The Chief Justice, or, in case of his inability to do so, one of the other justices of the Supreme Court, shall summon the Council to meet at Richmond during the month of October in each year, and at such other times and places as the Chief Justice, or such other justice, may designate. If any member, when so summoned, shall for any cause be unable to attend, he shall promptly notify the justice who issued the summons, of such fact, and such justice shall thereupon summon some other person possessing similar qualifications to attend and act in his stead. Each member or other person, when so summoned, shall attend and remain throughout the proceedings of the Council, unless excused by the presiding officer, and shall advise as to any matters in respect to which, in his opinion, the administration of justice in the courts of this Commonwealth may be improved. The Chief Justice or, in case of his inability to do so, one of the other justices of the Supreme Court, may summon the chairman or members of any committee to meet at such time and place as the Chief Justice, or such other justice, may designate.
