In the 6-3 decision [PDF], the court ruled that the Clean Power Plan established under the Barack Obama administration went beyond the EPA's regulatory mandate. Specifically, the EPA had exceeded congressional authority by pushing utilities to make system-wide moves away from coal power generation and toward cleaner forms of electricity production, such as wind and solar energy.What do you think the court should have done in light of what you know from the materials in the Environmental Law materials? Should these issues be left to states or should we have national standards and rules?
