You must not have paid a lot of attention in class?
I would think if you reached a private agreement which is then incorporated into an order that you are stuck with the order --and that either side must meet the criteria to open or seek modification to the order.
But the precise language you quote seems ultra sloppy and invites taking view that it is now time to change...and if the deal was to waive CS until you completed school and you now complete school it might be a plausible reason to open it.
BTW, despite the fact that places are laying off teachers, at least in my area a Dr of Law degree is an earned doctorate (w/o admission to bar) and puts one at top of public school salary structure especially in schools trying to paint picture of how well educated their staff is. You might need say 4 mickey mouse courses for a state certificate then again in my area they seem to issue emergency certificates to warm toadstools
