Or it could be a job for the Civil Service Ombudsman, but I think such a referal must come from a Member of Parliament.
Going back to fact that he last saw his licence when he used it abroad on holiday. Has he checked for it where he keeps his travel documents? In his suitcase? In his wash bag?
Given that he has a copy of his licence which, as well as showing a Driver Number, it should also show a Document Number. Assuming that these are issued consecutively, are the DVLA willing to confirm that the numbers both preceeding, and following were in use, and to whose licence the interim Document Number relates?
On reflection, I suggest his main mistake was to inform his insurers. Insurance invariably covers a person who, “…holds, has held, and is not disqualified, from holding a Driving Licence…”
Obviously he is not disqualifed.
Although he no longer holds a D.L. (in the sense that he cannot find it), there is documentary evidence that he ‘has held’ a D.L.
I was once involved with a situation where an employee was asked if he could take the Company van out to do a little job. They hadn’t checked, and he never volunteered the information, that he had never passed a Driving Test. Inevitably, he had a ‘bump’.
This was in the days following when D.L. records were kept by local authorities and ‘renewals’ were updated at the DVLA. Hence the record of him holding a Provisional had been destroyed by the Local Authority, and he did not feature on the DVLA database.
The matter was resolved when I eventually dug up an old Court Conviction against him for “Unaccompanied Leaner”, and “No L’s”, which served to establish he ‘had held’ a D.L. and that the accident was covered by the insurance in force for the vehicle.
And it saved the company from being prosecuted for “Use without Insurance.”
