CONSIDERATION
37 It is not necessary to say a great deal about the first ground of appeal.
38 That is because the respondent accepts, in the light of the written submissions made by the appellant, that the primary judge should not have dismissed the claim on that ground.
39 It is, of course, incumbent upon the Court to be satisfied that arguable error is demonstrated on the part of the primary judge: Bradken Ltd v Norcast S.ár.L (2013) 219 FCR 101; [2013] FCAFC 123; Telstra Corporation Ltd v Minister for Broadband, Communications and the Digital Economy (2008) 166 FCR 64; Commonwealth Bank of Australia v Walker (2012) 289 ALR 674. In our view, it is arguable that the primary judge erred in striking out the claim as an abuse of process, as acknowledged by the respondent through counsel. The short point is that the statement of claim in this Court extended beyond the claim pleaded in the WA claim against Suda solely in contract, namely to include pleas based upon restitution or unjust enrichment. It also included the claims concerning the conduct leading to, and maintaining, the retainer. It is fair to say that those claims were not well expressed, and to acknowledge (as does the respondent) that the full understanding of the scope of the appellant's claims in his statement of claim is assisted by counsel now appearing for the appellant. They have given a much clearer focus to his statement of claim than, it appears, the appellant was able to do at first instance. It is not necessary for this purpose to refer in detail to the statement of claim. It is further considered when considering the second ground of appeal.
40 We observe that, as the primary judge said, the pleading against Suda in the WA claim was solely a contractual one. However, we consider (as the respondent accepts) that it was arguably erroneous to categorise all the appellant's claims against the respondent as depending on him establishing in the proceeding in this Court that there was an enforceable promise made by Suda to the appellant. The statement of claim in the proceeding in this Court arguably accommodates the assertion that his claim against the respondent is because there was no advice given about, and were no claims made in, the WA claim for unjust enrichment or for restitution or for a form of quantum merit. It also appears to make the statutory claim under s 18 of the ACL that the respondent, at the time of her engagement, misrepresented her professional capacity to take proper instructions and to conduct appropriately the claim then proposed against Suda, including giving proper advice about the alternative bases on which such a claim might be pursued.
41 Accordingly, the focus of submissions on the appeal was directed to whether it was correct for the primary judge to have summarily dismissed the claim based upon advocate's immunity. That exposed three issues:
(1) whether the doctrine of advocate's immunity applies to enable a claim such as that of the appellant to be dismissed summarily, where there had been no trial and so no final determination after a hearing on the merits of the claim against Suda;
(2) whether it is erroneous in any event to apply the doctrine of advocate's immunity to the present claim as expressed in the statement of claim so as to lead to the summary dismissal of the claim; and
(3) whether the doctrine of advocate's immunity applies to protect the advocate from statutory causes of action, relevantly for contravention of s 18 and potentially ss 20 and 21 of the ACL.
42 In each instance, the appellant contended that the law is not sufficiently settled to have justified the summary dismissal of the claim, and in the case of issue (2) it was argued that it was not sufficiently clear in the light of the allegations in the statement of claim that the claim should have been summarily dismissed.
43 It is helpful first to review the two leading High Court cases.
44 The first in time is Giannarelli.
45 Giannarelli decided that, at common law, an advocate cannot be sued for negligence in the conduct of a case in court, in the absence of any contrary statutory prescription. That case alleged negligence on the part of several barristers in failing to advise that evidence given to a Royal Commission was not admissible on a charge of perjury, and in not objecting to that evidence. It is not necessary to refer to the views of the Court on the collateral or related issues as to the effect of s 10(2) of the Legal Profession Practice Act 1958 (Vic) nor as to the immunity extending to a solicitor when acting as an advocate.
46 The recognition of advocate's immunity was accepted by Mason CJ, Wilson, Brennan and Dawson JJ, each in separate judgments. The minority view of Deane, Toohey and Gaudron JJ was that the legislation had removed the immunity.
47 Mason CJ at 555-559 explained the public policy underlying advocate's immunity, as it extends to those engaged in the administration of justice. His Honour at 559 then discussed where the dividing line is to be drawn between providing immunity for "in-court negligence" and "work done out of court", as the public policy considerations underlying the immunity have no relevance to negligent advice in relation to out-of-court matters. He said:
Is the immunity to end at the courtroom door so that the protection does not extend to preparatory activities such as the drawing and settling of pleadings and the giving of advice on evidence? To limit the immunity in this way would be to confine it to conduct and management of the case in the courtroom, thereby protecting the advocate in respect of his tactical handling of the proceedings. However, it would be artificial in the extreme to draw the line at the courtroom door. Preparation of a case out of court cannot be divorced from presentation in court. The two are inextricably interwoven so that the immunity must extend to work done out of court which leads to a decision affecting the conduct of the case in court. But to take the immunity any further would entail a risk of taking the protection beyond the boundaries of the public policy considerations which sustain the immunity. I would agree with McCarthy P in Rees v Sinclair (41) where his Honour said:
"... the protection exists only where the particular work is so intimately connected with the conduct of the cause in Court that it can fairly be said to be a preliminary decision affecting the way that cause is to be conducted when it comes to a hearing."
