I can honestly say I have never heard of such a scenario.
You should be allowed access to what is in your personnel file. This may have to be with someone else in the room, but that should be OK. You will be able to take "notes" of what is in your file, but perhaps not photo copies.
I would again ask, in writing, the specific reason for your termination; this may also help. You may want to cc: someone in the Legal department as well as they may be able to assist.
