Factual and Procedural Background
The Appellant was employed as a legal secretary by the Respondents, a firm of solicitors, from 20th February 2006 until her dismissal with immediate effect on 24th July 2008. In October 2008, she commenced proceedings against the Respondents alleging discrimination based on sex and disability, including victimisation, and unfair dismissal. The Employment Tribunal at London Central, chaired by Employment Judge Auerbach, heard the claim over five days in June and July 2009 and dismissed all claims by judgment dated 25th August 2009. On appeal, the Appellant challenged only the dismissal of her victimisation claims under section 4 of the Sex Discrimination Act 1975 and section 55 of the Disability Discrimination Act 1995, and her claim of unfair dismissal, the latter now based solely on the contention that her dismissal constituted victimisation.
Initially, the Appellant worked one day a week in a job-share arrangement. After the other job-share employee was dismissed in late 2007, it was agreed she would work as a "float secretary" without a job-share. On 17th January 2008, the Appellant submitted a grievance alleging harassment and victimisation, including specific allegations against two partners of the Respondents. It was later established that these incidents did not occur and that her belief in their truth was due to mental illness.
The grievance was investigated by a partner who found the allegations malicious and made in bad faith. The Appellant's grievance appeal was dismissed. Disciplinary proceedings for making false allegations were initiated but suspended when the Appellant went off sick in early February 2008 due to stress-related symptoms, remaining off work until dismissal in July 2008.
During her absence, the Appellant lodged further grievances, mostly alleging discrimination and victimisation, and commenced separate tribunal proceedings relating to earlier incidents. She also had conversations with the Respondents' HR manager, in which she expressed suicidal feelings.
The Respondents obtained medical reports revealing the Appellant's history of mental ill-health, including recurrent depressive illness with psychotic episodes causing paranoid delusions. A consultant psychiatrist concluded her allegations were likely auditory hallucinations linked to her mental illness. Following this, the Respondents ceased disciplinary proceedings but proposed termination of employment due to a breakdown in trust and confidence.
On 23rd July 2008, the Appellant met with the Respondents' Senior Partner to discuss termination. She maintained the truth of her allegations and denied suicidal statements despite evidence to the contrary. The following day, she was dismissed with immediate effect, with the dismissal letter citing the untruthfulness of allegations, her lack of insight into her illness, risk of relapse, and the impracticality of her continued employment due to the breakdown in relationships and the impact on the business.
The Appellant appealed the dismissal, disputing the medical evidence, but the appeal was dismissed. The Tribunal found that the dismissal was based on a breakdown of trust and confidence related to false allegations and mental illness, not on disability or sex discrimination. The Appellant commenced the present proceedings on 21st October 2008 challenging the dismissal.
Legal Issues Presented
- Whether the Employment Tribunal erred in law in its characterization of the reason for the Appellant's dismissal, particularly whether the dismissal constituted victimisation under the Sex Discrimination Act 1975 and the Disability Discrimination Act 1995.
- Whether the Tribunal applied the correct legal test in assessing the comparator for victimisation claims.
- Whether the Tribunal was correct in rejecting the "but-for" causation test as the sole test for victimisation.
- Whether the Tribunal properly applied the burden of proof provisions in discrimination cases.
- Whether the Tribunal erred in its assessment of relevant considerations and evidence regarding the Respondents' motivation.
Arguments of the Parties
Appellant's Arguments
- The prior grievances, especially the grievance concerning the two partners, were factors in the decision to dismiss, and as protected acts, the dismissal constituted unlawful victimisation.
- The Tribunal erred in its construction of the comparator, wrongly including features such as frequency, repetitiveness, falsity, and refusal to accept error in the comparative exercise.
- The Tribunal should have applied a "but-for" causation test to determine victimisation liability.
- The Tribunal failed to properly address the burden of proof and the guidance from relevant case law.
- The Tribunal did not give due weight to the seriousness with which the Respondents treated the discrimination allegations, including non-disclosure of an internal email briefing partners.
Respondents' Arguments
- The reason for dismissal was not the making of complaints of discrimination but the falsity of the allegations, the Appellant's refusal to accept this, and the risk of future disruptive behavior due to mental illness.
- The comparator should be someone who made false allegations of similar gravity but without reference to discrimination, not someone who made no allegations at all.
- The "but-for" test is not the correct legal test for victimisation; the Tribunal should consider the operative or effective reasons for dismissal.
- The burden of proof provisions do not apply where the Tribunal has made positive findings on the evidence regarding motivation.
- The Tribunal properly assessed the motivation for dismissal and gave appropriate weight to all relevant evidence.

Court's Reasoning and Analysis
The Court began by outlining the factual matrix and the Tribunal's findings, particularly that the Appellant's allegations were untrue and caused by mental illness, which led to a breakdown in trust and confidence. The Tribunal found that the dismissal was motivated not by the mere fact of the protected acts (complaints of discrimination), but by features separable from those acts: the falsity of the allegations, the Appellant's refusal to accept their falsity, and the risk of future disruptive conduct linked to her mental illness.
The Court accepted the principle that victimisation claims require examination of the employer's "reason" for the act complained of. It recognized that there can be legitimate distinctions between the protected act itself and separable features or consequences of that act. The Court found that the Tribunal's distinction was legitimate in principle and not contrary to the purpose of anti-victimisation provisions.
Regarding the comparator, the Court held that the Tribunal was entitled to consider a comparator who made false allegations of similar gravity without reference to discrimination, rather than a comparator who made no allegations at all. This approach aligned with established case law and the need to identify the substantive or operative reasons for the dismissal.
The Court rejected the Appellant's submission that the "but-for" test was the correct legal test for victimisation, confirming that the statutory language requires analysis of the substantive reasons for dismissal, not a simplistic causation test. It emphasized the distinction between the employer's motive and the operative cause of the dismissal.
The Court further held that the burden of proof provisions in discrimination legislation do not affect cases where the Tribunal has made clear positive findings on motivation and the legal characterization of those findings. It dismissed the argument that the Tribunal failed to apply these provisions properly.
Finally, the Court rejected the Appellant's contention that the Tribunal failed to give due weight to evidence of the Respondents' motivation, holding that assessment of evidence and weight is a matter for the Tribunal and does not give rise to an error of law absent perversity.
Holding and Implications
The Court DISMISSED the appeal.
The Court upheld the Employment Tribunal's finding that the dismissal was not motivated by the Appellant's protected acts of making discrimination complaints but by the falsity of those complaints, her mental illness, and the associated risk of future disruptive conduct. The Court confirmed the legitimacy of distinguishing between the protected act and separable features or consequences of that act in victimisation claims.
This decision clarifies that victimisation protection does not grant absolute immunity for dismissal arising from features separable from the protected act itself, such as false allegations resulting from mental illness causing management difficulties. The ruling emphasizes careful factual and legal analysis of the employer's operative reasons and rejects simplistic application of the but-for test in victimisation claims. No new precedent was established beyond affirming existing principles and their application to complex factual circumstances.
