Subject: Re: SCOTUS today
The decision does not prohibit agencies from engaging in rule-making. It undoes the presumption of correctness that applies to their interpretation of statutes. Chevron said that where statutes are ambiguous, courts should defer to what the agencies thought those statutes meant, rather than trying to resolve the ambiguity independently. Rule-making wasn't at issue, except to the extent that rules are often the subject of these types of disputes.

Yup, this. All this does is restore the pathway that's normally there when you want to challenge a law, i.e. via the courts.
