The Commissioner may appoint any staff he considers necessary for assisting him in the exercise of his functions, one of whom shall be appointed as deputy Commissioner.

During any vacancy in the office of Commissioner or at any time when the Commissioner is for any reason unable to act, the deputy Commissioner shall exercise his functions (and any property or rights vested in the Commissioner may accordingly be dealt with by the deputy as if vested in him).

Without prejudice to sub-paragraph (2), any member of the Commissioner’s staff may, so far as authorised by him, exercise any of his functions.
