Employment Tribunal Amendments and Lists of Issues: Lessons from London Borough of Ealing & Ors v Peace [2026] EAT 81

Likely to proceed to final hearing; medium-high risk on jurisdiction and pleading, with merits presently uncertain.

The original claim expressly identified disability discrimination and failure to make reasonable adjustments, and the later “Particulars of Claim” are likely to be treated, at least in substantial part, as clarification of an already pleaded complaint rather than a wholly new cause of action.

This is particularly so where the factual theme is consistent: sickness absence, disability, alleged lack of adjustments, suspension, loss of pay and resignation.

A Tribunal is likely to reject the employer’s attempt to exclude core adjustment issues merely because fuller particulars came later, provided they objectively emerge from the ET1 and do not introduce a wholly different factual basis.

However, any entirely fresh adjustment allegations not foreshadowed in the ET1 may still require amendment. Lists of issues summarise existing pleadings and cannot enlarge them without proper amendment.

Likely to proceed, subject to factual proof; medium risk on the employer’s pleading objection.

The ET1 expressly identified constructive unfair dismissal. On the scenario, the later document appears to expand the factual matrix said to amount to repudiatory breach, including failure to adjust, suspension, stopping pay, ignored concerns and ongoing mistreatment, rather than introducing an entirely different dismissal claim.

A Tribunal is therefore likely to include constructive dismissal in the List of Issues and refuse to strike it out merely because the particulars later became more detailed.

The employer may still succeed in limiting any new factual allegations that materially alter the basis of resignation, but not the pleaded head of claim itself.

Pleadings, not later statements, are determinative; yet where the claim already clearly raises a complaint, it should be treated as already brought.

Likely to proceed if the ET1 identified unlawful deductions and the later particulars merely explain when and why pay ceased.

The scenario says the ET1 expressly included unlawful deductions and alleged salary stoppage. That is likely sufficient to keep the wages claim live.

The employer’s argument is stronger only if the later document adds distinct unpaid sums or periods not reasonably encompassed by the original summary.

On the current facts, the Tribunal is more likely than not to allow the issue into the List of Issues because the employer had months of notice and the later pleading appears explanatory rather than transformative.

Likely to proceed if the ET1 pleaded harassment and the later particulars particularise the alleged course of mistreatment.

The pleaded label exists in the original claim, and the later document appears to add detail to “ongoing mistreatment”.

A Tribunal will usually permit clarification of existing harassment allegations, especially in litigant-in-person cases, but should not allow wholly new incidents outside the original factual compass without amendment.

The most likely outcome is that core incidents remain in scope, with any materially new allegations subject to amendment analysis and prejudice balancing.

Moderate risk that at least part proceeds; outcome depends on whether the ET1 objectively pleaded detriment for protected disclosures, not merely general unfair treatment.

The scenario states that the employee alleged concerns raised through a whistleblowing disclosure and that the ET1 identified a wide range of claims.

If detriment or whistleblowing was expressly named, a Tribunal is likely to treat later detail as clarification, not amendment.

If the ET1 only mentioned “concerns” without identifying disclosure-related detriments, the employer’s objection strengthens.

Given the broad pleaded labels and subsequent particulars, the more likely case-management outcome is that the issue proceeds, but with careful trimming to matters objectively arising from the ET1.

Balanced but slightly lower risk: may proceed only if objectively pleaded in the ET1, not merely inferable from later particulars.

Courts distinguish between a claim expressly foreshadowed in the ET1 and one first articulated later.

If “health and safety detriment” was expressly identified in the original claim, the Tribunal is likely to include it despite sparse particulars.

If it was only implicit in factual allegations, the employer has a stronger amendment point.

On the scenario, because this label was said to be in the ET1, the employee has a respectable argument that it was already in play, though clarity issues may narrow it.

Moderate-low risk: may proceed only where the ET1 and later particulars identify a protected act and retaliatory detriment with sufficient coherence.

Simply labelling a claim “victimisation” is often insufficient if the protected act is unclear.

The employer’s objection has force if the later document introduces the first proper articulation of the protected act.

A Tribunal may allow the claim to remain only if the original claim objectively contained the essence of the complaint; otherwise amendment principles and prejudice apply.

Moderate-low risk on these materials.

Although race discrimination was apparently listed in the ET1, the scenario gives no supporting factual narrative linking treatment to race.

A Tribunal is likely to allow only such race allegations as objectively arise from the original claim.

Later particulars adding entirely new discriminatory acts or comparators may well be treated as amendments.

The employer therefore has a stronger procedural objection here than for disability or pay complaints.

Low-moderate risk.

If the contract claim simply mirrors the salary-stoppage allegation or resignation-related notice/pay issues already identified in the ET1, it will probably stay in.

If the later particulars raise separate contractual terms or new losses, amendment may be required.

On the limited facts, the Tribunal is likely to permit only the contract issues plainly linked to the original summary.
