nor will it legally be a defence should anyone be charged with failing to comply with the provisions of the Act.
I recall someone here (who I know is a barrister, but not Tudor Owen) posting on this general subject. Ignorance is no defence but if the Govt (the CAA) publishes something which is wrong, it's a reasonable defence because the public has a reasonable entitlement to a correction.
The Plod won't give a damn of course and if you make a fuss they will arrest you and lock you up, but that is as far as it can possibly go. I can't believe anybody would get convicted, because you have a right to a solicitor and he will turn up the relevant page and show it to them.
However, better to bring this into the open before somebody does get locked up.
