History and arts: other; history museum authorities act; create. Creates new act. TIE BAR WITH: SB 1140’26, SB 1141’26
Key claim: The bill would create a new Michigan law allowing history museum authorities to be set up as special public bodies, and it cannot take effect unless companion Senate bills 1140 and 1141 also pass.
Abstract
(SB1139 · 103rd Legislature) History and arts: other; history museum authorities act; create. Creates new act. TIE BAR WITH: SB 1140’26, SB 1141’26 Sponsor: Sen. Sylvia Santana (D) + 7 co-sponsors Latest action (2026-09-15): Received On 09/10/2026
Why this matters
Creating a dedicated History Museum Authorities Act would give local communities a new special-purpose public body to fund and govern history museums, similar to existing library or convention authorities. Because the act is tie-barred to two companion bills (including one exempting museum authorities from tax increment capture), the policy stands or falls as a package — meaning economic-development and local-tax implications are inseparable from the authority framework itself.
