How loss of profits expert evidence standards differ by forum — critical for report structure and disclosure.
Arbitration & Court Standards
- Can you provide a loss of profits expert for ICC arbitration?
- Yes. Loss of Profits Expert provides independent expert witnesses for ICC international arbitration proceedings. Expert reports are prepared in accordance with ICC Rules of Arbitration and the IBA Rules on the Taking of Evidence in International Arbitration. Our experts are experienced in producing reports for international arbitration that meet the evidentiary standards and procedural requirements of the ICC and other international arbitration institutions.
- How do CPR Part 35 and Daubert differ for loss of profits experts?
- Under CPR Part 35 (England & Wales), the expert's overriding duty is to the court; reports must disclose instructions, methodology, and the substance of material assumptions. Under FRE Rule 702 / Daubert (United States), the court acts as gatekeeper — expert testimony must rest on sufficient facts, reliable principles, and reliable application. Both require transparent, defensible methodology; the disclosure and admissibility frameworks differ.
- What do the IBA Rules require of a loss of profits expert?
- Under the IBA Rules on the Taking of Evidence in International Arbitration, party-appointed and tribunal-appointed experts typically produce reports that set out instructions, documents relied upon, methodology, assumptions, and conclusions. Experts may be examined at hearing. Loss of profits reports in ICC, LCIA, SIAC and similar forums are commonly prepared with IBA Rules in mind alongside the applicable institutional rules.
