Notwithstanding the amendments made by section 149, Division 5 of Part V of the Principal Act continues to apply in relation to any decision of a Compensation Tribunal made before the commencement of this Part but, for the purposes of the exercise of the powers of the Federal Court of Australia under paragraph 95(3)(c) of the Principal Act in respect of an appeal to that Court from such a decision, the reference in that paragraph to the Compensation Tribunal shall be construed as a reference to the Administrative Appeals Tribunal which shall deal with any case remitted to it under that paragraph as if the decision appealed from were a decision of that Tribunal in a proceeding duly instituted before that Tribunal in relation to the relevant determination of the Commissioner.
