"Inherent jurisdiction" is the power which a court has simply because it is a court of a particular description. Thus the Courts of Common Law without the aid of any authorizing provision had inherent jurisdiction to prevent abuse of their process and to punish for contempt. Inherent jurisdiction is not something derived by implication from statutory provisions conferring particular jurisdiction; if such a provision is to be considered as conferring more than is actually expressed that further jurisdiction is conferred by implication according to accepted standards of statutory construction and it would be inaccurate to describe it as "inherent jurisdiction", which, as the name indicates, requires no authorizing provision. Courts of unlimited jurisdiction have "inherent jurisdiction".
Inherent jurisdiction is an elusive concept and the proposition that it arises from the nature of a court has been described as metaphysical. See Yale Law Journal, vol. 57 (1947) 83, at p. 85, cited by Jacob, The Inherent Jurisdiction of the Court, Current Legal Problems, vol. 23 (1970) 23, at p. 27 . But it is undoubtedly the general responsibility of a superior court of unlimited jurisdiction for the administration of justice which gives rise to its inherent power. In the discharge of that responsibility it exercises the full plenitude of judicial power. It is in that way that the Supreme Court of New South Wales exercises an inherent jurisdiction. Although conferred by statute, its powers are identified by reference to the unlimited powers of the courts at Westminster. On the other hand, a magistrate's court is an inferior court with a limited jurisdiction which does not involve any general responsibility for the administration of justice beyond the confines of its constitution. It is unable to draw upon the well of undefined powers which is available to the Supreme Court. However, notwithstanding that its powers may be defined, every court undoubtedly possesses jurisdiction arising by implication upon the principle that a grant of power carries with it everything necessary for its exercise (ubi aliquid conceditur, conceditur et id sine quo res ipsa esse non potest). Those implied powers may in many instances serve a function similar to that served by the inherent powers exercised by a superior court but they are derived from a different source and are limited in their extent. The distinction between inherent jurisdiction and jurisdiction by implication is not always made explicit, but it is, as Menzies J. points out, fundamental.
