R (Nicklinson) v Ministry of Justice [2014] UKSC 38

Tony Nicklinson and Paul Lamb were almost completely paralysed, mentally competent and dependent on others for every aspect of physical care. Each wished to end his life but could not do so without another person performing the final act, which would amount to murder. Nicklinson sought a common-law defence of necessity for a doctor; after his death, his widow continued the litigation. Lamb challenged the murder prohibition under Article 8. A linked appellant, known as Martin, could take the final step himself with assistance and challenged the clarity of the Director of Public Prosecutions' policy under section 2 of the Suicide Act 1961. The cases raised intensely contested questions of autonomy, protection of vulnerable people and institutional competence.

Could the courts develop a necessity defence or declare the statutory prohibition on assisted suicide incompatible with Article 8, and was the prosecution policy sufficiently clear?

The Supreme Court dismissed all three appeals. It refused to develop a necessity defence permitting consensual killing, holding that such a major change involving safeguards and competing social interests was unsuitable for judicial creation. A majority accepted that the court had constitutional authority under the Human Rights Act 1998 to decide whether section 2 of the Suicide Act was incompatible with Article 8, even though Strasbourg allowed states a margin of appreciation. However, most Justices considered that Parliament should be given a further opportunity to address the issue before any declaration. Lady Hale and Lord Kerr would have issued one. Martin's challenge also failed because the DPP's policy, read as a whole, provided sufficient guidance and could not lawfully give advance immunity.

Courts have jurisdiction to consider a declaration that assisted-suicide legislation is incompatible with Article 8, but institutional competence and ongoing parliamentary consideration may justify restraint. Fundamental reform of murder and detailed safeguards is not appropriately achieved through a new necessity defence.

Nicklinson is a major authority on constitutional dialogue under the Human Rights Act. A declaration of incompatibility does not invalidate legislation, yet deciding whether to make one may require judicial assessment of sensitive policy and Parliament's proper role. The divided reasoning matters: the appeals failed, but the Court did not hold that assisted-suicide law was immune from rights review. R (Purdy) v DPP had already required clearer prosecutorial guidance, while later challenges have continued to confront evidential and institutional barriers. The legal position remains statutory unless Parliament changes it or a later court grants different relief.
