EAT clarifies ‘causation’ test in discrimination arising from disability claims

The EAT holds that the ‘mere’ influence of something related to an employee’s disability is not sufficient to satisfy a discrimination arising from disability claim; the influence has to be ‘significant’.

In Charlesworth v Dransfields Engineering Services Ltd, the EAT upheld an ET’s decision that Charlesworth (C) had not been subjected to unlawful discrimination arising from disability under S.15 of the Equality Act 2010 because C’s absence due to cancer was not the effective or operative cause of his dismissal. C’s absence had enabled the employer to identify the ability to manage without C’s role; therefore, the matter that caused C’s redundancy was the employer’s view that it could do without his job. In rejecting C’s appeal the EAT clarified the ‘causation’ test for S.15 claims.

In Basildon & Thurrock NHS Foundation Trust v Weerasinghe the EAT had held that first, there must be something arising in consequence of the disability; secondly, the unfavourable treatment must be “because of” that “something”. In Hall v Chief Constable of West Yorkshire Police, the EAT described the causal connection as requiring: “… a significant influence on the unfavourable treatment, or a cause which is not the main or the sole cause, but is nonetheless an effective cause of the unfavourable treatment. …”.

The EAT held there is no conflict between the two approaches because in Hall the EAT described the influence that is required as a ‘significant’ one, therefore an argument that a mere influence [here, the absence] is sufficient, could not be accepted.  What caused C’s dismissal was that the employer could manage without him. His absence, albeit part of the context, was not the effective or operative cause of his dismissal.
