The Second Circuit has overruled a 1973 precedent that barred organizations from bringing § 1983 lawsuits on behalf of their members. This ruling makes it easier for organizations to sue on behalf of their members.
The case is Defending Education v. Croton-Harmon Union Free School District, issued on September 15. Defending Education challenged student-speech policies adopted by the Croton-Harmon School District in Westchester County. The organization represented three parents whose children attend Croton-Harmon schools. The parents alleged that the district's policies concerning discrimination, harassment, bullying, gender identity, and student speech violated the First Amendment and chilled their children's speech. After the plaintiff organization lost this appeal last year, on a petition for reconsideration, the Court of Appeals (Calabresi, Parker and Nardini), holds that organizations may assert associational standing under the three-part test from Hunt v. Washington State Apple Advertising Commission, 432 U.S. 333 (1977).
What is standing? That legal principle gives you the right to bring a lawsuit. Most litigants have standing: something bad happened to me, and I am bringing a lawsuit. Some organizations can also sue on behalf of their members. That's associational standing, and it is much more complicated.
In Aguayo v. Richardson, 473 F.2d 1090 (2d Cir. 1973), the Second Circuit more than 50 years ago held that organizations could not sue under § 1983 to vindicate the rights of their members. The trial court in this case therefore dismissed the case for lack of standing. In April 2025, the Second Circuit initially affirmed that dismissal because Aguayo was controlling Circuit precedent.
Defending Education then sought reconsideration, asking the Second Circuit to overrule Aguayo. The Court granted the motion, rendering the first appellate ruling in this case a nullity. The Court noted that when Aguayo was decided, the Second Circuit was the first federal appellate court to hold that membership organizations could not bring § 1983 claims on behalf of their members. More than fifty years later, every other federal circuit that had addressed the question had reached the opposite conclusion. The Supreme Court, meanwhile, had repeatedly recognized associational standing, including in cases involving § 1983 claims.
The Supreme Court's decisions in Warth v. Seldin, 422 U.S. 490 (1975), and Hunt are implicated here. Under Hunt, an organization can sue on behalf of its members when three requirements are met: (1) the members would have standing to sue individually; (2) the interests at stake are germane to the organization's purpose; and (3) neither the claim nor the requested relief requires individual members to participate in the lawsuit.
The Second Circuit holds that Aguayo cannot be reconciled with this Supreme Court precedent. It also points to the Supreme Court's recent affirmative action decision in Students for Fair Admissions v. Harvard, 600 U.S. 181 (2023), which applied the Hunt framework to an association asserting constitutional claims under § 1983.
The Court Appeals thus overrules Aguayo's associational-standing rule, as well as later Second Circuit decisions that relied on that rule. What it means is that organizations are no longer categorically barred from bringing § 1983 cases on behalf of their members in the Second Circuit. The case returns to the trial court to determine whether the organization satisfies Hunt's requirements. The Second Circuit expressly to decide whether the organization would ultimately satisfy the requirements for a preliminary injunction.
