Before entering upon the duties of his office, a judge of the Court of Appeals shall take the oath of office prescribed for a judge of the General Court of Justice.
The Governor on or after July 1, 1967, shall make temporary appointments to the six initial judgeships. The appointees shall serve until January 1, 1969. Their successors shall be elected at the general election for members of the General Assembly in November, 1968, and shall take office on January 1, 1969, to serve for the remainder of the unexpired term which began on January 1, 1967.
Upon the appointment of at least five judges, and the designation of a Chief Judge, the court is authorized to convene, organize, and promulgate, subject to the approval of the Supreme Court, such supplementary rules as it deems necessary and appropriate for the discharge of the judicial business lawfully assigned to it.
Effective January 1, 1969, the number of judges is increased to nine, and the Governor, on or after March 1, 1969, shall make temporary appointments to the additional judgeships thus created. The appointees shall serve until January 1, 1971. Their successors shall be elected at the general election for members of the General Assembly in November, 1970, and shall take office on January 1, 1971, to serve for the remainder of the unexpired term which began on January 1, 1969.
Effective January 1, 1977, the number of judges is increased to 12; and the Governor, on or after July 1, 1977, shall make temporary appointments to the additional judgeships thus created. The appointees shall serve until January 1, 1979.

The Court of Appeals shall sit in panels of three judges each and may also sit en banc to hear or rehear any cause upon a vote of the majority of the judges of the court. The Chief Judge insofar as practicable shall assign the members to panels in such fashion that each member sits a substantially equal number of times with each other member, shall preside when a member of a panel, and shall designate the presiding judge of the other panel or panels.
Except as may be provided in G.S. 7A-32, three judges shall constitute a quorum for the transaction of the business of the court when sitting in panels of three judges, and a majority of the then sitting judges on the Court of Appeals shall constitute a quorum for the transaction of the business of the court when sitting en banc.
In the event the Chief Judge is unable, on account of absence or temporary incapacity, to perform the duties placed upon him as Chief Judge, the Chief Justice shall appoint an acting Chief Judge from the other judges of the Court, to temporarily discharge the duties of Chief Judge.
