In April 2008, Beckett was appointed a floating sheriff, an office enabling him to sit where required throughout Scotland's six sheriffdoms, although he sat primarily in the Sheriffdom of Glasgow and Strathkelvin at Glasgow.[8]
Judge
In May 2016, Beckett was appointed as a Senator of the College of Justice.[9][10]
He was installed as a judge on 17 May 2016, taking the judicial title Lord Beckett.[1]
Lord Beckett was the judge responsible for the murder trial of Emma Caldwell, where he handed Iain Packer a 36 year sentence for her murder. This was the second longest in Scottish legal history.[11]
