(a) Courts Other Than District Court. The court, after verdict or after a finding of facts under Rule 52, may report the case for determination by the appeals court. If the trial court is of opinion that an interlocutory finding or order made by it so affects the merits of the controversy that the matter ought to be determined by the appeals court before any further proceedings in the trial court, it may report such matter, and may stay all further proceedings except such as are necessary to preserve the rights of the parties. The court, upon request of the parties, in any case where the parties agree in writing as to all the material facts, may report the case to the appeals court for determination without making any decision thereon. In an action commenced before a single justice of the supreme judicial court, the court may report the case in the circumstances above described to either the appeals court or the full supreme judicial court; provided further that a single justice of the supreme judicial court may at any time reserve any question of law for consideration by the full court, and shall report so much of the case as is necessary for understanding the question reserved.
(b) District Court. Report of a case or a ruling by the court to the Appellate Division shall be governed by District/Municipal Courts Rules for Appellate Division Appeal 5.
