It must be accepted that Ch. III imposes limits on the delegation of powers and functions conferred on a court. If all such powers were, as a result of delegation, to be regularly exercised by persons not constituting the court, the powers (other than those which are essentially and, thus, exclusively judicial) would cease to fall within the concept of judicial power and the body on whom they were conferred would no longer properly be described as a court. However, in my view, the question is not whether the Act purports to authorize delegation beyond such limits but whether there has been an attempt in O. 36A, r. 2(1)(n) by the Family Court to delegate beyond those limits. The specific legislative powers conferred by ss. 73, 76, 77, 78 and 79, even when aided by s. 51(xxxix), touch the question of delegation only indirectly. Pursuant to the power conferred by s. 79, the Parliament may prescribe the number of judges necessary to exercise federal jurisdiction or some particular part thereof and, by a law of that nature, the Parliament can preclude the delegation of the power or powers associated with the exercise of that jurisdiction. Again, pursuant to s. 51(xxxix), the Parliament might prescribe rules of practice or procedure which would have the effect of precluding the delegation of some particular power. But to say that Parliament may preclude delegation is not to say that its authorization is necessary before a particular power or function may be delegated. Rather, the specific and limited legislative powers in ss. 73, 76, 77, 78 and 79 point to the conclusion that, unless the contrary is required by a law made pursuant to s. 79 or s. 51(xxxix), a federal court may, within the limits imposed by Ch. III and within the limits of what is practicable, determine for itself whether, and, if so, to whom and on what terms, particular powers and functions should be delegated. A law, such as s. 37A of the Act, which purports to authorize the delegation of particular powers and functions and specifies to whom and on what terms they may be delegated is thus to be seen as a law requiring that the powers and functions be performed by the court constituted by one or more of its judges as required by its constituting Act unless delegated in accordance with its provisions. As such, s. 37A(1) is a law validly enacted pursuant to s. 79 of the Constitution.
