There are certain exceptions to the rule concerning delivery of NIPs. An important one (as far as you are concerned) is:
�Failure to comply [with the 14 day limit] is no bar [to the prosecution or fixed penalty proceeding] where the police could not with reasonable diligence have ascertained the name and address of the accused in time for service of the summons or notice within the 14 day period, or the accused contributed to such failure�.
This is particularly relevant where Company cars are concerned. The issue really is has the Camera Partnership acted �with reasonable diligence�? Has it really taken them since July, acting with reasonable expediency, to track the driver down? Or has the matter been sitting in somebody�s in-tray for a few months because it was less than straightforward?
However, this may be irrelevant. There is an absolute time limit on summary offences of six months from the date of the alleged offence. No further allowances are made for tracing defendants etc. Before the six months is up the �laying of information� � which has to include the identity of the accused - must be put before the magistrates� court for a summons to be issued (although the summons does not necessarily have to have been issued in that time).
It seems unlikely from what you say that this has been done. I imagine the NIP also includes a provisional offer of a fixed penalty and this has to be turned down before any court proceedings (including the �laying of information�) begin. If it has not been done your parrtner can simply decline the Fixed Penalty offer. A summons cannot then be issued.
