My husband was getting DLA for over 12 months and was told that he had to fill out another form, a doctor was sent out to assess him, the doctor put that he could walk a lot further than he can, and he lost his DLA we went to appeal and was still denied it.
The organisation that represented us at the appeal said that they had taken the doctors word against ours and the only next step would be to say that the doctor or the panel had acted unlawfully, that is a pretty big accusation, nobody was saying it was unlawful but possible a mistake.
