From Gaps to Proof: Effective Expert Testimony
In construction disputes, decisions are driven by evidence rather than argument. Experts play a crucial role in bridging the gap between complex project records and clear, reliable conclusions. Their responsibility is not to advocate for a party, but to assist tribunals by providing independent, transparent, and well-reasoned analysis.
- Experts must assist the tribunal, not advocate for the appointing party.
- Reliable analysis must be grounded in documents, data, and tested facts.
- Tools like joint statements and expert conferencing help clarify disagreements.
- Transparency, clear reasoning, and honest concessions strengthen expert authority.
Frequently Asked Questions
Get answers to frequently asked questions about everything we do.
What is the primary role of an expert in construction disputes?
An expert’s primary role is to assist the tribunal by explaining complex technical issues clearly and objectively, not to advocate for the appointing party.
Why is independence important for expert witnesses?
Independence ensures credibility. Tribunals rely more on experts who provide unbiased analysis rather than opinions shaped to support a party’s case.
When should expert evidence be submitted in arbitration?
Expert reports can be submitted with pleadings or later through sequential filing. Sequential filing often produces stronger opinions because more evidence is available.
What is the purpose of expert joint statements?
Joint statements help identify agreed facts, clarify areas of disagreement, and reduce duplication during hearings, making the arbitration process more efficient.
What is witness conferencing in arbitration?
Witness conferencing (often called “hot-tubbing”) allows experts to discuss technical issues together before the tribunal, helping clarify differences in professional judgment.
What are common credibility mistakes experts should avoid?
Experts may lose credibility if they show partisanship, ignore contrary evidence, blur facts with assumptions, or present overly certain conclusions without proper support.
