HB495 prohibits state and local agencies from implementing or enforcing federal mandates that are not explicitly authorized by the U.S. Constitution. The bill aims to limit the influence of federal regulations on state governance and reduce federal overreach.

The Montana State House of Representatives passed HB495 on April 17, 2025 by a vote of 58 to 41. We have assigned pluses to the ayes because the several states have a duty to interpose on behalf of the American people and nullify all unconstitutional acts by the federal government under Article VI of the U.S. Constitution. The U.S. Constitution established a limited federal government with "few and defined" powers. Whenever the federal government assumes undelegated powers, in flagrant violation of the 10th Amendment, interposition is necessary, and nullification of such lawless acts is the proper remedy. HB495 rightly affirms Montana's sovereignty, reinforces the proper balance of federalism, and helps protect the state and its citizens from unconstitutional federal mandates.
