Pre-eminent public international law set, remaining at the forefront of the most cutting-edge international disputes. The set's academically accomplished barristers field significant expertise in state-versus-state disputes and BIT arbitration. They frequently appear before the ICJ and all of the other major international courts and tribunals, as well as the UK and European courts. Members are highly adept at handling the full spectrum of PIL issues, often advising governments, international organisations and corporations on land and sea territorial disputes, international trade and investments, and state immunity. They are also able to advise on related human rights and international criminal law issues. Recent highlights have included Ukraine v Russia, concerning the latter's alleged interference with maritime rights in the Black Sea, and a dispute between Guyana and Venezuela arising out of long-running tensions over the contested Essequibo region.
