On December 17, 2013, the Arizona Supreme Court found House Bill 2593 to be constitutional, allowing newer and higher political contribution limits to take effect.

On October 15, 2013, a state Court of Appeals had directed the secretary of state not to enforce the new law, which had become effective on September 13, 2013. The lawsuit challenging the constitutionality of the new law was brought by the Citizens Clean Elections Commission and others from the state.

Individuals and noncertified political committees may now give $2,000 to candidates running for legislative and statewide offices who do not participate in the state’s Citizens Clean Elections Act campaign financing system. Contributions made to candidates running for local office may be made in amounts up to $2,500. Contribution limits by committees certified by the secretary of state have also been increased.

Additionally, H.B. 2593 removes aggregate contribution limitations for individuals and some political committees.
