double jeopardy bars second prosecution).
The Court's Holding
Justice Barrett, writing for the 6-3 majority, held that the CFR court prosecution was an exercise of tribal sovereignty — not federal sovereignty — even though the court was federally administered. Because tribes and the federal government are separate sovereigns, the Double Jeopardy Clause does not bar successive prosecutions by each.
Key Holding:
Tribes and the federal government are separate sovereigns for Double Jeopardy purposes — even when the tribal court is a federally administered CFR court. A tribal prosecution followed by a federal prosecution for the same conduct does not violate the Fifth Amendment. The source of the prosecuting authority — tribal sovereignty vs. federal sovereignty — determines the double jeopardy analysis, not the institutional form of the court.
Key Language
"The Double Jeopardy Clause does not bar successive prosecutions by separate sovereigns. Indian tribes are separate sovereigns from the Federal Government."
"The ultimate source of a tribe's power to prosecute is its own sovereignty, not a delegation of federal authority. This remains true even when the prosecution occurs in a CFR court."
How This Case Confirms ATN's Separate Sovereignty
- 1. ATN is a separate sovereign. Denezpi is the most recent SCOTUS confirmation that tribal criminal authority flows from the tribe's own sovereignty — not from federal delegation. ATN's prosecutorial authority is inherent, not borrowed.
- 2. Concurrent jurisdiction is real. Under P.L. 280 + Walker v. Rushing, ATN has concurrent criminal jurisdiction alongside California. Under Denezpi, an ATN tribal court prosecution does not bar a subsequent state prosecution (or vice versa) because they are separate sovereigns.
- 3. Strengthens tribal court deterrence. Knowing that tribal prosecution doesn't preclude federal or state prosecution means ATN's tribal court can act quickly on criminal conduct without worrying about foreclosing other prosecutions.
- 4. CFR courts exercise tribal authority. Even federally administered courts exercise tribal — not federal — sovereignty. This confirms that the source of authority matters, not the institutional wrapper.
