26 The appellants also submitted that:
(a) pursuant to the principle in Cell Tech Communications Pty Ltd v Nokia Mobile Phones (UK) Limited & Ors (1995) 58 FCR 365 (per Lindgren J), the facility to challenge jurisdiction without entering an appearance, as with rules in relation to the entry of a conditional appearance in other jurisdictions:
... make[s] it clear that the focus of concern is the invoking by an applicant of the Court's coercive power to grant the relief sought in the application. The question raised is whether a respondent should be subjected to that power by nothing more than the filing and service of an application.
(b) pursuant to r 82, there is a right to have the question of jurisdiction determined before the hearing of substantive issues. This right is rendered nugatory if, as Staunton J contemplated, the hearing of the motions could be adjourned to final hearing and the appellants are directed to file an appearance, thereby submitting to jurisdiction.
(c) further, in the absence of an appearance being filed, under r 76 a respondent was not entitled to file a defence without being granted leave to do so. Consequently, her Honour's decision required the appellants either to submit to jurisdiction in circumstances where they have actively sought to challenge that jurisdiction in accordance with the Court's rules, or face a default judgment. Ultimately, her Honour had determined the appellants' objection to jurisdiction without hearing it.
(d) as to the nature of proceedings under s 106 generally, the appellants submitted that such proceedings have been characterised as non-judicial in the sense that they are about the creation of rights rather than the determination of existing rights: Mullins v Peoplebank Australia Pty Limited [2003] NSWIRComm 457. Further, the fact that in the course of reaching an arbitral determination the Court must form opinions on matters of law does not convert the proceedings to judicial proceedings: Re Cram; Ex parte Newcastle Wallsend Coal Co Pty Ltd (1987) 163 CLR 140 at 149. In any event, the question of whether the proceedings are judicial or arbitral is open to debate: Taudevin v Egis Consulting Australia Pty Limited (No 1) .
(e) the Court was bound by the decision of the High Court in Re Dingjan; ex parte Wagner (1995) 183 CLR 323 where it was held that the power conferred on the Court Session pursuant to s 106 was non-judicial. The appellants referred to the consideration that because a tribunal possesses certain procedural powers enjoyed by courts, is authorised to determine questions of law arising before it, and is constituted by a judge, does not necessarily mean that the tribunal is exercising judicial power: Drake v Minister for Immigration and Ethnic Affairs (1979) 46 FLR 409 at 414.
(f) insofar as a tribunal is a federal tribunal, it is clear that it cannot exercise judicial power unless it is established under the Constitution and its jurisdiction respects the separation of powers which is constitutionally guaranteed: R v Kirby; ex parte Boilermakers' Society of Australia (1956) 94 CLR 254. Of course, that is not to say that in a system of State jurisprudence, a Court might not have allocated to it non-judicial functions.
(g) nevertheless, the question of whether a court in which federal jurisdiction is reposed may continue to exercise non-judicial power simultaneously has not been previously considered, notwithstanding the conclusions of the Full Bench in Taudevin v Egis Consulting Australia Pty Limited (No 1) .
(h) a State court which is entrusted with federal judicial power cannot have reposed in it any power or function antithetical to the exercise of federal judicial power: Kable v The Director of Public Prosecutions for the State of New South Wales (1996) 189 CLR 51.
(i) while the State legislature, unrestricted by the doctrine of the separation of powers, may confer non-judicial powers on a court and need not have recourse to the principles of persona designata (even if the court exercises federal jurisdiction, provided the exercise of the non-judicial power is not incompatible with the exercise of federal judicial power), it nonetheless remains the case that the exercise of non-judicial power must be detached from the exercise of federal judicial power.