This persuasive statement of the limits of the immunity was indorsed by four members of the House of Lords in Saif Ali (42). The statement is all the more important in that it acknowledges the existence and the limits of the immunity in a country where the legal profession is fused.
That approach was then applied to the particular facts. Mason CJ at 558 said that the public policy in not allowing Court decisions to become the subject of collateral attack by actions against counsel for in-court negligence was one of the two significant aspects of public policy.
48 Wilson J at 576-576 addressed the public policy supporting the common law rule of advocate's immunity. It is fair to observe that his Honour's focus on the public interest in the due administration of justice identified five distinct grounds to support the immunity, including difficulties associated with re-litigation where the claim has "a view to proving that the original decision was wrong by reason of counsel's negligence" (at 573). In the view of Wilson J, public confidence in the administration of justice by preserving finality of litigation was most at risk in the circumstances of that case. It supported the dismissal of the appeal.
49 Brennan J generally agreed with the judgment of Mason CJ (see at 579). His Honour there said the immunity extended to "the making of preliminary decisions affecting the way in which the case is to be conducted when it comes to a hearing". That, in the circumstances, meant the appeal was to be dismissed.
50 Dawson J at 594-596 reached views generally consistent with those already referred to. The question of where to draw the line was not specifically adverted to, clearly because in his Honour's view clearly the circumstances fell within the immunity. At 594-595, his Honour (as did Wilson J) placed considerable emphasis on avoiding the decision of a court being subject to collateral attack by a client seeking to blame the advocate for the loss of the case.
51 The more recent is D'Orta-Ekenaike.
52 That case concerned a claim against Victoria Legal Aid, but in substance against a solicitor and against a barrister, for negligence in relation to a charge of rape. The appellant in that case first pleaded guilty, on legal advice, and having changed his plea was eventually acquitted. It was claimed that the first plea of guilty was induced by inappropriate pressure and included advice about the likely sentence if he then pleaded guilty, and alternatively if he pleaded not guilty but was convicted. The occasion when the relevant advice was given was immediately before the commencement of the committal hearing, at which the plea of guilty was made. The immediately relevant passage in the plurality judgment is set out at [30] above. The allegedly wrongful advice did not ultimately affect the outcome, as the appellant was acquitted. He complained of the adverse intermediate consequences.
53 The plurality in D'Orta-Ekenaike at [88] concluded, in a short passage, that the circumstances in that case fell within the aegis of advocate's immunity. The advice complained of was given at the point of an administrative function (the committal hearing) as part of the controversy which the trial ultimately determined. It was work which an advocate did out of court but was work which led to a decision which affected the conduct of the case at the subsequent trial.
54 In D'Orta-Ekenaike, the plurality judgment focused on the public interest in the finality of court-resolved controversies. Their Honours said at [45] that the central justification for the advocate's immunity is the principle that "controversies, once resolved, are not to be re-opened except in a few narrowly defined circumstances".
55 Consequently, there is analysis at [66]-[70] of the nature of the client's complaint, and the point is reached that - whether in a civil or criminal case - it is said at [80] that:
... no remedy is to be provided if its provision depends upon demonstrating that a different final (emphasis in original) result should have been reached in the earlier litigation.
56 The plurality in D'Orta-Ekenaike said at [34]:
A central and pervading tenet of the judicial system is that controversies, once resolved, are not to be reopened except in a few, narrowly defined, circumstances. That tenet finds reflection in the restriction upon the reopening of final orders after entry (63) and in the rules concerning the bringing of an action to set aside a final judgment on the ground that it was procured by fraud (64). The tenet also finds reflection in the doctrines of res judicata and issue estoppel. Those doctrines prevent a party to a proceeding raising, in a new proceeding, against a party to the original proceeding, a cause of action or issue that was finally decided in the original proceeding (65). It is a tenet that underpins the extension of principles of preclusion to some circumstances where the issues raised in the later proceeding could have been raised in an earlier proceeding (66).
57 Those rules based on the need for finality of judicial determination justify creating a range of immunities from suit, beyond the parties to the primary proceeding, including judges, witnesses and advocates: at [36]-[42]. The role of the judicial branch of government in "the quelling of controversies" precludes the re-litigation of that controversy, because its re-litigation would be:
... an inevitable and essential step in demonstrating that an advocate's negligence in the conduct of litigation had caused damage to the client" [at 44].
58 The next section of the reasons of the plurality examines (and rejects) the reasons why advocate's immunity as found in Giannarelli should be found no longer to exist, and explains why, on the particular facts in both Giannarelli and in D'Orta-Ekenaike, the advocate's immunity meant that the claim against the advocate could not be maintained because, to do so, it would have been necessary to demonstrate that the judicially quelled controversy should have been resolved differently.
