“29.— Exceptional circumstances (1) A claimant who does not have limited capability for work as determined in accordance with the limited capability for work assessment is to be treated as having limited capability for work if paragraph (2) applies to the claimant. (2) This paragraph applies if— (a) …; or (b) the claimant suffers from some specific disease or bodily or mental disablement and, by reasons of such disease or disablement, there would be a substantial risk to the mental or physical health of any person if the claimant were found not to have limited capability for work.”
“39. The correct approach has been identified by Deputy Commissioner Paines in CIB/360/2007: “17. The degree of detail in which [the consequences of a finding that the claimant is capable of work] will need to be thought through will depend on the circumstances of the case. A tribunal will have enough general knowledge about work, and can elicit enough information about a claimant’s background, to form a view on the range or types of work for which he is both suited as a matter of training or aptitude and which his disabilities do not render him incapable of performing. They will then need to decide whether, within that range, there is work that he could do without the degree of risk to health envisaged by regulation 27(b). 18. Regulation 27(b) requires one to start by identifying a disease or disablement; the next stage, it seems to me, is to consider the nature of any health risks posed by that disease or disablement in the context of workplaces that the claimant might find himself in, with a view to answering the question whether any such risk is substantial.”
