Amend laws related to the retrocession of jurisdiction over federal lands

House Bill 496 amends Montana law to allow the state to accept jurisdiction over certain federal lands within its borders. The bill expands the types of federal lands for which the state can accept jurisdiction, adding lands used for military purposes to existing provisions for national parks. This means Montana can take back legal authority, either partially or wholly, from the U.S. government over these specific federal areas. The Governor is authorized to accept such retrocession of jurisdiction, which becomes effective once the acceptance is filed with the Montana Secretary of State.
