I'm not necessarilly sure that the correct approach when going to court would be to say they lied. It's more their incorrect interpretation of the application and also the fact that they missed things in the supporting documentation.
My lawyer even asked me the other day did we actually send photographs with the application because she found it strange that on 2 occassions they have stated that we never supplied photographs.
I took our original application over to her which included 28 photographs stuck in twos on A4 paper with writtten explanations of where when and who were in them. I also said that I found it even stranger that they have said on 2 occassions they havent seen my passport and yet they supplied a copy of it with the appeal papers.
D day is getting closer now so just hoping for a good performance from the lawyer and a Judgewho takes his time and studies the application.
The bottom line is I really wouldn't have appealed if I didn't think they got it wrong. Between the cost of appealing and my solicitors cost it comes to quite a bit more than simply submitting another application.
