(2) A question shall not be referred to the Federal Court of Australia by virtue of the last preceding subsection in pursuance of a request made after the date on which the Tribunal gave its decision in the proceedings unless the request is made before the expiration of such period as is prescribed.
(3) If the Tribunal, after giving its decision in any proceedings, refuses a request to refer a question to the Federal Court of Australia, the party by whom the request was made may, within such period as is prescribed, apply to the Federal Court of Australia for an order directing the Tribunal to refer the question to the Federal Court of Australia.

(a) the Tribunal shall reconsider the matter in dispute and, if it considers it necessary to do so for the purpose of giving effect to the decision of the Federal Court of Australia, shall give to the parties to the proceedings a further opportunity of presenting their cases; and
(b) if it appears to the Tribunal to be appropriate, and in conformity with the decision of the Federal Court of Australia, to do so, the Tribunal shall make such order revoking or modifying any order previously made by it in the proceedings, or, in the case of proceedings under section 157 where the Tribunal refused to make an order, shall make such order under that section, as the Tribunal considers to be appropriate.
