Alexander ThompsonTwenty Essex ‘A joy to work with and a fierce intellect.’

Praised as a ‘premier set in shipping and commodities with strength in depth at all levels’, Twenty Essex  supports clients in disputes across the whole gamut of maritime matters. Timothy Hill KC, Alex Carless, and Michal Hain all acted on the CMA CGM Libra, which proceeded to the Supreme Court in 2021 and held that a defective passage plan renders a vessel unseaworthy. Elsewhere, Timothy Young KC acted for the Spanish government in London Steam-Ship Owners’ Mutual Insurance Association Ltd v Spain opposite Alexander Thompson; the case concerns one of the largest oil spills in Europe caused by the sinking of the Prestige off the coast of Galicia in 2002. Henry Byam-Cook KC and Philip Riches KC continue to receive instructions on high-profile disputes, with the former involved in two cases arising out of the insolvency of a trading company and a subsequent ship arrest which will be heard concurrently in the Commercial Court. Oliver Caplin, who specialises in dry shipping, has also had a strong year, including acting as sole counsel against silks.
