This has gone back and forth. I don't know what you're asking here. I asked for the complete text of the stip and as far as I can tell you haven't done that. You keep adding new twists. A forum like this can only do so much without looking at all the papers in the case. (and of course, we're not lawyers as you know).
You asked for the reason why they might be able to put the case back on the calendar, but I don't have all the information, so I can't tell you.
If you haven't put in an answer, then perhaps you should (if it's not too late). It looks like they won't have to start over. Apparently you have done something (or not done something) that gives them reason to bring the case back on.