59 Then, at [85] and [86], in the passage quoted in [30] above, the plurality said firstly that no sufficient reason had been shown to review the conclusion in Giannarelli, and secondly that it would not re-draw the line (as expressed by Mason CJ in Giannarelli) between the advocate's conduct or omissions which have the aegis of the immunity and those which do not.
60 The consequence is that, whilst the primary public policy considerations supporting the immunity have been refined and further explained, the plurality reasons in D'Orta-Ekenaike evince a clear intention to continue to recognise the immunity as recognised in Giannarelli and to maintain the line between where immunity comes into existence and where it does not exist as explained in Giannarelli. The reasons of the majority in Giannarelli, in particular of Mason CJ referred to above, indicate that the line is to be drawn where the work is advocate's work (whether provided by a barrister or a solicitor) and is in relation to work done in court or work done out of court which leads to a decision affecting the conduct of the case in court.
61 In that regard, the observations of McHugh J in D'Orta-Ekenaike in agreeing with the plurality are also apposite. His Honour said at [166] and [168]:
So, it is possible to sue a practitioner for the negligent settlement of proceedings or for the negligent loss or abandonment of a cause of action. Such claims lead to the litigation of a primary claim even if that claim can no longer be pursued. These results flow even though there is a public interest in the finality achieved through the statutes of limitations and the promotion of out-of-court dispute settlement. But where a trial has taken place, as the judgment of Gleeson CJ, Gummow, Hayne and Heydon JJ demonstrates, public confidence in the administration of justice is likely to be impaired by the re-litigation in a negligence action of issues already judicially determined.
...
Accordingly, the immunity should extend to any work, which, if the subject of a claim of negligence, would require the impugning of a final decision of a court or the re-litigation of matters already finally determined by a court.
62 This appeal concerns the drawing of the line. There is, as Giles JA said in Symonds v Vass (2009) 257 ALR 689 at 698, some difficulty in drawing that line where the relevant advocate's work or advice was done or given (or not done or given) prior to the commencement of the proceeding. There are similar observations by Giles JA and by Tobias JA in Attard v James Legal Pty Ltd [2010] NSWCA 311 at [31] and [188]-[190] respectively (Attard). In that case, one issue concerned whether an appellant could recover costs wasted by having to defend (successfully) a claim when there was a readily available defence not pleaded and which was likely to have led to the claim against that appellant not proceeding at a much earlier stage. There was no attempt to impugn the final decision, or to relitigate matters already decided, to use the phraseology of McHugh J in D'Orta-Ekenaike at [168].
63 Moreover, there appears to be a more robust application of the finality principle in some cases than in others. It is evident that the line is to be drawn at least where the proposed claim might cause an inquiry (and outcome) with a result which might differ from the judicially quelled controversy. In addition, a number of subsequent decisions support the conclusion that the line should be drawn in favour of immunity where the inquiry that would be prompted by the proposed claim might lead to a decision that the outcome of the judicially quelled controversy - even though it is accepted as being correct as it was presented - might be found to have produced a different result if the case had been conducted in a different way: see eg Donnellan v Woodland [2012] NSWCA 433 and Nikolaidis v Satouris [2014] NSWCA 448 (Nikolaidis), and the cases referred to by Barrett JA (with whom Beazley P and Ward JA agreed) at [28] and [43]: cf Nikolaidis and Alpine Holdings Pty Ltd v Feinaeur [2008] WASCA 85 (Alpine Holdings).
64 Alpine Holdings involved two claims against the legal adviser. The claim for damages for misleading and deceptive conduct against a landlord was successful at trial, but the amount of the damages awarded was substantially reduced on appeal. The claims against the legal adviser were first that, prior to the trial, the legal adviser had engaged in misleading and deceptive conduct about the amount of damages that Alpine Holdings would be entitled to, and secondly that, after the judgment and prior to the hearing of the appeal the legal adviser was negligent and engaged in misleading and deceptive conduct in the advice given in relation to an offer of settlement by the landlord. Those claims were struck out by a Master, on the basis that they were not arguable by reason of advocate's immunity.
65 The Court of Appeal regarded both claims as arguable. In relation to the second matter, it did not affect the conduct of the appeal. It was like advice on the prospects of success before action on which a decision is based whether or not to commence a claim. Nor did it involve any derogation from, or undermining of, the principle of the finality of Court decisions by requiring the re-opening of earlier litigation, as it was not alleged that the decision on the appeal reducing the damages was wrong or that the allegedly negligent conduct brought about a different result on that appeal. The claim did not require reconsideration of the correctness of that decision: see at [86]-[87].
66 In relation to the first matter, the Court of Appeal also considered that the claim did not plainly fall within the immunity. It was said that there will be cases where the manner of pleading would affect the way the case was conducted in Court, so that an allegation that the case should have been pleaded differently would involve re-opening the earlier decision in an endeavour to prove the result would have been different, but where the allegation is that the advocate advised the client to pursue a claim, and pleaded a cause of action when it was doomed to failure, it is not so obvious that it is necessary to re-open the original controversy: at [91]-[92].
67 In the light of those observations, we turn to the three issues on this ground of appeal.
