Between Advocacy and Neutrality: Role of Legal Expert Witnesses in International Construction Disputes

Ahmed Yahya El Sayed, Hazem Ashraf Abotaleb, Hazem Khaled Aboulata Mohamed and Ola D. Elmonayeri

How legal expert witnesses help tribunals prove foreign law in international construction disputes, and what makes a tribunal rely on their evidence. The paper compares party-appointed and tribunal-appointed experts.

Legal experts interpret foreign law, clarify contract ambiguities and give the tribunal an evidential basis for its decision.
Tribunals rely on testimony that is clear and coherent, from an expert seen as credible and neutral.
A balanced or hybrid approach to appointing experts works best for proving foreign law.

Translating Complexity into Credible Evidence: Quantum Expert Witnesses in Construction Disputes Arena

Ahmed Yahya El Sayed, Hazem Ashraf Abotaleb, Hazem Khaled Aboulata Mohamed and Ola D. Elmonayeri

The role of quantum experts in valuing works, prolongation and disruption costs and other losses, and why the way a quantum report is built and presented affects the outcome of a claim.

Tribunals look to quantum evidence for clear reasoning as well as accurate figures.
A well-structured quantum report strengthens a claim; a poorly presented one can weaken a strong case.
Quantum assessment involves judgment and assumptions, so the expert's credibility matters as much as the method.

Ahmed Yahya El Sayed, Mohamed Mohsen Ahmed El-Dafrawi, Hazem Khaled Aboulata Mohamed and Ola D. Elmonayeri

A case study of an MEP subcontractor in Saudi Arabia working under an unbalanced subcontract, read alongside Tecnicas Reunidas v Petroleum Chemicals and Mining Company [2025] EWHC 1785 (Comm).

Conflicting contract documents, tight time bars and a contradictory arbitration clause drove the dispute.
Disagreements over the arbitration seat and governing law showed weak communication and little use of ADR.
A proactive contracts team pays for itself across the contract life cycle, starting at tender stage.
