On September 15, 2026, the Second Circuit did something it had refused to do for more than fifty years: it let a membership organization sue on behalf of its members under 42 U.S.C. § 1983 without naming a single one of them. The ruling came on reconsideration in Defending Education v. Croton-Harmon Union Free School District, No. 24-1900 — a First Amendment challenge to a Westchester County school district’s anti-bullying and gender policies — but the holding reaches far beyond one school board. It removes the last circuit-wide bar on associational standing for civil-rights plaintiffs in New York, Connecticut, and Vermont, reaching directly into the litigation strategy of every Second Amendment organization operating in those three states.
Fifty Years as the Outlier
Since 1973, the Second Circuit had read its own decision in Aguayo v. Richardson, 473 F.2d 1090 (2d Cir. 1973), to mean an organization could not itself be the plaintiff in a § 1983 case brought to vindicate its members’ rights. Every other circuit, and the Supreme Court itself, had long since adopted the associational-standing framework of Hunt v. Washington State Apple Advertising Commission, 432 U.S. 333 (1977). The Second Circuit alone held out. Practically, a gun-rights organization with members in Hartford, Burlington, or Buffalo could not sue in its own name over a state firearms law; it had to find an individual member willing to attach a real name to a federal lawsuit and accept whatever consequences that exposure might invite.
What the Panel Actually Held
I want to be precise about the posture, because it matters. This was not an en banc vote of the full Second Circuit. The panel — Judges Guido Calabresi, Barrington D. Parker, and William J. Nardini, who wrote the opinion — ruled on reconsideration after circulating it to every active judge on the court and receiving no objection. That is meaningful institutional buy-in, but it remains the panel’s opinion, not a formal en banc judgment.
What the panel held is unambiguous:
“We overrule the holding in Aguayo v. Richardson, 473 F.2d 1090, 1099 (2d Cir. 1973), that an organization may not ‘sue under [42 U.S.C. § 1983] for the violation of rights of members.’”
The court adopted the Hunt test outright, holding that an organization asserting associational standing must show:
“(a) its members would otherwise have standing to sue in their own right; (b) the interests it seeks to protect are germane to the organization’s purpose; and (c) neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit.”
And it explained why, in language that reads like an apology for fifty years of delay:
“We will no longer cling to Aguayo’s increasingly unpersuasive and anachronistic bar on associational standing in § 1983 cases. Instead, we harmonize our reading of the law to accord with the Supreme Court and a national consensus of our sister circuits.”
One caveat belongs in the record. The panel preserved Aguayo’s other holdings, unrelated to associational standing, and it reversed and remanded — expressing no view on whether Defending Education’s parents actually satisfy the Hunt test, or whether the underlying preliminary injunction should issue. This is a doctrinal win, not a merits win.
Why It Lands Differently After CASA
A ruling like this would have mattered in any era; it matters more now. Trump v. CASA, Inc., 606 U.S. 831 (2025), ended the practice of a single district judge issuing a nationwide injunction protecting people never party to the case. Relief today runs only to the parties before the court, which makes the identity of the plaintiff, not just the merits of the claim, the entire ballgame. An organization that can sue as the representative of its members wins relief for all of them in one judgment. An organization that cannot is reduced to litigating member by member, in a world that no longer lets a single case carry everyone else along for free.
Anonymous Association, Then and Now
The deeper constitutional principle is not new. The right to associate, protected by the First Amendment, has always carried a right to do so without disclosing your name to the government — a tradition running back to the Federalist Papers, published under the pseudonym Publius rather than the names of Hamilton, Madison, or Jay. Defending Education is litigated by pseudonymous “Parents A, B, and C” for exactly that reason: named plaintiffs risk retaliation. Second Amendment organizations have the identical interest. A member of the Second Amendment Foundation, the Firearms Policy Coalition, or Gun Owners of America who does not want a New York or Connecticut agency to know he owns a rifle can now be represented without being unmasked.
Grant v. Higgins, the Connecticut assault-weapons-ban case pending at the Supreme Court out of the Second Circuit, is the clearest illustration of why gun-rights litigants in this circuit needed this rule fixed. I will also note, as my own forward-looking argument rather than anything this opinion holds, that associational standing is the same doctrine letting non-named members of an organization benefit from favorable rulings won elsewhere — and the Second Circuit’s fifty-year holdout had been the one place that benefit could not yet reach.
The Second Circuit Joins the Rest of the Country
Defending Education is a school-policy case on its face; its holding is a civil-procedure ruling on Article III standing. But it removes the one structural obstacle that made the Second Circuit uniquely hostile terrain for organizational plaintiffs, gun-rights groups included. The merits of any Second Amendment case in New York, Connecticut, or Vermont still have to be litigated and won. What changes is who gets to walk through the courthouse door — and after five decades as the lone holdout, the Second Circuit has finally let every membership organization in.
