If no vote is called for, we could know, as soon as Wed.
If the vote is called for, it can take up to 14 more days. Should the majority decided against rehearing the case, any judge with a strong feeling can write a dissenting opinion on why the court should have taken the case. That takes time. So it could be weeks, before we know.
If there is to be a rehearing, there is no certain date by which the Court must notice the parties. We will certainly know, before the 180 day stay is withdrawn.
