36.—(1) When a party has applied for a review and the application has not been refused after the preliminary consideration above, the decision shall be reviewed by the chairman or tribunal who made the original decision. If that is not practicable a different chairman or tribunal (as the case may be) shall be appointed by a Regional Chairman, the Vice President or the President.
(2) Where no application has been made by a party and the decision is being reviewed on the initiative of the tribunal or chairman, the review must be carried out by the same tribunal or chairman who made the original decision and —
(a)a notice must be sent to each of the parties explaining in summary the grounds upon which it is proposed to review the decision and giving them an opportunity to give reasons why there should be no review; and
(b)such notice must be sent before the expiry of 14 days from the date on which the original decision was sent to the parties.
(3) A tribunal or chairman who reviews a decision under paragraph (1) or (2) may confirm, vary or revoke the decision. If the decision is revoked, the tribunal or chairman must order the decision to be taken again. When an order is made that the original decision be taken again, if the original decision was taken by a chairman without a hearing, the new decision may be taken without hearing the parties and if the original decision was taken at a hearing, a new hearing must be held.
