" It is common ground that this system operated to disadvantage the access of ethnic minority workers to the more desirable jobs, both because they were under-represented on the south estate as compared with the north estate and because they were particularly under-represented in general services on the south estate, where the better jobs predominated ."
" (1) A person discriminates against another in any circumstances relevant for the purposes of any provision of this Act if – (b) he applies to that other a requirement or condition which he applies or would apply equally to persons not of the same racial group of that other but – (i) which is such that the proportion of persons of the same racial group as that other who can comply with it is considerably smaller than the proportion of persons not of that racial group who can comply with it; (ii) which he cannot show to be justifiable irrespective of the colour, race, nationality or ethnic or national origins of the persons to whom it is applied; (iii) which is to the detriment of that other because he cannot comply with it. "
" one must take all the circumstances into account. This is a test of materiality " and (per Lord Scott at paragraph 105) that this: " must be applied by considering the issue from the point of view of the victim. If the victim's opinion that the treatment was to his or her detriment is a reasonable one to hold, that ought, in my opinion, to suffice … [ W ] hile an unjustified sense of grievance … cannot constitute 'detriment', a justified and reasonable sense of grievance … may well do so. "
" We construe the phrase 'because of' in the subsection as meaning 'as a result of' and we are reinforced in this view by the fact that there are authorities that would suggest that, even if there is a physical detriment, if it is sufficiently trivial not to be material it does not apply. "
" Our conclusion upon the matter is this, that there is nothing in the language of the statute to exclude the consideration of a new point of law but that it would in almost every conceivable case, as the National Industrial Relations Court said in GKN (Cwmbran) Ltd v Lloyd[1972] ICR 214 , be unjust to do so. The case which one can conceive as a case in which it would not be unjust to do so would be a case in which there has been some deception on the part of the respondent to the appeal which entitles the appellant to say, "
" The Tribunal inadvertently came across and read a list of jobs that had been advertised in the south estate during the period November 2001 to November 2002 when trying to trace an earlier document to which reference had been made. We told the parties about this, but heard no further evidence relevant to it ". (ii) Paragraph 6(xx): "
" In order to do its best, the Respondent had made a guess at what might be relevant information and had provided that which was in the bundle concerning jobs advertised in general services on the south estate in the three or four months, November 2001 to February 2002. This period was consistent with evidence from the Respondent's witnesses and that of the Applicant, to the effect that union representatives tended to stay in post as long as possible during a redeployment process. The Applicant had confirmed that he would have wanted to do that, unless a gold-plated job had come up. So the last few months of the redeployment year was a proper period to be regarded in order to ascertain whether the Applicant had, in fact, suffered any detriment from the application of the progression arrangement. This information had been ignored by the Applicant and his representatives during the course of the hearing. There had been no suggestion at any stage that the Applicant would have wanted or been interested in any of the jobs there identified. The Applicant had given no evidence about them and none of the Respondent's witnesses (or indeed the Applicant's witnesses) had been questioned about them. In circumstances where the Applicant had effectively chosen before and during the hearing not to pursue a particular course, it was not proper for the Tribunal to adopt a line that would prejudice the completion of the hearing in order to encourage the Applicant to take a course that he had apparently deliberately not pursued.
