He was educated at George Watson"s College, and took an Master of Arts at the University of Aberdeen.
His family moved to Edinburgh when he was two years old, where he was brought up. He worked as an English teacher at the Vale of Leven Academy in Dumbartonshire during 1973-1975, before returning to university to study law at the University of Strathclyde. Campbell was admitted as a solicitor in 1979 and entered the Crown Office and Procurator Fiscal Service as a prosecutor.
He was admitted to the Faculty of Advocates in 1985, called to the English Bar at the Inner Temple in 1990, and served as an Advocate Depute from 1990 until 1993.
In 1995, he became a Queen"s Counsel and Standing Junior Counsel to Her Majesty Customs and Excise. In 1997 he was appointed Home Advocate Depute (Scotland"s senior prosecutor) and remained in this post until 2001.
Campbell was senior counsel for the Crown (prosecutor) in the trial over the Lockerbie bombing at the Scottish Court in the Netherlands, under former Lord Advocate Lord Boyd of Duncansby, and alongside Alan Turnbull, also now a judge. Libyan intelligence officer Abdelbaset al-Megrahi was found guilty of the 270 murders, and was sentenced to life imprisonment in 2001.
The conviction, though controversial, was upheld on appeal and the successful prosecution brought Campbell international prominence.
In 2003, Campbell was appointed a Senator of the College of Justice, a Judge of the Court of Session and High Court of Justiciary, taking the judicial title "Lord Bracadale". Bracadale is a village on the Isle of Skye. Lord Bracadale has presided over some of the most high-profile and controversial criminal trials in recent Scottish history.
In 2010, he was the judge in Her Majesty Advocate v Sheridan and Sheridan.
In 2012, he twice presided over murder trials which resulted in convictions despite the absence of a body. In the first of these, Health Management Associates v Gilroy, television cameras were allowed into the High Court in Edinburgh to record the sentencing of the convicted, David Gilroy.
This marked the first time in the United Kingdom that a murder sentence was filmed for same day broadcast. This too was filmed, and the resultant two-hour documentary The Murder Trial (shown on Channel 4 on 9 July 2013) included interviews with participants, including Lord Bracadale.
Bracadale took up an appointment to the Inner House on 1 March 2013.
He has consequently been appointed, by Her Majesty the Queen, to the Privy Council.
