Section 15 of the EA 2010 provides:

15 Discrimination arising from disability

(1)

A person (A) discriminates against a disabled person (B) if—

(a)

A treats B unfavourably because of something arising in consequence of B's disability, and

(b)

A cannot show that the treatment is a proportionate means of achieving a legitimate aim.

(2)

Subsection (1) does not apply if A shows that A did not know, and could not reasonably have been expected to know, that B had the disability.

Section 15 is relevant to discrimination in all fields covered by the EA 2010, including employment. It is common ground (see McAuley Catholic High School v C and ors [2003] EWHC 3045 (Admin)) that the Act is to be interpreted in the same way in education cases as in employment cases.

In Pnaiser v NHS England and Coventry City Council [2016] IRLR 170, Simler J (as she then was) held at [31] that the proper approach to be taken to section 15 claims is as follows:-

(a)

A Tribunal must first identify whether there was unfavourable treatment and by whom: in other words, it must ask whether A treated B unfavourably in the respects relied on by B. No question of comparison arises.

(b)

The Tribunal must determine what caused the impugned treatment, or what was the reason for it. The focus at this stage is on the reason in the mind of A. An examination of the conscious or unconscious thought processes of A is likely to be required, just as it is in a direct discrimination case. Again, just as there may be more than one reason or cause for impugned treatment in a direct discrimination context, so too, there may be more than one reason in a section15 case. The ‘something’ that causes the unfavourable treatment need not be the main or sole reason, but must have at least a significant (or more than trivial) influence on the unfavourable treatment, and so amount to an effective reason for or cause of it.

(c)

Motives are irrelevant. The focus of this part of the enquiry is on the reason or cause of the impugned treatment and A's motive in acting as he or she did is simply irrelevant: see Nagarajan v London Regional Transport [1999] IRLR 572. A discriminatory motive is emphatically not (and never has been) a core consideration before any prima facie case of discrimination arises, contrary to Miss Jeram's submission (for example at paragraph 17 of her Skeleton).

(d)

The Tribunal must determine whether the reason/cause (or, if more than one), a reason or cause, is “something arising in consequence of B's disability”. That expression ‘arising in consequence of’ could describe a range of causal links. Having regard to the legislative history of section 15 of the Act (described comprehensively by Elisabeth Laing J in Hall), the statutory purpose which appears from the wording of section 15, namely to provide protection in cases where the consequence or effects of a disability lead to unfavourable treatment, and the availability of a justification defence, the causal link between the something that causes unfavourable treatment and the disability may include more than one link. In other words, more than one relevant consequence of the disability may require consideration, and it will be a question of fact assessed robustly in each case whether something can properly be said to arise in consequence of disability.

(e)

For example, in Land Registry v Houghton UKEAT/0149/14 a bonus payment was refused by A because B had a warning. The warning was given for absence by a different manager. The absence arose from disability. The Tribunal and HHJ Clark in the EAT had no difficulty in concluding that the statutory test was met. However, the more links in the chain there are between the disability and the reason for the impugned treatment, the harder it is likely to be to establish the requisite connection as a matter of fact.

(f)

This stage of the causation test involves an objective question and does not depend on the thought processes of the alleged discriminator.

(g)

Miss Jeram argued that “a subjective approach infects the whole of section 15 ” by virtue of the requirement of knowledge in section 15(2) so that there must be, as she put it, ‘discriminatory motivation’ and the alleged discriminator must know that the ‘something’ that causes the treatment arises in consequence of disability. She relied on paragraphs 26 to 34 of Weerasinghe as supporting this approach, but in my judgment those paragraphs read properly do not support her submission, and indeed paragraph 34 highlights the difference between the two stages — the ‘because of’ stage involving A's explanation for the treatment (and conscious or unconscious reasons for it) and the ‘something arising in consequence’ stage involving consideration of whether (as a matter of fact rather than belief) the ‘something’ was a consequence of the disability.

(h)

Moreover, the statutory language of section 15(2) makes clear (as Miss Jeram accepts) that the knowledge required is of the disability only, and does not extend to a requirement of knowledge that the ‘something’ leading to the unfavourable treatment is a consequence of the disability. Had this been required the statute would have said so. Moreover, the effect of section 15 would be substantially restricted on Miss Jeram's construction, and there would be little or no difference between a direct disability discrimination claim under section 13 and a discrimination arising from disability claim under section 15.

(i)

As Langstaff P held in Weerasinghe, it does not matter precisely in which order these questions are addressed. Depending on the facts, a Tribunal might ask why A treated the claimant in the unfavourable way alleged in order to answer the question whether it was because of “something arising in consequence of the claimant's disability”. Alternatively, it might ask whether the disability has a particular consequence for a claimant that leads to ‘something’ that caused the unfavourable treatment.
