Webinar: Effectively Pleading Quantum in International Arbitration

On 28 June 2022, Volterra Fietta hosted a virtual seminar on “Effectively Pleading Quantum in International Arbitration”.

In an investor-State arbitration, it is vitally important to understand the quantum issues as early possible.  The very first pleadings to a Tribunal should set the stage for the debate on losses.  Unfortunately, many practitioners may not be entirely comfortable with this approach.  They are often experienced in constructing arguments and establishing evidence to bring or defend claims of legal breaches.  But they outsource the issue of quantum to experts and thus delay its presentation until the first Memorial or Counter-Memorial.

This underestimates the importance of quantum in any investor-State arbitration.  For investors, the recovery of their damages is the paramount concern – little satisfaction is gained from a moral award that does not adequately compensate loss.  For Respondent States, protecting taxpayers from exaggerated quantum claims is key.  In order to accomplish these goals, practitioners must plead quantum effectively from the earliest stages of the arbitration.

Volterra Fietta’s latest virtual seminar provided an opportunity to discuss the best ways of pleading quantum to an investor-State arbitration tribunal, with some of the most experienced practitioners and experts in the world.
