@cp8759 Please be advised that the evidence must be provided 5 days before the hearing not 7 as you have stated. 
@Hippocrates but paragraph 7(6) of Schedule 1 to the LLA 1996 says:
(6) Nothing in sub-paragraph (1) or (4) above makes a document admissible as evidence in proceedings under paragraph 6 above unless a copy of it has not less than 7 days before the hearing, been served on the appellant; and nothing in those paragraphs makes a document admissible as evidence of anything other than the matters shown on a record produced by a prescribed device if that person, not less than three days before the hearing or within such further time as the traffic adjudicator may in special circumstances allow, serves a notice on the enforcing authority requiring attendance at the hearing or trial of the person who signed the document.
Has there been an amendment I have missed?
