Io540, There are no cases to provide any guidance. I agree with you I have never thought that it amounted to 'reward' but it was the position taken over the years by the CAA. Since it was mentioned again, and by someone I understand is a Magistrate' I thought I would do my best to put that old one away for good even if it meant giving my opinion free!
Whoever said, on this or another thread, that the CAA like 'grey areas' is correct. This is why there is so little authority to be found in decided cases.They seldom appeal if they loose because they can try again with another case later provided no higher court has taken the point away by prior decision.
They do not make the law and sometimes do not seem to like it very much. Then they publish CAPs which slightly distort the meaning of the rules and allow misconceptions to continue if they have a 'chilling effect' on behaviour that is legal but for some reason they want to discourage.
Please do not ask for examples because I have none off hand. However I have seen it over and over again during the last 30 years.
