The Revenge of the Lawyers

Economists ousted lawyers (and law) from their central role in the regulatory process. That’s changing.

The Presidency Under Siege

The current Justices are no friends of presidential power.

As recent scholarship has shown, the Supreme Court has been increasingly aggressive in countering exercises of presidential power. From the environmental perspective, West Virginia v.
