The relevant principles
9 There was little difference between the parties as to the general principles relevant to the identification of the nature of a "matter" for the purposes of ascertaining the existence or otherwise of federal jurisdiction.
10 The Federal Court has such original jurisdiction as is vested in it by laws made by Commonwealth Parliament: Federal Court of Australia Act 1976 (Cth) (Federal Court Act), s 19. There is a general conferral of jurisdiction in s 39B(1A)(c) of the Judiciary Act which provides that the Court has jurisdiction in any "matter" arising under a law made by the Commonwealth Parliament.
11 The expression, "matter", in s 39B(1A) is used in its Constitutional sense and has two elements. First, the "justiciability" requirement, meaning that there must be a justiciable controversy which is identifiable independently of the proceedings brought for its determination: Fencott v Muller (1983) 152 CLR 570 at 603. Second, the "subject matter" requirement, being that the subject matter, which encompasses all claims made within the scope of the controversy, must be within one of the sub-paragraphs of s 39B(1A) of the Judiciary Act: CGU Insurance Limited v Blakeley (2016) 259 CLR 339 (CGU v Blakeley) at 349 - 351 [24] - [27].
12 The justiciability requirement is to be distinguished from the legal proceeding brought to quell the dispute or to enforce the right, or the particular manner in which the cause or causes of action in the legal proceedings are framed: Re Judiciary and Navigation Acts (1921) 29 CLR 257 at 265. It is the controversy in which there exists some immediate right, duty or liability to be established by determination of the Court, and no such controversy exists where the parties are merely seeking an advisory opinion: Palmer v Ayres (2017) 259 CLR 478 at 490 - 493 [25] - [33]. This requirement is not in issue in this case.
13 The subject matter requirement of the expression "matter" is concerned with the necessary attachment of the controversy to federal law. In R v Commonwealth Court of Conciliation and Arbitration; Ex parte Barrett (1945) 70 CLR 141, Latham CJ said of this requirement (at 154):
Thus one is compelled to the conclusion that a matter may properly be said to arise under a Federal law if the right or duty in question in the matter owes its existence to Federal law or depends upon Federal law for its enforcement, whether or not the determination of the controversy involves the interpretation (or validity) of the law. In either of these cases, the matter arises under the Federal law. If a right claimed is conferred by or under a Federal statute, the claim arises under the statute.
14 The question of whether the subject matter requirement is met is not dependent upon the nature of the relief sought or whether the granting of that relief depends on federal law. For instance, where the subject of a contract is a right of property which is the creation of federal law, an action on that contract will satisfy the subject matter requirement. Thus, in LNC Industries Ltd v BMW (Australia) Ltd (1983) 151 CLR 575 (LNC Industries Ltd v BMW), the majority said (at 581):
… A claim for damages for breach or for specific performance of a contract, or a claim for relief for breach of trust, is a claim for relief of a kind which is available under State law, but if the contract or trust is in respect of a right or property which is the creation of federal law, the claim arises under federal law. The subject matter of the contract or trust in such a case exists as a result of the federal law…
15 In Oliver v Nine Network Australia Pty Ltd [2019] FCA 583 (Oliver v Nine Network), Lee J expansively articulated a number of bases on which federal jurisdiction could be attracted. His Honour referred to the passage from LNC Industries Ltd v BMW set out above and, without in any way deciding, queried whether it followed that if a respondent in any proceeding is a corporation the relevant "matter" must arise under a law of the Commonwealth Parliament because the ability of a corporation to be sued is conferred by and depends upon the Corporations Act: Corporations Act, s 124. See also Hafertepen v Network Ten Pty Limited [2020] FCA 1456 [44] where reference was made to that observation. Mr Forrest for the QBCC submitted that Lee J's observations were too wide and should not be followed. In this respect, it is not unfair to say that Mr Ivantsoff for Forward Pack did not attempt to support his Honour's obiter or did so only faintly. He submitted it was not relevant to the present case where the respondent, the QBCC, is not a corporation owing its existence to the Corporations Act.
