Res judicata and Anshun estoppel
21 The taxpayers claim that the second summary judgment application was barred by both res judicata and Anshun estoppel.
22 The reference to Anshun estoppel is somewhat misdirected in light of the taxpayers' failure to distinguish such claim from res judicata. Although Anshun estoppel is sometimes described as an extension of the res judicata doctrine (see Champerslife Pty Ltd v Manojlovski (2010) 75 NSWLR 245 at [39]), there is a subtle difference in the effect of the claims. Anshun estoppel is founded on the reasonableness of the conduct of a litigant, or another person, in relation to earlier proceedings: see Meriton Apartments Pty Ltd v Industrial Court of New South Wales (2009) 263 ALR 556 at [60]; and Champerslife Pty Ltd at [39]. As was stated by Gibbs CJ and Mason and Aickin JJ in Port of Melbourne Authority v Anshun Proprietary Limited (1981) 147 CLR 589 at 602-603 ('Anshun'):
…there will be no estoppel unless it appears that the matter relied upon… in the second action was so relevant to the subject matter of the first action that it would have been unreasonable not to have relied on it.
23 In contrast, Fullagar J in dissent in Jackson v Goldsmith (1950) 81 CLR 446 at 466 expressed the contrasting rule of res judicata as:
… where an action has been brought and judgment has been entered in that action, no other proceedings can thereafter be maintained on the same cause of action. This rule is not, to my mind, correctly classified under the heading of estoppel at all. It is a broad rule of public policy based on the principles expressed in the maxims "interest reipublicae ut sit finis litium" and "nemo debet bis vexari pro eadem causa."
24 His Honour's statement has subsequently been cited with approval in Anshun at 597 and Chamberlain v Deputy Federal Commissioner of Taxation (1988) 164 CLR 502 ('Chamberlain') at 507-08.
25 The applicants' submissions in support of leave listed at [17] above do not raise any claim that the Deputy Commissioner relied on a matter in Berhad No 4 that he did not rely upon in the proceedings before Kenny J in 2010. To the extent that the taxpayers seek to rely on a defence of Anshun estoppel on appeal, such defence has no prospects of success.
26 With respect to res judicata, the taxpayers submit that any issue as to their liability for GIC was exhausted by the decisions of Kenny J and therefore finally determined in 2010. The taxpayers accordingly submit that an application for summary judgment by the Deputy Commissioner that relies on item 4 does not give rise to a fresh cause of action. This submission relies upon the principles in Patterson v Richards [1963] VR 179, namely that a cause of action is constituted not by the law applicable to the action, but by the facts giving rise to relief.
27 The taxpayers' argument is predicated upon the issue of GIC liability being finally determined prior to Berhad No 4. To determine whether there are reasonable prospects of this proposition being correct, it is essential to have regard to the effect of the decisions of Perram J in both Berhad No 3 and Berhad No 4.
28 When the proceedings came before Perram J in Berhad No 3, the taxpayers' application to vary the judgments of Kenny J in respect of the alleged GIC liability was opposed by the Deputy Commissioner. Following the submissions of counsel for both the taxpayers and the Deputy Commissioner, his Honour said:
If this judgment was set aside, then the merger of rights which has presently happened between the general interest charge as levied and the judgments, would be undone.
29 Counsel for the Deputy Commissioner concurred with his Honour's observation and stated that in such event the Deputy Commissioner would move immediately to seek GIC under item 4. The following exchange then occurred between his Honour and counsel for the taxpayers:
MS SEIDEN: Certainly not, no. also, the question of what GIC the commissioner is actually going to try to seek on entering the judgment, to the extend [sic] that he considers he is entitled to GIC after the judgment date, the taxpayers would submit that, well, the tax debt itself has now merged into the judgment, and the commissioner no longer has all those provision about GIC. So until we actually see the application that the commissioner intends to make - - -
HIS HONOUR: Well, they're currently merged in the summary judgment.
MS SEIDEN: Indeed.
HIS HONOUR: If the summary judgment is set aside, they will be un-merged.
MS SEIDEN: That's right.
HIS HONOUR: They never were merged, if that happens.
MS SEIDEN: That's right. But until we see exactly what it is that the commissioner proposes, it's impossible for the taxpayers to say exactly what they would do…
30 This is a clear statement by his Honour that if the summary judgments of Kenny J were set aside, the rights which may have merged in the decision would no longer be merged. The taxpayers' counsel accepted that position. The making of the orders on 26 June 2012 in VID672/2010, VID887/2010 and VID888/2010 achieved that very result. It was then open to the Deputy Commissioner to file an application for summary judgment for payment of the GIC based upon his statutory entitlement under item 4.
31 It follows that from the moment the GIC issue was excised from the judgments of Kenny J by virtue of Berhad No 3, there was no final decision in relation to the GIC aspect of the Deputy Commissioner's claim.
32 The present circumstances may be contrasted with the decisions of Anshun and Chamberlain. In Anshun, Brennan J at 608 said:
Unless a judgment recovered after litigation between parties is reversed or set aside, it binds the parties and determines their rights and liabilities inter se according to its tenor (Livesey v. Harding [1855] EngR 875; (1855) 21 Beav 227 (52 ER 846); Peareth v. Marriott (1882) LR 22 Ch D 182; Thompson v. Thompson (1923) 2 Ch 205, at p 214; Badar Bee v. Habib Merican Noordin (1909) AC 615 ). "It is most clear", said Lord Mansfield in Moses v. Macferlan (1760) 2 Burrell 1005, at p 1009 [1760] EngR 713; (97 ER 676, at p 678), "that the merits of a judgment can never be over-haled by an original suit, either at law or in equity. Till the judgment is set aside, or reversed, it is conclusive, as to the subject matter of it, to all intents and purposes."
33 In the absence of there being an existing judgment, the doctrine cannot apply to any subsequent judgment that might bear upon the subject matter. The same observation was made by the High Court of Australia in Chamberlain v Deputy Commissioner of Taxation at 511, Deane, Toohey and Gaudron JJ said:
So long as the respondent chooses, as he does, to take no step to set aside the judgment and to raise no issue in the second action as to the circumstances in which that judgment was obtained, he must accept the consequences of res judicata.
34 The Deputy Commissioner in Chamberlain sought to proceed on a cause of action in respect of which he had already received judgment (for a much smaller sum) and then, as explained by Deane, Toohey and Gaudron JJ at 511, 'without seeking to have that judgment set aside or otherwise to impugn it on the ground that it had been entered or obtained by mistake, sought to sue again in respect of the same cause of action'. In these circumstances, the doctrine of res judicata clearly applied.
35 The situation in the present proceedings is the converse to that considered in Chamberlain. The effect of Berhad No 3 was to delete from the judgments of Kenny J the components of GIC. From that time, until summary judgment for GIC was entered in Berhad No 4, there was no extant judgment pertaining to GIC. Therefore the taxpayers' argument that the second summary judgment application was barred by reason of res judicata has no reasonable prospects of success. It follows that the decision of his Honour in Berhad No 4 is not attended with sufficient doubt to warrant its being reconsidered by the Full Court.
