Justia Opinion Summary and Annotations

The Major Crimes Act (MCA) provides that, within “the Indian country,” “[a]ny Indian who commits” certain enumerated offenses “shall be subject to the same law and penalties as all other persons committing any of [those] offenses, within the exclusive jurisdiction of the United States,” 18 U.S.C. 1153(a). “Indian country” includes “all land within the limits of any Indian reservation under the jurisdiction of the United States Government.” McGirt was convicted by an Oklahoma state court of sexual offenses. He unsuccessfully argued in state postconviction proceedings that the state lacked jurisdiction to prosecute him because he is an enrolled member of the Seminole Nation and his crimes took place on the Creek Reservation.

The Supreme Court held that McGirt was entitled to a federal trial. For MCA purposes, land reserved for the Creek Nation since the 19th century remains “Indian country.” An 1856 Treaty promised that “no portion” of Creek lands “would ever be embraced or included within, or annexed to, any Territory or State,” 11 Stat. 700, and that the Creeks would have the “unrestricted right of self-government,” with “full jurisdiction” over enrolled Tribe members. Once a federal reservation is established, only Congress can diminish or disestablish it. Congress did not end the Creek Reservation during the “allotment era,” when Congress sought to pressure many tribes to abandon their communal lifestyles and parcel their lands into smaller lots owned by individual tribal members. Other limitations on the promised right to self-governance, including abolishing the Creeks’ tribal courts and requiring Presidential approval for certain tribal ordinances fell short of eliminating all tribal interest in the contested lands. Many of Oklahoma’s arguments rest “on state prosecutorial practices that defy the MCA, rather than on the law’s plain terms.” Acknowledging the potential consequences of its ruling, such as unsettling convictions and frustrating the state’s ability to prosecute future crimes, the Court stated that Oklahoma and its tribes have proven that they can work successfully together and Congress remains free to supplement its statutory directions about the lands.

Primary Holding

Land reserved for the Creek Nation remains “Indian Country” so that crimes committed on that land must be prosecuted in federal court under the Major Crimes Act.
