Associations Matter More Than Ever for Securing Nationwide Relief
The US Supreme Court’s recent decision in CASA v. Trump, 606 U.S. 831 (June 27, 2025) sharply limited the ability of individual plaintiffs to obtain nationwide injunctions. Of course, those seeking nationwide injunctions can try to bring class actions on behalf of a class of plaintiffs across the country. But class actions can be cumbersome, and the process of getting a class certified may result in delay, expense, and uncertainty.
Critically, there is another mechanism for broad-based injunctive relief: A national trade or professional association may bring suit on behalf of its members throughout the United States. Associations are uniquely able to aggregate member concerns about specific governmental or other policies, to demonstrate nation-wide harm, and to obtain nationwide relief.
The Supreme Court Continues to Recognize Associational Standing
The cornerstone of associational standing is the three-part formulation articulated in Hunt v. Washington State Apple Advertising Commission, 432 U.S. 333 (1977): An association may seek injunctive relief on behalf of its members when (1) at least one identified member would otherwise have standing; (2) the interest at stake is germane to the organization’s purpose; and (3) neither the claim nor the relief sought requires individual participation by those members. This was reaffirmed in New York State Club Ass’n, Inc. v. City of New York, 487 U.S. 1, 9 (1988) and in Students for Fair Admissions, Inc. v. President & Fellows of Harvard Coll., 600 U.S. 181 (2023). The Court also has clarified that Hunt’s first two prongs—member injury and germaneness—are rooted in Article III, whereas the third prong is a prudential limit that may be relaxed. United Food & Commercial Workers Union Local 751 v. Brown Group, Inc., 517 U.S. 544 (1996). The Brown Group Court also reaffirmed that at least one member with standing suffices, cementing the doctrine as a practical, workable mechanism for industrywide litigation.
The Court has emphasized the special features, advantageous both to the individuals represented and to the judicial system as a whole, that distinguish union and association suits from conventional class actions. International Union, United Automobile, Aerospace & Agricultural Implement Workers v. Brock, 477 U.S. 274 (1986). Associations, the Court explained in Brock, possess a pre-existing reservoir of expertise and capital and exist precisely so that members may combine resources to vindicate shared interests.
Last year, Justice Thomas questioned whether associational standing should continue to exist. See Food and Drug Administration v. Alliance for Hippocratic Medicine, 602 U.S. 367, 398 (2024). Yet the Court has not taken action to address that question or to otherwise signal a change in doctrine.
The Case for Associational Litigation
Economies of Scale and Risk Pooling
Associational litigation allows multiple firms or individuals to share the costs and risks of challenging governmental action. For members, this means robust advocacy at a fraction of the cost required to litigate alone.Uniform, Nationwide Relief
Many regulatory threats apply equally across our country. A nationwide injunction ensures that no member is left behind and that competitive parity is preserved. In contrast, firm or individual-specific relief can create patchwork compliance burdens and competitive distortions.Procedural Advantages
Most associational suits seek forward-looking, injunctive relief that does not require the individualized damages calculus that so often bogs down class actions. This streamlined posture accelerates judicial review and minimizes discovery burdens. Moreover, associations can present consolidated, industry-wide data, often drawn from their own research departments.Enhanced Credibility With Courts and Policymakers
Judges sometimes acknowledge that trade and professional associations convey the considered judgment of an entire sector. This credibility can translate into deference on technical questions, particularly where agencies may have failed to provide adequate notice and comment rule-making.Amplified Member Value Proposition
For associations, impactful litigation is a tangible demonstration of member benefit. Each injunction not only delivers immediate value to members but also showcases the association’s strategic relevance, strengthening retention and recruitment. And even if the plaintiff association does not prevail, the mere bringing of a lawsuit demonstrates that the association is trying to promote the interests of its members. As the General Counsel of one association once said, “We win this case on the day we file it because we show our members that we are advocating for their interests”.
Conclusion
Litigation brought by associations seeking nationwide injunctions against government can deliver strategic, member-focused value on a nationwide basis, and should be strongly considered by associations particularly in light of the now-changed landscape for nationwide relief. ArentFox Schiff has substantial experience bringing this type of litigation on behalf of associations.
