On 30 March 1994, as Lord Chief Justice of Northern Ireland, he dismissed Private Lee Clegg's appeal against his controversial murder conviction. On 21 March 2002 Lord Hutton was one of four Law Lords to reject David Shayler's application to use a "public interest" defence as defined in section 1 of the Official Secrets Act 1989 at his trial. Lord Hutton represented the Ministry of Defence at the inquest into the killing of civil rights marchers on "Bloody Sunday". Later, he publicly reprimanded Major Hubert O'Neil, the coroner presiding over the inquest, when the coroner accused the British Army of murder, as this contradicted the findings of the Widgery Tribunal. Hutton also came to public attention in 1999 during the extradition proceedings of former Chilean dictator Gen. Augusto Pinochet. Pinochet had been arrested in London on torture allegations by request of a Spanish judge. Five Law Lords, the UK's highest court, decided by a 3-2 majority that Pinochet was to be extradited to Spain. The verdict was then overturned by a panel of seven Law Lords, including Lord Hutton on the grounds that Lord Hoffmann, one of the five Law Lords, had links to human rights groupAmnesty International which had campaigned for Pinochet's extradition. In 1978, he defended the UK at the European Court of Human Rights in the case of Ireland v United Kingdom, when the court decided that the interrogation techniques used were "inhuman and degrading" and breached the European Convention on Human Rights, but did not amount to "torture". The court also found that the practice of internment in Northern Ireland had not breached the Convention. He sentenced 10 men to 1,001 years in prison on the word of "supergrass" informer Robert Quigley, who was granted immunity in 1984. Lord Hutton was appointed by Tony Blair's government to chair the inquiry on the circumstances surrounding the death of scientist David Kelly. The inquiry commenced on 11 August 2003. Many observers were surprised when he delivered his report on 28 January 2004 and cleared the British Government in large part. His criticism of the BBC was regarded by some as unduly harsh; one critic commented that he had given the "benefit of judgement to virtually everyone in the government and no-one in the BBC.". In response to the verdict, the front page of The Independent newspaper consisted of one word, "Whitewash?" Peter Oborne wrote in The Spectator in January 2004: "Legal opinion in Northern Ireland, where Lord Hutton practised for most of his career, emphasises the caution of his judgments. He is said to have been habitually chary of making precedents. But few people seriously doubt Hutton's fairness or independence. Though a dour Presbyterian, there were spectacular acquittals of some very grisly IRA terrorist suspects when he was a judge in the Diplock era." Lord Hutton retired as a Law Lord on 11 January 2004. He remained a member of the House of Lords until retiring under the House of Lords Reform Act 2014 on 23 April 2018. He died on 14 July 2020 at the age of 88.
