Three Crowns, which claims to be  the world's first arbitration law firm, has launced with offices in London, Washington DC and Paris. The new boutique was set up by six leading arbitrators, including three Freshfields Bruckhaus Deringer partners. It will focus on international arbitration including commercial, investment treaty and inter-state. Speaking about Three Crowns, co-founder Petrochilos says the structure of the new firm will allow it to deliver 'sharper focus' and 'hands-on partner involvement from start to finish.'
