Mass. Gen. Laws ch. 231 § 6G
Any party aggrieved by a decision on a motion pursuant to section six F may appeal as hereinafter provided. If the matter arises in the superior, land, housing or probate court, the appeal shall be to the single justice of the appeals court at the next sitting thereof. If the matter arises in the appeals court or before a single justice of the supreme judicial court, the appeal shall be to the full bench of the supreme judicial court. The court deciding the appeal shall review the finding and award, if any, appealed from as if it were initially deciding the matter, and may withdraw or amend any finding or reduce or rescind any award when in its judgment the facts so warrant.
Any party may file a notice of appeal with the clerk or register of the court hearing the motion within ten days after receiving notice of the decision thereon. The clerk or register shall then forward the motion, the court's findings and award, and any other documents relevant to the appeal to the clerk of the court deciding the appeal who, upon receipt thereof, shall refer the matter to the court for speedy decision and shall notify the parties of such decision, which shall be final. Any appeal to the supreme judicial court or the appeals court shall proceed according to the Massachusetts Rules of Appellate Procedure; any appeal to a single justice of the Appeals Court shall proceed under the rules for the regulation of practice before a single justice of that court. The payment of any award made pursuant to section six F shall be stayed until the completion of all appeals relating to the civil action in which the award was made.
