On behalf of the defendant it was, however, submitted that the law to be applied in the Supreme Court would be materially different in two respects from that which would be applied if the matter remained in this Court. In the first place, s. 61 of the Evidence Act 1898 N.S.W., as amended, provides that when the Attorney-General for that State certifies in writing that in his opinion any written or oral communication described therein in a government communication and is confidential, and that the disclosure of such communication in any legal proceedings described in the certificate is not in the public interest, the communication shall not be disclosed or be admissible in evidence in those proceedings. It was submitted that the provisions of s. 79 of the Judiciary Act would not render s. 61 applicable to proceedings in this Court or in the Federal Court, although the section would be available to be used by the Attorney-General if the proceedings were heard in the Supreme Court. If it were correct to say that the Attorney-General for New South Wales might, by his certificate, prevent the defendant from adducing relevant evidence in one court but not in another, I should have no hesitation in remitting the matter to the latter court. However I need not consider whether the defendant's submission is correct, because both Mr. Rayment for the plaintiff and the Solicitor-General for the State of New South Wales have formally conceded that if s. 61 has no application to the Federal Court or the High Court it would equally have no application to the Supreme Court in the present case. In the light of this concession, which counsel would, if necessary, repeat in the Supreme Court, s. 61 will have no different operation, if it has any operation at all, whether the matter is heard in the Federal Court or in the Supreme Court.
