Civil Procedure
Section 6. Review discretionary. - A review is not a matter of right, but of sound judicial discretion, and will be granted only when there are special and important reasons thereof. The following, while neither controlling nor fully measuring the court's discretion, indicate the character of the reasons which will be considered:
(a) When the court a quo has decided a question of substance, not theretofore determined by the Supreme Court, or has decided it in a way probably not in accord with law or with the applicable decisions of the Supreme Court; or
(b) When the court a quo has so far departed from the accepted and usual course of judicial proceedings, or so far sanctioned such departure by a lower court, as to call for an exercise of the power of supervision. (4a)
