Benjamin Siino is a founding partner of Gaillard Banifatemi Shelbaya Disputes and is recognized as “one of the best French experts in enforcement of arbitral awards”. He previously was a partner at Shearman & Sterling LLP where he practiced for more than ten years.
His experience includes international ad hoc arbitrations, including under UNCITRAL Rules, and institutional arbitrations under the Rules of the ICC and ICSID, with a strong focus on energy, investment and general commercial arbitrations, as well as arbitrations related to Africa. He notably was part of the team that secured a landmark victory on behalf of Algeria in a dispute with Orascom TMT, where the Tribunal dismissed USD 4 billion claims brought by Orascom TMT.
Benjamin also acts as counsel in arbitration-related and other litigation proceedings, with a focus on proceedings to seek recognition and enforcement of arbitral awards and foreign judgments. Among such proceedings, Benjamin leads and coordinates global enforcement efforts across multiple jurisdictions in relation to the USD 50 billion award secured by our team on behalf of the majority shareholders of the former Yukos Oil Company in three investment arbitrations against the Russian Federation arising from the expropriation of our clients’ assets in Yukos.
Benjamin develops and implements asset tracing strategies to identify and locate recoverable assets worldwide, through the most complex money laundering schemes and corporate structures. He has extensive experience in cross-border cases and has traced assets in all shapes and sizes.
Benjamin is featured in Chambers Global and in Who’s Who Legal: Arbitration. The publication notes that Benjamin is a “brilliant advocate“, “extremely hard working and sharp”, and “clearly a leader in the field”. Previous editions have highlighted that he is “one of the top few to perfectly master judicial and arbitral questions”, and “a true expert in the field of recognition and enforcement of arbitral awards”.
