What is required for an amendment to pass once proposed by the Arizona Legislature?

For an amendment to the Arizona Constitution to pass after being proposed by the Arizona Legislature, it must receive a two-thirds majority vote in both the House of Representatives and the Senate. This requirement ensures that a significant consensus exists among the elected representatives before a constitutional change is made, reflecting the importance and potential impact of such amendments on the foundational law of the state.

It's also key to understand that this rigorous process serves as a safeguard against impulsive changes to the Constitution, fostering careful consideration and broad support for alterations to the state's governing document.

Other options do not fit the constitutional process in Arizona. For instance, while a majority vote from the statewide electorate does come into play for certain types of measures, it is not the initial requirement once the Legislature proposes an amendment. Approval by the Governor is not necessary for constitutional amendments in Arizona; the legislative process alone suffices. Moreover, amendments are not contingent upon approval from local municipalities, as the state constitution is not subject to local governance structures in this regard.
