A member of the court who assumes that he or she has grounds for disqualification or who conscientiously considers that he or she should abstain shall be replaced by another member appointed by the chairman of the court.
If a full member of the Disciplinary Board is unable to attend or abstain, or if he agrees to a request for disqualification, he may be replaced by one of the substitute members, irrespective of the departmental council on whose roll the latter is entered.
