Intergenerational Equity Litigation
Intergenerational equity litigation uses courts to represent the interests of future (unborn) generations in present-day decisions — most prominently through youth-led climate lawsuits. Where rights-of-nature grants standing to non-human entities, this strategy grants a voice to not-yet-human people: the class of “people who are not people” that existing decision-making systematically ignores.
The core problem
Future generations are the largest constituency affected by long-horizon policy (climate, debt, biodiversity loss) and the only one with zero representation: no votes, no property, no standing. Litigation is one attempt to manufacture representation through guardians — paralleling Stone’s guardianship argument for natural objects (see should-trees-have-standing).
Juliana v. United States (2015–2025)
The flagship case, brought by 21 young plaintiffs organized by the nonprofit Our Children’s Trust, plus an environmental organization and “a representative of future generations,” against the US government.1
Claims. That by continuing to “permit, authorize, and subsidize” fossil fuels despite long knowing the risks, the government violated the plaintiffs’ constitutional rights, including:2
- a substantive due-process right under the Fifth Amendment to a “climate system capable of sustaining human life”;
- Fifth Amendment equal protection and Ninth Amendment rights;
- the public trust doctrine (government holds essential natural resources in trust for present and future generations).
Relief sought. Declaratory relief plus an injunction ordering the government to develop a plan to “phase out fossil fuel emissions and draw down excess atmospheric CO₂.”
Procedural history. The district court (Judge Ann Aiken, D. Or.) denied motions to dismiss, finding standing and recognizing the claimed right. In January 2020, a Ninth Circuit panel reversed and ordered dismissal for lack of Article III standing: while the record “conclusively established” the government’s role and the catastrophic stakes, the court held the requested relief — supervising a decades-long national decarbonization plan — was beyond judicial power and “must be presented to the political branches.” Judge Staton dissented: “the government bluntly insists that it has the absolute and unreviewable power to destroy the Nation.”3
After plaintiffs amended their complaint and the district court again allowed the case (December 2023), the Ninth Circuit in May 2024 granted the government’s seventh mandamus petition and ordered dismissal “without leave to amend.” The Supreme Court denied certiorari on 24 March 2025, ending the case after nearly a decade. Three successive administrations (Obama, Trump, Biden) had all opposed it on procedural grounds.4[raw/articles/legal-planet-juliana-ninth-circuit-2024.md]
Aftermath. Fifteen Juliana plaintiffs took their claims to the Inter-American Commission on Human Rights; Our Children’s Trust pivoted to state courts, where standing barriers are lower and state constitutions sometimes guarantee a right to a clean and healthful environment — most notably Held v. State of Montana, where youth plaintiffs won at trial in 2023 (upheld by the Montana Supreme Court in 2024).5[raw/articles/legal-planet-juliana-ninth-circuit-2024.md]
Standing as the bottleneck
Juliana’s failure mirrors the problem Stone diagnosed in 1972: US Article III standing requires a discrete, particularized, judicially redressable injury — a doctrine built for present, identifiable plaintiffs. The Ninth Circuit explicitly worried that an injury like “dissolution of the Republic would be felt by all citizens equally” and thus fail particularization. Rights-of-nature statutes solve the same problem from the legislative side (statutorily created persons with statutorily appointed guardians); US constitutional doctrine has so far refused to solve it from the judicial side.
Assessment
- Incremental, not blunt. Compared to declaring a park a person, future-generations litigation works within existing rights frameworks (due process, public trust) — but that also makes it hostage to standing doctrine and judicial appetite for structural injunctions.
- Expressive success, remedial failure. Juliana never reached trial, yet it helped spark a global youth climate-litigation movement and generated an unusually candid judicial record of government knowledge of climate risk.
- Design space. Between personhood statutes (NZ), constitutional rights of nature (Ecuador), and public-trust litigation (US), no jurisdiction has yet settled the representation problem — mistakes are part of the search process.
