A recent U.S. Supreme Court decision limiting federal regulatory powers to interpret ambiguous laws could undermine President Joe Biden's effort to cut tailpipe emissions from the nation’s vehicle fleet. This ruling has placed Biden's tailpipe emission rules on shakier ground, facing legal challenges brought by Republican-led states. These challenges are now heading to a federal appeals court, according to two environmental law attorneys who spoke to Reuters on July 1, 2024.
