I think this was a Purcell principle case though. The court interfering too late could have been a problem.
There is nothing wrong with the map.
The problem is the process. Which means you need to give the WISC a vehicle to overturn the previous courts ruling that in the absence of a legal map they should go with least change.
They didn't do that with the legislative maps. They ruled they were illegal due to continguity.
So the WISC probably needs some local government challenge as a vehicle to overturn the procedural precedent then have someone challenge the existance of any congressional map on the basis the process was illegal.
Otherwise you have Evers and the State AG having to explain why they are now contradicting all the arguments in favor of the map Evers drew.
This a sequencing issue, and if the Court wasn't going to redraw for 2024 anyway they can take some time to save people from squirming or risking perjury
