My father has been receiving higher-rate disability allowance and recently had to reapply. He has just heard that he has been refused higher-rate and will receive lower rate. This means he will lose his blue badge. He really needs this as he is incapable of walking any distance without some form of support (he has severe arthritis through his body and damage to disks in his spine which means he has limited sensation in his limbs).
Can anyone advise me on how to appeal?
