(a)Assignment. The AA/OHA will assign all cases subject to the Administrative Procedure Act, 5 U.S.C. 551 et seq., to an Administrative Law Judge. The AA/OHA will assign all other cases before OHA to either an Administrative Law Judge or an Administrative Judge, or, if the AA/OHA is a duly licensed attorney, to himself or herself.(b)Authority. Except as otherwise limited by this part, or by statute or other regulation, a Judge has the authority to take all appropriate action to ensure the efficient, prompt, and fair determination of a case, including, but not limited to, the authority to administer oaths and affirmations and to subpoena and examine witnesses.(c)Recusal. Upon the motion of a party, or upon the Judge's own initiative, a Judge will promptly recuse himself or herself from further participation in a case whenever disqualification is appropriate due to conflict of interest, bias, or some other significant reason. A denial of a motion for recusal may be appealed within 5 days to the AA/OHA, or to the Administrative Law Judge if the AA/OHA is the Judge, but that appeal will not stay proceedings in the case.61 FR 2683, Jan. 29, 1996, as amended at 75 FR 47441 , Aug. 6, 2010
