4. Mr Metwally now makes two applications. The first is to vary the order made by this Court on 22 November 1984, by deleting the declaration that the Tribunal had no power or jurisdiction in the matter. The second is for an order removing into this Court that part of the cause pending in the Court of Appeal which raises the question whether the 1975 Act is a valid law of the Commonwealth with respect to external affairs or with respect to any other relevant power of the Commonwealth. It was made clear in argument that the second application was ancillary to the first. Unless the order of this Court is amended, it will not be open to Mr Metwally to raise, either in the Court of Appeal or in this Court, the question whether the 1975 Act is valid. It was further conceded in argument by Mr Bennett, who appeared before us for Mr Metwally, that the first application, even if granted, would not go far enough for his purposes. The declaration merely states compendiously the effect on the proceedings of the answer made to question (ii). That answer effectively terminated the proceedings adversely to Mr Metwally. If Mr Bennett were to succeed, it would be necessary to delete the answer to question (ii), or to amend it, so as to indicate that it is merely hypothetical and depends on an assumption, namely that the 1975 Act is valid, which remains open to challenge in these proceedings.
