Constantinos Salonidis is a partner with Foley Hoag’s international litigation and arbitration department in Washington, DC. He is dual-qualified in civil law and common law, and is admitted to practise in New York and Greece. His practice focuses on international dispute resolution before the International Court of Justice and arbitration panels administered under the ICSID, UNCITRAL and ICC Arbitration Rules.
Constantinos has significant experience in investment treaty arbitration matters, having represented sovereigns in cases involving a wide array of industries such as automobile manufacturing, banking, cable television services, health insurance, hydrocarbons, mining, port operations, solar power, steel manufacturing and tobacco. He has served as counsel to: Belgium in defeating on jurisdictional grounds a US$2 billion ICSID claim by Chinese insurer Ping An; India, in an UNCITRAL claim brought by French logistics and transport company Louis Dreyfus SAS (India’s very first victory in investment treaty arbitration); Uruguay, in the landmark ICSID case brought by Swiss tobacco company Philip Morris International; Slovakia, in two UNCITRAL arbitrations brought by Austria’s Euram Bank and Dutch insurance company Achmea; and Qatar, in the country’s first ICSID arbitration initiated by Jordanian investors in a cable television franchise. He has also successfully represented in several investment arbitration cases Ecuador, Ukraine and Venezuela, and is currently representing Mauritius in an ICSID arbitration, as well as Greece and India in proceedings under the UNCITRAL Arbitration Rules.
His experience in interstate litigation includes his representation of: Qatar in several cases before the International Court of Justice and other international legal fora arising out of the measures imposed by the UAE, Saudi Arabia, Bahrain and Egypt against Qatar; the Philippines, in the historical arbitral proceeding under Annex VII of the United Nations Convention on the Law of the Sea against China; and Ecuador, in a landmark arbitration proceeding against the US under the state-to-state arbitration provisions of the bilateral investment treaty between the two countries.
Constantinos co-edited Natural Resources and the Law of the Sea (Juris Publishing, 2017) and Canons of Construction and other Interpretive Principles in Public International Law (Kluwer, 2019), the latter of which represents the first modern, free-standing analysis of canons and principles of interpretation beyond the 1969 Vienna Convention on the Law of Treaties. Constantinos has also authored several articles on various topics of public international law, including the law of the sea, international humanitarian law, international criminal law and the sources of international law; and he has lectured on treaty interpretation and international investment law and arbitration at the Graduate Institute of Geneva, the Melbourne School of Law and the Columbia Centre on Sustainable Investment’s executive training programme on investment arbitration. He holds the prestigious diploma in public international law of The Hague Academy of International Law (2006), which is awarded very sparingly. In 2018, Constantinos served as the director of studies in English for the public international law session of the Academy. In 2016, he was appointed to serve on the ICSID panel of conciliators by the Slovak Republic.
