When last we visited this issue, a three-member panel of the Court of Appeals said that, based on a precedential opinion with which they disagreed, the referendum on Michigan's Emergency Manager Law qualifies for the ballot, but they stayed that decision pending a poll of their fellow judges on the question of convening a special panel to pursuant to MCR 7.215(J)(3)(a). See Stand Up For Democracy v. Sec'y of State and Board of State Canvassers (PDF).Today, the Court of Appeals has declined to convene the special panel. Nothing yet on an appeal to the Supreme Court...
Here's the pertinent text of the MCR 7.215:
(J) Resolution of Conflicts in Court of Appeals Decisions.
(1) Precedential Effect of Published Decisions. A panel of the Court of Appeals must follow the rule of law established by a prior published decision of the Court of Appeals issued on or after November 1, 1990, that has not been reversed or modified by the Supreme Court, or by a special panel of the Court of Appeals as provided in this rule.
(2) Conflicting Opinion. A panel that follows a prior published decision only because it is required to do so by subrule (1) must so indicate in the text of its opinion, citing this rule and explaining its disagreement with the prior decision. The panel's opinion must be published in the official reports of opinions of the Court of Appeals. (3) Convening of Special Panel. (a) Poll of Judges. Except as provided in subrule (3)(b), within 28 days after release of the opinion indicating disagreement with a prior decision as provided in subrule (2), the chief judge must poll the judges of the Court of Appeals to determine whether the particular question is both outcome determinative and warrants convening a special panel to rehear the case for the purpose of resolving the conflict that would have been created but for the provisions of subrule (1). Special panels may be convened to consider outcome-determinative questions only. (b) Effect of Pending Supreme Court Appeal. No poll shall be conducted and a special panel shall not be convened if, at the time the judges are required to be polled, the Supreme Court has granted leave to appeal in the controlling case. (c) Order. Immediately following the poll, an order reflecting the result must be entered. The chief clerk of the Court of Appeals must provide a copy of the order to the Clerk of the Supreme Court. The order must be published in the official reports of opinions of the Court of Appeals.
(4) Composition of Panel. A special panel convened pursuant to this rule consists of 7 judges of the Court of Appeals selected by lot, except that judges who participated in either the controlling decision or the opinion in the case at bar may not be selected.
