Essex Court Chambers ‘stands at the very pinnacle of the English commercial Bar, particularly for complex international disputes’. Paul McGrath KC is acting for the claimants in Petersen & Ors v Republic of Argentina, concerning the enforcement of a $16.4bn judgment issued against Argentina in New York arising from a dispute over an alleged breach of contract. Joe Smouha KC ‘is able to combine a ferocious intellect with steely determination and a thoroughly charming personality’. In March 2025, the senior end of chambers was bolstered by the elevation of the ‘robust, hard-working, and effective’ Ciaran Keller KC and the ‘incredibly bright, creative and methodical’ Anton Dudnikov KC to silk.
