"47. It follows from our findings above that the issue central to this case is whether or not the Respondent can justify the prima facie discriminatory pay scheme. The parties were essentially in agreement as to the proper approach to justification. We have had regard to all of the authorities provided to us but take as a convenient summary the relevant principles as set out in Chief Constable of West Yorkshire & another v Homer[2012] ICR 708 in the opinion of Lady Hale where she said: "19. The approach to the justification of what would otherwise be indirect discrimination is well settled. A provision, criterion or practice is justified if the employer can show that it is a proportionate means of achieving a legitimate aim. The range of aims which can justify indirect discrimination on any ground is wider than the aims which can, in the case of age discrimination, justify direct discrimination. It is not limited to the social policy or other objectives derived from article 6(1), 4(1) and 2(5) of the Directive, but can encompass a real need on the part of the employer's business: Bilka-Kaufhaus GmbH v Weber von Hartz , Case 170/84,[1987] ICR 110 . 20. As Mummery LJ explained in R (Elias) v Secretary of State for Defence[2006] EWCA Civ 1293 ,[2006] 1 WLR 3213 , at [151]: "". . . the objective of the measure in question must correspond to a real need and the means used must be appropriate with a view to achieving the objective and be necessary to that end. So it is necessary to weigh the need against the seriousness of the detriment to the disadvantaged group.""
"57. It seems to us that the aims of the Respondent cannot simply be described as cost cutting. That might have been the aim of central government in issuing a pay cap, but on a department level the aim was far more nuanced than that. The Respondent, like any private sector business, needed to live within its means. The measures it adopted were its means of doing so and not its objectives. As such we do not think that the Respondent is relying on cost to justify its discriminatory conduct. It was an absence of means which forced the Respondent to take the decisions it did but that is not the same thing. 58.In the circumstances we are persuaded that the implementation of the new pay policy was for the legitimate aims identified by the Respondent."
"The concept of 'legitimate aim' is taken from European Union (EU) law and relevant decisions of the Court of Justice of the European Union (CJEU) – formerly the European Court of Justice (ECJ). However, it is not defined by the Act. The aim of the provision, criterion or practice should be legal, should not be discriminatory in itself, and must represent a real, objective consideration. The health, welfare and safety of individuals may qualify as legitimate aims provided that risks are clearly specified and supported by evidence."
"Although reasonable business needs and economic efficiency may be legitimate aims, an employer solely aiming to reduce costs cannot expect to satisfy the test. For example, the employer cannot simply argue that to discriminate is cheaper than avoiding discrimination."
"Deciding whether the means used to achieve the legitimate aim are proportionate involves a balancing exercise. An Employment Tribunal may wish to conduct a proper evaluation of the discriminatory effect of the provision, criterion or practice as against the employer's reasons for applying it, taking into account all the relevant facts."
"The material is relevant to Ground 3 of the Appellant's Grounds of Appeal, in which it is alleged that the ET did not hear evidence from which it could have legitimately inferred that the pay policy operated by the Respondent from 2011 was a temporary measure. The Appellant contends that there was no evidence to support this inference and that this was not the Respondent's case at the hearing. Further, the Appellant argues that the ET failed to set out to the evidential basis for such an influence. The Respondent does not accept that this is the case. It contends that, inter alia, in his evidence, Jason Paskins advised that changes to the current system would be occurring in the near future."
"The new pay policy was crafted to distribute that pain in as fair and equitable a way as possible given the constraints the Respondent was subject to"
