If the State of Montana tried to prevent the Tribes from their "right" to hunt and fish these historical hunting grounds, the Tribes would file a lawsuit and the State would lose. The Department of Justice would have to represent the Tribes and defend the Tribes right to hunt and fish as it states in the Treaties.
Same $hit . . . . Different day. Trust me when I say, any lawsuit against the Tribes in an attempt to stop them would be thrown out by any judge that is aware of the laws that either govern or try to govern Indians.
