Reversed judgment on the verdict and remand for new trial. Plaintiff brought a personal injury action against Defendant for injuries suffered in a bus accident. The jury found for Plaintiff but awarded minimal damages on the belief from an expert testimony that future surgery would not be required. The court awarded Defendant costs and attorney fees under CCP 998. Plaintiff appealed on the grounds that the expert testimony exceeded the scope of permissible impeachment. The appeals court agreed and ordered the trial court to vacate its order on the post-trial motions.
