This was in the context of a settlement instead of a court verdict. The state cannot really settle the case with Disney though. The legislature could pass a new law making the current court case irrelevant. That's not really the two parties agreeing to a settlement though. It's certainly not the two opposing legal teams agreeing to a compromise. If we include Disney (maybe with help from the state lawyers) lobbying the state legislature to pass that new law and what it looks like, maybe that's a settlement path. But, it's nothing like any other settlement negations in any normal court case. The state lawyers don't really have any negotiating leverage to bring about a settlement instead of complete the outcome in court.
If Disney wins in federal court, nothing else really matters anymore.
If Disney wins in federal court, the board will change back to what it was. Any other change to the composition of the board that is not "revert back because the law that changed it wasn't legal" and "keep the current" would require a new law being passed to change it. Everyone will know what is in the new law, even if they don't know how that content was lobbied for.
They'll all have to "move on", meaning completely reverse their prior positions. Not the "move on" that means Disney just gives up and accepts the new situation.
