The Tenth Circuit will hear oral arguments in Riddle v Hickenlooper, 13-1108, on September 26, 2013, at 9 a.m., in Denver. This is the case that challenges unequal contribution limits in Colorado. Colorado law says an individual may donate $400 to a legislative candidate who is nominated in a primary, but only $200 to a legislative candidate who is nominated by convention (i.e., a typical minor party candidate), or by petition (i.e., an independent candidate), or a write-in candidate.
The U.S. District Court had upheld the unequal contribution limits, even though the U.S. Supreme Court in Davis v Federal Election Commission ruled that unequal contribution limits for all candidates for a particular office are unconstitutional.
This particular case was filed on behalf of Joelle Riddle, who wanted to donate $400 to Kathleen Curry, a write-in candidate in 2010. Curry was a viable candidate, who wanted to be on the ballot as an independent, but a restrictive Colorado ballot access law kept her off the ballot because she had too recently been a registered Democrat. She was the incumbent.
