Case law
Mr I Wilson v The Pensions Regulator

If your employer never showed you the evidence, that alone can make your dismissal unfair.

The ruling

Whistleblowing claim failed, but unfair dismissal claim succeeded: evidence was withheld and never put to him.”

A genuine belief that you did something wrong is not enough to justify dismissal. Your employer needs reasonable grounds too, and you need to see the evidence.

  • Ask, in writing, to see any evidence, log, or report your employer is relying on before it makes a disciplinary decision.
  • If your employer's own procedure promises you copies of interview notes or evidence, that promise is legally enforceable.
  • If you think your employer withheld or never properly checked key evidence before dismissing you, get advice now. Unfair dismissal claims must reach a tribunal within three months less one day of your dismissal.

The situation

The Pensions Regulator dismissed a long-serving financial analyst for allegedly printing sensitive information and taking it home, and for accessing case files without permission. The manager who raised the concern relied on a printed log that did not clearly show which documents were actually sensitive. Legal advice on how to read the relevant policy had been obtained internally, but nobody showed it to the person who made the final decision to dismiss him.

What the tribunal found

The tribunal rejected his argument that he had really been dismissed for raising concerns years earlier. His belief that those concerns showed wrongdoing was not one an objective bystander would call reasonable, so the whistleblowing claim failed.

Ordinary unfair dismissal claims turn on section 98 of the Employment Rights Act 1996. The test asks whether the decision fell within the band of reasonable responses open to an employer, based on grounds that were actually reasonable. That claim succeeded, even though the whistleblowing claim did not. The decision-maker had no reasonable grounds for believing he had taken sensitive documents home. The print log did not reliably show what was sensitive and what was not, and the relevant legal advice never reached him.

The investigation itself was unfair too. The regulator's own policy required disclosure of interview notes from key witnesses. It withheld them anyway, and used the sheer volume of documents he had printed against him without ever giving him a chance to explain it.

A genuine belief that you did something wrong is not enough on its own to justify a disciplinary process or dismissal. Your employer also has to show that belief was reasonably held, based on evidence that actually reached the person who made the decision, not something gathered along the way and left unread.

Your employer has to show you the specific evidence it relies on, whether that's a log, a report, or a pattern spotted in your own activity, and give you a genuine chance to answer it before deciding anything. Skip that step and the process is unfair on its own, even if the underlying allegation later turns out to have some substance.

If you are being investigated, or you've already been dismissed, and you were never shown what was actually held against you, get advice now. Employment Tribunal claims have to be started within three months less one day of your dismissal, extended if you go through Acas early conciliation first. What evidence you did or did not see can make a real difference to that claim.
