Why threatening claimants with costs may be a dying stratagem

The Employment Appeal Tribunal (EAT) allowed the appeal and set aside the dismissal judgement, ruling that a claimant’s correspondence must be clear, unequivocal, and unambiguous to constitute a valid withdrawal of proceedings.

Facts:

The case originated from a claim filed by the claimant in December 2023 against Healthwatch Stockport Ltd. and Stockport Metropolitan Borough Council. In his initial claim, he alleged unfair dismissal, sexual and racial discrimination, and detriment resulting from whistleblowing, specifically regarding his treatment after making protected disclosures. While the claim against the council was withdrawn and dismissed early on, the claim against Healthwatch Stockport Ltd. proceeded.

The respondent served its response in March 2024, arguing that the claimant was a volunteer and that his claims were vexatious, subsequently threatening to apply for a strike-out order and a costs award in the range of £2,500 to £3,000. Due to his wife’s passing, the case was postponed.

The crux of the conflict arose on 31 May 2024, at which point the claimant sent two emails to the Employment Tribunal (ET). In his first email, he expressed extreme concern over the respondent’s costs warning and stated that, in the absence of certainty regarding the maximum costs the ET might award, he wished to withdraw his claim. He specifically asked the ET to advise him on the potential maximum so he could give “further consideration” to withdrawing. Later that afternoon, after receiving no reply and failing to reach the ET by phone, he sent a second email. In this message, he stated that he wished to confirm the withdrawal of his claim unless the Tribunal would agree not to apply a costs order against him for the period discussed.

However, the ET’s internal processing of these emails was disorganised. On 4 June, Employment Judge Batten, having seen only the first email, correctly identified it as a potential tactical withdrawal and invited the claimant to clarify his position within 14 days. However, on 9 June, a staff member who had seen the second email, but not the first, sent a letter treating the claim as having been fully withdrawn and cancelled the upcoming hearing. Unaware of the 9 June letter, the claimant responded to the 4 June invitation on 10 June, stating explicitly that he wished to continue with his claim.

Despite this clarification, the ET issued a letter on 20 June under the instruction of Employment Judge Butler, asserting that the claim had been unambiguously withdrawn and could not be resurrected. On 26 June, a Legal Officer signed a formal judgement dismissing the proceedings.

Decision:

The EAT ruled in favour of the claimant, finding that the original ET had committed an error of law. Judge James Tayler determined that the claimant’s emails of 31 May 2024 did not meet the legal threshold of being “clear, unequivocal, and unambiguous” as required under Rule 51. Because the claimant had made his intent to withdraw conditional upon receiving advice or guarantees regarding potential costs—which he never received—the communication was considered equivocal.

The Judge reasoned that a self-represented party in a state of distress, reacting to a costs warning from a respondent, should be treated with a high degree of care. In such a context, the ET should have ensured that the claimant fully understood the consequences of his actions before moving to dismiss the case. Ultimately, because the correspondence remained conditional and “equivocal” on a proper reading, the EAT determined that the claim had never legally come to an end, rendering the dismissal judgement an error of law.

Implications:

The most significant implication is the reinforcement of the “clear, unequivocal, and unambiguous” rule. The EAT has made it clear that if a claimant’s communication contains any “ifs,” “buts,” or “unlesses,” then the Tribunal should not treat it as a final withdrawal. For employers and respondents, this means they cannot immediately rely on a frustrated or conditional email from a claimant as a “get out of jail free” card. They must wait for a formal, unconditional statement or a judicial dismissal judgement before assuming that the risk of litigation has vanished.

The case highlights the Tribunal’s overarching duty to consider the “human context”. This implies that, in future cases, Judges are expected to be more interventionist when an unrepresented party suggests they want to drop a claim due to fear or pressure rather than through a genuine desire to end the pursuit of justice.

This case highlights the prevalent tactic whereby respondents send “warning letters” over potential costs so as to pressure claimants into dropping ‘weak claims’. While these letters are legally valid and often necessary, this judgement suggests that, if a claimant reacts to such a letter with a panicked or conditional withdrawal, then a Tribunal should view it as a “tactical” response rather than as a “final” decision. In this way, respondents may be less inclined to use the threat of costs to trigger an automatic procedural win without the merits of the case being heard.
