Failure to notify or being deliberately obstructive could see both the registered keeper and driver getting points regardless.
I fully agree. However the law allows you 28 days to respond to a postal NIP/S172, so taking 25 days to comply cannot be construed as obstructive. I suspect what Jason is being coy about is a verbal S172 where you don't get 28 days - and you might not even get 28 minutes to respond.
Notwithstanding that the mere issuing of the NIP constitutes notification... ie they are automatically generated and posted The onus is on the receiver to prove that they never received it.
Not strictly true - it's called a rebuttal presumption but I agree the effect is that you have to have some pretty good evidence as to why it never arrived (in time).
As for automatically generated - well someone is supposed to review the photos and not just issue NIP's willy-nilly
. And someone has to enter the details from the NIP responses so that new NIP's are issued to the nominated person. There is no requirement to use the form they supply, [Jones v DPP [2004] EWHC 236 (Admin), CO/5123/2003 May L J.. Nelson J.] so someone might have to read the multi-page letter supplying all the information requested by the chief of police.
However, I doubt it's a good idea to pi55 of the SCP and mark yourself as a trouble maker if you're hoping for a timeout.
