Unless you have been appointed your husbands legal representative, and there are reasons why he cannot cannot attend a hearing, rather than being too ill on the day, then you will not be allowed to represent your husband in the way your are suggesting.
I am afraid that the Tribunal will want to hear your husbands explanation as to why he believes he meets the ESA Support Group criteria.
You can apply for a domicilary hearing, but these are quite rare, and you will need support from your GP that this is a requirement.
