Transparency Uncitral Rules.
1. Background and Purpose
Historically, investment arbitration under United Nations Commission on International Trade Law was:
- Confidential
- Limited to disputing parties
- Lacked public scrutiny
However, because disputes often involve:
- Public funds
- Government policies
- Regulatory actions
Transparency became essential to ensure:
- Legitimacy
- Accountability
- Public trust
2. Scope of UNCITRAL Transparency Rules
The rules apply to:
- Investor-State arbitration under treaties concluded after April 1, 2014
- Older treaties if parties agree or via the Mauritius Convention on Transparency
3. Key Features of Transparency Rules
(A) Publication of Information
The following must be made public:
- Notice of arbitration
- Pleadings and submissions
- Tribunal decisions and awards
This is often done through platforms like the UNCITRAL Transparency Registry.
(B) Open Hearings
- Hearings are generally open to the public
- Can be broadcast or attended
Exception:
- Confidential or sensitive information
(C) Third-Party Participation
(i) Amicus Curiae
Non-disputing parties (e.g., NGOs) can submit briefs.
(ii) Non-Disputing Treaty Parties
States that are parties to the treaty can make submissions.
(D) Exceptions to Transparency
Transparency may be limited to protect:
- Confidential business information
- State security
- Privileged communications
(E) Balance Between Transparency and Confidentiality
The rules strike a balance:
- Promote openness
- Protect legitimate secrecy
4. Legal Significance

- Increase legitimacy of ISDS
- Prevent abuse of arbitration
