"A State court receives State jurisdiction under the constitution and laws of that State. It may also be invested with federal jurisdiction by a law made by the Parliament under s 77(iii) of the Constitution; s 39(2) of the Judiciary Act 1903 (Cth) is an example of such a law. The federal courts established by the Parliament, the Federal Court of Australia, the Family Court of Australia and the Federal Magistrates Court, exercise their jurisdiction, necessarily federal, by reason of its conferral by laws enacted under s 77(i) of the Constitution. A 'matter' in respect of which that jurisdiction is conferred may, in a given case, include claims arising under common law or under the statute law of a State. But the jurisdiction invoked remains, in respect of all of the claims made in the matter, 'wholly' federal; even in a State court 'there is no room for the exercise of a State jurisdiction which apart from any operation of the Judiciary Act the State court would have had' and 'there is no State jurisdiction capable of concurrent exercise with the federal jurisdiction invested in the State court'. These terms were used by Barwick CJ in Felton v Mulligan." (footnotes omitted)
