In this instance, you would not be starting from scratch. The court has already issued an order, with a time limit. The law has to meet the court ordered criteria, and the court gets to decide if they have met it.
It is not as if someone has to bring a new lawsuit. It is more like the Kansas case, where the court ordered a school district to do certain things, and then judged whether they accomplished those things or not.
That is how it appears to me, with the limited information about the case that I have read.
OK, fair enough. Would be interesting to see what the court ordered and what the pols come up w/. Even so look at Heller vs DC. Although not identical its similar in nature. I think it was some time before DC kinda sorta did something toward what the court ordered. It seems to me the pols could keep this tied up in court for some time. That is, the pols have little respect for court orders unless it fits their agenda.
