 judges from Article 3 of the Constitution no longer have to defer to agencies that are creatures of statute as to what the law means when a statute is ambiguous. Chevron was the idea that, well, if the statute's ambiguous, Congress wanted these agencies to make law. And the court said, no, that's not what it means. And it's been bad, it's been around for 40 years, and it's had a lot of ill effects, and we're ending it now.
