Electronic Briefs in WHIRLPOOL CORPORATION v. CAMACHO     


An expert’s opinion, to be admissible, must be relevant and reliable. Exxon Pipeline Co.
v. Zwahr, 88 S.W.3d 623, 628 (Tex. 2002). To be relevant, the expert’s opinion must be
based on the facts; to be reliable, the opinion must be based on sound reasoning and
methodology. Id. at 629; Merrell Dow Pharms., Inc. v. Havner, 953 S.W.2d 706, 714
(Tex. 1997). We review a trial court’s determination that a witness’s testimony is
unreliable for an abuse of discretion. Helena Chem. Co. v. Wilkins, 47 S.W.3d 486, 499
(Tex. 2001). A trial court abuses its discretion in excluding expert testimony if the
testimony is relevant to the issues in the case and is based on a reliable foundation.
Zwahr, 88 S.W.3d at 628; Helena Chem. Co., 47 S.W.3d at 499.
