In what circumstances will a court reverse a judgment in a personal injury case?

In reviewing the record for substantial evidence, if the evidence reasonably justifies the jury's factual findings and inferences necessarily drawn, the reviewing court may not reverse the judgment merely because it may be reconciled with different inferences or contrary findings. (People v. Perez (1992) 2 Cal.4th 1117, 1124.) Instead, we "resolve all conflicts in favor of the judgment and indulge all reasonable inferences from the evidence in support of the judgment." (People v. Villalobos (2006) 145 Cal.App.4th 310, 321-322.)
