Duro v. Reina
Headline: Court blocks tribal criminal prosecution of Indians who are not tribe members, limiting tribal criminal power and pushing responsibility for minor reservation crimes toward federal, state, or congressional solutions.
Holding: The Court held that a tribe’s retained sovereignty does not include the authority to impose criminal sanctions on an Indian who is not a member of that tribe.
- Prevents tribes from criminally prosecuting nonmember Indians on reservations.
- Shifts enforcement gap to federal, state, or Congress for minor reservation crimes.
- Requires tribes to rely on other authorities for nonmember offenders.
Summary
Background
Albert Duro, an enrolled member of the Torres‑Martinez Band but not of the Salt River Pima‑Maricopa Community, was arrested after an incident on the Salt River Reservation. A federal murder indictment was later dismissed, and the Pima‑Maricopa tribal court charged him with a misdemeanor firing‑weapon offense. At the time, tribal criminal penalties were limited by federal law to six months’ imprisonment and a $500 fine.
Reasoning
The Supreme Court faced the question whether a tribe can criminally punish an Indian who is not a member of that tribe. Relying on earlier decisions (Oliphant and Wheeler), the Court said tribal sovereignty that is retained today covers only internal self‑governance of members. The majority concluded that tribes lack inherent criminal authority over nonmember Indians, because criminal punishment implicates citizens’ liberties and tribal courts do not provide all constitutional protections in the same way federal courts do. The Court rejected arguments based on history, contacts with the reservation, and fears of a practical law‑enforcement gap.
Real world impact
The ruling means tribal criminal courts may not try Indians who are not enrolled members of that tribe. Minor‑offense enforcement involving nonmember Indians must rely on federal statutes, state authority (where accepted), intergovernmental agreements, or action by Congress to change the jurisdictional scheme. The Court emphasized that Congress remains the proper actor to address any enforcement gaps.
Dissents or concurrances
Justice Brennan, joined by Justice Marshall, dissented, arguing history and statutes support tribal authority over all Indians and warning the decision creates a legal void leaving some offenses unpunished. The dissent urged deference to tribal self‑government and Congress’s role instead of a judicially created limit.
