It's nothing to do with being rich.
He need not have employed anyone and could have resolved it with 30 seconds at a PC or even his phone.
The police have 14 days to start legal proccedings and it is so prescribed for a very good reason.
If you got a notice from the police that said, who was driving your car on a date 15 months ago, would you know? What about 15 weeks ago? It would be unfair to face 6 points and a big ol fine for not being certain who was driving.
So what is fair. That point has been decided as 14 days (long enough for the state and it's huge resource to pull it's finger out, short enough to give you a chance to remember or investigate). Yes it's only 1 day out, but then the rules are in place to protect the people against the state. If 1 day out is alright then why not 2, if 2 is ok then why not 3, I could go on.
The beauty of it (and the irony of how it is reported and received) is that these rules are the same for the everyone, rich or poor. You come in to my Court and show me the police are one day out, I'm throwing the case in the bin, doesn't matter if you have the best lawyer or none, it's the law.
