Summary:
On 23 April 2026, a court in the US state of Wisconsin ruled in a youth climate case against the Wisconsin Public Service Commission and the Wisconsin State legislature. The case was filed by fifteen young people ranging in age from 8-17. The youth plaintiffs had challenged the constitutionality of statues governing the approval of fossil fuel-fired power plants because those statutes limit the ability of the first respondent, the Public Service Commission of Wisconsin, to consider air quality impacts of when issuing permits for such plants. In doing so, they had invoked their rights, under the Wisconsin state constitution, to liberty and to life, as well as the rights to a stable climate system and to access, enjoy and use navigable waters (both of which they considered inherent within the constitution). They also alleged a violation of Wisconsin’s public trust doctrine.
According to the Plaintiffs, climate change has rendered them unable to enjoy Wisconsin’s natural resources, like its rivers and lakes, as well as prevented them from engaging in recreational activities, like swimming and skiing. Some are deprived of their Indigenous cultural traditions, while others have experienced asthma and contracted Lyme disease.
The judge tasked with resolving this case, Judge Julie Genovese, ruled that “[w]hile the court is sympathetic to the youths and admires their willingness to access the courts in their quest to protect the planet, I conclude that the case must be dismissed because environmental policy is a nonjusticiable political question”. The judge discussed Wisconsin’s political question doctrine, which “dictates that courts will not decide questions that require the court to determine what the best or wisest public policy would be”, and “also embodies a practical component, recognizing that matters of economic and social policy are not reasonably “susceptible to judicial management or resolution.””
The judge concluded that:
“by substituting this court’s judgment for the legislature, the court
would be showing a lack of respect for the legislative and executive branches. Plaintiffs do not like these policy decisions. (…) Because Plaintiffs think it is technologically and economically feasible for Wisconsin to be carbon free by 2050, they conclude that by invalidating the statutes and thus their limitations, the PSC will decide to stop approving fossil fuel-fired plants, and Plaintiffs’ carbon free goal will be achieved. While the court may agree with Plaintiffs’ policy preferences, it would show a blatant lack of respect for our elected officials and the agency defendants to substitute my judgment for theirs, and strike the limitations imposed by the legislature and executed by the PSC. Accordingly, because the court concludes that the legislature’s policy decisions represent a nonjusticiable political question, this case must be dismissed.”
