5. The right to registration of a trade mark depends upon the fulfilment of a number of objective conditions which the Act prescribes both positively and negatively. It is enough to mention the definition of "trade mark" in s. 4, the essential particulars referred to in ss. 15 and 16, and the disqualifications referred to in s. 25 and in s. 114. The statute might have drawn a clear distinction between on the one hand the administrative decision to give effect to an opposition and refuse registration or to overrule an opposition and grant registration and on the other hand a jurisdiction conferred upon the Court to entertain a challenge to the administrative decision and determine judicially that the title to registration did or did not exist and to do so by a binding and enforceable decree. If that had been done no difficulty could be found in treating the provision conferring such a jurisdiction upon the Court as a valid exercise of the legislative power conferred by s. 76 (ii) or s. 77 (iii) as the case might be. It would have been but another instance of the kind of thing done by Div. 2 of Pt. V of the Income Tax and Social Services Contribution Assessment Act 1936-1957. Cf. Steele v. Defence Forces Retirement Benefits Board [1955] HCA 34; (1955) 92 CLR 177, at pp 186, 187 ; The Commonwealth v. Anderson [1957] HCA 44; (1957) 97 CLR 345 ; Federal Commissioner of Taxation v. Munro [1926] HCA 58; (1926) 38 CLR 153 . But the distinction was not maintained in the language which the legislature adopted with reference to the registrar, the Law Officer and the Court in ss. 42 to 45. This is also true with respect to appeals from a refusal to accept an application which are dealt with by ss. 34 and 35. In other words, the contention advanced before us is to be attributed to the use by the legislature of the same or similar terms in describing the administrative power which ss. 42 and 43 purport to confer and the judicial power which ss. 44 and 45 purport to confer. It is not surprising that similarity of expression has given rise to the argument that one or other provision must be bad; and since it is not assumed that judicial power has been conferred on administrative officers the contention is that the truth must be that it was intended to confer an administrative power on the Court. In support of this latter view it is contended that s. 44 does not intend to give a power the exercise of which is definite. It is suggested that although on an appeal by an applicant or an opponent the Court is to determine whether the application ought to be refused or ought to be granted the decision of the Court is not necessarily binding and there is nothing to enforce a decision in favour of the grant of registration or for that matter a decision in favour of the refusal of registration. This argument does not appear to be well founded. Section 47 should probably be construed as imposing upon the registrar an imperative duty to register when the Court has decided against an opposition. It is true that in s. 47 the words "unless otherwise prescribed by the regulations" may seem to qualify the duty but these words appear to affect only the date to be given to the registration. A regulation did exist which assumed that these words bore a wider interpretation. It is now repealed. It was reg. 38 of the Trade Marks Regulations 1913-1950. As it is repealed little need be said about it. A comparison of the regulation with s. 47, however, should be enough to show that it exceeded any power that s. 47 could confer. Apart from s. 47 there is a clear implication in s. 44 that the exercise of the judicial power that provision purports to confer shall be conclusive upon the registrar as well as upon the parties. The determination of the Court that the application should be refused necessarily means that the application is at an end. In the same way a determination of the Court that the application ought to be granted leaves nothing but the administrative steps necessary to express a grant. (at p659)
