The Guardian reports on U.S. Supreme Court oral arguments today in a case in which the state of Michigan argues that the Bay Mills Indian Community inappropriately opened an off-reservation casino without authorization of the federal government and in violation of a state agreement. Some of the justices took a skeptical view of the position that tribal sovereignity gives extra protection against closing the casino or other action by Michigan. Justice Stephen Breyer, for one, said, "My belief is Indian tribes all over the country, operate businesses off the reservation, and businesses all over the country are regulated. And does the State, I guess, in your view not have the power to enforce the regulation against the Indian tribe?" The Guardian reported.
