It should mean the last day of the case where the judge decides what to do. In an adult criminal case, this is usually the sentencing hearing after a plea or a verdict, and in a juvenile case it is the same thing and is actually called the disposition hearing (we don't punish juveniles, you know, we "rehabilitate" them, and we don't "convict" them of crimes, we "adjudicate" them, at least that's the fiction that is used in juvenile proceedings).
