Attorney Julia Olson founded the nonprofit public interest law firm Our Children’s Trust in 2010 in Eugene. Five years later, she filed a lawsuit on behalf of Kelsey Juliana and 20 other youth activists in Oregon and elsewhere. Their contention was simple on its face: youth have a right to a stable climate, just as they have a right to clean water and clean air. It used the public trust doctrine in a novel way at the time. Since the suit was filed in 2015, Juliana v. U.S. has been in and out of district and appeals courts and was cleared to go to trial in 2023. But last year, the 9th Circuit Court of Appeals granted the federal government's motion to dismiss the case. The U.S. Supreme Court recently declined to intervene, but dismissed the case “without prejudice,” enabling the case to potentially be filed at a later time. Olson joins us to talk about what the last decade has shown her and the "Juliana 21" about the most effective ways to challenge climate change policy in the U.S. today.
