We are pleased to present the next instalment in the “Volterra Fietta PIL Commentaries” podcast series

Effective Quantum Strategies for Investors in Investment Treaty Arbitrations

In this commentary, Robert G Volterra explores the strategic considerations involved in pleading quantum damages in investment treaty arbitrations. Drawing on years of practical experience acting for both investors and States, and as an arbitrator in investor-State disputes, Robert examines how parties approach quantum and the factors that can influence a tribunal’s assessment of damages.

Quantum remains one of the most significant and technically complex aspects of investment treaty arbitration. The assessment of damages often has a decisive impact on the outcome of proceedings, requiring parties to balance legal strategy, expert evidence and persuasive advocacy. In this commentary, Robert shares practical insights drawn from decades of experience representing both claimants and respondents, as well as serving as an arbitrator.

The Volterra Fietta PIL Commentaries Series features perspectives from seasoned professionals with unparalleled practical experience. In this series, our partners examine the core concepts, emerging principles and pivotal developments shaping the future of public international law and international dispute resolution.
