Derrick Wyatt

Emeritus Professor of Law


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 Fundación. 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, public international law, and constitutional law. 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. Cases involved the EU internal market, environmental issues and climate change, and international sanctions against the regimes in Iran and Syria.

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 Fundación, on the subjects of judicial reform, the role of judges, 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.

He publishes Derrick Wyatt's Law and Politics Blog on Substack and tweets on @BlogWyatt.  It contains original blogs along with re-posts of blogs of his already published by think-tanks etc. Recent original blogs cover climate change issues, the legality of transferring hospital patients to care homes during the pandemic, and a critical assessment of Tobias Ellwood MP’s recent proposal that the UK re-examine the option of striking a Norway-type deal with the EU to access the Single Market.

He has written for the LSE blog British Politics and Policy on obstacles to the UK rejoining the EU or renegotiating a soft Brexit via some sort of customs union with the EU and/or participation in the EU Single Market. He has also written for this blog on policy and legal issues around combatting climate change. He has written for the LSE blog European Politics and Policy on the subject of why the EU probably wouldn’t expel Hungary for its serial violations of the rule of law and human rights even if it could.

His most recent blog is on the subject of Scottish independence. He calls on UK politicians to ensure a more reliable mechanism for any further testing of Scottish opinion on independence, in the form of a double referendum, and to flag up the inescapable fact that the UK Government will only recognise an independent Scotland if the interests of the rest of the UK are respected. The blog has been published in the LSE's British Politics and Policy series, and provides the basis for an op-ed by the author in the Scotsman newspaper.
