Research Group on Arbitrator Immunity
Background
In October 2021, the International Council for Commercial Arbitration (ICCA) approved the creation of a new research group to study questions regarding arbitrator immunity and liability in international arbitration. Inspiration for the project came from Governing Board member Loretta Malintoppi’s seminal article, “Don’t Shoot the Sheriff: the Threat of Legal Claims Against Arbitrators and Arbitral Institutions” (Arbitration International, 2021), prompting the research group to explore these crucial questions.
Goals
The primary goal of the Arbitrator Immunity Research Group is to study questions of arbitrator liability and immunity, and to raise practitioners' and arbitrators' awareness of the current legal landscape. The project's goals include investigating the limits of arbitrator immunity, evaluating the effectiveness of language limiting arbitrator liability in procedural orders and institutional rules, and examining the impact and limitations of professional indemnity insurance.
Project Leadership and Acknowledgments
The Research Group is comprised of three Co-Chairs: Kate Brown de Vejar (Partner and Global Co-Chair of International Arbitration at DLA Piper and ICCA Governing Board Member), Victoria Shannon Sahani (Professor of Law at Boston University School of Law), and Damien Nyer (Partner at White & Case).
The Research Group has been supported by the ICCA Bureau, including Lise Bosman, Adam Jankowski, Siri Lundqvist and Azul Martina Navarro, with earlier contributions by Lisa Bingham.
The Research Group expresses profound gratitude to all of the dedicated jurisdiction respondents. Their diligent research, thoughtful responsiveness, and invaluable local expertise made this project possible. The Group is appreciative of the time, care, and professional judgment that each respondent brought to this collaborative effort. Those contributors who have chosen to be identified by name are listed in a dedicated tab on this website.

Methodology
The Research Group began by conducting a literature review and background research on arbitrator liability and immunity. They also consulted with experts who have published work on this topic or were familiar with cases relevant to the research. Next, the team decided to conduct a comprehensive survey of existing laws, cases, and practices as the most effective way to gather information efficiently, including source citations. They chose to survey a representative sample of jurisdictions rather than administer the survey broadly, for practical and logistical reasons.
To understand the current global landscape of arbitrator immunity, the Research Group designed a detailed survey and selected sample jurisdictions for inclusion. They identified 28 jurisdictions to survey, aiming to compile a broad overview of the international legal landscape regarding arbitrator liability and immunity. The initial list of jurisdictions included Australia, Belgium, Brazil, the British Virgin Islands, Canada (including Quebec, separately), China, England, France, Germany, Hong Kong, India, Indonesia, Japan, Malaysia, Mexico, Morocco, Mozambique, Peru, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Thailand, the United Arab Emirates, the United States (including individual states), and Vietnam.
The Research Group compiled a list of survey respondents for each jurisdiction by seeking recommendations for responsive, high-quality contributors who had previously participated in ICCA research projects, as well as recommendations from arbitral institutions and colleagues in the international arbitration community. The survey respondents were sent the survey questions in May 2025 and by Q3 of 2025, the research team had received initial survey responses. After receiving the completed surveys, the research team collaborated with the respondents in two rounds of edits to improve clarity, understanding, and formatting. By March 2026, the team received revised and final survey responses for 15 jurisdictions.
Survey Topics
See the original survey questions.
The original survey questions are also available on this website. In summary, the survey covers several key topics, including:
-
Definitions and General Duties: The survey asks about the ethical standards, duties of care, and general principles of arbitrator liability.
-
Limitations of Liability: The survey explores the existence of general arbitrator immunity, statutory limitations on personal civil liability, and exceptions for misconduct such as bad faith or negligence. The survey further investigates the effectiveness of limitation of liability and indemnity clauses found in arbitral institution rules, procedural materials, and arbitration agreements.
-
Subpoenas and Evidence: The survey questions whether immunity permits an arbitrator to refuse to serve as a witness or provide documents when compelled by a judicial authority.
-
Professional Indemnity Insurance: The survey asks about mandatory insurance requirements, and whether the policies of law firms or barristers' chambers cover activities undertaken as an arbitrator (including coverage for cybersecurity and data privacy breaches).
-
Institutional Involvement and Procedural Issues: The survey examines instances where parties sued arbitral institutions alongside arbitrators, objections to improper forum or venue, and the consequences of unsuccessful or frivolous suits.
Publication of Raw Data
The Research Group and ICCA have decided to publish the survey responses on this website as raw data, without conducting any analysis, comparison, or synthesis. Neither the Research Group nor ICCA expresses views or opinions regarding the content of the survey responses. The goal is to provide primary data on the current landscape in these jurisdictions, allowing practitioners, researchers, and arbitrators to review the findings and draw independent conclusions based on the direct survey responses from the respondents.

Analysis of Professional Indemnity Policies
In addition to publishing these survey responses, the Research Group designated a second work stream to collect and analyze relevant provisions from professional indemnity policies to further assess insurance coverage for arbitrators. This work stream is ongoing.
