Well done joe, great find and great piece of caselaw.
Wasn't trying to sound too bleak, that's why I suggested to continue with the letter of reconsideration before spending money on professional help.
This one went outside my experience so I wanted to be very cautious.
How terrible that the ECO knew it was not deception but continued anyway.
Although probably the ECO has no authority to grant a visa on a 'misrepresented' application.
There you have it sim&lil caselaw already done for you.
Thanks to joe things look a lot better.
