In City of San Antonio v. Pollock, 284 S.W.3d 809, 816 (Tex. 2009), the court explained that "conclusory opinions are legally insufficient evidence to support a judgment even if the party did not object to the admission of the testimony." If "no basis for the opinion is offered, or the basis offered provides no support, the opinion is merely a conclusory statement and cannot be considered probative evidence," regardless of whether an objection has been made. Id. at 818. A conclusory statement of an expert witness is insufficient to create a question of fact to defeat summary judgment. McIntyre v. Ramirez, 109 S.W.3d 741, 749 (Tex. 2003).
