There are two issues in this appeal. The first is how Rule 10 of the Employment Tribunal Rules 2013 (“ET Rules”) applies when claims are brought by a number of prospective claimants on the same claim form. Rules 10 and 12 of the ET Rules ensure that most claims in which a prospective claimant, who is not exempt, has failed to undertake ACAS Early Conciliation (“EC”) are weeded out before service of the claim form on the respondent.

The second issue is by whom, and against whom, a cross-appeal can be brought.

Litigation is to be avoided where possible. Reasonable settlement of claims is to be encouraged. Many litigants come to appreciate this with the benefit of hindsight. Even those who are successful are often not as successful as they wanted, may be subject to criticism, and can find that the costs of the litigation in terms of time, money and emotion makes the victory Pyrrhic. That said, litigation is sometimes unavoidable. Litigation may be necessary to establish individual rights and determine points of general legal principle. But litigation should be seen as a last resort, not a first port of call.

For a number of years, provisions have been in place to try and persuade parties to resolve their differences without recourse to litigation. That is the fundamental purpose of EC. The substantive EC scheme adopts a relatively light touch. Individuals are required to do little more than contact ACAS and obtain an EC certificate. They are not required to engage in conciliation at all if they do not wish to do so. They are taken to water, but not forced to drink.

By comparison, the gatekeeping procedural rules are, in places, a little heavy-handed. Individuals who have fully complied with the substantive requirements of EC can find that because of an error in completing the claim form the claim must be rejected, sometimes in circumstances in which any resubmitted claim is likely to be out of time. That is why the rules have been somewhat relaxed by amendment. Nonetheless, if unambiguous mandatory provisions of the procedural scheme require rejection of the claim that outcome cannot be avoided, even if the application of the provisions may bring to an end a claim brought by a person who has complied with the substantive requirements of EC. However, in other cases, where the wording of the provisions permit, the courts will seek an interpretation that advances the purpose of the substantive EC scheme and does not place unnecessary obstacles in the way of prospective claimants obtaining access to justice.

So far as is relevant to this appeal, and in summary, the substantive elements of EC are as follows. Section 18A(1) Employment Tribunals Act 1996 (“ETA”) requires that before a prospective claimant presents an application to the employment tribunal to institute relevant proceedings (i.e. proceedings that fall within the scope of the EC scheme) prescribed information must be provided to ACAS in a prescribed manner. Paragraphs 1 to 3 of the schedule to the Employment Tribunal (Early Conciliation: Exemptions and Rules of Procedure) Regulations 2014 (the regulations will be referred to as the EC Regs and the rules set out in the schedule as the EC Rules ) set out the prescribed information and prescribed manner in which it should be provided to ACAS. Section 18A(3) ETA provides that the appointed conciliation officer shall, during the prescribed period, endeavour to promote a settlement. The period during which the conciliation officer is required to endeavour to promote a settlement is prescribed by Rule 6 EC Rules . The manner in which the conciliation officer should endeavour to promote a settlement is set out in Rule 5 EC Rules . ACAS must make reasonable attempts to contact the prospective claimant but should only attempt to contact the prospective respondent if the prospective claimant consents. If the conciliation officer concludes during the prescribed period that a settlement is not possible, or the period ends without a settlement, the conciliation officer shall issue a certificate, in a prescribed manner, to the prospective claimant: Section 18A(4) ETA . The prescribed certificate is called the EC Certificate (Rule 7 EC Rules ).

The information the EC Certificate is required to contain is set out in Rule 8 EC Rules (the name and address of the prospective claimant and respondent, the date conciliation commenced, the unique reference number given by ACAS to the EC Certificate, and the date of issue of the EC Certificate).

Section 18A(7) ETA provides that a person can present relevant proceedings without complying with the requirement for EC in prescribed circumstances, that may include where “the requirement is complied with by another person instituting relevant proceedings relating to the same matter”, where “proceedings that are not relevant proceedings are instituted by means of the same form as proceedings that are” and in circumstances in which “ACAS has been contacted by a person against whom relevant proceedings are being instituted”.

Regulation 3 EC Regs provides that where another person has complied with the requirement for EC that a claim can be commenced without an EC Certificate where “another person (“B”) has complied with that requirement in relation to the same dispute and A wishes to institute proceedings on the same claim form as B”.

