The third issue: Are the publications by the defendants giving rise to the imputations immune from suit?
34Mr Lawson explained his description of "working backwards" as arising from the particulars of publication provided by the plaintiff in the statement of claim. Although those affidavits have not been provided to me, it is clear from the statement of claim that the plaintiff's claim arises only from conversations between the first to fourth defendants and with the solicitor who acted for the first and second defendant and drafted the affidavits for all defendants.
35Immunity from suit for witnesses extends to all civil proceedings except malicious prosecution: Cumberland v Clark (1996) 39 NSWLR 514 at 520, citing R v Beydoun (1990) 22 NSWLR 256 at 259 - 260. The rationale is that there should be no collateral attack upon litigation. Although Mr Rollinson referred to Martin v Watson [1996] AC 74, the narrowly defined circumstances in which a claim for malicious prosecution may be brought against an individual as opposed to the prosecuting authority are not relevant here, and remain controversial in Australia.
36A party's private communications with his lawyer, or with other witnesses or potential witnesses in the proceedings, for the purpose of preparation of affidavits forms part of the protection afforded by the absolute privilege afforded to that affidavit (Brown on Defamation (2nd Ed., Carswell), [12.4.5(j)]). In Lincoln v Daniels [1962] 1 QB 237 at 260 Devlin LJ, referring to the absolute immunity afforded to pleadings, stated: "A plaintiff in a libel action could not be allowed to say, "I do not bring the action against you for what was said in the statement of claim but for what you instructed your solicitor and counsel to put into the statement of claim."
37Mr Rollinson's submission is that the House of Lords in Watson v M'Ewan, supra, held that this privilege did not extend to conversations between parties, their legal representatives and their witnesses for the purpose of preparing their affidavits or otherwise seeking instructions. The Lord Chancellor, with Lord James and Lord Robertson agreeing, noted the absolute immunity of the evidence contained in a witness statement or affidavit used in court as "too plain for argument", and went on to note that this extended to the conferences with the solicitor for the preparation of the evidence:
"But then comes the question which, so far as I know, has been raised for the first time in this case. The ingenious suggestion has been made that although it is true that a witness is protected from an action in respect of evidence actually given in a Court of justice, yet no such protection exists in respect of his attendance before the solicitor at what is called apparently in Scottish law his precognition - what we call the interview between the intended witness and the solicitor who takes from him what we call the proof - that is to say, reduces to writing the evidence which the witness is about to give. One very serious element of difficulty which those who insist upon such a liability have to meet is manifest - namely, that in the whole course of the diligent inquiry that the learned counsel on both sides have made into this matter they have not found that any such liability has ever been sought to be established before. So far as I know personally in my experience no such question has ever arisen. The learned Judges who have allowed these issues have done so apparently for the first time in this case.
It appears to me that the privilege which surrounds the evidence actually given in a Court of justice necessarily involves the same privilege in the case of making a statement to a solicitor and other persons who are engaged in the conduct of proceedings in Courts of justice when what is intended to be stated in a Court of justice is narrated to them - that is, to the solicitor or Writer to the Signet. If it were otherwise, I think what one of the learned counsel has with great cogency pointed out would apply - that from time to time in these various efforts which have been made to make actual witnesses responsible in the shape of an action against them for the evidence they have given, the difficulty in the way of those who were bringing the action would have been removed at once by saying, "I do not bring the action against you for what you said in the witness-box, but I bring the action against you for what you told the solicitor you were about to say in the witness-box." If that could be done the object for which the privilege exists is gone, because then no witness could be called; no one would know whether what he was going to say was relevant to the question in debate between the parties. A witness would only have to say, "I shall not tell you anything; I may have an action brought against me to-morrow if I do; therefore I shall not give you any information at all." It is very obvious that the public policy which renders the protection of witnesses necessary for the administration of justice must as a necessary consequence involve that which is a step towards and is part of the administration of justice, namely, the preliminary examination of witnesses to find out what they can prove. It may be that to some extent it seems to impose a hardship, but after all the hardship is not to be compared with that which would arise if it were impossible to administer justice, because people would be afraid to give their testimony.
