A party may request administrative review of the initial order from a full hearing based on the grounds as set forth in WAC 478-121-433.

A request for administrative review must be submitted in writing to the hearing officer within twenty-one days of the date of the initial order. If one of the grounds is to consider newly discovered evidence, that evidence must be provided with the request for review.

If an administrative review is not requested within twenty-one days the initial order shall become the final order.