Regulation 3 of the EC Regs refers to “the same dispute” whereas the enabling provision, Section 18A(7) ETA , refers to “the same matter”. More significantly, Regulation 3 EC Regs requires that the person who has not complied with EC “wishes to institute proceedings on the same claim form ” [emphasis added] as the person who has complied with EC, which is not a necessary requirement of the enabling provision. Rule 9 ET Rules places significant limitations on the circumstances in which claims can be brought on the same claim form, that I will consider in more detail when analysing the appeal. It is to be noted that Regulation 3 EC Regs creates a link between a person being able to take advantage of another person having complied with EC and that person being able to bring a claim on the same claim form as the person who has undertaken EC.

As stated above, Rules 10 and 12 ET Rules are designed to weed out claims of prospective claimants who are required to comply with EC, but have not done so. I shall consider the provisions in detail when analysing the appeal.

This appeal arises in long-running litigation in which employees of the respondents are claiming they are entitled to pay equal to employees in other roles. The claims commenced in 2015. The claimants work in a number of different jobs and compare themselves with comparators in a range of different roles. In addition to claims brought by women seeking equal pay with men, there are claims brought by men who bring contingent claims which rely on women colleagues undertaking the same job establishing that they are entitled to pay parity with male comparators, after which the men who carry out the same role as the women contend that they will be entitled to pay parity with the women.

As is common in litigation of this nature, the claims have been brought on a number of multiple claim forms. All of the claimants have complied with EC. They have not sought to rely on the exemption to EC on the basis that other employees have complied with EC and they are bringing a claim in the same dispute on the same claim form.

At the time the claimants were undertaking EC, ACAS adopted a number of different approaches to EC certificates. In some multiple claims ACAS only issued a certificate with a single multiple EC number (an M number). In some cases ACAS provided a certificate with an M number and an individual EC number (an R number) for one of the prospective claimants, but no other R numbers for the other prospective claimants that appeared in a schedule attached to the EC Certificate. In other cases, ACAS issued an EC Certificate with one M number and an R number for each of the prospective claimants that appeared on the schedule to the EC Certificate.

The solicitors representing the claimants adopted a variety of approaches on different claim forms when setting out an EC Certificate number, or numbers. A claim form only has one box for each respondent in which an EC number can be entered (e.g. box 2.3 and 2.5). For electronic submission there is only one claim form. For submission by post form ET1 (for single claimants) and ET1A (for multiple claimants) only have one box for each respondent that specifically allows the insertion of an EC Number. Form ET1A has extra pages to add the names and addresses of additional claimants, but does not provide boxes for EC numbers for each of the additional claimants. That said, in all versions of the ET1 there is a box for additional information which can be used in multiple claims to enter the EC numbers for each individual claimant.

When the claim forms were presented it appears that the staff of the ET did not consider that an issue was raised under Rule 10 ET Rules and so did not refer the claim forms to employment judges for consideration under Rule 12 ET Rules . This is, perhaps, unsurprising, as an EC number was included in each claim form.

When the claims were served on the respondents they did not initially take a point about EC. The point was taken by the respondents some years after the claims had been served. It was considered at the fifth preliminary hearing in the combined claims together with a number of other issues (reading 28 February and 2 March, then hearing on 3, 5 & 10 March 2020).

In a conspicuously thoughtful and careful judgment, Employment Judge Camp permitted all claims to proceed where there was an EC number, or EC numbers, on the claim form that appeared somewhere on an EC Certificate on which the name of the claimant also appeared. So, for example, if only an M number was given on the claim form, provided the claimant's name appeared in the schedule to the EC Certificate that had the M number on it somewhere, even if the claimant had also been given a separate R number, the claim was permitted to proceed. The one group of claims Employment Judge Camp held should be rejected were those of claimants whose names appeared on an EC certificate and no number appearing on that EC Certificate was included anywhere on the claim form. So, for example, there were claim forms in which the name of a lead claimant appeared at section 2, together with an EC number for an EC certificate on which that lead claimant’s name appeared, but there were claimants on the schedule attached to the claim form whose names did not appear anywhere on that EC Certificate, or on any EC Certificate a number for which was set out anywhere on the claim form.

The decision of Employment Judge Camp for this group of claimants was appealed. They were referred to as the Category 4 claimants. The appellants contend that it is sufficient if one EC Certificate number is given on the claim form for any claimant who brings a claim on the claim form.

The respondents seek to cross-appeal in respect of the refusal to reject the claims of other prospective claimants. They contend that it is necessary for each claimant that their name and an EC Certificate number specific to that claimant appears on the claim form. This gives rise to the question of whether the respondents can cross-appeal against claimants in a multiple claim who have not themselves appealed against the decision.

