I had my appeal today and received everything I submitted originally back at the end of the appeal hearing.
Not all the evidence I put forward at the beginning was included in the case papers but the panel did have a copy of them when we arrived.
Not sure if this is any comfort but it may be the same thing has happened with yourselves and find they have the copies at the meeting. Hope this is the case.
Good luck, and my advise, know your evidence inside and out as they may ask you something you hadn't thought about.
