Amend laws related to the retrocession of jurisdiction over federal lands

This bill amends Montana state laws to allow the state to accept jurisdiction over federal lands within its borders that are used for national park or military purposes. It authorizes the governor to accept such jurisdiction when the federal government offers to relinquish control over these specific lands. The law establishes a formal process requiring written notification from federal officials and mandates that the acceptance be filed with the Montana Secretary of State to become effective. This change would enable Montana to take legal control of certain federal properties currently managed by the United States government.
