Special Immigration Appeals Commission (Procedure) (Amendment) Rules 2018

I have one brief question, about the role of the special advocates. When we discussed the Justice and Security Act, one of the drawbacks of the special advocate procedure, very good though it was, was the inability to re-interview the client after an initial briefing. Does that proviso still work in these cases? In the case of an immigration appeal, are special advocates still unable to re-interview their client to find out their views on the information that has been put before them?
