John Vecchione sits down with Kara Rollins to explore her recent piece in the Yale Journal on Regulation titled “Necessary” Discretion: A Primer for Non-Lawyers. They delve into what it really means when legislatures grant agencies the authority to act when something is “necessary,” how courts interpret these trigger‐words, and why this matters for administrative power. From the Spending Clause to rule‐making, this conversation breaks down complex doctrine in plain terms and shows how “necessary” might mean more than you think.
