Over the last decade, he has been named each year in the Top 20 “Global Elite Thought Leaders” by Who’s Who Legal, which describes him as “the leading arbitration lawyer in London”, “exquisite as an advocate”, and “a leader of his generation”. Chambers recognises him as one of only two “Star Individuals” in international arbitration in London, with a market source saying he is “seen as one of the go-to people in the world for a party who is involved in a large and complex arbitration”. He is also listed in the “Hall of Fame” for international arbitration in The Legal 500.

Constantine is a co-author of the fourth, fifth, and sixth editions of the leading textbook on international arbitration, Redfern and Hunter on International Arbitration. He is a Member of the ICCA Governing Board and a Director of the LCIA Board.
