From the 9th Circuit case, Chin did not make a request to the District Court that would result in an injunction or order - he asked for "clarification of SCOTUS order." The District Court, by refusing to render any ruling on that question, did not create an appealable case.
Chin can go back and argue that the SCOTUS order covers his grandparent or granchild US plaintiff, and ask for an injunction against the government. The District Court would have to interpret (not clarify) the SCOTUS order to decide the case.
No matter what the District Court does, that case would be ripe for appeal.
This filing includes the decision from the District Court. The relief requested was essentially a rewriting of the SCOTUS Order.
Not that the decision of the 9th Circuit actually turns on that style, only that is the reason they give for not weighing in.
So are you saying Chin gave his best legal shot, or do you think he’ll come back with something stronger?
