Arthur Campbell Hamilton, Lord Hamilton, PC (born Glasgow, 10 June 1942), is Scotland's most senior judge. He was chosen as Lord Justice General and Lord President of the Court of Session in November 2005, succeeding Lord Cullen.
Arthur Campbell Hamilton was born in Glasgow and attended Glasgow High School. He studied at the University of Glasgow, Worcester College, Oxford University and Edinburgh University, where he gained an LLB in 1967.
He was admitted to the Faculty of Advocates in 1968 and became a QC in 1982. He was an Advocate Depute (1982–1985), Chairman of the Medical Appeals Tribunals (1988–1992) and President of the Pensions Appeal Tribunal (Scotland) (1992–1995). Over several months in 1992–1993, during the indisposition of the Sheriff Principal of Tayside, Central and Fife, he acted as a temporary Sheriff Principal in that sheriffdom. From 1988 to 1995 he was a Judge of Appeal of the Courts of Appeal of Jersey and Guernsey.
In 1995 he was appointed as a Senator of the College of Justice. Between 1997-2000 he was a full-time commercial judge dedicated to commercial business and responsible for oversight of that aspect of Court of Session business. In January 2002 he was appointed as a Judge of the Inner House of the Court of Session where he sat principally on appellate business.
On 24 November 2005, the Scottish Executive announced that he would succeed Lord Cullen as Lord Justice General and Lord President of the Court of Session. He took up office on 2 December. He took full-time sick leave from April 2006, prompting emergency legislation (the Senior Judiciary (Vacancies and Incapacity) (Scotland) Act 2006) to be passed through the Scottish Parliament in June. He has since returned to work, without the need for the legislation to be invoked.
