Claimant v London Borough of Hounslow
Outcome
Individual claims
The claims of automatically unfair dismissal in Claims 2, 3 and 4 were struck out on the basis of res judicata / cause of action estoppel. Claim 1 had previously been struck out by EJ Fowell for failure to pay a deposit order. The tribunal held that the automatically unfair dismissal complaints in the subsequent claims were covered by the res judicata principle and were therefore an abuse of process.
Allegations c, d and e of protected disclosure detriment were struck out. Allegation c (the decision to dismiss) and d (the dismissal itself pleaded as a detriment) were held to fall within s.47B(2) ERA and/or were subject to cause of action estoppel. Allegation e (manner of dismissal) was held to be in reality a complaint about the dismissal itself and therefore subject to the same estoppel. Allegations a, b and f were not struck out and remain live.
Three of the six alleged detriments (c, d, e) were struck out as either falling foul of s.47B(2) or being subject to res judicata. The remaining detriment allegations (a: dismissive and belittling treatment; b: exclusion from meetings; and f: failure to follow appeal procedure) were not struck out and the respondent's application in respect of those allegations failed.
The respondent's application to strike out the ordinary unfair dismissal claim (Claim 5) failed. The tribunal held there was a significant level of factual dispute, particularly regarding the reliability of the evidence that the claimant had been working from Vietnam, the claimant's technical arguments, and the appeal process. The tribunal concluded the claim had more than a fanciful prospect of success and did not meet the test for strike out or deposit order.
Facts
The claimant was dismissed on 16 May 2024 for alleged unauthorised working from Vietnam, a high-risk country. He brought five separate claims against the respondent council and two individuals between May and July 2024. The first claim, for automatically unfair dismissal and interim relief, was struck out by EJ Fowell after the claimant failed to pay a £10 deposit order by the specified date. The claimant had applied for reconsideration but did not pay the deposit. The respondent applied to strike out the subsequent claims on res judicata grounds and argued the unfair dismissal claim had no reasonable prospect of success.
Decision
The tribunal struck out all automatically unfair dismissal claims and three of six protected disclosure detriment allegations on grounds of res judicata / cause of action estoppel, finding they were covered by the earlier strike-out judgment. Three detriment allegations (dismissive treatment, exclusion from meetings, and failure to follow appeal procedure) survived, as did the ordinary unfair dismissal claim. The tribunal held there were sufficient factual disputes about the dismissal process and evidence to allow the unfair dismissal claim to proceed to a full hearing.
Practical note
A deposit order that is not paid by the specified date leads to mandatory strike-out, creating an estoppel that prevents relitigation of the same cause of action even where no reasoned merits decision was made, but claims exempt from early conciliation requirements (like interim relief applications) do not create an estoppel preventing later claims that could not have been brought at the same time.
