HB 524 proposes a new process for reviewing and approving municipal initiatives and referendums in home-rule municipalities. It requires municipalities to submit measures proposed via petition to the Texas Attorney General for a review of compliance with state law before ordering an election. The Attorney General has 30 days to determine if any portion of the measure violates state law. If the Attorney General finds the measure noncompliant, the municipality cannot hold an election unless a court rules otherwise. If the Attorney General fails to act within the specified timeframe, the municipality must proceed with the election. The bill also establishes that municipal charter provisions conflicting with these requirements will be overridden, extending timelines for elections as necessary to comply.
