From notnunut's previous threads, CheekyChops, CLCC will be Central London (County) Court.
Hi notnutnut- I assume you are hoping to find CCTV evidence to support your appeal (something to do with you leaving the court at a key point).
Do you have a solicitor or are you handling this yourself.
Barmaid is probably the best person on here for this but I think she's taking a break. Peter Pedant or TonyWiltshire may be able to advise too.
From what I recall though, I am not sure the recordings, even if they still exist, will help much. Do you have reason to think they may be crucial?
