So, what was the real decision on your case? You may have bollixed yourself by signing up for JSA, thereby declaring yourself fit for work.
Not necessarily - I can see where you're coming from but when I got kicked off the sick, I signed on for JSA - And continued to claim JSA even after I'd won my appeal to get back on the sick until my sick got re-instated. Claiming JSA while the OP waits to hear about his/her ESA will have no bearing on whether he/she ends up getting back on ESA.
E2a - The above doesn't read very coherently - Hope people can make sense of it.
