When an appellate court’s reversal is accompanied by directions requiring specific proceedings on remand, those directions are binding on the trial court and must be followed. Here, the disposition language of the prior appellate decision directed a new trial of damages, which the trial court properly held. The opinion also contained advice on how the trial court should frame special verdicts to avoid problems on the retrial. For some reason the trial court refused to follow these instructions, but defendant, which appealed from the ensuing judgment, was not prejudiced by the trial court’s error, so the judgment against it is affirmed.
