I think all that has been said so far covers most of the points. However, I must correct one or two points so as not to falsely raise ali_alic�s hopes.
Barmaid suggests that the prosecution cannot continue if the trial date is more than six months after the event. This is not correct. Summary offences (that is those that can only be heard by magistrates) have to have their proceedings started, but not necessarily concluded, within six months of the alleged offence. Many cases (especially those where a trial is necessary) take considerably more than six months to come to a conclusion and are not thrown out when six months have elapsed. Proceedings clearly have begun in this case as, from what has been said, there has already been at least one hearing.
One other more minor point is that magistrates � even sensible ones - do not have the power (as has been intimated by willowman) to �throw the matter out and tell the police not to waste the court�s time�. If the prosecution has been properly brought, the prosecution agency wants to continue their prosecution, and the defendant pleads not guilty, the matter must go to a full trial. The earliest opportunity the magistrates then have to dismiss the matter is after hearing the prosecution evidence. At this stage they may be asked by the defence to rule that there is �no case to answer.� If they agree they may dismiss the case without the defendant having to provide his version of events.
