His experience working across a variety of legal cultures helps him bring a practical, down-to-earth, and team-oriented approach to his cases. Given his background and experience, Manuel has extensively dealt with complex, high-risk jurisdictions.
Before joining Chambers, Manuel worked for many years at WilmerHale in London, where he specialised in international arbitration and public international law. Prior to that, he worked as a judicial fellow at the International Court of Justice in The Hague. Manuel initially qualified and practised in Venezuela.
Manuel is ranked in the leading directories for his main practice areas of public international law, international arbitration, and energy. Because his referees are kind, he is described as “an exceptionally skilled barrister, possessing and extensive knowledge and experience in the PIL and the investment arbitration fields,” as having a “dedication, thoroughness, and work ethic that are truly exceptional,” “writing skills that are unmatched,” and as being “an excellent oral advocate” that is “very commanding on his feet.” For several years, he has been recognised by Lexology as a Future Leader in International Arbitration (being ranked in 2025 as one of the most highly regarded practitioners in the EMEA region) and he has been included twice in The Legal 500’s Arbitration Powerlist.
