Mr. Harris acted as an expert witness in an ICC dispute involving a large power and water production plant in the Middle East. The work involved testimony on the financial effects of various delays which the project experienced, including a quantification of the effect of an alleged delay in refinancing on the value of the project. Mr. Harris also analysed the reasonableness of a claim by the offtaker that the plant’s tariff should be reduced because of alleged non-conformity with the contract specifications. The case involved written and oral testimony. The claims and counter claims were in the order of US$200-300 million.
