A. AVAILABILITY GENERALLY
(1) Circumstances. Subject to the requirements of Rule 82A.(1), a temporary restraining order or preliminary injunction may be allowed under this rule:
(a) When it appears that a party is entitled to relief demanded in a pleading, and such relief, or any part thereof, consists of restraining the commission or continuance of some act, the commission or continuance of which during the litigation would produce injury to the party seeking the relief; or
(b) When it appears that the party against whom a judgment is sought is doing or threatens, or is about to do, or is procuring or suffering to be done, some act in violation of the rights of a party seeking judgment concerning the subject matter of the action, and tending to render the judgment ineffectual. This paragraph shall not apply when the provisions of Rule 83E, F.(4) and H.(2) are applicable, whether or not provisional relief is ordered under those provisions.
(2) Time. A temporary restraining order or preliminary injunction under this rule may be allowed by the court, or judge thereof, at any time after commencement of the action and before judgment.
B. TEMPORARY RESTRAINING ORDER
(1) Notice. A temporary restraining order may be granted without written or oral notice to the adverse party or to such party's attorney only if:
(a) It clearly appears from specific facts shown by an affidavit, a declaration or a verified complaint that immediate and irreparable injury, loss, or damage will result to the applicant before the adverse party or the adverse party's attorney can be heard in opposition, and
(b) The applicant or applicant's attorney submits an affidavit or a declaration setting forth the efforts, if any, which have been made to notify defendant or defendant's attorney of the application, including attempts to provide notice by telephone, and the reasons supporting the claim that notice should not be required. The affidavit or declaration required in this paragraph shall not be required for orders granted by authority of ORS 107.095 (1)(c), (d), (e), (f) or (g).
(2) Contents of order; duration. Every temporary restraining order granted without notice shall be endorsed with the date and hour of issuance, shall be filed forthwith, shall define the injury and state why it is irreparable, and shall state why the order was granted without notice.
(a) Every temporary restraining order shall expire by its terms within such time after entry, not to exceed 10 days, as the court fixes, 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 shall be entered of record.
(b) The 10-day limit of paragraph (a) of this subsection does not apply to orders granted by authority of ORS 107.095 (1)(c), (d), (e), (f) or (g).
(3) Hearing on preliminary injunction. In case a temporary restraining order is granted without notice, the motion for a preliminary injunction shall be set down for hearing at the earliest possible time and takes precedence over all matters except older matters of the same character. When the motion comes on for hearing the party who obtained the temporary restraining order shall proceed with the application for a preliminary injunction and, if such party does not do so, the court shall dissolve the temporary restraining order.
(4) Adverse party's motion to dissolve or modify. On two days' notice (or on shorter notice if the court so orders) to the party who obtained the temporary restraining order without notice, the adverse party may appear and move for dissolution or modification of such restraining order. In that event the court shall proceed to hear and determine such motion as expeditiously as the ends of justice require.
(5) Temporary restraining orders not extended by implication. If the adverse party actually appears at the time of the granting of the restraining order, but notice to the adverse party is not in accord with subsection C.(1), the restraining order is not thereby converted into a preliminary injunction. If a party moves to dissolve or modify the temporary restraining order as permitted by subsection (4) of this section, and such motion is denied, the temporary restraining order is not thereby converted into a preliminary injunction.
C. PRELIMINARY INJUNCTION
(1) Notice. No preliminary injunction shall be issued without notice to the adverse party at least five days before the time specified for the hearing, unless a different period is fixed by order of the court.
(2) Consolidation of hearing with trial on merits. Before or after the commencement of the hearing of an application for preliminary injunction, the parties may stipulate that the trial of the action on the merits shall be advanced and consolidated with the hearing of the application. The parties may also stipulate that any evidence received upon an application for a preliminary injunction, which would be admissible upon the trial on the merits, becomes part of the record on trial and need not be repeated upon the trial.
D. FORM AND SCOPE OF INJUNCTION OR RESTRAINING ORDER Every order granting a preliminary injunction and every restraining order shall set forth the reasons for its issuance, shall be specific in terms, shall describe in reasonable detail (and not by reference to the complaint or other document) the act or acts sought to be restrained, and is binding only upon the parties to the action, their officers, agents, servants, employees, and attorneys, and upon those persons in active concert or participation with any of them who receive actual notice of the order by personal service or otherwise.
E. SCOPE OF RULE E.(1) This rule does not apply to a temporary restraining order issued by authority of ORS 107.700 to 107.735 or 124.005 to 124.040 or 163.760 to 163.777. E.(2) This rule does not apply to temporary restraining orders or preliminary injunctions granted pursuant to ORCP 83 except for the application of section D. of this rule. E.(3) These rules do not modify any statute or rule of this state relating to temporary restraining orders or preliminary injunctions in actions affecting employer and employee.
F. WRIT ABOLISHED The writ of ne exeat is abolished.

