The Supreme Court dealt the EPA a substantial setback in their Monday, June 29 ruling that struck down the Mercury and Air Toxics Standard (MATS).

 

The 5-4 decision ruled that the EPA misinterpreted the Clean Air Act in that they did not consider the costs of the emissions reductions mandated by the rule. This decision overturned an April 2014 District Court ruling that found the EPA had acted within its legal mandate. SCOTUS remanded the the regulation back to the D.C. Circuit Court, which must now reconsider the case.
