Tribunal Oversight Of Party-Appointed Experts
1. Introduction
In arbitration, parties often appoint their own experts to provide technical, financial, or specialized opinions. While party-appointed experts help present a case, tribunal oversight ensures that the evidence remains reliable, impartial, and procedurally fair.
Tribunal oversight balances party autonomy with the integrity of the arbitral process, preventing experts from acting as advocates rather than neutral advisors.
2. Rationale for Tribunal Oversight
Maintain Fairness and Impartiality:
Experts appointed by a party may be biased; tribunals supervise to ensure neutrality in the presentation of evidence.
Procedural Efficiency:
Tribunal sets timelines for submission, rebuttal, and cross-examination of expert reports.
Quality and Reliability:
Ensures expert opinions are methodologically sound and based on credible data.
Integration with Tribunal-Appointed Experts:
Tribunals may appoint neutral experts or conduct expert conferences to reconcile conflicting party-appointed opinions.
Transparency:
Oversight ensures disclosure of data, assumptions, and methodologies used by experts.
3. Legal and Institutional Basis