16 However, Mr Forrest's submissions were not directed solely to the proposition that if at any time a company was a respondent to a proceeding it must be within the jurisdiction of the Court. His submissions were to the effect that the reasoning process by which Lee J's particular introspection was reached was in error. Specifically, he submitted that the essence of the above passage in LNC Industries Ltd v BMW from which Lee J drew his observations actually requires attention be focused on the "right or duty in question in the matter" and whether it "owes its existence to federal law or depends on federal law for its enforcement". In Oliver v Nine Network, the existence of the company and its powers were irrelevant to the right or duty in question. The proceedings involved an action for defamation in which the question of the Court's jurisdiction arose consequent upon the fact that the broadcast in question had only occurred in New South Wales. Despite that, an allegation which had been made in the statement of claim was that the broadcast had been Australia-wide and his Honour held this sufficiently attracted jurisdiction even though not ultimately made out: Burgundy Royale Investments Pty Ltd v Westpac Banking Corporation (1987) 18 FCR 212 at 219; Allsop J, "Federal jurisdiction and the jurisdiction of the Federal Court of Australia in 2002" (2002) 23 Aust Bar Rev 29 at 45. Although Lee J's catechism on the scope of the Court's jurisdiction is both erudite and illuminating, the issues before his Honour did not necessitate the making of any determination as to whether jurisdiction was attracted merely by reason of the respondent being a corporation. In any event, I accept Mr Forrest's submission that the right or duty in question in that case, being the defaming of the applicant by the respondent and the subsequent suffering of damage, did not relevantly owe its existence to the status of the defendant company as a corporation. Whilst it is true that the status of the corporate entity was necessary in order for it to be sued, that was merely part of the context in which the right, duty or liability arose. However, neither the right, duty nor liability "in question in the matter" owed their existence to the company's status. The importance of this discussion is that it emphasises that attention must be focused on the relevant "controversy" in question rather than on the characteristics of the parties to it or the matrix of surrounding facts in which it arose. This was made explicit in CGU Insurance Limited v Blakeley, where the majority opined (at 349 [24]) that, "Jurisdiction with respect to a particular subject matter is authority to adjudicate upon a class of questions concerning that subject matter". Where no question arises as to the corporate existence of a defendant, there is no relevant federal subject matter requiring an adjudication. If, however, an issue in the controversy was a purported company's entitlement to sue by reason of a question concerning its corporate status, different issues would arise.
17 In this context, it is apt to recall the observations of the High Court in Crouch v Commissioner for Railways (1985) 159 CLR 22 at 37 that the concept of the expression "matter" as used in the Judiciary Act and the Constitution focuses attention on the substance of the dispute between the parties and denotes in wide terms the types of controversies which might come before a Court of Justice. Further, it is used in s 75(iv) of the Constitution to refer to matters between designated parties and that tends to suggest that it is the dispute rather than the parties' characteristics which is critical. The same focus on the essentiality of the disputation or controversy can be seen in the comments of Anderson J in RNB Equities Pty Ltd v Credit Suisse Investment Services (Australia) Ltd (2019) 370 ALR 88 (RNB Equities) at 94 - 95 [19]:
The essential question under this provision (as it would be under s 39B(1A)(c) of the Judiciary Act) is whether the matter may be characterised as "arising under" the relevant federal law. A matter arises under federal law if that law is the source of the relevant right or duty, or if that law created the relevant subject matter, or if federal law provides the authority for enforcing the right or duty, or if the matter's resolution turns on the federal law's interpretation.

