(a) What May Be Reviewed. A party may seek discretionary review by the Supreme Court of any decision of the Court of Appeals which is not a ruling including:
(1) Decision Terminating Review. Any decision terminating review.
(2) Interlocutory Decision. Subject to the restrictions imposed by rule 13.5(b), any interlocutory decision, including but not limited to (i) a decision denying a motion to modify a ruling of the commissioner or clerk which denies a motion for discretionary review, and (ii) if the clerk refers a motion for discretionary review to the court, a decision by the court which denies a motion for discretionary review.
(b) Decision Terminating Review. A party seeking review of a Court of Appeals decision terminating review may first file a motion for reconsideration under rule 12.4 and must file a "petition for review" or an "answer" to a petition for review as provided in rule 13.4.
(c) Interlocutory Decision. A party seeking review of an interlocutory decision of the Court of Appeals must file a "motion for discretionary review" as provided in rule 13.5.
(d) Incorrect Designation of Motion or Petition. A motion for discretionary review of a decision terminating review will be given the same effect as a petition for review. A petition for review of an interlocutory decision will be given the same effect as a motion for discretionary review.
(e) Ruling by Commissioner or Clerk. A ruling by a commissioner or clerk of the Court of Appeals is not subject to review by the Supreme Court. The decision of the Court of Appeals on a motion to modify a ruling by the commissioner or clerk may be subject to review as provided in this title.
