A group of 16 young Montanans, aged between 5 and 22, won the nation’s first-of-its-kind climate change trial this week, setting a precedent for more such rulings and cases in court.

District Court Judge Kathy Seeley, overseeing Held v. Montana case, ruled on Monday that the state agencies were violating the youths’ right to a “clean and healthful environment” by allowing fossil fuel projects without considering its effects on climate.

The ruling is significant since Article IX, Section 1 of Montana’s Constitution indicates 

In short,
Montana has to now consider climate change effects before approving any new fossil fuel and energy development projects.

The state plans on appealing the ruling to the Supreme Court.
