What is the test for reversal of a judgment in a personal injury case?

Cal. 142, 145-146; CALCRIM No. 223.) "Conflicts and even testimony which is subject to justifiable suspicion do not justify the reversal of a judgment, for it is the exclusive province of the... jury to determine the credibility of a witness and the truth or falsity of the facts upon which a determination depends." (People v. Maury (2003) 30 Cal.4th 342, 403; see also People v. Holt (1997) 15 Cal.4th 619, 668 [if record justifies jury's findings, opinion of reviewing court that circumstantial evidence might also be reasonably interpreted to support a contrary result does not warrant a reversal].)
