C.R.S. § 31-10-706: Judge to watch voting machines.

The judges shall designate at least one of their number to be stationed beside the entrance to the voting machine during the entire period of the election to see that it is properly closed after a voter has entered to vote. At such intervals as he 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.
