The county auditor may designate any person who has been certified under this chapter, other than the auditor, to participate in a review conducted in the county under this chapter. Each county auditor and canvassing board shall cooperate fully during an election review by making available to the reviewing staff any material requested by the staff. The reviewing staff shall have full access to the county's election material. If ballots are reviewed by the staff, they shall be reviewed in the presence of the canvassing board or its designees. Ballots shall not leave the custody of the canvassing board. During the review and after its completion, the review staff may make appropriate recommendations to the county auditor or canvassing board, or both, to bring the county into compliance with the training required under this chapter, and the laws or rules of the state of Washington, to safeguard election material or to preserve the integrity of the elections process.
