But it does not matter whether the action is framed as an action for defamation or as an action analogous to an action for malicious prosecution or for deceit or, as in this instance, for combining or conspiring together for the purpose of injuring another; the rule of law is that no action lies against witnesses in respect of evidence prepared ( Watson v McEwan [1905] AC 480 at 486), given, adduced or procured by them in the course of legal proceedings. The law protects witnesses and others, not for their benefit, but for a higher interest, namely, the advancement of public justice ( Seaman v Netherlift (1876) 2CPD 53 at 62; Goffin v Donnelly (1981) 6 QBD 307 at 308) . The remedy against a witness who has given or procured false evidence is by means of the criminal law or by the punitive process of Contempt of Court: see Watson v McEwan ."
18 The rule expressed above has been referred to in English decisions as "the core immunity". But how far does the witness immunity rule extend? When this immunity has been challenged, the courts have examined the connection (or proximity) between witness and the court proceedings. In England the immunity does not extend to cover police officers that have deliberately fabricated evidence.
19 In the English case Evans v London Hospital Medical College [1981] 1 WLR 184, the facts are somewhat similar to these current proceedings. In Evans the first defendants provided post mortem investigations and reports and toxicological investigations at the request of the police and the DPP, after the plaintiff's 5-month-old son died. The defendants carried out the analysis where concentrations of morphine were found in various organs. These test results were communicated to the police who then charged the plaintiff with murder. At trial, the prosecution offered no evidence so she was acquitted. The plaintiff claimed damages as a result of her arrest, detention and having to undergo a trial. The particulars of negligence included that the defendants had been negligent in allowing the organs to be removed at the post mortem to become contaminated with morphine. The defendants successfully sought summary dismissal of the proceedings on the basis that they were immune from civil proceedings.
20 In Evans, Drake J discussed witness immunity and his approach is discussed and refined in subsequent cases. According to Drake J, if the administration of justice was impeded because witnesses would be in fear that persons against them might subsequently involve them in costly litigation, then if this occurred, it is essential that the immunity given to a witness should also extend to cover statements he makes prior to the issue of a writ or commencement of a prosecution, provided that the statement was made for the purpose of a possible action or prosecution and at a time when a possible action or prosecution is being considered.
21 If immunity does not extend to such statements it would mean that the immunity attaching to the giving of evidence in court or the formal statements made in preparation for the court hearing could easily be out-flanked and rendered of little use. Immunity must extend also to the acts of the witness in collecting or considering material on which they may later be called to give evidence. If it does not so extend then a convicted person could, for example, sue the police officers for the allegedly negligent manner in which they had investigated the crime, by complaining that they had wrongly assessed the evidential value of certain matters or had failed to interview possible witnesses whose evidence was thought by the accused to be favourable to him.
22 Since then, in England the House of Lords have refined Drake J's view as expressed in Evans. While the House of Lords in Darker v Chief Constable of West Midlands [2001] 1 AC 435 reaffirmed that witnesses in a civil or criminal trial have complete immunity from suit if the plaintiff's claim relates to things said or done in the witness box, but held that such immunity did not apply where police officers were found to have deliberately fabricated evidence. This is because what was under attack in the case was not the investigation of "possible realities but the preparation of a fiction." - (per Lord Clyde at 461).
23 The issue is whether in the case before me, it is arguable that immunity should not be extended to Ballard in circumstances where he "interacted" with the CMA testing and put forward a misleading and inaccurate summary of tests done. The shortcomings in carrying out the testing of the drug caused serious doubt upon the integrity of his opinion. If the English law were applicable I would allow this matter to go to trial as it is arguable that Mr Ballard's evidence borders on being classified as fabricated.
24 Reverting to Australia law, in Mann v O'Neill (1997) 71 ALJR 903; (1997) 191 CLR 204, the High Court (per Brennan CJ, Dawson, Toohey and Gaudron JJ) referred to it being well settled that absolute privilege attaches to all statements made in the course of judicial proceedings, whether made by parties, witnesses, legal representatives, members of the jury or by the judge. It also extends to oral statements and to statements in the originating process, in pleadings or in other documents produced in evidence or filed in the proceedings. However, in Mann McHugh J, at 221, warned against "the temptation to recognise the availability of the defence for new factual circumstances simply because they are closely analogous to an existing category (or cases within an existing category) without examining the case for recognition in light of the underlying rationale for the defence." In Jovanovic & Anor v Woods & Ors [2001] TASSC 96 (15 August 2001) and Sovereign the court considered whether the immunity extended to the preparation of expert reports and held that it did so extend. In Australia, the law has not as yet excluded fabricated evidence from being covered by witness immunity.
25 Nevertheless, taking the McHugh approach in Mann, I should examine the factual circumstances in these proceedings in light of the underlying rationale for the witness immunity principle. The public policy reasons for the immunity are firstly, so as to encourage honest and well meaning persons to assist the higher interest of the advancement of public justice even if a dishonest and malicious person may on occasions benefit from the immunity; secondly, the rule is designed to encourage freedom of speech and communication in judicial proceedings by protecting persons who take part from fear of being sued for something they say in the judicial process from the preparation of reports to the giving of evidence; and thirdly, to ensure that there is finality to litigation, so there is no opportunity for relitigating the same issues by means of subsequent actions.
26 This is one case where if the public policy objective is to be achieved then Mr Ballard gains the advantage of being given immunity even though his integrity was in doubt. The second and third objections are achieved if the witness immunity rule is applied. I accept that the common law develops incrementally but I do not think that it is arguable Mr Ballard's evidence and the issue of the certificate falls outside the principle of witness immunity.
27 The allegations of misfeasance in public office as against the first defendant are firstly, that the first defendant signed the certificate in the purported exercise of powers under ss 37A and 37B of the Poisons and Therapeutic Goods Act 1966 (NSW) and the Drugs and Misuse and Trafficking Act 1985 (NSW) which were limited to certifying "the result of analysis of substances provided to him for analysis"; secondly, intending that it would be provided to and relied on by the DPP; thirdly, knowing that it would prejudice the plaintiff's interests; fourthly, "recklessly not caring" whether it was correct; and fifthly, accordingly, "recklessly indifferent as to whether it was a certificate he was empowered to give". The malicious prosecution, the TPA and negligence claims are covered by the witness immunity principles - see Sovereign paras 41-45.
28 The law in Australia in respect of witness immunity is well settled. It is my view that the plaintiff's claims in the PFASC as against the first and second defendants are futile. The FASC should be dismissed against them. The FASC discloses no reasonable cause of action against them and should be dismissed.
29 Costs are discretionary. Costs usually follow the event. The plaintiff is to pay the first and second defendants' costs as agreed or assessed.
