A person who is the subject of a criminal record and who disagrees with the refusal of the agency maintaining or submitting the record to correct, complete, or delete the record, may request a review of the refusal within twenty business days of the date of receipt of such refusal. The request for review must be in writing. If review is requested in the time allowed, the head of the agency whose record or submission has been challenged must complete the review within thirty days and make a final determination of the challenge. The head of the agency may extend the thirty-day period for an additional period not to exceed thirty business days. If the head of the agency determines that the challenge should not be allowed, he or she must state his or her reasons in a written decision, a copy of which must be provided to the subject of the record. Denial by the agency head will constitute a final decision under RCW 34.05.570. Notwithstanding this section, RCW 43.43.730 governs an individual's request to the Washington state patrol criminal records division to purge, modify, or supplement that individual's criminal history record information on file with the Washington state patrol criminal records division.
