From the MSC Clerk’s Office:
Cases appealed to the Michigan Supreme Court are filed as "applications for leave to appeal." Applications are filed with the Clerk of the Supreme Court in Lansing, during regular business hours.
The Court receives nearly two thousand applications each year. Of that number, the Court "grants" only about a hundred applications. Typically, these are cases that involve interpretation of the Michigan Constitution, an important Michigan statute, or a point of law upon which the courts below are in need of direction.
Of the remaining applications, the great majority are "denied." A denial order normally contains only the explanation that the Justices "are not persuaded that the question(s) presented should be reviewed by this Court." Occasionally a denial order will note that the case is not yet ripe for final disposition. Thus the Justices may state that they are not persuaded that the case should be reviewed before the completion of further proceedings in the lower courts.
A denial order is not a decision to uphold (affirm) the decision made by the lower court. It is simply a decision that the Supreme Court will not hear the case. It does not imply approval or disapproval of what was decided below.
In a small number of cases, the Court will respond to the application with an order that resolves the case, or that directs a lower court to consider the case again in accordance with directions supplied by the Supreme Court.
Applications are decided by the Court on the basis of the written materials submitted by the parties. In some cases, oral argument may be heard on an application.
Because of the large number of applications filed with the Michigan Supreme Court, an application generally remains pending for several months before a decision is reached. However, the time for any particular application can vary greatly, depending on a variety of circumstances. In a true emergency, the Court sometimes acts on an application within hours of its receipt.
If the application is granted, there is further briefing and a hearing (called "oral argument") in the Supreme Court courtroom located on the in the Michigan Hall of Justice located at 925 W. Ottawa St., in Lansing. Parties and amici curiae are strongly encouraged to file their briefs on or before the filing deadlines so that the Court has sufficient time to consider them before oral arguments. Oral arguments are ordinarily heard during the first week of the month, starting in October and continuing until May. These are public hearings, open to all citizens and members of the media.
During the hearing, the Justices sometimes ask questions or offer comments, but the Court will not decide the case during the public hearing. The questions and comments of a Justice do not indicate the manner in which that Justice intends to vote or analyze the case. At the conclusion of the hearing, the case is deemed to have been "submitted" to the Court for decision.
Following the hearing, the Court meets in private to discuss the case and to agree preliminarily on how the case is to be decided. A Justice is selected to author an opinion of law, explaining the Court's decision. When the proposed opinion is written, it is circulated among the Justices. Some agree, some ask for revisions, and some disagree. In response to the proposed opinion, another Justice may write a dissenting opinion or an opinion expressing a separate point of view. During the process, the Justices sometimes change their minds regarding the proper outcome of the case. When each Justice has concurred in the final draft of one of the circulating opinions, the case is decided. All of the grant cases submitted to the Court are expected to be decided by July 31 of each year.
As part of its decision making process, the Michigan Supreme Court considers a wide variety of legal
rules and precedence, including the court rules, rules of evidence, disciplinary rules, administrative orders, state and federal constitutional limitations, and more.