As I noted in the introduction it is common for even successful parties to be dissatisfied to some extent with a judgment because, for example, they have not succeeded in all of their claims. All parties to litigation may, to a greater or lesser extent, be dissatisfied with the outcome. Parties often conclude that despite some dissatisfaction, they are prepared to draw a line under the matter and do not seek to appeal. Bringing a conclusion to litigation is to be encouraged. There are very strictly enforced time limits for appeals to the EAT. Where an appeal is brought within time a respondent to the appeal may cross-appeal against any determination that was adverse to it. This is because while the respondent might have decided to let sleeping dogs lie if there was no appeal, if an appeal is brought they may wish to ensure that their dog is in the race.

The respondents seek to rely upon the decision of Langstaff J (P) in Basildon and Thurrock NHS Foundation Trust v Weerasinghe UKEAT/0397/14/RN:

The respondents rely on the reference in paragraph 14 to a cross-appeal not being limited to a matter that is “intrinsically linked” to the subject of the appeal itself. However, I consider the key passage is in paragraph 15, where it is noted that the obvious meaning of the word cross-appeal, is an appeal which “arises in response to an appeal”. I consider it is clear that a cross-appeal is brought by a respondent to an appeal against the appellant.

Rule 5 of the Employment Appeal Tribunal Rules 1993 (as amended) provides that the respondents to an appeal shall be the parties, other than the appellant, to the proceedings before the employment tribunal. Accordingly, the individuals against whom the respondent seeks to cross-appeal are not appellants in this appeal, they did not bring an appeal themselves, they are respondents to the appeal.

I do not consider that there is any proper basis upon which a respondent to an appeal can bring a cross-appeal against another respondent. That conclusion flows from the natural meaning of the words “appeal” and “cross-appeal”. It is consistent with the underlying approach that a party should decide, within the time allowed to bring an appeal, whether to accept the first instance outcome, even though it may not have been all that was wanted, or appeal. Where a party has taken the pragmatic approach of choosing not to appeal they should not find themselves deprived of the protection of the relatively short time limits for the opposing party to bring an appeal, because some other party has decided to appeal the decision made against them. Accordingly, I conclude that the respondent is not able to cross-appeal against the determination in the case of the claimants who were permitted to proceed with their claims. When allowing permission for the cross-appeal to proceed HHJ Wayne Beard specifically did so, subject to the argument that this was not a valid cross-appeal, which I find to be the case.

I will now go on to consider the substantive appeal. For reasons that will become apparent my conclusions mean that the cross-appeal would have failed in any event.

The key provision in this appeal is Rule 10 ET Rules

It should be noted that in a commonly used compilation of employment statutes Rule 10(1)(c) is misquoted, in that it refers to the claim form not containing “all of the following” whereas the requirement is to contain “one of the following”. I mention this as the incorrect formulation has been referred to in some appellate authorities. The error is easy to spot because it would be illogical to require the provision of all items referred to in Rule 10(1)(c) as they are disjunctive.

The appellants’ point is, at heart, very simple. A claim form shall be rejected if it does not contain each claimant’s name and address and each respondent’s name and address. In contrast, the claim form is only required to contain, so far as is relevant, an EC number. The appellants contend that the wording of the provision simply requires that one EC number be provided. The respondents contend that for the scheme to work the provision must be read as requiring that an EC number be provided for each claimant and, at the very least, there must be an EC number on the claim form that appears on an EC Certificate on which the claimant’s name also appears.

Rule 10 ET Rules works alongside Rule 12, which at the relevant time provided:

The provision has subsequently been amended to allow for errors in quoting an EC Number on the claim form, permitting an employment judge to exercise a discretion not to reject a claim form even where “the early conciliation number on the claim form is not the same as the early conciliation number on the early conciliation certificate” if “the Judge considers that the claimant made an error in relation to an early conciliation number and it would not be in the interests of justice to reject the claim”: Rule 12(1)(da) and 2ZA.

In construing the phrase “an early conciliation number” in Rule 10 of the ET Rules the respondents seek to rely on the Interpretation Act 1978, pursuant to section 6 of which “words in the singular include the plural and words in the plural include the singular”.

The employment judge favoured the respondents’ approach, considering that it was consistent with the underlying purpose of the scheme to ensure that the employment tribunal could check in the case of each claimant whether EC had been undertaken. The employment judge considered the matter at paragraphs 64 to 66:

Category 4 claims
