Derrick Wyatt has been a Fellow of St. Edmund Hall and a CUF lecturer since 1978, received the title of Professor in 1996, and retired in 2009.
His teaching included EU law, constitutional and administrative law, and public international law. He was Visiting Professor of Law at Oxford 2009 - 2014, teaching the law of the EU’s internal market.
He has published numerous articles and contributions to books, served on editorial committees and boards and he co-authored Wyatt and Dashwood's European Union Law, in its various editions, the latest being its 6th edition (Hart Publishing 2011). He is a member of the International Academic Council of the Fide Fundacion. Fide is the leading legal-economic think-tank in Spain, committed to involving civil society in the discussion of major legal-economic-scientific developments; it is independent and non-partisan.
He practised (Queen's Counsel 1993) from Brick Court Chambers until 2018, specialising in litigation before the European Court of Justice and the EU General Court in Luxembourg, and in giving legal advice to businesses and governments. This involved aspects of EU law, issues of public international law, constitutional law in the UK and Cyprus, and, latterly, Brexit issues. He appeared in numerous cases before the European Courts in Luxembourg and represented and/or advised businesses in the UK, Ireland, the USA and Germany, and the Governments of the UK, Northern Ireland, and Cyprus.
Since the Brexit referendum, he has briefed the media, lawyers and financial service providers on Brexit and negotiations between the UK and the EU. He has appeared before UK Parliamentary Committees giving evidence on Brexit related issues, including the consequences of a "no-deal", and parliamentary scrutiny of the negotiation of trade agreements.
He has written for the think-tanks Policy Exchange, UK in a Changing Europe, and the Fide Fundacion, on the subjects of judicial reform, the provisional application of EU trade agreements, the threat by the UK Government to break its commitments to the EU on Northern Ireland, the Trade and Cooperation Agreement between the EU and the UK, and the feasibility of an independent Scotland joining a customs union with a "New UK". He has written and presented podcasts for Fide on the economic and political implications of the Trade and Cooperation Agreement. His latest blogs for Fide and UK in a Changing Europe argue that supreme courts should join in public debate to increase their legitimacy in the democratic societies in which they operate, and that transparency is a better form of accountability than excessive involvement of politicians in the selection of judges.