38The House of Lords then appeared to leave open whether the privilege extends to the witness whose affidavit is not tendered, and does not take an oath in court to be cross-examined on his affidavit:
The hardship to which I refer is this: That although when a witness does give evidence which is wilfully false you can indict him for perjury; on the other hand, if he makes the same statement, not upon oath, to a person taking down the evidence he is prepared to give, it seems to be very difficult to devise anything that would bring him to justice for that false statement. The answer, of course, dealing with it as a matter of convenience and indeed of necessity for the administration of justice, I suppose, is this: Unless he does give evidence in a Court of justice, in which case he can be indicted for perjury if his evidence is wilfully false, nobody knows anything about it - it slumbers, I suppose, in the office of the solicitor, and nobody hears or cares anything about it. Practically, I think that would be the answer. But whether that be a good answer or not, what seems to me to be an overwhelming consideration in the determination of this case is that a witness must be protected for his preliminary statement or he has no protection at all, and that there is that protection established is, as I have already said, beyond all possibility of doubt."
39While the House of Lords was uncertain about the extent of this immunity in 1905, it is now settled law that immunity from suit extends to persons interviewed as witnesses even if the testimony is never given, or not presented in court. In Lincoln v Daniels, supra, at 258, Devlin LJ, noting the reference in Watson v M'Ewen to this category of absolute privilege as "the most difficult" to define, went on to say it was "immaterial whether the proof is or is not taken in the course of proceedings"; see also Page v McGovern [2008] TasSC 13 at [30]; Paterson v Hesse [1914] 34 NZLR 177 at 181 per Hosking J; McCabe v Joynt [1901] 2 Ir R 115 at 127 (QBD). This has even been held to extend to the usual solicitors' inter partes correspondence, and as not being confined to documents required for use in court: Wong Shui Kee v Chu [2003] 1 HKC 125 (considered in Cunliffe v Woods [2012] VSC 254). The fact that there are others present when the testimony is discussed will not defeat that privilege if those persons are not otherwise strangers to the action: Thompson v Turbott [1963] NZLR 71, such as another witness: Ascherman v Natanson 23 Cal App 3d 861, 100 Cal Rptr 656 (1972).
40A potential additional requirement in More v Weaver [1928] 2 KB 520 (a decision which, while doubted, has never been overruled: see Clark v Davey [2002] EWHC 2342), namely that the remarks would need to be relevant to the pleadings or subject matter of the proceedings, is not an issue here, as the imputations pleaded by the plaintiff are a agreed to be a compilation of the allegations made in the affidavits sworn by each of the defendants.
41As Mr Lawson noted, a further problem is that the conversations the defendants had with their solicitor and with each other in relation to the preparation of these proceedings would be protected by legal professional privilege: Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission (2002) 213 CLR 543 at [11]; Re Neenan [2011] AATA 372. Conversations between a solicitor and client are themselves the subject of absolute privilege at common law: Brown on Defamation (2nd Ed., Carswell), at [12.4(4)(c) ff]. This is the corollary of the submission that the defendants' statements to their legal representatives and each other for the purpose of preparing the probate proceedings were made on a protected occasion. Even if they were not, they were made on an occasion of solicitor/client or common interest privilege and as such the plaintiff cannot compel their production. That includes conversations and communications between the cross-claimants (the first and second defendants) in the Supreme Court proceedings with each other and their witnesses, which would be protected by the common interest legal professional privilege explained by Giles JA, as well as by the immunity from suit to which witnesses are entitled.
42Further, as Mr Lawson noted in his submissions, any publications made prior to 16 April 2013 fall outside the one year limitation period for defamation proceedings. This is of particular significance to the publications asserted to have been made by the first and second defendants, which more than likely were made prior to that date.
43Finally, the defendants submit that the claim is an abuse of process. This argument was not developed by the defendants, or responded to by the plaintiff, but I note that the issues raised here reflect some of the court's concerns in Moevao v Department of Labour [1980] 1 NZLR 4 and Higgins J in Emanuele v Headley (Supreme Court of the ACT, Higgins J, 7 March 1997). (See also Calabro v Zappia [2010] NSWDC 127, where the matter complained of was a potential witness's statutory declaration, surreptitously removed by one of the plaintiffs from a bundle of papers in the courtroom foyer.)
44Accordingly, the proceedings against the first to fourth defendants should also be dismissed on the basis that the publications identified in the statement of claim are protected by absolute privilege under s 27(2) of the Act.
