The U.S. Supreme Court, 5-4, has ruled that Michigan can't block an off-reservation American Indian casino from opening because of tribal sovereignity, the Associated Press reports: "The ruling was a win for Indian tribes, which have increasingly looked to casinos as a source of revenue and have relied on immunity to shield them from government interference. But it's a disappointment for Michigan and more than a dozen others states that say the decision will interfere with their ability to crack down on unauthorized tribal casinos."
