If, at the time of granting reconsideration, it appears to the satisfaction of the appeals board that no sufficient reason exists for taking further testimony, the appeals board may affirm, rescind, alter, or amend the order, decision, or award made and filed by the appeals board or the workers’ compensation judge and may, without further proceedings, without notice, and without setting a time and place for further hearing, enter its findings, order, decision, or award based upon the record in the case.
