@J35
you have 2 difficult claims, APA and separation of powers, and with both the merits and remedy of each claim to decide, it is like 4 claims. you know you will have a dissent on each claim. so you have a lot of opinion writing to do, and responses to the other side once the original draft of each opinion is handed over to the other side. plus you have 16 judges so you may have some concurring opinions. plus you are likely to have some negotiations cum arm twisting
so this will take awhile quite apart from the political aspect you mention. a settlement that would preempt the need for publishing the opinions seems well down the road imo, but some (in the minority) judges in the process may have that as a tactic. I tend to doubt it
