Any supporting facts must be established by affidavit or other sufficient evidence. The moving party must also send a copy of the motion to the Director.

(c) The chief judge of the appropriate OHA unit or the Director may decide whether disqualification is required if the presiding officer or Board member does not withdraw under paragraph (a) of this section or in response to a motion under paragraph (b) of this section.
