DENVER - Gov. John Hickenlooper signed an Executive Order Thursday that designates Sept. 10, 2013, as the special recall election date in Senate District 11 and Senate District 3.

The order comes after a Denver judge refused to stop the recall elections for two Colorado Democratic senators who supported gun restrictions, even though the lawmakers are challenging the validity of the petitions.

Denver District Court Robert Hyatt made the decision Thursday afternoon.

Colorado Springs Senate President John Morse and Pueblo Sen. Angela Giron argue the recall petitions against them are invalid because they didn't ask for an election for a successor like the state constitution mandates.

The lawmakers sought a preliminary injunction from the judge.
