NIP issued way after 14 day period

Hi everyone,

Asking for a friend.

A Notice of Intended Prosecution (NIP) was issued more than three months after the alleged offence, well outside the 14-day limit. The police are now saying the first NIP was sent to an incorrect address taken from the PNC, even though the DVLA records were correct and up to date and well as the V5C. They later resent it to the correct address months later. Does she have a defence that reliance on the Police National Computer doesnt fulfill statutory obligation.

Any recommendations on how she could tackle this would be much appreciated.
