So many states contain Native American Reservations, including some in Republican states. It would be a novel approach to getting around these ridiculous bans. As I understand it, only federal and tribal laws apply to tribal members and crimes committed on their land. With that interpretation, states can pass whatever laws they want, they will only apply on sovereign Indian Nations if it is a law passed by the tribe itself or by federal law. If Roe falls, everything I read says that "women's health" decisions will be decided by the state, therefore not necessarily applicable to Indian Nations.
