The only express power in the Commonwealth Constitution for the Commonwealth Parliament to legislate in relation to State courts is sub-s 77(iii)[9] - which is in Ch. III - which permits the Commonwealth Parliament to invest State courts with federal jurisdiction. Further, there is a general implied prohibition upon Commonwealth legislation which is inconsistent with "the continued existence of the States as independent entities and their capacity to function as such", a matter "which directs attention to aspects of a State's functions which are critical to its capacity to function as a government": Re Australian Education Union, ex parte Victoria (1995) 184 C.L.R. 188, 231-232; Victoria v. The Commonwealth (4 September 1996, joint judgment, at pp. 31-32). State courts are, of course, a fundamental organ of State government, and it is at least consistent with the general constitutional prohibition to which reference has been made that the Commonwealth Parliament's power to legislate to confer federal jurisdiction on State courts is subject to limitations;[10] for example, jurisdiction can be vested only with respect to matters enumerated in ss. 75 and 76 of the Constitution (R. v. Murphy [1985] HCA 50; (1985) 158 C.L.R. 596, 613), and only judicial functions can be conferred (Queen Victoria Memorial Hospital v. Thornton [1953] HCA 11; (1953) 87 C.L.R. 144; Murphy at pp. 613-614; Kable per Gummow J.). Further, although it may prescribe the number of judges to exercise federal jurisdiction (Constitution, s. 79), the Commonwealth can only vest federal jurisdiction in a State court as it finds it, in the sense that it cannot affect its structure or constitution or the organisation through which its powers and jurisdiction are exercised: Federated Sawmilling Timberyard & General Woodworkers' Employees' Association (Adelaide Branch) v. Alexander ; , 313; Le Mesurier v. Connor ; at pp. 495-497, 498; Adams v. Chas. S. Watson Pty Ltd ; , 554-555; Peacock at p. 37; Kotsis v. Kotsis ; ,109-110; Russell at pp. 516-517, 530, 535, 554; Hospital Contribution Fund at p. 61; Brown v. R. ; , at pp. 198-199, 206-207, 218-219; Harris 92, 107, 117, 137-138, 145-146, 158; Leeth at pp. 455, 468-469; Kable. However, the Commonwealth Parliament may determine the nature and limits of the federal jurisdiction to be exercised (Adams) and the practice and procedure to be observed in exercising federal jurisdiction (Russell at pp. 518-519, 535-536, 544-545; Brown at pp. 198-199 and cases cited; Kable).
