 Well, and Elizabeth, a lot of this gets back to Congress. If you pass laws that are ambiguous and say, we'll just let the regulatory state take care of it, how much work does it now mean more work that maybe they've got to do on Capitol Hill? Well, yeah, exactly. The point was that, of course, if Congress enacted a law and the agency was acting directly contrary to that clear congressional act, that has always been impermissible.
