Comment
"The mandate is the order that gives authoritative notice to the trial court that the judgment appealed from has been reversed or affirmed, as the case may be. The general rule is that the date of the mandate, not the date of the issuance of the decision, is the effective date of an appellate court's decision, that the mandate is the order and that the court's opinion merely gives the reason supporting the order."
