The chairperson of the Board shall serve as the Chief Administrative Judge of the Board.
In addition to participating in the hearing of cases, the Chief Administrative Judge shall oversee the administrative activities of the Board and shall provide, within approved budgetary ceilings, for the staffing of the Board with nonmember personnel. These persons shall be responsible to and shall function under the direction, supervision, and control of the Chief Administrative Judge.
In the case of a vacancy in the position of the Chief Administrative Judge, or his or her absence or disability, the administrative judge who has the senior length of service shall serve as the Acting Chief Administrative Judge and exercise all of the authority, duties, and responsibilities of the Chief Administrative Judge.

The Chief Administrative Judge shall assign and, as necessary, reassign cases and administrative judges to panels and shall designate one of the panel members as the presiding judge having the lead responsibility for the management of a particular case.
The Chief Administrative Judge may authorize the performance by another administrative judge or Board employee of any function of the Chief Administrative Judge, except that, as provided by law, only administrative judges may hear and decide cases. The attendance of at least two members of the Board shall constitute a quorum.
