"The case is really marked by the defendant's inability to co-operate with the obligations which the ownership of a motor vehicle imposes on the citizen these days. There is no doubt, in our view, that he failed to provide the information required under section 172(2)(a). We have had to consider whether the statutory defence under section 172(4) applies. What we have been told by the appellant in the witness box, where he has been extremely frank, is that although the car is registered at 79 Deer Park Gardens, Mitcham, he himself is not there on any what might be regarded as regular basis. He told us about his work commitments which take him down to Herne Bay and he has mentioned other addresses where he resides from time to time. But perhaps the most significant aspect of his evidence is that he told us at one point, and I quote: 'I have made it my business not to be at the registered address' and he explained that against the background of receiving letters from the Child Support Agency. So here is a man who, although he has his car registered at 79 Deer Park Gardens, is not there often and makes it his business not to be there often. In those circumstances it is hardly surprising if he says, and we accept what he says about this, that he did not get the letters. He talks about another person being at that address, being on hand to open letters as and when needed, but the reality is that the section, that is to say section 172, imposes a heavy duty upon a motorist. Once he has given an address, that is the address at which he must be available to receive communications such as notices of intended prosecutions and it does not lie in the mouth of an appellant or a defendant in the magistrates' court simply to say, 'I haven't been home much and therefore I haven't received these communications'. As I say, the Act, section 172, places a duty, which these days has to be interpreted strictly, upon the motorist that when he given an address as the registered address of his motor car, to make sure that important documents relating to that motor car when sent to that address will be received by him. For those reasons we reject the appeal."
