Expert witness
Independent expert opinion, grounded in major programme delivery.
Our experts remain professionally active in the sectors in which they give opinion, and accept single-party, joint and tribunal appointments in arbitration, adjudication, litigation and expert determination.
Our expert principles
Every instruction is guided by four principles.
- 01
Independence before advocacy.
- 02
Evidence before assertion.
- 03
Contemporary experience over historic recollection.
- 04
Duty to the tribunal before commercial interest.
