While I agree with Chug and Fitter, it has to be said that even today the official line in MoD is that it is not an offence to issue an order to make a false written declaration about airworthiness or financial probity. Despite Haddon-Cave, it remains an offence to refuse to obey such an order. Bizarre, but true, and supported in writing at Ministerial level.
And, as I've said before, the issue is largely academic as I have the Ministerial briefing stating I am the only person in MoD who believes the airworthiness and financial regulations should be implemented properly and such "illegal" orders should not be issued.
Of course, the people who wrote the Ministerial briefings were the very people who made the rulings in the first place. A well known principle familiar to anyone with even basic knowledge of the Mull of Kintyre case!
This rather makes one wonder what the MAA does.
