A judge has ruled that Arizona campaign finance laws requiring political committees to register and report their spending and fundraising are unconstitutional.
The Arizona Capitol Times reports that the ruling won't affect campaigns this election cycle but that it could upend the state's campaign finance system for future elections.
Assistant Secretary of State Jim Drake says his office will appeal the ruling by Judge Crane McClennen of Maricopa County Superior Court.
McClennen overturned an enforcement order against a Democratic-backed group that aired an ad criticizing Republican Horne during the 2010 general election campaign for state attorney general.
McClennen ruled that the state's requirements are unconstitutional because the ads were issue-oriented speech that didn't expressly advocate for or against a candidate.
