Extend PL280 termination date

This bill extends the date by which Lake County may withdraw from enforcing criminal jurisdiction on the Flathead Indian Reservation. It amends the existing law (Chapter 556, Laws of 2021) to change the termination date from June 30, 2027, to June 30, 2031. The change directly affects Lake County and the State of Montana regarding their enforcement of criminal jurisdiction within the reservation. The bill makes this extension effective immediately upon passage.
