On Thursday, the Colorado Court of Appeals affirmed a lower court ruling striking down rules reducing or eliminating disclosure requirements for issue committees, political committees, and more than 500 political organizations. The rules, put forth by Secretary of State Scott Gessler in 2012, also capped penalties for failure to file major contributor reports in the days leading up to an election.

Challengers argued the rules were invalid because Gessler exceeded his authority by effectively amending the Colorado constitution and campaign finance laws passed by the General Assembly.

In addition to finding the rule changes invalid, the appeals court overturned Gessler’s 2012 rule narrowing the definition of “electioneering communications.”
