In 1995, Hamilton was appointed a
Senator of the College of Justice with the judicial title,
Lord Hamilton. Although titled 'Lord', he is not a
peer; akin to the honorific title bestowed on the younger sons of
dukes and
marquesses who are also not peers. Between 1997 and 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, upon the latter's appointment to the
Appellate Committee of the House of Lords. Lord Hamilton took office on 2 December. As Lord President and Lord Justice General, he was responsible for the supervision of these Courts and for the determination of policy and rules of court procedure. He also made appointments to some tribunals and made recommendations to The Queen for the appointment of Queen's Counsel. He took full-time sick leave from April 2006, and was admitted to the
Priory Hospital in Glasgow. This prompted emergency legislation (the
Senior Judiciary (Vacancies and Incapacity) (Scotland) Act 2006) to be passed through the
Scottish Parliament in June. He returned to work without the need for the legislation to be invoked. In 2007, Lord Hamilton clashed publicly with the
Lord Advocate,
Elish Angiolini, over the collapse of the
World's End murders trial. The trial judge,
Lord Clarke, had ruled there was insufficient evidence for the jury to convict and threw the case out. The Lord Advocate, who is the senior
Law Officer in Scotland, had made a statement to the
Scottish Parliament, saying she was "disappointed" at this decision. However Lord Hamilton said her intervention had undermined the independence of the judiciary. ==Personal life==
