Nicholas Moussas

Nicholas is the Managing Partner of the Firm. With over 33 years of experience he is one of Greece’s best-known practitioners. He specializes in the areas of litigation/dispute resolution, banking, finance and energy, with an emphasis on corporate finance, securities, regulatory work, EPC projects, commercial transactions and real estate.

Nicholas is a prominent lawyer and litigator and represents or advises clients such as Volkswagen AG, AUDI AG, SEAT S.A., Siemens AG, Heinz, Anheuser Busch Inbev, Nielsen companies and the Mytilineos Group in several high-profile transactions or landmark disputes before the higher courts and arbitration tribunals.

He has recently added to his track record successful results in energy related disputes, acting on behalf of steel and aluminum industrials as well as natural gas downstream clients; he has also been handling major international arbitration cases, involving state -investor investment disputes (BIT disputes).

Within the last six years he has built an impressive track record of successful results in energy related disputes, acting on behalf of steel and aluminum industrials as well as natural gas downstream clients; he has also been handling arbitration cases under the ICC and the UNCITRAL Arbitration Rules as well as international arbitration cases involving investor-state disputes (BIT disputes).

A recent highlight of Nicholas’ track record is the successful representation of Mytilineos Holdings in a bilateral investment treaty dispute against Serbia under the UNCITRAL Arbitration Rules. The dispute related to an investment in state-owned RTB BOR, one of the largest metallurgical and mining complexes for copper extraction and production on a global basis. Moussas & Partners together with other international law firms represented the Greek conglomerate in this landmark case where the Tribunal ordered Serbia to pay to Mytilineos compensation in the area of US$40 million.

Furthermore, Nicholas holds the position of General Counsel to the Hellenic Deposit and Investment Guarantee Fund since 1997. From this position, he is able to closely follow the legal developments in the banking and capital markets industry and has been a contributor to the reform of the deposit insurance and credit institution resolution legislation in the current economic crisis in cooperation with the representatives of the IMF/EU/ECB. He and the banking team advised an international investment bank as Tender Advisor to a Voluntary Tender Offer launched by the largest Greek bank to acquire all outstanding stock of another major credit institution, in what was described as a banking mega-deal for Greek standards

Nicholas is also included in the exclusive panel of arbitrators of the Regulatory Authority for Energy (RAE), the apposite administrative authority for energy in Greece. See more at:
