(A) Preliminary Injunctions.
(1) Except as otherwise provided by statute or these rules, an injunction may not be granted before a hearing on a motion for a preliminary injunction or on an order to show cause why a preliminary injunction should not be issued.
(2) Before or after the commencement of the hearing on a motion for a preliminary injunction, the court may order the trial of the action on the merits to be advanced and consolidated with the hearing on the motion. Even when consolidation is not ordered, evidence received at the hearing for a preliminary injunction that would be admissible at the trial on the merits becomes part of the trial record and need not be repeated at the trial. This provision may not be used to deny the parties any rights they may have to trial by jury.
(3) A motion for a preliminary injunction must be filed and noticed for hearing in compliance with the rules governing other motions unless the court orders otherwise on a showing of good cause.
(4) At the hearing on an order to show cause why a preliminary injunction should not issue, the party seeking injunctive relief has the burden of establishing that a preliminary injunction should be issued, whether or not a temporary restraining order has been issued.
(5) If a preliminary injunction is granted, the court shall promptly schedule a pretrial conference. The trial of the action on the merits must be held within 6 months after the injunction is granted, unless good cause is shown or the parties stipulate to a longer period. The court shall issue its decision on the merits within 56 days after the trial is completed.
(B) Temporary Restraining Orders.
(1) A temporary restraining order may be granted without written or oral notice to the adverse party or the adverse party's attorney only if
(a) it clearly appears from specific facts shown by affidavit or by a verified complaint that immediate and irreparable injury, loss, or damage will result to the applicant from the delay required to effect notice or from the risk that notice will itself precipitate adverse action before an order can be issued;
(b) the applicant's attorney certifies to the court in writing the efforts, if any, that have been made to give the notice and the reasons supporting the claim that notice should not be required; and
(c) a permanent record or memorandum is made of any nonwritten evidence, argument, or other representations made in support of the application.
(2) A temporary restraining order granted without notice must:
(a) be endorsed with the date and time of issuance;
(b) describe the injury and state why it is irreparable and why the order was granted without notice;
(c) except in domestic relations actions, set a date for hearing at the earliest possible time on the motion for a preliminary injunction or order to show cause why a preliminary injunction should not be issued.
(3) Except in domestic relations actions, a temporary restraining order granted without notice expires by its terms within such time after entry, not to exceed 14 days, as the court sets unless within the time so fixed the order, for good cause shown, is extended for a like period or unless the party against whom the order is directed consents that it may be extended for a longer period. The reasons for the extension must be stated on the record or in a document filed in the action.
(4) A temporary restraining order granted without notice must be filed forthwith in the clerk's office and entered in the court records.
(5) A motion to dissolve a temporary restraining order granted without notice takes precedence over all matters except older matters of the same character, and may be heard on 24 hours' notice. For good cause shown, the court may order the motion heard on shorter notice. The court may set the time for the hearing at the time the restraining order is granted, without waiting for the filing of a motion to dissolve it, and may order that the hearing on a motion to dissolve a restraining order granted without notice be consolidated with the hearing on a motion for a preliminary injunction or an order to show cause why a preliminary injunction should not be issued. At a hearing on a motion to dissolve a restraining order granted without notice, the burden of justifying continuation of the order is on the applicant for the restraining order whether or not the hearing has been consolidated with a hearing on a motion for a preliminary injunction or an order to show cause.
(C) Form and Scope of Injunction. An order granting an injunction or restraining order
(1) must set forth the reasons for its issuance;
(2) must be specific in terms;
(3) must describe in reasonable detail, and not by reference to the complaint or other document, the acts restrained; and
(4) is binding only on the parties to the action, their officers, agents, servants, employees, and attorneys, and on those persons in active concert or participation with them who receive actual notice of the order by personal service or otherwise.
(D) Security.
(1) Before granting a preliminary injunction or temporary restraining order, the court may require the applicant to give security, in the amount the court deems proper, for the payment of costs and damages that may be incurred or suffered by a party who is found to have been wrongfully enjoined or restrained.
(2) Security is not required of the state or of a Michigan county or municipal corporation or its officer or agency acting in an official capacity. As to other parties, if security is not required the order must state the reason.
(3) If the party enjoined deems the security insufficient and has had no prior opportunity to be heard, the party may object to the sufficiency of the surety in the manner provided in MCR 3.604(E). The procedures provided in MCR 3.604(F) apply to the objection.
(4) When a bond is required before the issuance of an injunction or temporary restraining order, the bond must be filed with the clerk before the sealing and delivery of the injunction or restraining order.
(E) Stay of Action. An injunction or temporary restraining order may not be granted in one action to stay proceedings in another action pending in another court if the relief requested could be sought in the other pending action.
(F) Denial of Application. When an application for a preliminary injunction or temporary restraining order is denied, but an order is not signed, an endorsement of the denial must be made on the complaint or affidavit, and the complaint or affidavit filed.
(G) Later Application After Denial of Injunction.
(1) If a circuit judge has denied an application for an injunction or temporary restraining order, in whole or in part, or has granted it conditionally or on terms, later application for the same purpose and in relation to the same matter may not be made to another circuit judge.
(2) If an order is entered on an application in violation of subrule (G)(1), it is void and must be revoked by the judge who entered it, on due proof of the facts. A person making the later application contrary to this rule is subject to punishment for contempt.
(H) Motion for Injunction in Pending Actions. An injunction may also be granted before or in connection with final judgment on a motion filed after an action is commenced.
(I) Application to Special Actions. This rule applies to a special statutory action for an injunction only to the extent that it does not conflict with special procedures prescribed by the statute or the rules governing the special action.

