HCR 2025 is a proposed constitutional amendment in Arizona that seeks to establish a minimum voter approval threshold of 60% for any constitutional amendment to pass. This initiative aims to ensure that significant changes to the state constitution reflect a strong consensus among the electorate, as opposed to the current requirement of a simple majority. The new requirement will apply only to amendments submitted to voters after November 2026, and if approved, will be enacted following a proclamation by the Governor.

In addition to the approval threshold, the resolution clarifies the legislative authority regarding the initiative and referendum processes, emphasizing the rights of the electorate to propose and vote on laws independently. It outlines the necessary percentage of qualified electors for initiating measures, the procedures for filing petitions, and the governor's veto powers concerning tax-related initiatives. Furthermore, it streamlines the process for proposing constitutional amendments, ensuring that all new proposals are presented to voters at the next general election, thereby enhancing the democratic process in Arizona while protecting previously adopted amendments.