Plain-English Summary

Rule 79 covers the two tools a court can use to stop someone’s conduct before a case ends: a temporary restraining order, meant to hold things in place for a short stretch, and a preliminary injunction, meant to last through trial. Either is available once a case has been filed and before judgment, in two situations — when the relief a party is asking for in their pleading includes stopping some ongoing or threatened act that would hurt them if it continued during the litigation, or when the opposing party is doing or about to do something that would undercut the judgment the party is trying to win.

A temporary restraining order can issue without notifying the other side, but only on a strong showing: specific facts in an affidavit, declaration, or verified complaint proving immediate, irreparable harm before the other side could be heard, plus an account of whatever efforts were made to reach the other side first, including by phone. An order granted this way has to spell out the injury, explain why notice was skipped, and expire within 10 days unless extended for a like period on good cause, or longer if the restrained party agrees. If a restraining order issues without notice, the court sets the preliminary injunction hearing for the earliest possible date and gives it priority over most other matters; if the party who got the order doesn’t pursue the injunction, the court dissolves it. The restrained party can also move to dissolve or modify the order on two days’ notice, and having the other side show up when the order is granted, or losing a motion to dissolve it, doesn’t turn a temporary order into a preliminary injunction on its own.

A preliminary injunction, by contrast, requires at least five days’ notice to the other side unless the court sets a different period, and the parties can agree to fold the injunction hearing into the trial itself. Every injunction or restraining order — temporary or preliminary — has to explain why it issued, describe the restrained conduct in specific detail rather than by pointing to the complaint, and it binds only the parties, their agents and attorneys, and others acting with them who get actual notice. The rule steps aside for restraining orders issued under Oregon’s family abuse, elder and vulnerable person abuse, and stalking statutes, for provisional process under Rule 83, and for other statutes or rules governing restraining orders and injunctions in actions between employers and employees, and it abolishes the old writ of ne exeat.

Frequently Asked Questions

What’s the difference between a temporary restraining order and a preliminary injunction under Rule 79?

A temporary restraining order is meant to hold things in place for a short time, and can be granted without notifying the other side if there’s a strong showing of immediate, irreparable harm. A preliminary injunction is meant to last through trial, and generally can’t be granted without giving the other side at least five days’ notice and a chance to be heard.

How long does a temporary restraining order last in Oregon?

A temporary restraining order expires within whatever time the court fixes, up to 10 days, unless the court extends it for a like period on a showing of good cause, or the restrained party agrees to a longer extension — and the court has to put its reasons for any extension on the record. This 10-day ceiling doesn’t apply to certain restraining orders issued under Oregon’s family-law statutes, which run on their own separate timeline.

Can a court issue a TRO without telling the other side first?

Yes, but only on a strong showing. The party asking for it must submit an affidavit, declaration, or verified complaint laying out specific facts showing that immediate and irreparable injury will happen before the other side could be heard, along with a separate affidavit or declaration describing whatever efforts were made to notify the other side — including by telephone — and why notice should be skipped altogether.

How much advance notice does the other side get before a preliminary injunction hearing?

At least five days, unless the court sets a different period. This is separate from — and longer than — the showing needed to get a temporary restraining order without any notice at all.

Can the restrained party ask the court to dissolve or modify a TRO?

Yes. On two days’ notice to the party who obtained the order — or less, if the court allows it — the restrained party can move to dissolve or modify it, and the court has to hear and decide that motion as quickly as the circumstances allow. Showing up at the hearing or losing that motion doesn’t turn the temporary order into a preliminary injunction on its own.

Does Rule 79 apply to restraining orders in domestic abuse or stalking cases?

No. Rule 79 steps aside for restraining orders issued under Oregon’s separate family abuse prevention, elder and vulnerable person abuse, and stalking statutes, and for provisional process under Rule 83 (except for the rule’s requirements on the form and scope of an order). It also doesn’t override any other statute or rule governing restraining orders and injunctions in disputes between employers and employees.
