HB 631 establishes new standards for ballot propositions and petitions in municipal elections. Referred to as the Ballot Measure Election Integrity Act of 2025, it requires that ballot proposition language be identical to the caption used in the corresponding petition. The bill also provides a mechanism for citizens to challenge ballot language in court through a writ of mandamus, with expedited judicial review. Additionally, the Secretary of State is tasked with reviewing and potentially modifying invalid captions while issuing standardized petition forms for statewide use. This measure aims to enhance transparency and standardization in municipal ballot processes​.
