The Court of Appeal gave judgment yesterday in an interesting disability discrimination case about mental illness.

Elizabeth McDougall applied for a job at the college in 2005, and got it – subject to medical checks. But when those checks were made, the college withdrew the job offer. Ms. McDougall suffered from persistent delusional disorder and schizo-affective disorder, and had been treated in 2001-2 in hospital under the Mental Health Act, and then in the community by a consultant psychiatrist, whose view was that she was now fully able to return to work. A bit sad, you might think, that the college felt it had to go back on its offer because of Ms. McDougall’s history of mental illness. I agree.

She made a complaint of disability discrimination to the Employment Tribunal, and the legal issue that went to the court of appeal was whether she was disabled within the meaning of the Disability Discrimination Act 1995.

According to section 1, she’d satisfy the definition if she had

a physical or mental impairment which has a substantial and long term adverse effect on [her] ability to carry out normal day-to-day activities.

Of course Ms. McDougall was not arguing that her underlying mental illness stopped her doing her job; her psychiatrist though it wouldn’t. But Schedule 1, paragraph 2(2) provides that

Where an impairment ceases to have a substantial adverse effect on a person’s ability to carry out normal day-to-day activities, it is to be treated as continuing to have that effect if that effect is likely to recur.

If, then, her condition was likely to recur, she’d be disabled, and the dismissal would be discrimination, contrary to section 4(2)(d).

Now, at the time of the dismissal, it would seem to have been reasonable to think the conditions, in their more serious, work-affecting form, wouldn’t be likely to recur: Ms. McDougall was well and fit for work. But as it happened, Ms. McDougall went downhill and the condition did recur, following the dismissal. So when the case reached the Employment Tribunal, how should the tribunal approach the question whether at the time of the alleged discrimination the condition was likely to recur? Would it be right to take into account the knowledge that it did in fact recur? Or should the tribunal ignore that, and consider only the evidence at the time?

The ET ignored the fact of the later recurrence; the Employment Appeal Tribunal reversed that, holding that the later knowledge was relevant; and now the Court of Appeal has reversed the EAT’s ruling, deciding that the later recurrence is not to be taken into account. At the time, Ms. McDougall’s condition was, on the evidence, unlikely to recur – and she was not disabled. The college did not discriminate unlawfully against her.

What I think is strange is how de-coupled the approach of the parties and the Court seems from the social reality here. Of course Ms. McDougall, at the time she got the job, would have hoped her mental health problems were behind her. Had she been asked she would have said, presumably, that they were unlikely to recur. As for the employer, you have to ask why they withdrew their offer: because they feared her mental health problems might well recur, presumably. The reason they dismissed her was obviously because of her mental health problems, and the risk of their recurrence – so it seems very odd indeed that they should be able to argue, now, that at the time they thought it unlikely.

I expect advocates and campaigners on mental illness feel quite gloomy about this case.