18 Similarly, in Rana v Google Inc (2017) 254 FCR 1, the Full Court (Allsop CJ, Besanko and White JJ) identified a variety of ways in which a matter may arise under a law of the Commonwealth Parliament as follows (at 5 - 6 [18]):
A matter will "arise under" a law of the Parliament in a number of ways. These include cases where a cause of action is created by a Commonwealth statute; where a Commonwealth statute is relied upon as establishing a right to be vindicated; where a Commonwealth statute is the source of a defence that is asserted; where the subject matter of the controversy owes its existence to Commonwealth legislation - that is where the claim is in respect of or over a right which owes its existence to federal law; where it is necessary to decide whether a right or duty based on a Commonwealth statute exists even where that has not been pleaded by the parties, or where a federal issue is raised on the pleadings but it is unnecessary to decide: …
19 The common thread which runs through the several examples is that the rights, duties, or subject matter with which the controversy is concerned have their origin in or owe their existence to a law of the Commonwealth. It is, perhaps, not insignificant that their Honours did not extend the categories to cases where the existence of one or more of the parties was founded upon a relevant law even if that issue was not relevantly in dispute.
20 The circumstances of this case also raise the issue of whether the whole of the proceeding is within the Court's jurisdiction because the overall controversy involves federal and non-federal claims. The ascertainment of whether a non-federal claim is or is not part of a larger matter is not without its difficulties. The determination of that question in any particular circumstance is assisted by those cases which consider the issue of so-called "accrued jurisdiction". In these, the question is whether a claim, which by itself would not be within the Court's jurisdiction, is brought within it because it is part of a "matter" which includes a claim arising under federal law. This was addressed in Re Wakim; Ex parte McNally (1999) 198 CLR 511 (Re Wakim). In the reasons of Gummow and Hayne JJ, their Honours observed that the question of what constitutes a single controversy "depends on what the parties have done, the relationships between or among them and the laws which attach rights or liabilities to their conduct and relationships": at 585 - 586 [140] quoting Fencott v Muller at 607. In that respect, their Honours continued (at 585 - 586 [140] - [141]):
140. … There is but a single matter if different claims arise out of "common transactions and facts" or "a common substratum of facts" notwithstanding that the facts upon which the claims depend "do not wholly coincide". So, too, there is but one matter where different claims are so related that the determination of one is essential to the determination of the other, as, for example, in the case of third party proceedings or where there are alternative claims for the same damage and the determination of one will either render the other otiose or necessitate its determination. Conversely, claims which are "completely disparate", "completely separate and distinct" or "distinct and unrelated" are not part of the same matter.
141. Often, the conclusion that, if proceedings were tried in different courts, there could be conflicting findings made on one or more issues common to the two proceedings will indicate that there is a single matter. By contrast, if the several proceedings could not have been joined in one proceeding, it is difficult to see that they could be said to constitute a single matter.
(Citations omitted).
21 Previously, in Fencott v Muller, a majority of the High Court had identified the concept of "common transactions and facts" as the touchstone which connects claims or causes of action within the scope of a single matter. In the application of that concept, it was said (at 607 - 608):
… it must result in leaving outside the ambit of a matter a "completely disparate claim constituting in substance a separate proceeding", a non-federal matter which is "completely separate and distinct from the matter which attracted federal jurisdiction" or "some distinct and unrelated non-federal claim".
(Citations omitted).
22 The proper application of these tests is not achieved merely by reference to the proceedings which are instituted by the parties in respect of the controversy, although they can be illuminated by the conduct of such proceedings and the issues raised. In the end, it is a matter of impression and of practical judgment whether the federal and non-federal claims joined in the one proceeding are within the ambit of the same matter: Fencott v Muller at 608.
23 In RNB Equities, Anderson J, after a careful and thoughtful analysis of the authorities, observed (at 98 [30]):
The above authorities make clear that this Court will have jurisdiction to hear and determine a claim, even though it raises no federal law claim, if it shares a "common substratum of facts" with a federal law claim.
24 Those comments provide a useful and accurate guide to the practical application of the tests which his Honour had referenced. I might only add that it is apparent his Honour intended the word "shares" to mean that the several causes of action have a suitable degree of commonality in their respective substratum of facts and there is no requirement that they be identical.
