State of Michigan, et al. v. Environmental Protection Agency, et al. (U.S. 14-46 and consolidated cases)
In March 2015, the Emmett Clinic filed an amicus brief in the U.S. Supreme Court on behalf of the Union of Concerned Scientists to defend the Environmental Protection Agency’s regulations limiting emissions of mercury and other hazardous air pollutants from power plants. In its brief, the Clinic argued that Congress, in directing EPA to issue regulations if “appropriate and necessary,” intended that the agency make a scientific decision based on the public health impacts of the industry’s emissions.
