01-020 C.M.R. ch. 3, r. 14
Hearings held subject to the requirements of this chapter shall be conducted before the Board. The chairperson of the Board shall serve as presiding officer, but if he or she is not present, those Board members in attendance shall choose a presiding officer from among them. The chairperson or presiding officer shall administer oaths and affirmations conduct the hearing, set the time and place for continued hearings, determine the order of testimony, fix the time for filing of such additional evidence, briefs and other written submissions as may be allowed or required make rulings as to the admissibility of evidence, the existence of privileges and other evidentiary matter, and take such other action of a similar nature relating to the proceeding as may be necessary. Whenever a presiding officer is disqualified or it becomes impracticable for him to continue in that capacity, another presiding officer may be chosen to continue the hearing, provided that, if it is shown that the substitution will cause substantial prejudice to any party, the substitute presiding officer shall commence the hearing anew.
