Subchapter 3.300 — Extraordinary Writs · Last verified September 5, 2026
Full Text of Rule 3.310
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.
