Ms F Mizzi v Denise Griffiths 24 September 2025 — 2025

The claimant applied for interim relief on the basis that she had been dismissed for making a protected disclosure within the meaning of section 43B of the Employment Rights Act 1996. The tribunal considered the claim form, documents, witness statements and submissions, and noted that the underlying unfair dismissal claim under section 103A had not yet been finally determined.

The tribunal applied the interim relief threshold of whether the claimant had a pretty good chance of succeeding at the final hearing. It found clear factual disputes about whether there was a qualifying disclosure, whether it was in the public interest, whether the respondent knew of it at the time of dismissal, and what the reason for dismissal was. On the material before it, the tribunal could not conclude that it was likely the claimant would establish that the reason or principal reason for dismissal was a protected disclosure, so the interim relief application was refused.
