Giorgio Mandelli is a partner in King & Spalding’s International Arbitration Practice Group, based in London.
Giorgio’s practice focuses on complex, high-value international dispute resolution. He specialises in international arbitration (both commercial and investment arbitration), with a particular focus on representing companies and investors in disputes in the energy and natural resources, financial services and aviation sectors. He has acted as counsel and advocate before ad hoc and institutional international arbitration tribunals, including under the ICC, ICSID, ICSID Additional Facility, DIFC-LCIA, SIAC, SCC, LCIA and UNCITRAL Rules.
Most recently, Giorgio has worked on a number of high-profile commercial arbitrations and investment disputes involving African, European, Latin American and Middle Eastern States, arising variously under international investment agreements and treaties, foreign investment laws and contracts. Additionally, Giorgio provides counsel on public international law matters, including advising States on jurisdictional immunity issues in the context of judicial proceedings before European courts, and he has delivered practical training in public international law to lawyers from various ministries of States in the Middle East and Africa. Currently, Giorgio also is sitting as a party-appointed arbitrator in a Stockholm Chamber of Commerce investor-State arbitration.
Giorgio is qualified as a solicitor-advocate in England and Wales and admitted to practice in New York. He was “recommended” by The Legal 500 2014 (Latin America) and described as a “rising star” in the GAR 100 (9th, 10th and 11th editions). He was included in Who’s Who Legal’s inaugural listing of the “Future Leaders of International Arbitration – Partners” (2017) and, again, in 2018. He also was mentioned as “highly rated” for public international law and international arbitration by The Legal 500 UK 2017; a “name to note” in public international law and international arbitration by The Legal 500 UK 2019; noted for international arbitration in The Legal 500 UK 2020. Giorgio has been included in the 2023 Lawdragon 500 Leading Global Litigators Guide and in the 2024 Lawdragon 500 Leading Global Litigators Guide.
Giorgio is a regular speaker at conferences on topics of public international law and international dispute resolution and writes frequently on international investment law and arbitration. Most recently, Giorgio spoke on “Rush to Judgment: Speed v Fairness in Emergency Arbitration Proceedings” at the ArbIt (Italian Forum for Arbitration and ADR) Conference in Milano.
