Highlighting that "this will forever be in the court record, despite any continued rhetoric of denial coming from people in power in the state," Grace, another plaintiff, said, "I am thrilled that the Montana Supreme Court has sided with Montana citizens to protect the people and the places we love."
Another plaintiff, Olivia, welcomed the ruling as "a monumental win" and "a call to action for all Montanans."
Plaintiff Georgi similarly asserted that "this is a time for Montana to embrace the future—clean energy offers economic benefits and new jobs," and added that "we look forward to working with the state to implement this transition and ensure that Montana leads the way in tackling the climate crisis."
Plaintiff Kian pointed to other ongoing cases across the globe, declaring that "this ruling is not just a win for Montana—it's a signal to the world that youth-led climate action is powerful and effective."
"We hope this decision inspires others across the country and beyond to stand up for their rights to a livable climate," Kian continued. Just as the youth plaintiffs in
Navahine v. Hawaii Department of Transportation secured historic climate justice through a settlement this past June, the eyes of the world are now on us, seeing how youth-driven legal action can create real change."
In Montana, the state government appealed District Court Judge Kathy Seeley's historic ruling in favor of the 16 young plaintiffs to the state's highest court, which
heard arguments in July. Wednesday's 6-1 decision—only Justice Jim Rice dissented—is the first of its kind for a state supreme court.
The majority's 70-page opinion discusses the drafters of the
Montana Constitution, which says in part that "the state and each person shall maintain and improve a clean and healthful environment in Montana for present and future generations," and "the Legislature shall provide for the administration and enforcement of this duty."
Chief Justice Mike McGrath wrote that the court's majority rejects "the argument that the delegates—intending the strongest, all-encompassing environmental protections in the nation, both anticipatory and preventative, for present and future generations—would grant the state a free pass to pollute the Montana environment just because the rest of the world insisted on doing so."
"The district court's conclusion of law is affirmed: Montana's right to a clean and healthful environment and environmental life support system includes a stable climate system, which is clearly within the object and true principles of the framers' inclusion of the right to a clean and healthful environment," the chief justice added.
Attorneys for the plaintiffs joined the young Montanans in applauding the opinion. Nate Bellinger of Our Children's Trust said that "this is a monumental moment for Montana, our youth, and the future of our planet."
"Today, the Montana Supreme Court has affirmed the constitutional rights of youth to a safe and livable climate, confirming that the future of our children cannot be sacrificed for fossil fuel interests," he added. "This is a victory for young people and for generations to come. The court said loud and clear: Montana's Constitution does not grant the state a free pass to ignore climate change because others fail to act—this landmark decision underscores the state's affirmative duty to lead by example."
Melissa Hornbein, senior attorney with the Western Environmental Law Center, noted that "the Montana Supreme Court's decision compels the state to carefully assess the greenhouse gas emissions and climate impacts of all future fossil fuel permits."
"Specifically, Montana's regulatory agencies must now evaluate the potential harm to the environment and the health and safety of the state's children from any new fossil fuel projects, and determine whether the project can be justified in light of the ongoing unconstitutional degradation of Montana's environment, natural resources, and climate," she explained. "This ruling clarifies that the constitution sets a clear directive for Montana to reduce its greenhouse gas emissions, which are among the highest in the nation on a per capita basis, and to transition to a clean, renewable energy future."
Whether the state government will comply with the decision remains to be seen. In a statement to The Hill, a spokesperson for Republican Montana Attorney General Austin Knudsen's office called the ruling "disappointing, but not surprising" and claimed that the court majority "yet again ruled in favor of their ideologically aligned allies and ignored the fact that Montana has no power to impact the climate."
Separately, Knudsen on Tuesday filed his 59th lawsuit against the Biden administration, challenging its plan to halt federal coal production in the Powder River Basin, which the attorney general said would "effectively kill Montana's coal industry."
