This is your personal vehicle I presume?
Is there any reason you cannot say who was driving then? I realise it was sometime ago but we can all ascertain who was driving our personal vehicle?
No, but the law requires you to investigate.
If you did so, why could you not say?
Yes, I understand. Why could you not ascertain who was driving? I know you won't know offhand. Why can you not investigate?
Ok. What is the date of the offence and the date of the original NIP?
