Res judicata
18 The fact that the application for review was dismissed by consent, is not a bar to the Minister being able to raise a claim of res judicata. An order made, or a judgment given, by consent binds the parties to the judgment or order as effectively as if the judgment had been given, or the order made, after a fully contested hearing: Re South American & Mexican Co; Ex parte Bank of England [1895] 1 Ch 37 at 45; Spencer Bower, Turner & Handley, The Doctrine of Res Judicata (3rd edn, Butterworths, London, 1996) at pars [38]‑[40]. The only difficulty that can arise in determining whether a consent order raises an issue of res judicata, is in specifying the "res", or the matter, or the cause of action which has already been determined by the Court: Chamberlain v Deputy Commission of Taxation (1988) 164 CLR 502.
19 In Somanader v Minister for Immigration & Multicultural Affairs (2000) 178 ALR 677, Merkel J held that dismissal by consent of proceedings brought under Pt 8 of the Act gave rise to a res judicata in respect of a later proceeding. In the present case, the cause of action relied upon by the applicant is an attack upon the decision of the Tribunal. An attack was also made upon the decision of the Tribunal in the proceeding before North J the subject of the consent dismissal. However, in the proceeding before North J, the cause of action arose under Pt 8 of the Act (in the form in which the Act then existed), whereas the cause of action in the matter presently before the Court arises under s 75(v) of the Constitution of the Commonwealth of Australia (1901 (Cth) ("the Constitution").
20 The cause of action in the proceeding which was the subject of the consent dismissal was one which alleged errors of law within s 476(1)(e) of the Act as it then existed. The cause of action relied upon in the present proceeding is one based upon the Tribunal having committed an error of law. I adopt with respect, and apply to the present circumstances, the observations of Merkel J in Somanader v Minister for Immigration & Multicultural Affairs (supra) at [65] where his Honour said:
"The substratum of facts giving rise to the right to review are exactly the same. The factual circumstances relied upon to establish the right to relief are the same. The substance of the two proceedings is the same. The right to relief in each case is informed by the same substantive law principles. It is not contended that the parties to the two sets of proceedings differ in any material respect. Thus, the dismissal orders finally determined the issue of whether the RRT committed an error amounting to a constructive failure to exercise jurisdiction or an error of law in the interpretation and application of the Convention in the present case."
21 Although the cause of action relied upon in the present case arises under s 75(v) of the Constitution, whereas the proceeding before North J arose under Pt 8 of the Act, it should be noted that s 75(v) of the Constitution is not a cause of action in itself but rather a source of federal jurisdiction: see Somanader at [59]‑[62].
22 The applicant submitted that the cause of action in each of the two proceedings is not the same, as a matter of substance. The applicant submitted that the present application sought review on the ground that the Tribunal failed to deal with a particular claim made by the applicant or failed to take into account relevant considerations, whereas the earlier proceeding claimed that the Tribunal had misconstrued and misapplied the law relevant to the particular issues before it. In other words, the applicant submitted that he had previously sought review for an error of law but now his claim is the Tribunal's failure to deal with a particular issue. However, both matters result in a cause of action based upon an error of law and as such the requisite commonality between the two causes of action exists.
23 In the proceeding before North J the applicant raised, as a cause of action under s 476(1)(e) of the Act, the ground that the Tribunal made an error of law. The particulars relied upon under that ground included the allegation that the Tribunal adopted the course of relying on the decision‑maker's impressions and "interpreted the facts as to how the Applicant should have behaved rather than considering the total claims of the applicant". The present cause of action relies upon a failure by the Tribunal to consider or address a particular claim. Such a cause of action falls within the ambit of the claim made under s 476(1)(e) in the earlier proceeding. Accordingly, the Minister's claim that the matter before the Court is res judicata is made out.
