Some interesting effects of the supreme court giving half the state of oklahoma back to the indians include:
Half the state is now officially a resident on the indian reservation and therefore state sales and income taxes do not apply to them.
State road pirates (troopers) are out of their jurisdiction.
Sheriffs in those counties have no lawful authority to foreclose on anything because the tribes are the lawful authority there, not the state.
The tribal courts would have to extradite anyone charged with state crimes to a state court. So would the feds.
Anyone convicted by a state court on reservation land has grounds for appeal / demand for release because the state was outside of its jurisdiction.
Oh, the list is pretty endless.
