The issue, in this particular case, is not the accuracy of the information provided by the applicant, but rather the wrongful interpretation of it's relevance as assessed by the COD issuer.
Now, I absolutely agree. The COD ought be revoked.
However 5 years have passed and the car has changed hands, at least once but possibly more, with the COD no doubt forming a sizeable part of it's value. Perhaps the window of opportunity has gone?
In which case, where does it leave the rest of us?
