Colorado Revised Statutes Title 31. Government Municipal § 31-10-202. Submission of question to qualified taxpaying electors--oath

(1) On any question which is required by law to be submitted to qualified taxpaying electors only, if the question is submitted on paper ballots, such ballots shall be deposited in a separate ballot box reserved for that purpose. If the question is submitted on voting machines, provision shall be made to assure that only registered taxpaying electors are permitted to vote on such question. If the question is to be submitted in precincts using an electronic voting system, provision shall be made to assure that only registered taxpaying electors are permitted to vote on such question.

(2) The governing body, in its discretion, may require each registered taxpaying elector desiring to vote on a question which is submitted to qualified taxpaying electors only to sign a written oath that he has, during the twelve months next preceding the election, paid an ad valorem tax upon property situated within the municipality and owned by said person. If said elector is unable to write, he may request assistance from one of the judges of election, and such judge shall sign and witness said elector's mark.
