The fact that nobody was harmed by this regulation -- and there was no urgency -- and yet the Court still took the case is indeed a huge problem that underlines my concerns with this case. Why did the Court step into this case and override both Congress and the executive branch when the regulation itself wasn't harming the plaintiffs? The emergency here is that the EPA now has no idea what its authority will be on any regulatory actions regarding CO2. (And when Congress finally legislates, it won't know what its authority is either.)
