What it's about
The Supreme Court wiped out part of the Ninth Circuit’s ruling, overturned another part, and sent the case back to the lower court (vacated in part, reversed in part, and remanded).
The dispute sits at the intersection of immigration enforcement, executive policy choices, and the rules courts use to review federal agencies.
Question presented
1. Whether DHS's decision to wind down the DACA policy is judicially reviewable. 2. Whether DHS's decision to wind down the DACA policy is lawful.
