Guglielmo Verdirame QC, has been in practice at the English Bar since 2006. His practice covers public international law and international arbitration (especially investment treaty arbitration and inter-state arbitration).
He is recognised as one of the leading practitioners in these fields by the main legal directories. He is regularly instructed as counsel in cases before English courts; international courts (including the International Court of Justice and the International Tribunal for the Law for the Law of the Sea); and arbitral tribunals (ICSID, ICSID-Additional Facility, PCA, UNCITRAL, ICC, SCC, LCIA, Court of Arbitration for Sport). While he mainly works as counsel, he has also occasionally sat as arbitrator.
He was appointed Queen’s Counsel (QC) in 2019. Until taking silk, Guglielmo sat as a member of the UK Attorney General’s A Panel of Counsel in Public International Law. He has appeared for the UK Government before the International Court of Justice (ICJ), UK Supreme Court and Court of Appeal in some of the leading PIL disputes.
For many years, Guglielmo combined his professional career at the Bar with academia. He is still Professor of International Law at King’s College London, albeit only on a part-time basis. In past, he was a Fellow of the Lauterpacht Centre for International Law at the University of Cambridge (2003-2011), and a Fellow of Merton College, Oxford (2000-2003). He was a Visiting Professorial Fellow at Harvard Law School (2006) and a Visiting Professor at Columbia Law School (2015). He has published extensively in the field of public international law, and currently sits on the Advisory Board of the American Review of International Arbitration.
