What are the facts?
Grupo Mexicano de Desarrollo, S.A. (GMD), a Mexican holding company, issued unsecured notes to investors, including Alliance Bond Fund and others. After GMD encountered serious financial distress and defaulted, the noteholders sued in the Southern District of New York for breach of contract seeking money damages. Concerned that GMD was insolvent or nearing insolvency and allegedly preferring some creditors over others and transferring assets that would frustrate collection, the noteholders sought a preliminary injunction under Federal Rule of Civil Procedure 65 to restrain GMD from dissipating or transferring its assets pending judgment. The district court granted a preliminary injunction freezing GMD's assets up to the amount claimed, reasoning that equitable powers permitted preservation of the status quo to ensure an eventual damages judgment would not be rendered hollow. The Second Circuit affirmed. The Supreme Court granted certiorari to decide whether a federal court sitting in a diversity action for money damages may issue such a prejudgment asset-freeze injunction when the plaintiffs have no lien, security interest, or other equitable interest in the defendant's property and asserted no independent equitable claim at the time the injunction issued.
What is the legal issue?
May a federal court, in a case seeking solely money damages where the plaintiff has no lien or equitable interest in the defendant's property, issue a preliminary injunction restraining the defendant from transferring assets in order to secure a potential judgment?
What rule applies?
Absent statutory authorization or an asserted equitable interest in specific property, a federal court's equitable powers under Rule 65 do not include issuing a preliminary injunction to freeze a defendant's assets to secure satisfaction of a potential money judgment. The scope of federal equitable jurisdiction is defined by the traditional principles of equity exercised by the English Court of Chancery in 1789; because Mareva-type asset-freeze injunctions were not historically available in actions at law for money damages, such relief is beyond the court's equitable authority in those circumstances. Plaintiffs seeking prejudgment security for legal claims must proceed via state-law prejudgment remedies incorporated by Rule 64 or assert an equitable claim or interest that supports in rem or specific relief.
What did the court hold?
No. The Supreme Court reversed, holding that in an action for money damages, where the plaintiff has no lien or equitable interest in the defendant's assets, a federal court lacks authority to issue a preliminary injunction freezing those assets pending adjudication.
What is the reasoning?
1) Historical limits of equity: The Court grounded federal equity jurisdiction in the traditional remedies available in the English High Court of Chancery in 1789, the benchmark for the Judiciary Act's grant of equitable power. Asset-freeze injunctions to secure a prospective damages award (often called Mareva injunctions) are a modern innovation of English courts and were not available at the founding. Because such relief was not part of traditional equity, it is not encompassed within federal courts' inherent equitable powers. 2) Distinguishing Deckert and De Beers: The Court distinguished Deckert v. Independence Shares Corp., which permitted a preliminary injunction to preserve a specific fund where the plaintiffs sought equitable rescission and restitution—relief directly tied to particular assets. By contrast, the noteholders in Grupo Mexicano sought only legal damages and had no equitable claim to any specific res. The decision also drew on De Beers Consolidated Mines v. United States, which cautioned against using preliminary injunctions to restrain assets unrelated to the merits or the ultimate equitable relief. 3) Rule 65 versus Rule 64: Rule 65 does not itself enlarge substantive equitable authority; it regulates procedure for injunctions that equity otherwise permits. When unsecured creditors desire prejudgment security, the appropriate route is Rule 64, which adopts state-law provisional remedies such as attachment or garnishment, subject to their standards and safeguards. Allowing a free-standing federal asset freeze under Rule 65 would circumvent Rule 64 and displace state choices about creditor priorities and protections. 4) Separation of powers and creditor priorities: The majority emphasized that creating a broad federal remedy enabling unsecured creditors to leapfrog others by freezing assets would alter the delicate balance of debtor-creditor law and bankruptcy priorities—subjects traditionally left to legislatures. Any such reallocation of rights and remedies, the Court reasoned, should come from Congress, not judicial expansion of equitable powers. 5) Scope and limits: The Court acknowledged that different results may obtain when a plaintiff asserts an equitable interest in specific property (e.g., a constructive trust, equitable lien, or rescission claim tied to an identifiable fund) or when Congress has expressly authorized asset freezes (as in certain securities, RICO, or FTC matters). But where, as here, the claim is purely legal and unsecured, a preliminary asset restraint is impermissible. 6) Dissent's view: The dissent, led by Justice Ginsburg, argued for a more flexible, evolving equity responsive to modern commercial realities, emphasizing that preserving assets to prevent judgment frustration is consistent with equitable principles and that federal courts historically adapted remedies. The majority, however, rejected this elasticity in favor of the historically anchored limit.
