    Today, WHEN submitted an amicus brief in Suncor Energy v. Boulder County, which will be argued before the U.S. Supreme Court on October 5.

    Our brief challenges the argument that the Constitution gives polluters special immunity from state-law claims involving interstate pollution – an argument that, if accepted, could limit the ability of states, communities, and individuals to seek redress for harm.

    Regardless of where you stand on climate policy, this case raises important questions about federalism, accountability, and who gets to decide whether injured parties have access to remedies.
