How have the courts interpreted a motion for a new trial?

Appellant argues against the soundness of some of the reasons, given above, which the court stated in the order granting the motions for new trial. Whether the subsidiary reasons offered by the judge are valid or not, we need not consider, because a ground stated by the statute, insufficiency of the evidence to support the verdicts (Code Civ.Proc. 657, subd. 6), is specifically set forth in the order. Additional reasoning does not impeach the order. (Yarrow v. State of California, 53 Cal.2d 427, 438-439, 2 Cal.Rptr. 137, 348 P.2d 687.)
