History and arts: other; history museum authorities act; create. Creates new act.

This bill establishes a new legal framework for history museum authorities in Michigan, specifically allowing counties to create these public corporate bodies to support historical museums located in cities with populations over 500,000. The legislation outlines the procedures for forming an authority, including the requirement for a majority vote by county commissioners and public notice, while defining the board's composition and powers to enter into contracts and manage operations. A key provision grants these authorities the ability to levy a property tax of up to 0.4 mill for a maximum of 20 years, but only if approved by a majority of voters in the county. The funds raised through this tax must be used exclusively to support nonprofit entities that provide services to the designated history museums, and the bill also mandates that board meetings be open to the public and records be accessible.
