Factual and Procedural Background
The Appellant was employed by the Respondent from 15 April 1995 until her dismissal on capability grounds on 16 August 2024. She worked as a day care worker and officer in charge at a day centre. [1]
In March 2023, the Appellant raised concerns about the handling of a service user during moving and handling procedures and invoked the Respondent’s whistleblowing policy. The Respondent investigated the concerns informally and concluded that no patient-safety issue requiring a formal investigation had been established. [2][3]
The Appellant alleged that her whistleblowing identity had been disclosed without consent, including to her line manager and at a staff meeting. The Tribunal accepted the Respondent’s evidence that disclosure to management had been consented to and found no direct or implicit identification at the meeting. [4]
The Appellant pursued grievances concerning the disclosure, confidentiality, and informal investigation. Separately, she was absent on long-term sick leave, and the Respondent undertook attendance management, considered redeployment and medical evidence, and ultimately dismissed her after concluding that the capability criteria were met. [5][6][7]
The Appellant brought claims for whistleblowing detriment, automatic unfair dismissal, disability discrimination through failure to make reasonable adjustments, and unfair dismissal. The Industrial Tribunal dismissed all claims. [8][9][10]
Legal Issues Presented
- Whether the Tribunal applied the correct statutory and functional test when deciding whether the Appellant was disabled under section 1 of the Disability Discrimination Act 1995. [11][12]
- Whether the Tribunal gave adequate reasons for rejecting the alleged whistleblowing detriments and dismissal claim. [13][14]
- Whether the Tribunal properly addressed the Respondent’s whistleblowing policy and the decision to investigate the disclosure informally rather than formally. [15][16]
- What remedy was appropriate following the Court of Appeal’s conclusion that the Tribunal had erred in its disability analysis. [17][18]
Arguments of the Parties
Appellant’s Arguments
- The Tribunal applied an unduly demanding evidential standard on disability and treated the absence of a formal diagnosis or fuller expert report as effectively decisive, instead of applying the statutory test. [19]
- The Tribunal failed to give adequate reasons for rejecting material alleged detriments arising from the protected disclosure. [20]
- The Tribunal inadequately interpreted the Respondent’s whistleblowing policy by treating it as permitting informal handling without properly addressing its operative provisions. [21]
- The Respondent should have investigated the disclosure through someone suitably independent, because the person involved in gathering statements had a pre-existing conflict with the Appellant. [22][23][24]
Respondent’s Arguments
- The Respondent argued that it had conducted a proportionate informal investigation and that any disclosure of the Appellant’s identity had occurred with her consent. [25]
- It disputed any disclosure to the wider team and any alleged cold-shouldering by colleagues. [25]
- It argued that the Tribunal had fairly determined the attendance-management dismissal and that the dismissal was unrelated to the protected disclosure. [26]
- It submitted that investigation method was essentially a matter for the employer and was not relevant to the Tribunal’s determination. [27]
- It argued that, if ground 1 succeeded, the matter should be remitted to the same Tribunal to consider reasonable adjustments. [28]

Court’s Reasoning and Analysis
The Court confirmed that an appeal under Article 22 of the Industrial Tribunals (Northern Ireland) Order 1996 is confined to points of law. The appellate court does not conduct a rehearing and ordinarily respects factual findings based on witness evidence. [49][29][30][37]
On disability, the statutory test required a physical or mental impairment producing a substantial and long-term adverse effect on normal day-to-day activities. The assessment is functional and legal, not dependent on diagnostic labels or the cause of the impairment. [11][50][39][40][51]
The Court concluded that the Tribunal had nevertheless applied a diagnostic approach. It focused on medical evidence, whether anxiety was clinically diagnosed and sufficiently prolonged, whether the condition was caused by work, and whether the evidence met a personal-injury standard. Those considerations materially misdirected the Tribunal. [52][46][53]
The Court also considered that the Tribunal appeared to require corroboration of the Appellant’s evidence on separate issues after finding her dishonest in relation to the obtaining of clinical records. The Court regarded this as an overarching problem in the treatment of her evidence. [54][55]
The Tribunal had further selected the date when the Respondent first became aware of the Appellant’s medical issues as the starting point for assessing disability. The Court held that this was relevant to the Respondent’s knowledge and reasonable adjustments, but not to whether the Appellant met the statutory definition of disability. [56][57]
On reasons, the Court held that the Tribunal should have addressed each agreed detriment separately. Although most issues were dealt with sufficiently, the Tribunal failed to address the allegation concerning repayment of a salary overpayment. The omission did not, standing alone, justify interfering with the decision. [58][14][59][60]
On the investigation policy, the Court agreed that the choice between formal and informal investigation was principally a matter for the employer. However, it identified concerns about the independence of the person who gathered statements, the pre-existing conflict with the Appellant, whether the alleged investigation method itself constituted a detriment, and the outstanding grievance at the time of dismissal. [27][23][61]
Holding and Implications
The appeal succeeded on ground 1. The Court held that the Tribunal had not properly considered whether the Appellant satisfied the statutory disability test. [12][62]
The Court declined to decide whether the Appellant was disabled. Instead, it ordered that the entire matter be remitted to a differently constituted Tribunal for consideration of all issues afresh, applying the correct statutory test. [28][18]
The Court did not determine grounds 2 and 3 finally, although it recorded concerns regarding the Tribunal’s treatment of evidence, its reasons, and the investigation process. The parties were to be heard on costs. [62][63][64]
The direct effect is that the Tribunal’s dismissal of the claims was set aside for reconsideration by a new panel. The opinion does not state that any broader new precedent was established.
