Which method allows citizens to propose laws or amendments in Arizona?

The method that allows citizens to propose laws or amendments in Arizona is the initiative process. This process enables registered voters to draft legislation or constitutional amendments and then submit them for approval through a ballot measure. When a sufficient number of signatures from registered voters is collected in support of the proposed law or amendment, it moves forward to be placed on the ballot during an election. If passed by a majority of voters, the proposed measure becomes law.

This direct participation in the legislative process empowers citizens to address issues they deem important, circumventing traditional legislative channels which may not always reflect public sentiment. The initiative process is a significant feature of Arizona's democratic system, allowing for grassroots involvement in shaping state laws and policies.
