Colo. Rev. Stat. § 1-13-102
Irregularities or defects in the mode of calling, giving notice of, convening, holding, or conducting any general, primary, or congressional vacancy election authorized by law constitute no defense to a prosecution for a violation of this code. When an offense is committed in relation to any general, primary, or congressional vacancy election, an indictment, information, or complaint for such offense is sufficient if it alleges that such election was authorized by law without stating the call or notice of the election, the names of the judges holding such election, or the names of the persons voted for at such election. Judicial notice shall be taken of the holding of any general, primary, or congressional vacancy election.
C.R.S. § 1-13-102
