The Supreme Court heard oral arguments Wednesday in a follow-up case to a landmark decision on tribal sovereignty handed down by the court just two years ago. Justices will decide whether Oklahoma and other states have criminal jurisdiction over crimes committed by non-Indigenous people against Native people within Indian reservations. This case follows the landmark 2020 ruling, McGirt v. Oklahoma, which found that state authorities cannot criminally prosecute Indigenous peoples under state or local laws; they should instead face justice under tribal or federal courts.
