I feel like if instead of deferring to the EPA, the Chevron case was deferring to police departments interpretations of the law when the law was ambiguous, we would be cheering this decision as a return to sanity. I wouldn't want the default assumption of the courts to be that when the law is unclear, whatever the sheriff or the highway patrol decides is illegal this month is, and next month or next election it could be something else entirely. In such cases I would absolutely want the courts to evaluate that ambiguity by treating both sides of the argument equally and weighing the law as it stands. So it seems like it should be the same when it comes to regulatory rule making as well. If the law is unclear, deferring to the enforcers of that law seems no different than deferring to the cops. The court system and the government as a whole is already institutionally biased towards the government, without any need for an explicit policy to prefer the government's side.
