D.C. Circuit Review – Reviewed: Boo-Hoo, Daniel Epps!

The Supreme Court is in crisis. It is already June yet almost half of the High Court’s cases remain undecided. For the Justices to finish their work by July 1, they will have to decide “29 of 63 argued cases” this month alone. What is happening? And why? Most importantly, can the Court — nay, […]

D.C. Circuit Review – Reviewed: [Under Seal]

For two days this week, there was a mystery in the D.C. Circuit: Why did the Court rule against “James Mattis, in his official capacity as Secretary of Defense” in Doe v. Mattis? As you probably already know, the case is about the government’s authority to transfer a U.S. citizen — also a citizen of […]

D.C. Circuit Review – Reviewed: “Why Congress Matters: The Collective Congress in the Structural Constitution”

Hence, when April comes around, I’ve learned that for […]

D.C. Circuit Review – Reviewed: Hello Again, Browning-Ferris

by Aaron Nielson — Friday, Apr. 13, 2018@Aaron_L_Nielson

Warning: Unless you enjoy reading docket entries, this is not an especially exciting post. A few months ago I authored a post called “Bye-Bye, Browning-Ferris.” There, I addressed the NLRB’s decision to overrule Browning-Ferris, a precedent which had “made it easier for unions to go after franchisees and contractors. Before Browning-Ferris, companies were ‘joint employers’ […]

D.C. Circuit Review – Reviewed: Trivia Day

There are many talented people in this world. Some people can sing; others can dance; others still can pole vault, run regressions, mimic bird calls, entertain large crowds with wit and charm, or even switch hit. Alas, I can do none of those things. Instead, I have only two real skills: I can (1) sleep […]

Drawing Two Lines

by Aaron Nielson — Tuesday, Apr. 3, 2018@Aaron_L_Nielson

Let me begin with a confession: I’m not an expert on the meaning of the Appointments Clause. Of course, because I teach administrative law, I know the basics — I’ve read the leading cases and even some law review articles. Even so, I approach this symposium as a layman, not an expert. Yet even as […]
