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.
