After spending the weekend in North Wales and a couple of trips to Manchester.
Tonight he was boxed in by 3 police cars on the M6 Birmingham!
Had to show his licence and go to the police station this time!
He will have to inform DVLA for a new plate.
Ha! they love the practice..
On a serious note, clearly the PNC marker is a serious one as they are ranked in order of priority & I'm guessing that he wouldn't attract that much attention for an expired tax disc!!
A paperwork trail copy kept with him whilst driving would be my advice, with all correspondence to DVLA sent with proof etc.
The Police are quite legally acting upon information available to them, but they are acting wrongfully if it can be proved that this information is false or out of date.
The first time the Police investigated his use they had a statutory duty to inform DVLA of the current user/owner. There will always be a time lag but after a reasonable period plus his own protestations to DVLA, the record should be amended.
If this continues, I would seriously advise he seeks recompense for harassment and/or wrongful arrest. Sadly, he's not the only one this happens to due to DVLA being a separate entity..
