Q So, summarize the majority opinion for us. What did the Supreme Court decide?
A So, what the Supreme Court said was that EPA had acted outside its authority under the Clean Air Act, To use generation shifting, which is shifting from fossil fuel based energy sources to renewable energy sources as sort of the foundation of its, um, regulatory approach. And it said, it used, um, what's known as the major questions doctrine as the basis for that. So basically, uh, what that means is it's this legal theory that agencies While they generally get discretion from courts in how they interpret their authority under laws, in the case where you have, um, a regulation that's really politically or economically significant, Congress needs to speak, uh, clearly to wanting to, um, Sort of delegate that power to agencies. So in this case, EPA didn't have a clear mandate under the Clean Air Act from Congress to use generation shifting specifically to create a regulation. So the ruling is actually, you know, a bit more narrow than it could have been. I think a lot of observers were concerned that, you know, what would happen is the Supreme Court might undermine EPA's power and All together to, you know, regulate emissions from power plants, and, and that didn't seem to be what, what happened today.
