1. In each case determined by opinion by the supreme court or any district of the court of appeals, or finally disposed of by opinion upon a motion, the judicial opinion shall be reduced to writing and filed in the cause. If the decision is not unanimous, the opinion shall show which judge delivered it, and which judges concurred therein or dissented therefrom.

2. The clerk of the appellate court shall, when the opinion of the court is filed in his office, endorse thereon the day on which it is filed, and enter the same on his minutes, and shall, within thirty days thereafter, make a true copy thereof, and shall transmit the same without delay to the trial court.
