Colorado Revised Statutes Title 1. Elections § 1-13.5-706. Judge to watch voting machines

The election judges shall designate at least one judge to be stationed beside the entrance to the voting machine or voting booth during the entire period of the election to see that it is properly closed after an elector has entered to vote. At such intervals as the judge deems proper or necessary, the judge shall examine the face of the machine to ascertain whether it has been defaced or injured, to detect the wrongdoer, and to repair any injury.
