Timeline
-
Claim presented
The claimant presented a claim form bringing complaints of unfair constructive dismissal, direct discrimination on grounds of pregnancy/maternity, and detriment related to maternity leave.
-
Preliminary hearing
At a hearing before Employment Judge Galbraith Martin, the claimant indicated she wished to amend her claim to include unfair dismissal (not constructive) and automatic unfair dismissal under s.99 ERA 1996. The judge ordered the claimant to provide written amendment by 10 June 2022.
-
Amendment application sent
The claimant sent her written amendment application and further particulars to the respondent and tribunal.
-
Open preliminary hearing
The hearing was held to determine whether the claimant had permission to amend her claim and whether she had complied with a previous direction. The tribunal granted permission to amend.
The legal issue
The tribunal had to decide whether the claimant could amend her claim to add alternative grounds of unfair dismissal by deception and automatic unfair dismissal under s.99 ERA 1996, based on the same facts as her original constructive dismissal and discrimination claims.
The outcome
The tribunal granted the claimant permission to amend her claim.
- The amendments added alternative claims of unfair dismissal by deception and automatic unfair dismissal under s.99 ERA 1996, relying on the same factual allegations already pleaded.
- The respondent opposed, arguing the amendments would require new factual enquiries, but the tribunal disagreed.
- No compensation was awarded at this stage as the hearing was solely about the amendment.
Lessons & takeaways
- If you believe you were tricked into resigning, you may be able to add an alternative claim of unfair dismissal by deception to your constructive dismissal claim.
- Amendments that simply relabel existing facts are more likely to be allowed, even if the respondent objects.
- Act promptly: the claimant here applied to amend within a few months of presenting her original claim.
- Seek legal advice early: having counsel can help frame amendments to show they rely on the same facts.
What this case shows in practice
This case illustrates how employment tribunals handle applications to amend claims, particularly when the underlying facts remain the same. The claimant, an NHS employee, originally brought claims for constructive unfair dismissal, pregnancy/maternity discrimination, and detriment related to maternity leave. She later sought to add alternative claims that she was dismissed by deception and that the dismissal was automatically unfair because it was related to her maternity leave.
The tribunal allowed the amendment, noting that the new claims were based on the same factual allegations already set out in the original claim. The respondent argued that the amendments would require new factual enquiries, but the judge disagreed, finding the changes were minor and did not alter the substance of the case.
What the losing side could have done differently
The respondent could have avoided the dispute by agreeing to the amendment earlier, saving time and costs. The tribunal noted that the amendment was straightforward and did not prejudice the respondent, as the facts were already pleaded. A more cooperative approach might have streamlined the process.
Why this result matters for similar claims
This decision is helpful for employees who realise after filing their claim that they may have additional legal grounds. It confirms that tribunals will generally allow amendments that do not introduce entirely new facts, especially when the application is made promptly. For employers, it highlights that opposing such amendments may be unsuccessful if the underlying facts are unchanged.
