 I don't think they're going to stop their work. They're going to keep issuing regulations because they have to. The Clean Air Act and other statutes says that they have to address these problems, but they will have to take the time to be more careful because the courts they know are going to be an uphill battle for them. And I think this case, overturning Chevron and the other related cases, are really an invitation to petitioners to litigate more often, to challenge more agency rules, because they know that the agencies no longer enjoy a sort of presumption of regularity.
