“It is unusual for an appeal from an interlocutory order of an industrial tribunal [as employment tribunals were then called] to reach this court. An appeal from an industrial tribunal to the Employment Appeal Tribunal only lies on a question of law. An appeal from the appeal tribunal to [the Court of Appeal] may only be brought on a question of law and with leave. Interlocutory orders are made by an industrial tribunal under theIndustrial Tribunals (Constitution and Rules of Procedure) Regulations 1993 [now replaced by theEmployment Tribunals (Constitution and Rules of Procedure) Regulations 2013 ] which confer broad discretions on tribunals in procedural matters. The exercise of a wide discretion rarely gives rise to a question of law. Unless there is a reasonable prospect of showing that the tribunal has misdirected itself in law, erred in principle or arrived at a decision which is plainly wrong, leave to appeal to this court will not be granted against the exercise of a discretion. …”
“(1) Proceedings on a complaint within section 120 [which this is] may not be brought after the end of - (a) the period of 3 months starting with the date of the act to which the complaint relates, or (b) such other period as the employment tribunal thinks just and equitable. … (3) For the purposes of this section - (a) conduct extending over a period is to be treated as done at the end of the period; …”
“48. … legally more precise way of characterising her case [that of a Metropolitan Police officer who complained of several acts that she said were linked by institutional racism] than the use of expressions such as ‘institutionalised racism’, ‘a prevailing way of life’, a ‘generalised policy of discrimination’, or ‘climate’ or ‘culture’ of unlawful discrimination.”
“A preliminary hearing may be directed by the Tribunal on its own initiative following its initial consideration (under rule 26) or at any time thereafter or as the result of an application by a party. …”
“39. To the extent that any specific complaint appears to be out of time the Claimant contends that it will be necessary to consider the merits of her complaints to determine whether a. There is conduct extending over a period (for the purposes of s.123(3) … and/or b. Whether it would be just and equitable to extend time …”
“8. This is a case where, depending on the facts found, the claimant may establish an underlying discriminatory state of affairs. In some cases a respondent can show that this is improbable, for example where several different decision makers have made allegedly discriminatory decisions at different times, but the grounds of claim here allege an underlying continuity of approach by Mr Aranguena from late 2012, for example, and the continuity of discriminatory decisions from 2009 relating to pay and grade. Whether there was a discriminatory state of affairs, so that conduct extended over a period which had not ended before the relevant time limit, is something a tribunal will have to decide after hearing the evidence and deciding whether this was the case, as made clear in Hendricks … Whether a state of affairs is discriminatory is fact specific.”
“10. Even if some - or many - of the earlier claims are ruled out of time, it may still be necessary for the tribunal to hear evidence of those past events in order to make findings on the reason for later treatment, as often happens where the same managers have been involved in some years, or where a discriminatory culture is alleged, as here. Thus even if successful in striking out some claims, a preliminary hearing might do little to shorten the final hearing time.”
“… [The Judge] said that there might be a continuing act and that this might need to be decided in the light of the evidence (para 8). That was not correct. The question whether there is a continuing act is one which depends on the pleaded case. …”
“… The preliminary issue procedure is less appropriate in cases where the isolation of a point of law or fact separates it from the context of the whole case and involves a risk of distorting the dispute, eg by restricting the scope of enquiry to such an extent that the tribunal reaches a decision without a full appreciation of the case as a whole. …”
“36. … Even if it is decided at a pre-hearing review or other preliminary hearing that there is no continuing act or series of similar acts, that will not prevent the complainant from relying evidentially on the pre-limitation period acts to prove the acts (or failures) which establish liability. …” (Indeed, there is appellate encouragement at the highest level (see Anyanwu v South Bank Student Union[2001] ICR 391 ) for this to be so in the case of alleged discrimination as is this case.) Mummery LJ went on to say, continuing the citation from his paragraph 36: “ … It will in many cases be better to hear all the evidence and then decide the case in the round, including limitation questions, on the basis of all the evidence: see, for example … Hendricks … particularly paras 48 and 49, regarding the approach to multiple acts alleged to extend over a period.”
“I agree with Mummery LJ that the appeal should be allowed. It is not helpful or sensible, in the present case, to try to decide on a preliminary basis without evidence whether a number of acts, or failures, do or do not constitute a series of similar acts, so that the complainant can claim for detriment suffered by him as a result of those which happened more than three months before the issue of his proceedings. This is the equivalent of a striking-out application. It seems to me that this is rarely likely to be a sensible approach in relation to a discrimination claim.”
“16. … often difficult to segregate in a wholly compartmentalised way a single issue … from other material that may have relevance to the matter to be decided.”
