Multinational law firm Pinsent Masons has hired partner Sylvia Tonova to the firm’s International Arbitration Practice.
Sylvia is a highly experienced international arbitration lawyer and has extensive experience in both international commercial and investment treaty arbitration focussing on complex, high-value disputes, often in the context of high-profile and politically sensitive projects and transactions. Sylvia will co-lead the firm’s investor-state dispute settlement and public international law team.
She is dual qualified in England and the US (New York and Washington DC). Sylvia represents clients under all the major arbitration rules and advises clients on investment treaty disputes, sovereign immunity, and managing political risk.
Sylvia joins from Jones Day where she has led on arbitrations in Europe, the Middle East, Africa, Latin America, and Asia. She also sits as an arbitrator and was appointed to the ICSID Panel of Arbitrators for a six-year term in 2016.
Jason Hambury, global co-head of Pinsent Masons’ International Arbitration Practice, said: “Sylvia’s skillset is a perfect fit with our leading arbitration practice. Our clients will benefit from her experience working on complex cross-border commercial and investor-state disputes, across numerous sectors, such as energy, mining and telecoms. Sylvia will play a significant role in the continued success of our practice and we are delighted to welcome her.”
Sylvia has been recognised in Legal 500, Who’s Who Legal and Chambers as being a leading individual in international arbitration.
Sylvia said of her appointment: “I am thrilled to join Pinsent Masons and co-lead the investor-state dispute settlement and public international law team. Investment treaty law plays a pivotal role in the political risk strategy of cross-border investors, particularly in the energy, mining and infrastructure sectors. I look forwarding to helping clients resolve their politically sensitive disputes and joining a team highly regarded for its deep sector knowledge and world-class reputation in handling high-value, complex arbitrations.”
