Court records show Khan was prosecuted by the DVLA after the annual tax on the blue Nissan Micra, which was first registered in 2002, ran out in September last year.
The DVLA said the vehicle was spotted untaxed on 24 January and told the court that his name and date of birth appeared against the car on official records held by the government.
The agency said a letter asking for confirmation of the identity of the car owner, which was sent to the wrong address, went unanswered in January, leading to a criminal prosecution on 18 August after no plea was entered to the charge.
The court also sent a record of conviction to the Gordon Ramsay restaurant, ordering Khan to pay the £340.84 court bill within 28 days or face the prospect of increased fines, bailiffs, or even “a warrant for your arrest to bring you to court”.
The DVLA said it was reviewing the case and investigating the circumstances of the prosecution.
Defendants who believe they have been wrongly convicted of a crime in their absence can apply for the case to be reopened, typically by appearing in person in front of a judge to make a statutory declaration.
Khan could argue that he did not know about the criminal case because the letters were addressed to the wrong building.
Once reopened, he could petition the DVLA to withdraw the prosecution if it can be shown that he was wrongly accused, or enter a not guilty plea.
Alternatively, the DVLA could apply to the court for the case to be reopened.
