Lord Mance has been appointed deputy president of the Supreme Court in succession to Baroness Hale, who steps up to the top job next week.
However, he will hold the post for less than a year, as he will have to retire next June when he reaches the age of 75.
He enjoys the later retirement age – it is now 70 – as he has been in the highest court since 2005, when it was still the House of Lords.
Lord Mance joined the High Court in 1993 and the Court of Appeal in 1999, where he sat with his wife Lady Justice Arden – the first time a wife and husband had been on the appeal bench at the same time.
He read law at University College, Oxford, spent time with a Hamburg law firm and then practised at the commercial bar and sat as a recorder until 1993.
He chaired various banking appeals tribunals and was a founder director of the Bar Mutual Indemnity Insurance Fund. He represented the UK on the Council of Europe’s consultative council of European judges from 2000 to 2011, being elected its first chair from 2000 to 2003.
Lord Mance was in the spotlight in the run-up to the Supreme Court hearing the article 50 case as he had to cancel a speech about the law and Europe given the political sensitivities.
He said: “I look forward to playing my part in the leadership of the court and in furthering the collaborative relationships which exist with the president, with the chief executive and within the court generally, as well as to promoting the Court’s role and activities both as an established institution in our national life and internationally.”
Lady Hale said: “He has already made a huge contribution; as a presider and as the lead Justice for our international relations with other courts and judicial networks. I am sure that together we shall make a great team.”
