An arbitrator can issue an injunction when the arbitration agreement or the institutional rules the parties adopted give the arbitrator that power. Unlike a judge, an arbitrator has no built-in authority to order anyone to do or stop doing anything. That authority has to come from somewhere specific: the contract, the rules incorporated into it, or both. And even a properly issued arbitral injunction doesn’t enforce itself. To put real teeth behind it, the winning party has to take the order to a court for confirmation.
Where the Power Comes From
Start with the arbitration agreement. If the contract says the arbitrator can award “any relief available at law or in equity,” that language typically covers injunctions. Many agreements don’t say it that directly. Instead they incorporate a set of institutional rules by reference, and those rules do the work.
The two most common domestic institutions both authorize injunctive relief in plain terms. AAA Commercial Rule R-38 says an arbitrator “may take whatever interim measures he or she deems necessary, including injunctive relief and measures for the protection or conservation of property.”1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures JAMS Comprehensive Arbitration Rule 24(e) uses nearly identical language, authorizing arbitrators to “grant whatever interim measures are deemed necessary, including injunctive relief.”2JAMS. Comprehensive Arbitration Rules and Procedures When an agreement incorporates either set, the arbitrator has clear authority to issue an injunction with no additional contractual language needed.
Behind all of this sits the Federal Arbitration Act. Section 2 of the FAA declares that written arbitration agreements in contracts involving commerce “shall be valid, irrevocable, and enforceable.”3Office of the Law Revision Counsel. 9 USC 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate The FAA doesn’t specifically mention injunctive relief, but courts have consistently read it to support whatever remedies the parties’ agreement permits.
What Kinds of Injunctions Are Available
Interim Relief During the Arbitration
An interim injunction is issued while the case is still pending, to keep the situation stable until the arbitrator can decide the merits. The typical scenario: a party is about to destroy evidence, liquidate disputed assets, or breach a non-compete, and waiting for the final award would make any eventual remedy meaningless. Under AAA Rule R-38, interim measures can take the form of an interim award, and the arbitrator can require the party seeking relief to post security.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures
Permanent Injunctions in the Final Award
A permanent injunction is part of the final award, issued after the arbitrator has heard the evidence and decided the case. Injunctive relief generally applies only when money damages alone won’t fix the problem.4Legal Information Institute. Injunctive Relief The order can prohibit conduct (say, continued use of a former employer’s trade secrets) or require conduct (say, delivery of goods under a breached contract).5Legal Information Institute. Mandatory Injunction Once confirmed by a court, it carries the same weight as a judge’s order.
Emergency Relief Before the Tribunal Exists
Sometimes protection is needed before the arbitral panel has even been assembled. Both AAA and JAMS address this with emergency arbitrator procedures. Under AAA Rule R-39, a party can request emergency relief, and the AAA appoints a single emergency arbitrator within one business day. That arbitrator then has two business days from appointment to establish a hearing schedule.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures The bar is high: the requesting party has to show that “immediate and irreparable loss or damage” will result without relief. The ICC offers a similar mechanism under Article 29 of its Arbitration Rules, with the emergency measure taking the form of an order the full tribunal can revisit once seated.6International Chamber of Commerce.

What an Arbitrator Cannot Reach
The power is real, but bounded. Arbitration rests on consent, which means an arbitrator can only bind the parties who signed the agreement. A third party who never agreed to arbitrate generally cannot be pulled into the process or subjected to an arbitral injunction. This shows up often in intellectual property disputes where the alleged infringer operates through subsidiaries or affiliates that never signed the contract. Reaching those parties takes a court order.
Agreements can also carve injunctive relief out entirely. Contracts involving trade secrets or IP frequently include language like “any dispute shall be resolved by arbitration, except for actions seeking injunctive relief.” Where such a carve-out applies, the arbitrator has no authority to issue an injunction and the party seeking one has to go to court.
Going to court for interim relief while arbitration is pending is not a waiver. Both AAA Rule R-38 and JAMS Rule 24(e) state explicitly that seeking such relief from a court is not incompatible with the agreement to arbitrate.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures That matters in practice, because there are situations where even an emergency arbitrator cannot act quickly enough.
Turning the Injunction Into Something Enforceable
This is where people often get tripped up. An arbitrator has no contempt power, cannot dispatch a marshal, and cannot impose fines for noncompliance. To make an arbitral injunction operational, a court has to confirm it.
Under 9 U.S.C. § 9, a party can apply to the court specified in the arbitration agreement for an order confirming the award, and the court “must grant such an order” unless the award is vacated, modified, or corrected under sections 10 or 11. Once confirmed, the award becomes a court judgment, enforceable through the usual mechanisms, including contempt for violation. The application must be filed within one year after the award. If the agreement doesn’t specify a court, the application can go to the federal district court for the district where the award was made.7Office of the Law Revision Counsel. 9 USC 9 – Award of Arbitrators; Confirmation; Jurisdiction; Procedure
The court’s review is deliberately narrow. A judge will not re-examine the merits or second-guess the arbitrator’s reading of the law. Under 9 U.S.C. § 10, an award can be vacated only in limited circumstances: fraud in procuring the award, evident partiality by the arbitrator, refusal to hear material evidence or other prejudicial misconduct, or the arbitrator exceeding the powers granted by the agreement.8Office of the Law Revision Counsel. 9 USC 10 – Same; Vacation; Grounds; Rehearing That last ground is the one that matters most for injunctions. If the agreement didn’t authorize injunctive relief, or the arbitrator issued an injunction that went beyond the scope of the dispute, a court can vacate it as beyond the arbitrator’s authority.
Budget time and legal fees for confirmation. The injunction isn’t fully operational until a court signs off.
Going Straight to Court in a True Emergency
Courts and arbitrators don’t operate in sealed lanes. When the tribunal has not been formed and even an emergency arbitrator procedure would be too slow, a party can go directly to a court for a preliminary injunction or temporary restraining order to hold the status quo while arbitration gets underway. Both AAA and JAMS rules permit this without treating it as a waiver of the right to arbitrate.2JAMS. Comprehensive Arbitration Rules and Procedures The court issues the order to keep things in place, then steps back and lets the arbitrator take over the substance. Once the tribunal is seated and able to act, the arbitrator can modify, continue, or dissolve whatever interim relief the court put in place.
