(4) Any matter incidental to the exclusive appellate jurisdiction of the full court for which provision may hereafter be made; and further provided, that no transfer shall be made to any court other than the appeals court of the following:—
(1) Civil actions under section five of chapter two hundred and forty-nine against any court other than the supreme judicial court or the appeals court or a judicial officer thereof;
(2) Stays of execution of sentence after the filing or allowance of exceptions or the entry of an appeal under section four of chapter two hundred and seventy-nine; reductions of bail under section fifty-eight of chapter two hundred and seventy-six; summary review of questions of law pertaining to issuance or denial of preliminary injunctions in labor dispute cases under subsection (6) of section six of chapter two hundred and fourteen; summary review of workers' compensation orders pending appeal under section sixty A of chapter one hundred and fifty-two; suspension, modification or annulment of orders or judgments under section one hundred and seventeen of chapter two hundred and thirty-one pending an appeal; and stays of orders or decrees in equity and other certain matters in the probate court under sections twenty-three and twenty-four of chapter two hundred and fifteen.