Why is this case significant?
Grupo Mexicano is a touchstone for the modern law of equitable remedies and civil procedure. It sharpens the legal/equitable divide, confining Rule 65 injunctions to traditional equitable contexts and steering unsecured creditors toward Rule 64 state-law prejudgment remedies. After Grupo, courts routinely deny requests to freeze assets in pure damages suits unless the plaintiff shows a lien, security interest, or an equitable claim to specific property, or invokes a statute that expressly authorizes an asset freeze. The decision also has broader implications for separation of powers and federalism: it prevents federal courts from creating new prejudgment creditor remedies that could upend state law and bankruptcy priorities, leaving such policy choices to legislatures.
What is a Mareva injunction, and how did it figure in Grupo Mexicano?
A Mareva injunction is a British-origin asset-freeze order restraining a defendant from dissipating assets before judgment to ensure collectability. In Grupo Mexicano, the plaintiffs sought an analogous asset freeze under Rule 65. The Supreme Court held such relief was not within traditional federal equity in a suit for money damages where plaintiffs had no equitable interest, noting that Mareva injunctions are a modern innovation not available in 1789.
Does Grupo Mexicano bar all preliminary asset freezes in federal court?
No. It bars asset freezes in cases seeking only legal damages where the plaintiff lacks a lien or equitable interest. Asset restraints may still be available when (1) the plaintiff asserts equitable claims tied to specific property (e.g., constructive trust, equitable lien, rescission with restitution of an identifiable fund), or (2) a statute authorizes freezes (e.g., in some SEC, RICO, or FTC enforcement actions).
How do Rule 64 and Rule 65 interact after Grupo Mexicano?
Rule 65 governs injunction procedure but does not expand inherent equitable power. If a plaintiff wants prejudgment security for a legal claim, Rule 64 points them to state-law provisional remedies—attachment, garnishment, replevin—subject to state standards and due process protections. Grupo Mexicano prevents using Rule 65 to create a federal common-law substitute for those state remedies.
What practical steps can unsecured creditors take post-Grupo to protect against dissipation?
They can: (1) pursue Rule 64 prejudgment attachment or similar state remedies; (2) plead and, where warranted, develop equitable claims asserting a specific interest in identified property (e.g., constructive trust based on tracing); (3) seek statutory asset restraints where available; and (4) negotiate for security interests ex ante to avoid relying on post-breach remedies.
How did the Court distinguish Deckert v. Independence Shares from this case?
Deckert allowed a preliminary injunction because the plaintiffs sought equitable rescission and restitution of a specific fund, creating a direct nexus between the assets restrained and the ultimate equitable relief. In Grupo Mexicano, the plaintiffs sought only money damages and had no claim to specific assets; thus, there was no equitable basis to restrain property in advance of judgment.
What policy concerns motivated the majority's limitation on equitable power?
The majority stressed that a broad federal asset-freeze power would reorder creditor priorities, give unsecured creditors undue leverage, and interfere with comprehensive legislative schemes like bankruptcy. It viewed such reallocation of debtor-creditor rights as a legislative—not judicial—function, and anchored equitable powers to historically recognized remedies to avoid separation-of-powers problems.
