Dispute Resolution


Marchenko Partners helps multinational companies to resolve their vital regulatory and commercial disputes at the crossing of national and international laws and regulations, government relations, and public policy considerations.

In Dispute Resolution we are dedicated to the practice of Public International Law. Specifically, we focus on:


  • Arbitration & ADR;
  • Investor-State Disputes and Negotiations;
  • WTO and International Trade Law;
  • Commercial, Regulatory and Tax Litigation.


We handle more investor-state disputes against Ukraine than any other national or international law firm. We effectively employ investor-state disputes settlement (ISDS) mechanisms under bilateral and multilateral investment treaties to resolve major regulatory and legal issues, including denial of justice cases, which negatively affect the legitimate interests of multinational companies operating in Ukraine.

We effectively employ ISDS instruments at the early stages of investor-state conflicts to prevent or resolve them amicably. We represent Clients, with outstanding success rate, in regulatory, financial and other disputes, which often involve high stake public policy issues, at the crossing of national and international laws and government relations.
