People

Steven Finizio helps clients resolve high-stakes international disputes, including arbitration, investment treaty claims, and related proceedings across multiple jurisdictions. He advises on complex cross-border disputes arising from investments, joint ventures, and commercial arrangements, including public international law and treaty-based disputes involving sovereign states and state-owned entities, helping clients manage legal risk and protect commercial outcomes.

Steven advises businesses and investors on resolving complex disputes, contractual breakdowns, regulatory challenges and geopolitical risk while protecting commercial objectives. He represents clients in a range of proceedings, including arbitrations, expert determinations and mediation, often involving parallel proceedings and competing stakeholder interests.

Across sectors, including energy, infrastructure, financial services, telecommunications and manufacturing, Steven advises clients under major arbitral rules and in disputes governed by laws across Europe, Asia, Africa, South America, and the United States, as well as under bilateral and regional investment treaties.

He regularly acts in disputes arising from energy and infrastructure contracts, M&A transactions, long-term supply contracts, shareholder arrangements and technology licensing requiring coordinated strategies across multiple proceedings and stakeholders. He also acts as arbitrator, including as presiding, sole and party-appointed arbitrator under institutional and ad hoc rules.

A significant part of Steven’s practice involves public international law, treaty-based disputes, and matters involving state-linked entities, including expropriation, changes in law and contractual disruption --- often where legal, political and commercial considerations intersect. He has represented clients before international courts, including the European Court of Human Rights, and contributed to arbitration frameworks, including advising a Central European government on drafting new arbitration legislation. Steven was part of the team that won a landmark decision in the first freedom of expression case in the African Court on Human and Peoples’ Rights.

Steven is active across leading arbitration institutions and academic forums, with roles at arbitral institutions and senior academic appointments, as well as editorial, teaching, and speaking engagements reflecting his contribution to the development of international arbitration.
