SECTION 11. Further appellate review of certain cases by supreme judicial court

There shall be no further appellate review by the supreme judicial court of any matter within the jurisdiction of the appeals court which has been decided by that court, except:—(a) where a majority of the justices of the appeals court deciding the case, or of the appeals court as a whole, certifies that the public interest or the interests of justice make desirable a further appellate review, or (b) where leave to obtain further appellate review or late review is specifically authorized by three justices of the supreme judicial court for substantial reasons affecting the public interest or the interests of justice. Upon the written order of a majority of the justices of the appeals court, the decision of a panel of the appeals court may be reviewed and revised by a majority of the justices of the appeals court. Such a review shall not be a condition precedent to obtaining further appellate review by the supreme judicial court.
