Where is this "owners name" recorded? The only "recorded" information for a vehicle is the Registered Keeper (RK). The RK is the person or business responsible for taxing and registering the vehicle.
The RK and the "owner" do not necessarily have to be the same person and any inference that they are is easily challenged in court.
As this is a supposed bylaws penalty (it isn't as it is fake), there is a lack of definition for "owner" in the bylaws. The term "owner" is mentioned but not defined in the byelaws, and so it creates ambiguity.
Without a clear legal definition it is unclear who the byelaw intends to hold responsible—whether it is the person with legal ownership, the registered keeper, or the person in charge of the vehicle (driver).
In criminal cases, as this would be if prosecuted in the magistrates court, such ambiguity can be used in the defendant’s favour because of the principle that laws must be clear and precise to hold someone liable.
In other words, ambiguity in the term "owner" would render the prosecution's reliance on this term insufficient to meet the criminal standard of proof, which in this case would be "beyond a reasonable doubt".
