Twenty Essex is praised as a ‘top player across commercial arbitration’ and are highly regarded for their expertise in maritime, trade and international public law matters. Both silks and juniors alike are highly experienced appearing in arbitrations under all major institutions, including, but not limited to ICC, SIAC, UNCITRAL and LMAA. Members of the set additionally have a strong track record acting on both sides of investor state disputes, recently Lord Verdirame KC and Philip Riches KC led Jonathan Ketcheson, Kate Parlett and Sam Goodman in the long-running Diag Human v Czech Republic, in which the team continues to represent Diag Human and Josef Strava in the commercial court addressing various challenges against the high value award issued in 2008. Angharad Parry KC was made silk in 2025 and has a strong track record in arbitrations concerning jurisdictional issues. The set is well-connected in Asia, with a Singapore office; Nakul Dewan KC added English and Welsh silk to his prior Indian senior advocate designation in 2025.
