A group called Our Children’s Trust offered Held a way to take on this issue. The group was building a case against Montana, and it wanted young people to be involved. Held joined the case as a plaintiff. Fifteen other kids and teens from across the state also joined in.
In 2020, the group filed their lawsuit. Because Held is the oldest, it was filed in her name.
Held v. State of Montana focused on language in Montana’s constitution. It says that people who live in Montana have “the right to a clean and healthful environment.”
The trial began on June 12, 2023. Several plaintiffs gave testimony in which they talked about how climate change is affecting them. Badge Busse, 15, spoke about the effect of wildfires, explaining that he often has to stay indoors to avoid damage to his lungs from the smoky air.
Doctors and scientists also gave testimony. Doctors said the effects of climate change are extra harmful to young people. Scientists talked about the effects of climate change on Montana—now and in the future.
But the state argued that it can’t be blamed for a warming planet. It’s “a global issue,” a lawyer for Montana said.
