Expert witnesses play a key role in litigation, especially when dealing with construction issues. The testimony of an expert at trial can be a deciding factor in helping persuade a jury or judge in your client’s favor. Thus, it is imperative that your expert’s opinion meet the proper legal standard.

In Polaris Engineering, Inc. v. Texas International Terminals, LTD, the United States District Court for the Southern District of Texas reiterated the importance of an expert’s opinion complying with the applicable legal standards governing expert testimony. 2023 U.S. Dist. LEXIS 109413 (S.D. Tex. June 26, 2023).

The legal standard at issue in Polaris was Rule 702 of the Federal Rules of Evidence. Polaris involved a suit arising from a contract related to the design, engineering, and construction of a terminal and crude-oil processing facility for Texas International Terminals in Galveston, Texas. There were four separate contracts that governed the Project. One of the contracts governed the creation of the 50,000 barrel per day crude processing unit. Because the parties wanted to move quickly, they agreed to certain assumptions about the Project and specifically designed a change order process whereby the price and schedule could be adjusted if the agreed upon assumptions were incorrect.
