where a person suffering from a condition which results in him being severely disfigured is turned down for a job, it does not follow that there must have been unlawful disability discrimination just because severe disfigurement is automatically regarded as a "disability" for purpose of the Disability Discrimination Act 1995. This would follow if the reason he was turned down for the job was his severe disfigurement but does not follow if he was turned down for some other reason - even if that other reason is related to the condition which caused the disfigurement.

and an example of:-

one of the ways in which the disability anti-discrimination rules operate differently from other anti-discrimination rules - to take an analgous example, it clearly would be unlawful sex discrimination to refuse employment to a pregnant woman even though the reason for the refusal is not her pregnancy but is because of the likelihood that she will take time off work (see Webb v Emo Air Cargo (UK) Ltd 1995 ).
