How have courts treated the statement of the case in the opening brief of a personal injury case?

4 Appellant implies in the "Statement of the Case" portion of its opening brief that the evidence was insufficient to sustain the jury's finding, and that the trial court ruled incorrectly regarding the insurance evidence that was presented to the jury. As these contentions are not supported by argument or citation of authority, they are deemed without foundation and must be treated as abandoned. (Rossiter v. Benoit (1979) 88 Cal.App.3d 706, 152 Cal.Rptr. 65.)
