"24. It is worth starting by spelling out the structure of the Rule. Rule 21(1) sets out the circumstances in which the remainder of the Rule is engaged. I shall refer to them compendiously as a case in which the claim, which to repeat may be an employer's claim, is undefended or uncontested. In any such case, Rules 21(2) and 21(3) both apply. 25. As to rule 21(2), that requires a Judge to decide whether, on the available material, a determination of the claim can properly be made, and, to the extent that it can, to issue a Judgment accordingly. Otherwise, a hearing shall be fixed. However, the Judge may, to enable such a decision to be made on paper, seek further information from either or both parties. Clearly, this is intended to enable a Judge in a straightforward case, if appropriate, to issue a Judgment in favour of a claimant without the need for a hearing, avoiding the expense, consumption of Tribunal resource and delay of having to have a hearing in a straightforward undefended case. Although the scope of the Rule is not confined to any particular type of claim, that most naturally and commonly occurs in relation to straightforward undefended money claims for wages, holiday pay and/or notice monies. 26. However, the Rule neither requires nor permits the Judge to enter Judgment simply because the claim is undefended and without giving any further consideration to the matter. As the words that I have emphasised reflect, the Judge needs to be satisfied that a determination can properly be made. Otherwise there has to be a hearing. That means, it seems to me, that the Judge needs to be satisfied, on the information contained in the claim form and any other documents or materials before them, and, in view of the claim being undefended, treating what the party advancing the claim says as undisputed fact, that the factual elements necessary to make good the claim in law are made out. 27. The Judge needs to be satisfied of that before granting a paper Judgment, whether on liability or, as the case may be, remedy. In order to carry out this task the Judge is empowered to require the parties to provide further information - and the use of the word 'parties' makes clear that this could be either or both of them. However, if this process does not resolve any uncertainty then a paper Judgment should not be issued and instead a hearing must be held. 28. I note also that pursuant to Rule 7, where there is relevant Presidential Guidance, while the Tribunal is not bound to follow it, it must have regard to it. It follows that, whenever considering what to do in a case to which Rule 21(1) applies, the Judge should consider the Presidential Guidance, even if they decide for some reason not to follow it in some respect. While much of that guidance may be said to be procedural in nature, it draws attention also to substantive issues that could, in a given case, affect the Judge's decision as to whether further information and/or a hearing is needed, such as whether the claim is clearly stated, where the burden lies and whether there is an obvious jurisdictional problem. It rightly suggests that if there is reasonable doubt about any material matter a hearing should be listed."
"Fourthly, however, the ET's role is arbitral not inquisitorial or investigative. It must perform its functions impartially, fairly and justly, in accordance with the overriding objective, the law, and the evidence in the case. It may consider it appropriate to explore the scope of a party's case by way of clarification. That may, in particular, be considered appropriate in the case of an unrepresented party. Whether to do so is however a matter of judgment and discretion which will rarely qualify as an error of law such that the EAT can interfere. The ET has no general duty to take pro-active steps to prompt some expansion or modification of the case advanced by a party where that might be to their advantage. These propositions emerge clearly from a series of decisions of this court and the EAT."
"However, all that said, the starting point is that the parties must set out the essence of their respective cases on paper in respectively the ET1 and the answer to it. If it were not so, then there would be no obvious principle by which reference to any further document (witness statement, or the like) could be restricted. Such restriction is needed to keep litigation within sensible bounds, and to ensure that a degree of informality does not become unbridled licence."