Plain-English Summary

MCR 3.310 is the rule to reach for when a case needs a court order now. It separates two forms of relief: the preliminary injunction, which follows a hearing, and the temporary restraining order, which can issue without notice but expires fast.

Preliminary injunctions

Subrule (A)(1) states the baseline: except as a statute or these rules provide otherwise, no injunction issues before a hearing on a motion for a preliminary injunction or on an order to show cause. Subrule (A)(3) makes that motion follow the rules governing other motions unless the court orders otherwise for good cause. Subrule (A)(4) speaks to the hearing on an order to show cause why a preliminary injunction should not issue: the party seeking injunctive relief carries the burden of establishing that the injunction should be issued, whether or not a temporary restraining order has been issued.

Subrule (A)(2) allows the court to advance the trial on the merits and consolidate it with the hearing. Even without consolidation, evidence received at the hearing that would be admissible at trial becomes part of the trial record and need not be repeated, and any right to trial by jury is preserved. Once an injunction is granted, subrule (A)(5) starts a clock: a prompt pretrial conference, trial within 6 months unless good cause is shown or the parties stipulate to a longer period, and a decision within 56 days after trial is completed.

Temporary restraining orders

Subrule (B)(1) sets three conditions for an order granted without notice: specific facts by affidavit or verified complaint showing immediate and irreparable injury from the delay of notice or from the risk that notice itself precipitates adverse action; a written certification from the applicant's attorney about efforts to give notice and why it should be excused; and a permanent record of any nonwritten support.

Subrule (B)(2) requires the order to carry the date and time of issuance, describe the injury and say why it is irreparable and why notice was excused, and, except in domestic relations actions, set a hearing at the earliest possible time. Subrule (B)(3) caps the order, again except in domestic relations actions, at 14 days from entry, extendable for a like period on good cause or for longer with the consent of the restrained party. Under subrule (B)(5) a motion to dissolve takes precedence over all matters except older matters of the same character, may be heard on 24 hours' notice, and puts the burden of justifying continuation on the applicant.

Form, security, and limits

  • Subrule (C) requires the order to set forth its reasons, be specific in terms, and describe the restrained acts in reasonable detail rather than by reference to the complaint. It binds only the parties, their officers, agents, servants, employees, and attorneys, and those in active concert or participation with them who receive actual notice of the order.
  • Subrule (D) lets the court require security for costs and damages to a party found to have been wrongfully enjoined. The state, and a Michigan county or municipal corporation or its officer or agency acting in an official capacity, are exempt; as to other parties, an order requiring no security must state the reason. Objections to the surety follow MCR 3.604(E) and (F).
  • Subrule (E) bars an injunction or restraining order in one action to stay proceedings in another action pending in another court if the relief requested could be sought in that other action.
  • Subrule (G) closes the door on judge shopping. Once a circuit judge denies an application in whole or in part, or grants it conditionally, a later application for the same purpose in the same matter may not go to another circuit judge. An order entered in violation is void and must be revoked, and the applicant is subject to contempt.

Two shorter provisions round the rule out. Subrule (H) allows an injunction to be granted before or in connection with final judgment on a motion filed after the action is commenced. Subrule (I) limits the reach of everything above: the rule applies to a special statutory action for an injunction only so far as it does not conflict with the special procedures the statute or the rules governing that action prescribe.

Frequently Asked Questions

How long does a Michigan temporary restraining order last?

Except in domestic relations actions, a temporary restraining order granted without notice expires within the time the court sets, not to exceed 14 days after entry, under subrule (B)(3). It may be extended for a like period for good cause, with the reasons stated on the record or in a document filed in the action, or for a longer period if the restrained party consents.

Can a TRO be granted without notice to the other side?

Yes, on the showing subrule (B)(1) requires: specific facts by affidavit or verified complaint showing immediate and irreparable injury from the delay of notice or from the risk that notice itself precipitates adverse action, a written certification by the applicant's attorney about efforts to give notice and why it should be excused, and a permanent record of any nonwritten support.

Who has the burden on a show cause hearing for a preliminary injunction?

The party seeking the injunction. Subrule (A)(4) places the burden of establishing that a preliminary injunction should be issued on the party seeking injunctive relief at the hearing on an order to show cause why a preliminary injunction should not issue, whether or not a temporary restraining order has been issued. On a motion to dissolve an order granted without notice, subrule (B)(5) puts the burden of justifying continuation on the applicant for the restraining order.

Does a bond have to be posted before an injunction issues?

Subrule (D)(1) lets the court require security in the amount it deems proper for costs and damages to a party found to have been wrongfully enjoined or restrained. Security is not required of the state or of a Michigan county or municipal corporation or its officer or agency acting officially; for other parties, an order that does not require security must state the reason. When a bond is required, subrule (D)(4) directs that it be filed with the clerk before the order is sealed and delivered.

How soon must a case be tried after a preliminary injunction is granted?

Subrule (A)(5) requires a prompt pretrial conference and trial on the merits within 6 months after the injunction is granted, unless good cause is shown or the parties stipulate to a longer period. The court issues its decision on the merits within 56 days after the trial is completed.

Can a party take a denied injunction request to a different judge?

No. Under subrule (G)(1), once a circuit judge has denied an application in whole or in part, or granted it conditionally or on terms, a later application for the same purpose and in relation to the same matter may not be made to another circuit judge. An order entered in violation is void and must be revoked, and the person making the application is subject to punishment for contempt.
