About Us

Investment Arbitration Reporter is a news and analysis service focusing on the international law that applies to foreign investment, particularly the international treaties and arbitration claims that arise in this context.

We offer detailed and nuanced coverage, with a particular focus on investigation of unreported cases and comprehensive review and discussion of legal documents and important policy developments.

In addition to reaching a large and diverse subscriber base, our original reporting often inspires follow-up coverage by mainstream media publications.

“Luke Eric Peterson is the world’s leading journalist writing about investment law and policy. His Investment Arbitration Reporter service is an invaluable tool which I use to keep track of the latest developments and trends in the field of investment law and policy. I often recommend it to my academic colleagues, my students, and to practitioners.”
Christoph Schreuer, former Professor of International Law, University of Vienna; Author of The ICSID Convention: A Commentary (Cambridge University Press)

Investment Arbitration Reporter provides reliable and impressively timely information on investor-state arbitrations – including otherwise unpublicized non-ICSID cases. Thanks to the long experience and expertise of its editor, Luke Eric Peterson, the service offers not merely case summaries but also useful insights and analysis on recent developments in this rapidly growing and important field.”
Antonio Parra, former Deputy Secretary General, International Centre for Settlement of Investment Disputes (ICSID)

“It is increasingly difficult to stay on top of the latest developments in investor-state arbitration given the growing numbers of decisions and awards. Investment Arbitration Reporter is an essential tool for those in academia, government or private practice, since it provides excellent summaries of published and unpublished cases, as well as very useful and up to date information and analysis”.
Ignacio Suarez Anzorena, former Lead Counsel with Argentine Government’s investor-state arbitration claims division

Investment Arbitration Reporter’s work is unrivaled. Mr. Peterson’s reporting was especially useful for me when I was working to improve Japan’s investment treaty model. In several instances, decisions by the Government to pursue particular negotiating strategies were influenced by lessons learned from Mr. Peterson’s reporting and analysis.”
Miyake Yasujiro, Japanese Ministry of Economy, former Investment Treaty Negotiator

“Astute analysis and measured commentary on a complex and opaque area of international law.  Investment Arbitration Reporter is a valuable resource for understanding the public policy implications of international commercial disputes.”
Matthew Sanger, Senior Advisor, International Affairs Directorate, Health Canada, Canadian Government

“Luke Peterson doesn’t just cover arbitrations. He uncovers them.”
Michael Goldhaber, Senior International Correspondent, The American Lawyer magazine
