Paragraph 13
There shall be a chairman and deputy chairman of the Commissioners, each of whom shall be appointed by the Commissioners from amongst the commissioners then serving (other than the designated officer) and, in the case of the chairman, from such of the Commissioners as have already served a full three year term.
A commissioner appointed as chairman or deputy chairman shall serve in that capacity for a period of one year unless before the expiry of that term the commissioner dies, resigns or becomes disqualified for office but shall be eligible for re-appointment.
On a casual vacancy occurring in the office of chairman or deputy chairman of the Commissioners, the vacancy shall be filled by those of the Commissioners who are appointed under articles 5(1)(a) or 8 above at a meeting held as soon as practicable after that vacancy occurs.
In the absence of the chairman, the deputy chairman may exercise all the powers of the chairman.
If, at a meeting of the Commissioners, neither the chairman nor the deputy chairman is present, the commissioners present shall choose one of their number to be chairman of the meeting.
