To be precise, jurisdiction is conferred on the Federal Court by s. 86 to hear and determine only those matters arising under the Trade Practices Act which answer the description of "actions, prosecutions and other proceedings under this Part", viz. Pt VI. There is no provision in the Act which confers jurisdiction on the Federal Court in matters arising under Pt IV or Pt V as such, and it has rightly been held that matters arising under those Parts, and not also arising under Pt VI, are within the jurisdiction of the State courts
This passage either accords or is not inconsistent with the judgments delivered in that case by the other members of the Court (except possibly Murphy J.). Mason, Brennan and Deane JJ., after a review of the authorities, said that the first limb of s. 86 "confers jurisdiction on the Federal Court to determine the non-federal aspects of a single justiciable controversy of which the issues raised under the Act form an integral part" [7] . Their Honours continued:
There are two constituent elements in the jurisdiction which is thereby conferred: the first element comprises the federal issues which arise for determination under the federal law, e.g., the issues which arise in these cases under ss. 52, 53(aa) and 53A of the Act and damages for contravention; the second element comprises the non-federal issues, the suggestion here being that the issues arising in the actions for specific performance in the Supreme Court are non-federal aspects of a single controversy of which the federal issues form an integral part. For want of a better term it is convenient to refer to this second element as "accrued jurisdiction".
They went on to consider the extent to which jurisdiction is made exclusive by s. 86 and concluded that the reference in s. 86 to "jurisdiction" which is made exclusive should be read as a reference to the jurisdiction conferred, other than to accrued jurisdiction [8] ; in other words, the second limb of s. 86 does not make the accrued jurisdiction of the Federal Court exclusive. It clearly appears from this judgment, and is indeed obvious, that there can be no accrued jurisdiction unless there are federal issues which that Court has jurisdiction to entertain. Wilson and Dawson JJ., consistently with this view, said [9] :
The jurisdiction of the Federal Court which is made exclusive is the hearing and determination of claims for the penalties or relief for which Pt VI provides.
