I do no see how the decision by an Air Commodore to publish a limitation such as "Absolutely no doubt whatsover" can be deemed to limit the Authority of his Superiors, including the Chief of the Air Staff, in the execution of their duties.
The question, surely, is who gave the Air Commodore permission to impose such a limitation? If such a limitation was not actually approved in writing by the Chief of the Air Staff prior to publication then the validity of such a limitation is undoubtedly called into question.
