“The Respondent’s management aspiration is that all pay scales should consist of 6 points, with progression within 6 years from minimum to maximum. The further aspiration is to achieve a pay system where progression is related to assessed performance, and not merely related to length of service.” 38. Faced as they were with a claim brought by a man who had achieved almost ten years’ service (including a period of part-time service before permanent employment) Ms Lewis asked rhetorically how the employers could advance as a legitimate aim, and how the Tribunal could adopt as a legitimate aim, that which had been originally adopted some years earlier, and from which the employers were seeking to move away at the fastest speed available to them. Ms Lewis placed reliance on the decision of the Court of Appeal in Wilson v The Health and Safety Executive[2010] IRLR 59 . She deployed that case as authority for the proposition that any indirect discrimination must be justified not only by reference to the legitimate aim of a policy or practice when adopted, but also at the time that it had been actually applied to the Claimant in question. 39. The difficulty for Ms Lewis’ submission, and thus in consequence for grounds 1 and 2 of the grounds of appeal, is that the Tribunal here were alive to the difficulties that this intended shift in approach posed for the Respondent employer on the justification question. They record that matter, the submissions of the parties upon that matter, and more importantly the evidence that they heard. At paragraph 25 of their judgment they say as follows: “Drawing these matters together, we find that the original scale represented the objective stated, that of rewarding service incrementally. We find that the Respondent has embarked on the complex task of modernising the Chaplain’s pay scale, among many other such scales, operating within the framework and constraints which we have described above. We accept and find that progress has been inherently slow as a result of the scale and complexity of the task, and has now been effectively stalled by government economic policy relating to pay in the public services.”
“In our Judgment, and forming our own view of the matter, we find that the Respondent has demonstrated that its defence of justification has been made out and that the claim fails. We have considered the objective as the single one of rewarding length of service and increasing experience, while at the same time managing an orderly and structured transition, over a period of time to the shorter, single pay scales described above. That is clearly a serious objective, which represents a real organisational need of the Respondent.” 40. In that context it is our unanimous judgment that the Tribunal has not lost sight of the need to identify the legitimate aim. It has identified, in the passages we have extracted, the employers’ aim at the material time and has described it as legitimate, even though the aim was shifting away from that which had underpinned the originally adopted and still currently applied pay scale scheme to one which the Respondent employer wished to move. We can identify no error in this respect by the Employment Tribunal. (vii) ‘Proportionate means’ 41. By grounds 3 and 4 of the Notice of Appeal, the Claimant contended that the Tribunal had erred on the question of whether the PCP represented a proportionate response to the impact of the legitimate aim upon persons such as the Claimant. More particularly, the submissions of Ms Lewis asserted that the Tribunal had erred in finding that the disadvantage caused to the Claimant was no more than was necessary to achieve the legitimate aim. Put shortly, her case was that the Chaplaincy group was a relatively small group of employees within the Respondent’s department. A relatively modest adjustment, in her submission, was needed to deal with or address the consequences of the application of the PCP. Moreover, the Tribunal had been offered the example of an adjustment to the treatment of a significantly larger group of Prison Service employees (psychotherapists) in whose case a suitable adjustment had been made in order to eliminate discriminatory treatment. Ms Lewis prayed in aid the observation made by Lady Hale in Homer at paragraph 25 to the effect that the answer to the justification question at least depends to some extent “upon whether there were non-discriminatory alternatives available.”
