Heading: GTT’s Expert’s Testimony

Text: The district court found that it properly allowed testimony by GTT’s damages expert at trial. We review the admission of expert testimony under the law of the regional circuit—here, the Eighth Circuit. Ericsson, 773 F.3d at 1225. The Eighth Circuit reviews the admission of expert testimony for abuse of discretion. Bonner v. ISP Techs., Inc., 259 F.3d 924, 928 (8th Cir. 2001). On appeal, Appellants argue that the district court breached its gatekeeping obligation under Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), by failing to exclude GTT’s damages expert’s trial testimony. Appellants contend that GTT’s expert failed to consider price elasticity in his testimony at trial, providing no economic evidence to support his theory. That is not so: GTT’s expert did testify to price inelasticity at trial. See J.A. 2100, 2102. As GTT points out, moreover, GTT’s expert’s testimony was based on the analysis in his expert report, which elaborated on price elasticity. Appellants do not argue that GTT’s expert departed from the methodology described in his report, or that the methodology in his report was improper. Appellants had the opportunity to cross-examine GTT’s expert and could have asked him about price elasticity at trial. We, therefore, affirm the district court’s denial of Appellants’ motion for JMOL regarding the exclusion of GTT’s damages expert’s testimony.
