CHAPTER 12 - PROCEDURE FOR PRECINCT HAND COUNT AND EARLY BALLOT AUDIT

For each candidate and issue contest for which the Secretary of State is the filing officer, the County Officer shall: (1) conduct a hand count at one or more secure facilities of at least two per cent of the precincts/polling locations in that county or two precinct/polling locations, whichever is greater; (2) conduct a manual audit of early ballots equal to one per cent of the total number of early ballots cast or 5,000 early ballots, whichever is less, and (3) in the event of a recount, conduct a hand count of at least five per cent of the precincts for the recounted race in that county. The hand count activities will take place in one or more secure facilities.

[ARS ยงยง 16-602(B), 16-602(G), & 16-663(B)] I. Purpose

The purpose of the Precinct Hand Count and Early Ballot Audit is to compare the results of the machine count to the hand count to assure that the machines are working properly and accurately counting the votes. The purpose of this procedure is to assure that the Precinct Hand Count and Early Ballot Audit are conducted in a uniform manner in every county. Other than determining the intent of the voter, no other determinations regarding the ballot shall be made during the Precinct Hand Count and Early Ballot Audit.
