Paul Key Q.C. is recognised as one of the leading QCs at the English Commercial Bar. He has particular expertise and specialism in arbitration, both international commercial arbitration and investment treaty arbitration (including ICSID). He also regularly appears in arbitration-related Court matters, including appearing in the English Supreme Court in Jivraj v Hashwani.
He has been ranked in the top-tier (band 1) rankings for arbitration for over 10 years and has consistently been identified as one of the leading figures in that field (“a real arbitration expert”, “few can rival his expertise, ability and knowledge in the field of arbitration”, “the first port of call for important arbitration disputes”, “an arbitration guru”).
He has appeared as advocate in over 300 major international arbitrations worldwide, as well as appearing regularly before the English Courts (at all levels) and foreign Courts on arbitration matters. In addition to his extensive experience in international commercial arbitration, he is one of the very few English QCs to have real expertise in investment arbitration. He has been lead counsel in a very large number of BIT / investment arbitrations, acting both for and against States.
