Article 6 Casual vacancies
A casual vacancy arising in the office of -
a chair appointed by the Secretary of State under article 3(1)(a),
a director appointed by the Secretary of State under article 3(1)(b), or
a director appointed by the Board under article 3(1)(c),
must, unless it is not reasonably practicable to do so, be filled by the appointment of a director by the Secretary of State or, as the case may be, the Board in accordance with article 3(2) to (11).
The Secretary of State may fill a casual vacancy in the office of the chair by appointing as the chair a person who is already a director of the Board appointed under article 3(1)(b) or (c) and, if the Secretary of State does so, the appointment shall be deemed to create a casual vacancy in the office of the director who is appointed as the chair.
A director appointed to fill a casual vacancy under this article shall, subject to paragraph 4 of the Schedule to this Order, hold office during the remainder of the term for which the director whom he or she replaces was appointed or such other period (not exceeding three years) as the appointing person or body may specify.
