Tribes today practice unlimited sovereignty: they are not limited by the United States Constitution or state or local governments.

That statement is false

Explanation:

It is true that the Native American tribes were given with the power of sovereignty. But this only limited to their community. They have the right to settles disputes or create social norms that applicable to the members of their community.
