Paragraph 35
In a case where the Chief Commissioner considers that it is impracticable, or would be likely to cause undue delay, for an application for leave to appeal to the Court of Appeal to be determined by the Commissioner who decided the case, that application shall be determined —
where the decision was a decision of an individual Commissioner, by the Chief Commissioner or a Commissioner selected by the Chief Commissioner, and
where the decision was a decision of a Tribunal of Commissioners, by a differently constituted Tribunal of Commissioners selected by the Chief Commissioner.
If the office of Chief Commissioner is vacant, or if the Chief Commissioner is unable to act, sub-paragraph (1) above shall have effect as if the expression “the Chief Commissioner” referred to such other of the Commissioners as may have been nominated to act for the purpose either by the Chief Commissioner or, if he has not made such a nomination, by the Lord Chancellor.
