"We consider this analysis must be correct. We do not consider it appropriate or indeed competent in the context of this legislation for an employer to put the issue of justification before the tribunal where in fact he never even attempted during the currency of the employment to take any steps which would base justification for the ultimate discriminatory act, that is to say, considering or at least applying his mind to what should be done to accommodate the disablement. We do not consider that the legislation contemplates attempts by employers on a hypothetical basis to justify an act subsequently held to be discriminatory which they did not at the time consider to be such, because they were unaware of the existence of the disability, upon the ultimate aim of seeking to establish that there was nothing in fact they could have done, a situation not unlike the exercise which is sometimes undertaken in redundancy cases where the employer seeks to maintain that even though he failed to consult, a consultation would not have made any difference. We do not consider that approach as appropriate in the context of this legislation where the issue of disability and discrimination is disputed as a matter of fact in the mind of the employer. The situation would be different if, being aware of the disability, the employer did nothing because he considered that there was nothing that could reasonably be done."
