A lawyer for 16 young people on Tuesday asked a Montana judge for a historic order declaring the state’s pro-fossil fuel policies violate their rights, wrapping up arguments in the first youth-led U.S. climate change lawsuit to make it to trial. Judge Kathy Seeley in Helena took the case under consideration on Tuesday after hearing from 12 of the plaintiffs during the course of the trial who described how the state's policies are exacerbating the climate crisis, impacting their health and threatening their futures. Nate Bellinger, an attorney for the young people, said during his closing statement on Tuesday that Seeley should issue a judgment that the state’s ongoing approval of fossil fuel projects violates a state constitutional guarantee to a “clean and healthful environment.”
