Under 1989.115, who can grant a waiver of the rules in special cases?
An Administrative Law Judge (ALJ) or the Administrative Review Board (ARB) on review may grant a waiver. The regulation expressly states that "the ALJ or the ARB on review may, upon application, and after three days’ notice to all parties, waive any rule or issue such orders that justice or the administration of TFA requires," so authority is limited to those two decisionmakers (1989.115).
