I think it's an interesting question and a somewhat tricky one.
For the most part what you see in practice is that tribunals, and I believe courts as well, have jurisdiction over the members who are there. Once a person has left, it would be very unusual for that review in council, or whatever it's called, to then still have jurisdiction over the person who has left. If it were to be done, it would have to be done through very clear legislative enactment. I have not seen it done very much in the work that I've seen in the tribunals I've looked at.
