It was the spark that caused the fire: In 1999, 19 organizations, led by the International Center for Technology Assessment (ICTA), petitioned EPA to regulate greenhouse gases from mobile sources under Section 202 of the Clean Air Act. The so-called ICTA petition was denied in 2003 by the Bush EPA (via the Fabricant memo), and the inevitable litigation parade ensued. Several states and environmental groups joined ICTA, and Massachusetts became the lead plaintiff. The case went to the DC Circuit, and in a 2 to 1 decision, the court in Massachusetts v. EPA upheld EPA's decision. A writ of certiorari was filed with the Supreme Court, and the court agreed to hear the case. In a 5 to 4 decision, the court sided with Massachusetts, and the rest was history.
