Last week the Supreme Court struck a momentous blow for the Constitution and individual liberty when it overturned a dreadful decision it made in 1984.
A few days ago in a pair of related rulings the Supreme Court struck down a 1984 decision, Chevron v. Natural Resources Defense Council, which had enormously and dangerously increased the powers of government agencies. What came to be called the “Chevron deference” meant that if there was any ambiguity or question—no matter how flimsy or far-fetched—about what a law actually meant, the courts had to defer to the judgement of the agency in question.
