Who has the authority to amend the Texas Constitution?

The authority to amend the Texas Constitution lies with the Texas Legislature, but the process requires voter approval following the legislature's action. This reflects a system of checks and balances, where the legislature proposes amendments during its regular session, and these proposals must then be submitted to the voters of Texas for a referendum. This method ensures that significant changes to the foundational legal document of the state have public support.

While the Governor may influence the legislative agenda, they do not have unilateral power to amend the Constitution. The Texas Judiciary interprets the Constitution but does not participate in the amendment process. Similarly, local governments do not have the authority to amend the state Constitution, as their powers are limited to local ordinances and regulations rather than state constitutional law. Thus, the correct answer highlights the collaborative and democratic process established for amending the Texas Constitution.
