I've just received a bundle for a claim made wef November 2004 decision January 2005. There was a previous, hotly disputed refusal ultimately unsuccessful om a claim wef January 2004 decision March 2004. Appeal papers for new claim include material from previous claim, including the realyl horrible bit subject to the hot dispute.

I intend to say that due to gradually deteriorating condition that's rendered irrelevant, but is there any neat caselaw that says it MUST be irrelevant??

Any help much appreciated.
