Judgment Day for Climate Change Litigation: The U.S. Supreme Court Reverses in AEP v. Connecticut

June 22, 2011

The U.S. Supreme Court issued its decision in American Electric Power v. Connecticut. The Supreme Court unanimously reversed the 2nd Circuit on the issue of displacement, but affirmed, equally divided, on the issue of standing. By deciding this important case on seemingly narrow grounds, the Supreme Court’s decision raised as many questions as it answered, and apparently left the door open for future climate change lawsuits. Regardless, the decision will have profound implications for environmental law generally, as well as for the future of climate change policy in the United States.
