Viren MascarenhasKing & Spalding LLP

King & Spalding LLP fields ‘an extraordinary arbitration team’, with recent work shows its strengths across a range of commercial and investment arbitration work, as well as arbitration-related litigation. The group’s ability to act worldwide is enhanced by the firm’s global network and the arbitration experience of its counterparts spread across 17 offices worldwide. In Houston, the team is routinely involved in disputes relating to large projects in the oil and gas industry; John Bowman is a well-known name in this space, as is Reginald Smith, whom clients have singled out as ‘vigilant, courteous, and persuasive‘. The group has a strength in energy disputes across the board, but also acts for leading construction, manufacturing, transport, telecoms, and hospitality companies. Further, demonstrating its ability to represent individual investors equally well, the team recently secured a $45m award for Dutch national Trinh Vinh Binh in an arbitration initiated under the Arbitration Rules of the United Nations Commission on International Trade Law (UNCITRAL) against the Socialist Republic of Vietnam; at the time of writing, this victory marks the largest compensation for moral damages awarded to an individual investor to date. Also recommended is New-York based Viren Mascarenhas, who represented the UK claimants in a £3bn UNCITRAL arbitration against Uruguay. The department is led by Edward Kehoe and Doak Bishop, based in New York and Houston, respectively. The group’s French language arbitration offering was somewhat weakened with the departure of Caline Mouawad to dispute resolution boutique Chaffetz Lindsey LLP in December 2019.
