Idaho Code § 34-2417
Before preparing the voting machines or vote tally systems for any election, the county clerk shall mail to the chairman of the county or legislative district central committees of each political party who has notified such clerk that notice is desired, a written notice stating the time and place or places where voting machines or vote tally systems will be prepared for the election. At such times and places, one (1) representative of each political party is entitled to be present and see that the machines or vote tally systems are properly prepared and placed in proper condition and order for use at the election. In nonpartisan elections each candidate may designate one (1) representative who has the same powers as the political party representatives. The political party and candidate representatives shall certify that they have witnessed the testing and preparation of the machines or vote tally systems. The certificates shall be filed in the office of the county clerk.
