During that time he was party to judgments in a broad spectrum of fields, including aviation, banking, competition and state aid, constitutional law and the Charter of Fundamental Rights, data protection and privacy, environmental protection, public international law, international trade and investment agreements, public procurement, sanctions, and tax. He has a particular expertise in investor-state dispute resolution as a judge who sat in Opinion 2/15 on the Free Trade Agreement between the EU and Singapore and in Opinion 1/17 on the Comprehensive Economic and Trade Agreement between the EU and Canada.
He was called to the Bar of England and Wales in 1979. He was appointed a KC in 1997. He practised at Monckton Chambers until 2012. He is a member of the Luxembourg Bar.
