METEOR BLADE (TIMOTHY LANGE) – The U.S. Supreme Court plunked a setback into the lap of the Environmental Protection Agency Monday [6-29-15] by trashing the agency’s regulation of emissions of mercury and other air toxins (MATS) from electricity-generating plants. The court overturned a lower-court decision in the case of Michigan v. EPA stating that the agency had acted reasonably when it chose not to consider compliance costs first in its effort to control those emissions. The justices split 5-4, with the four liberals on the side of the EPA and the four conservatives and Justice Anthony Kennedy on the side of industry and the states that had sued.
