On Wednesday, Judge Dale Christensen on the U.S. District Court for the District of Montana "reluctantly" dismissed Lighthiser v. Trump, the latest "kids climate suit," on standing grounds. The only thing surprising about this was that Judge Christensen thought it was necessary to hold an evidentiary hearing, featuring multiple witnesses, before reaching this conclusion. Existing Ninth Circuit precedent--from Juliana v. United States, a prior kids climate case--clearly controlled the outcome.
As with prior kids climate cases, Lighthiser involved youth plaintiffs alleging that the federal government's failure to act more aggressively to control greenhouse gas emissions and mitigate climate change violated the plaintiffs' constitutional rights. In particular, the Lighthiser plaintiffs claimed that the Trump Administration's various energy-related Executive Orders and efforts to undo the Biden Administration's climate policies violate the Due Process Clause of the Constitution and are otherwise unlawful. As Judge Christensen noted, the plaintiffs were "effectively asking that this Court order the United States to return to the environmental policy of the previous administration."
Even had the court found a way around the Ninth Circuit's rejection of standing for similar claims in Juliana, the district court would still have been justified in dismissing the case. The Constitutional claim, like those in other kids climate cases, are audacious (to say the least) and at odds with existing jurisprudence. The Lighthiser plaintiffs were nonetheless able to get multiple prominent academics to serve as expert witnesses in their case.
