19. Whilst it may be true the Court will not interfere in what I would call the intra-mural deliberative activities of the Parliament, it has both a right and a duty to interfere if the constitutionally required process of law-making is not properly carried out. In this connexion, we have the guidance of the Privy Council in Rediffusion (Hong Kong) Ltd. v. Attorney-General (Hong Kong) (1970) AC 1136 . There Lord Diplock, speaking for the Board, pointed out the approval of the Privy Council of Trethowan v Peden (1930) 31 SR (NSW) 183 , where the Supreme Court of New South Wales had interfered to ensure that the prescribed process of law-making was followed, not in that instance so much by the constating instrument as by the Colonial Laws Validity Act, 1865 (Imp.). His Lordship also stated what the Board considered the real basis of the observation in Clayton v. Heffron [1960] HCA 92; (1960) 105 CLR 214, at p 235 , namely, that they were to be understood as dealing with the Court's practice in exercise of discretion and not as denying jurisdiction. "The application of a discretion to refuse relief even though this may be pursuant to a settled practice is an exercise of jurisdiction, not a denial of it" (1970) AC, at p 1155 . What was said by the Chief Justice and Justices in Osborne v. The Commonwealth [1911] HCA 19; (1911) 12 CLR 321 can, in my opinion, be accepted if confined to the provisions of the Constitution with which the Court was then dealing. In my opinion, it is not acceptable as a statement of universal application, denying the Court jurisdiction to ensure observance of the conditions of the law-making process itself. (at p454)
