You cannot appeal to superior court until you have exhausted your administrative remedies. Appeal of the Board decision is to an administrative law judge. All of the details informing you of how to appeal the decision would have been included in the decision itself. Do not skip the ALJ step. If you disagree with that decision, then you appeal in the administrative law court appeals board. It is only after you have exhausted all of those steps that you get into superior court.
Best of luck to you.
