Lord Clarke has become the latest retired Supreme Court judge to go back into private practice, taking up a position at Arbitrators at 10 Fleet Street.

Arbitrators at 10 Fleet Street is a new and separate arbitrator wing set up by Quadrant Chambers. Full-time arbitrators include Sir David Steel, David Steward, Richard Lionberger and His Honour Harvey Crush.

Clarke LJ was one of the first Supreme Court justices. He began his career at the commercial Bar, before being appointed as a High Court judge in 1993, where he said in the Admiralty, Commercial and Crown court.

He was appointed to the Court of Appeal and Privy Council in 1998 and was Master of the Rolls from 2005 to 2009. He was the first High Court judge to be appointed directly to the Supreme Court. He was appointed to the Court of Final Appeal in Hong Kong in 2011 as a non-permanent judge.

Head of Quadrant Chambers Luke Parsons QC said: “We are delighted that The Rt Hon Lord Clarke has chosen to join Arbitrators at 10 Fleet Street. His outstanding experience, legal ability and unfailing charm will no doubt make him a much sought after arbitrator for international commercial disputes”.

The year 2017 has been a busy one for Clarke, who was one of judges presiding over the Article 50 challenge in the Supreme Court.

Clarke LJ also oversaw the landmark IP dispute between Eli Lilly and Actavis, in which the Supreme Court overturned a High Court and Court of Appeal decision in finding that pharmaceutical company Actavis had infringed the patent of its rival Eli Lilly in the UK, France, Italy and Spain.

Earlier this month, fellow Supreme Court judge Lord Nueberger joined One Essex Court, also to practice as an arbitrator with immediate effect.

Neuberger LJ retired from the highest juridical position at the end of September, following a career that saw him preside over the landmark Article 50 case, in which the court ruled that parliament could not rely on royal prerogative alone to trigger Article 50 and must seek parliamentary approval.

He became the country’s youngest Law Lord in 2007 after ­spending just two years in the Court of Appeal. His rise through the judicial ranks was one of the swiftest in legal ­history. In 2009, he became the 95th Master of the Rolls (MR) before he was made President of the Supreme Court in 2012.
