Relating to requirements and procedures in the contest of an election on a proposed constitutional amendment.

SB 1539 amends Texas election law to clarify procedures when a contest is filed over a vote on a proposed constitutional amendment. It requires the governor to delay declaring the official election result until the contest is resolved, and mandates that the court’s final judgment must direct the governor to declare the election valid or void within 10 days. These changes apply to contests filed on or after September 1, 2025, while older contests follow prior law. The bill directly affects election officials, courts, and voters involved in constitutional amendment contests.
