The outcome

The tribunal dismissed the claims of unfair dismissal, ruling that the Secretary of State for Justice had acted reasonably throughout.

Key reasons:

  • The employer carried out a thorough investigation, including expert evidence on use of force.
  • The disciplinary process allowed the claimants to challenge evidence and question witnesses.
  • The decision to dismiss was within the range of reasonable responses for a reasonable employer.

No compensation was awarded as the claims failed.

Lessons & takeaways

  • Employers can rely on expert evidence to assess complex conduct issues, such as use of force, even if CCTV is unavailable.
  • A witness changing their account during a hearing does not automatically make the process unfair, as long as the employer considers the change properly.
  • A thorough investigation and fair disciplinary process can protect a dismissal decision from being overturned, even if the employee disagrees with the outcome.
  • Prison officers and other staff in high-risk roles should be aware that use of force incidents will be scrutinised, and initial accounts may be challenged later.

When a witness changes their story

Two prison officers at HMP Belmarsh were dismissed after a physical altercation with a prisoner in January 2022. Both officers initially stated that the prisoner had punched one of them first, justifying their use of force. However, during the disciplinary hearing, a key witness—Senior Officer Churchill—changed her account, saying she could no longer confirm seeing the punch. This shift, combined with expert evidence that the force used was excessive, led the dismissing governor to find the officers guilty of gross misconduct.

The officers argued that the process was unfair, particularly because CCTV footage from outside the cell was not available. But the tribunal noted that the employer had conducted a thorough investigation, including a management enquiry, an expert report on use of force, and a full disciplinary hearing where the officers could question witnesses. The absence of CCTV did not make the process unreasonable, as the employer had other evidence to rely on.

What the employer did right

The tribunal highlighted several aspects of the process that were fair: the officers were suspended on full pay, had union representation, were given the chance to challenge evidence, and had an appeal hearing. The dismissing governor considered all the evidence, including the changed witness account, and gave detailed reasons for the decision. The tribunal concluded that a reasonable employer could have reached the same conclusion.

What this means for similar claims

This case shows that even when key evidence is missing—like CCTV—a dismissal can still be fair if the employer follows a robust process. For employees in high-risk roles like prison officers, it is important to understand that use of force incidents will be closely examined, and initial accounts may be scrutinised. The key lesson for employers is to ensure investigations are thorough and that disciplinary hearings allow employees to respond to all evidence against them.
