Factual and Procedural Background
This appeal concerns evidence given by an expert witness, Professor Meadow, in the prosecution of the Appellant for the murder of her two infant sons. The Crown relied partly on Professor Meadow's evidence to challenge the possibility that the deaths were due to Sudden Infant Death Syndrome (SIDS). The Appellant was convicted, and her first appeal was dismissed. However, her second appeal succeeded on the basis of non-disclosure by the Crown's pathologist, leading to quashed convictions without a retrial.
Following this, a complaint was made to the General Medical Council (GMC) alleging serious professional misconduct by Professor Meadow regarding his expert evidence. The GMC's Fitness to Practise Panel (FPP) found him guilty and ordered erasure from the medical register. Professor Meadow appealed, and the High Court quashed the GMC order, holding that he was immune from disciplinary proceedings arising from his evidence. The GMC was granted permission to appeal this decision.
The appeal involves two main issues: (1) whether expert witnesses should have immunity from disciplinary or fitness to practise (FTP) proceedings in respect of evidence given in legal proceedings; and (2) whether Professor Meadow was guilty of serious professional misconduct. The Attorney General intervened in the first issue supporting the GMC.
Legal Issues Presented
- Whether an expert witness is entitled to immunity from disciplinary, regulatory, or fitness to practise proceedings in respect of statements made or evidence given in or for legal proceedings.
- Whether the GMC's Fitness to Practise Panel was correct in finding Professor Meadow guilty of serious professional misconduct based on his expert evidence.
Arguments of the Parties
GMC's Arguments
- Expert witnesses should not enjoy immunity from FTP proceedings because the purpose of such proceedings is to protect the public by ensuring fitness to practise.
- The immunity from civil suit does not and should not extend to FTP proceedings, which have a distinct public interest.
- The GMC has a statutory duty to investigate and discipline practitioners whose fitness to practise is impaired, including conduct arising from expert evidence.
- Extension of immunity would improperly limit the jurisdiction and statutory duties of FTP bodies.
- The judge’s suggestion that immunity should depend on referral by the trial judge is inappropriate and inconsistent with statutory schemes.
- Professor Meadow's conduct in giving expert evidence was outside his expertise, misleading, and amounted to serious professional misconduct.
Professor Meadow's Arguments (via Counsel)
- He should have immunity from FTP proceedings arising from evidence given in court, based on public policy considerations to protect expert witnesses from deterrence.
- The immunity from civil suit should be extended, with some qualifications, to disciplinary proceedings.
- His statistical evidence, while mistaken, was given honestly and without intention to mislead.
- The errors were common, widely made, and did not justify a finding of serious professional misconduct.
- The FPP applied an overly harsh standard, partly due to Professor Meadow’s eminence.
- The trial judge and parties did not challenge the admissibility of the statistical evidence.
Attorney General's Position
- Supports the GMC’s appeal that expert witnesses do not have immunity from FTP proceedings.
- Any extension of immunity to FTP proceedings should be a matter for Parliament, not the courts.
- FTP proceedings serve an important public interest distinct from civil suits.
- Concerns about deterring expert witnesses should be addressed by rule changes or legislative action, not by extending immunity.
Judge's Position (High Court - Collins J)
- Held that expert witnesses have immunity from FTP proceedings based on public policy to avoid deterring witnesses.
- Suggested a conditional immunity dependent on referral by a trial judge, which was a novel approach not supported by parties.
- Found that Professor Meadow’s errors did not amount to serious professional misconduct.

Court's Reasoning and Analysis
The court analysed the common law immunity of witnesses, including expert witnesses, which protects them from civil suits arising from evidence given in judicial proceedings. It acknowledged the immunity’s rationale: encouraging witnesses to testify freely and avoiding multiple litigations challenging the same evidence. However, the court emphasised that this immunity traditionally does not extend to criminal prosecutions for perjury or to disciplinary proceedings.
The court rejected the extension of immunity to FTP proceedings on the ground that the purpose of such proceedings is distinct and paramount: the protection of the public by ensuring practitioners remain fit to practise. Extending immunity would conflict with statutory duties of regulatory bodies and could allow unfit practitioners to continue practising unchecked.
The judge’s novel proposal of conditional immunity dependent on trial judge referral was criticised as arbitrary, impractical, and inconsistent with the need for certainty in immunity. The court held that such a significant policy change should be made by Parliament or the relevant regulatory authorities, not by judicial extension of common law immunity.
Regarding the allegations of serious professional misconduct, the court reviewed the evidence focusing on Professor Meadow’s use of statistical evidence at trial. It found that he misunderstood and misapplied statistical principles outside his expertise, failed to disclose this lack of expertise, and presented evidence that risked misleading the jury.
However, the court accepted that Professor Meadow acted honestly and without intention to mislead, and that the errors were common and widely made. It noted that the statistical evidence was a side issue at trial, and the main prosecution case was supported by other evidence. The court found that while Professor Meadow’s conduct fell below professional standards, it did not amount to serious professional misconduct justifying erasure from the medical register.
The court also emphasised the importance of assessing expert conduct within the forensic context, including the adversarial nature of trials, the roles of counsel and judges in managing evidence, and the isolation of expert witnesses in the witness box.
Holding and Implications
The court reached the following conclusions:
1. Immunity from Fitness to Practise Proceedings: Expert witnesses do not have immunity from disciplinary or fitness to practise proceedings arising from evidence given in court. The existing common law immunity from civil suit does not extend to such regulatory proceedings. The court held that extending immunity would conflict with statutory duties to protect the public and is a matter for Parliament or regulatory bodies, not the courts.
2. Serious Professional Misconduct: The court overturned the finding of serious professional misconduct against Professor Meadow. It held that although he made significant errors in his use of statistics and failed to disclose his lack of expertise, these mistakes were honest and did not justify the severe sanction imposed. The GMC’s appeal against this finding was dismissed.
Implications of this decision include:
- The decision clarifies that expert witnesses remain subject to professional regulation and disciplinary action for misconduct in evidence given in legal proceedings.
- The court emphasises the need for clear statutory or regulatory frameworks to address concerns about deterring expert witnesses, rather than judicially-created immunities.
- The ruling underscores the importance of expert witnesses adhering strictly to their expertise and disclosing limitations to avoid misleading courts.
- No new precedent was set extending immunity; rather, the judgment reinforces existing legal principles and statutory duties.
