Strike-out hearing
The tribunal heard the respondent's application to strike out the s103A claim and decided to strike it out.
The legal issue
The tribunal had to decide whether the claimant's automatic unfair dismissal claim under section 103A of the Employment Rights Act 1996 had a reasonable prospect of success. This required showing that the principal reason for dismissal was that they had made a protected disclosure.
The outcome
The tribunal struck out the claim, finding it had no reasonable prospect of success. The final hearing was cancelled.
The key reason was that the claimant could not establish a sufficient connection between their alleged protected disclosures and their dismissal. The respondent's application to strike out was granted.
No compensation was awarded as the claim was struck out.
Lessons & takeaways
- To succeed in a whistleblowing unfair dismissal claim, you must show that the protected disclosure was the principal reason for your dismissal, not just one factor among many.
- Tribunals will strike out claims that have no reasonable prospect of success early, saving time and costs for both parties.
- If you are a contract worker, ensure you understand your employment status and the legal protections available to you before bringing a claim.
- Keep clear records of any protected disclosures and the employer's response, as this evidence is crucial to proving your case.
This case shows the high bar claimants face when bringing whistleblowing unfair dismissal claims. The contract worker alleged they were dismissed for making protected disclosures about a manager's conduct, but the tribunal found their claim had no reasonable prospect of success.
What went wrong for the claimant?
The key issue was that the worker could not demonstrate a sufficient link between their disclosures and their dismissal. The tribunal concluded that even if the disclosures were protected, there was no evidence that they were the principal reason for the dismissal. This is a common stumbling block in whistleblowing cases: claimants must prove causation, not just that a disclosure was made.
What the respondent did right
ICON Clinical Research Limited applied to strike out the claim at an early stage, arguing it had no reasonable prospect of success. The tribunal agreed, cancelling the final hearing. This approach saved significant time and costs for the respondent.
Why this matters for similar claims
This decision reinforces that tribunals will not allow weak whistleblowing claims to proceed to a full hearing. Claimants must have solid evidence linking their disclosure to their dismissal. The case also highlights the importance of understanding employment status — contract workers may have different protections than employees. For anyone considering a whistleblowing claim, seeking early legal advice and gathering strong evidence is essential.
