Second, as of today, my article on the national injunction is in print: “Multiple Chancellors: Reforming the National Injunction.” I’m grateful to the many readers whose criticism made the piece stronger.
If you want to read more about the national injunction, I recommend several good treatments: this article and this article by Michael Morley, this forthcoming article by Zayn Siddique, and this recently published note by Getzel Berger. The intersection of the national injunction with other practices of the federal courts is considered in this piece by Andrew Bradt and Zachary Clopton (on Multi-District Litigation), and this piece by Kate Huddleston (on venue).
