Tax-related Measures in Investor-State Arbitration

Tax-related Measures in Investor-State Arbitration

London, UK
Signature Event

Wilmer Cutler Pickering Hale and Dorr LLP and the Investment Treaty Forum (ITF) at the British Institute of International and Comparative Law (BIICL) will host the launch of a new study on tax-related measures in investor-State arbitration. This launch event will include a panel discussion on the themes and conclusions of the report, followed by a drinks reception.

The event will be held in WilmerHale's office in Park Lane, London W1. 


The report has been co-authored by Danielle Morris, International Arbitration Partner at WilmerHale in Washington DC, and Professor Yarik Kryvoi, Senior Fellow in International Economic Law and Director of ITF, both of whom will feature in the panel discussion.

The authors will be joined on the panel by Dr. Claudia Annacker, Partner at Dechert; Professor Robert Danon, Professor of Swiss and International Tax Law at the University of Lausanne; and WilmerHale Senior Associate Sam Winter-Barker.

The Report

In contrast to the existing literature, the authors have taken an empirical approach to assess various aspects of tax-related disputes: the geographic origins of claimants and respondent States, the economic sectors involved, the types of measures challenged, and the likelihood of success, among others.

Much of this report presents the findings of an empirical analysis of 62 investor-State treaty disputes and 21 contractual tax-related disputes. In addition to painting a bigger picture of tax-related disputes and identifying patterns in tribunals' decision-making, the report discusses specific treaty provisions that give rise to tax disputes.

WilmerHale and BIICL hopes that the report will help those working in the field of investor-State arbitration to better understand the key statistical trends and patterns of decision-making. At the same time, the report may help those involved in reforming the system of investor-state dispute resolution or investment treaties.
