Montgomery v Lanarkshire Health Board was a landmark decision of the House of Lords in 2015 that redefined the standard for informed consent in medical negligence within the United Kingdom. The ruling overruled aspects of precedent set by Bolam v Friern Hospital Management Committee and emphasized patient autonomy drawing on developments in medical ethics, human rights law, and comparative jurisprudence from jurisdictions such as Canada and Australia. The judgment has had broad implications for clinical practice in institutions including the National Health Service and for litigation in courts such as the Supreme Court of the United Kingdom and the Court of Appeal of England and Wales.

Background

The case arose against the backdrop of evolving standards for disclosure in medical practice, tracing influences from precedents like Bolam v Friern Hospital Management Committee and doctrinal developments in cases including R (on the application of Burke) v General Medical Council and international authorities such as Canterbury v Spence (United States), Rogers v Whitaker (Australia) and decisions of the European Court of Human Rights. Debates about informed consent had engaged institutions such as the General Medical Council, the British Medical Association, and scholarship linked to universities including Oxford University, Cambridge University, Edinburgh University and King's College London. The legal context included statutory regimes like the Human Rights Act 1998 and professional guidance from bodies such as the Medical Defence Union.

Facts and lower court proceedings

The appellant was a mother who gave birth in a hospital run by the defendant health board in Scotland. The claimant, represented by solicitors and advocates with links to chambers in London and Edinburgh, contended that obstetric advice from an obstetrician and consultant failed to disclose a risk of shoulder dystocia associated with vaginal delivery of a baby of expected large birthweight, leading to the child sustaining permanent disabilities. Proceedings commenced in the Scottish courts, moving through the Court of Session where judges considered expert evidence from consultants in obstetrics, gynaecology, and neonatology as well as submissions invoking professional standards from the Royal College of Obstetricians and Gynaecologists and guidance from the National Institute for Health and Care Excellence. The lower courts applied the Bolam test, concluding that the conduct did not amount to negligence; the case was then appealed to the House of Lords.

House of Lords decision

In a leading judgment delivered by Law Lords including Lord Kerr, Lord Reed, and Baroness Hale of Richmond, the House of Lords allowed the appeal. The appellate court held that the test for disclosure of risks is not governed solely by medical opinion as in Bolam but must account for what a reasonable person in the patient's position would want to know, and what risks a reasonable clinician should disclose. The Lords drew upon authorities such as Bolam v Friern Hospital Management Committee, Rogers v Whitaker, Canterbury v Spence, and domestic instruments including the Human Rights Act 1998 and decisions from the European Court of Human Rights to frame a patient-centred standard. The judgment endorsed an approach that privileges autonomy and informed decision-making and set out criteria for materiality of risk, foreseeability, and the clinician’s duty to warn.

Legal principles and significance

The decision articulated several core principles: replacement of a wholly professional-deference test for disclosure with a standard focused on materiality to the particular patient; recognition of patient autonomy rooted in values expressed in instruments like the European Convention on Human Rights; and guidance on the assessment of causation and remoteness in negligent non-disclosure. The ruling affected professional obligations under guidance from the General Medical Council and reshaped negligence analysis in courts including the Court of Appeal of England and Wales, the High Court of Justice, and appellate tribunals across Scotland and Northern Ireland. The case influenced policy at the Department of Health and Social Care and training curricula at medical schools such as University College London and Imperial College London.

Subsequent developments and impact

Post-decision, judicial interpretation in cases before the Supreme Court of the United Kingdom and appellate courts refined application of the test to areas such as elective surgery, obstetrics, and anaesthesia, and intersected with statutory frameworks like the Access to Health Records Act. Professional regulators updated guidance to reflect the requirement to engage with patients about risks relevant to individual circumstances. Comparative jurisdictions, including courts in Canada, Australia, and New Zealand, cited the decision in their own jurisprudence on consent and negligence. The decision also spurred reforms in hospital consent forms, risk communication protocols in trusts such as NHS England, and academic commentary across law faculties at University of Edinburgh and University of Glasgow.

Commentary and criticism

Scholars, clinicians, and professional bodies offered mixed reactions: proponents praised the enhancement of autonomy and alignment with contemporary ethical standards championed by commentators from Harvard Law School and Yale Law School, while critics warned of potential defensive medicine, increased litigation, and burdens on clinical time as noted in analyses from The BMJ and The Lancet. Debates engaged legal academics from Oxford University Press and practitioners in chambers at Middle Temple and Gray's Inn, focusing on practical challenges in determining what the "reasonable patient" would want to know and the evidential burdens in causation. Subsequent literature considered the ruling alongside landmark statutes and cases such as Montgomery-related guidance in professional codes and comparative case law.
