"sometime after12 October 2015 , as a result of the matter outlined above, Mr Lawson suffered from stress and anxiety, which was later diagnosed as an adjustment disorder."
"35. I have considered the Claimant's disability impact statement in some detail. His statement sets out matters first in relation to the period from October 2015 to May 2016 and then in the period from May 2016 to May 2017."
"43. My finding is as at 9-10 April and3 May 2016 the Claimant was not a disabled person. At that time, I find on balance that the symptoms the Claimant describes were a reaction to adverse circumstances, namely the incident on the Hong Kong flight and its ramifications. I have considered that the Claimant was at work flying during this period. I accept that the technical aspects of flying an aircraft are not normal day to day activities, however activities associated with flying an aircraft are, such as communication with colleagues, the ability to concentrate, organise and understand and the perception of risk. The Claimant said that he would not have reported to work if he was unfit. I must balance this against what the Claimant says about the weeks prior to the [simulation assessment]. On balance this reinforces my decision that the Claimant did not have a mental impairment at that time. 44. Even if I had found that the Claimant did have a mental impairment at that time, I would not have found that impairment to be long term as I have found that the symptoms the Claimant described were in the weeks leading up to the [simulation assessment] in April 2016 and at that time there was no indication that those matters would continue for a year as required by the legislation."
"45. I also must find whether the Claimant was disabled as at May 2017 when his employment was terminated. 46. By this time the Claimant had failed the April and May [simulation assessments] and had been notified that his employment was at risk. He was diagnosed with Adjustment Disorder and received treatment as set out above. 47. The Claimant's witness statement describes how he was in this period. He describes being upset that he was referred to a Psychiatrist as 'things had got so bad' and the stigma in the industry towards mental health issues. The Claimant describes feeling paranoid and anxious about his career and how his whole identity was tightly linked with begin a Pilot for the Respondent. He describes his sleep worsening, not being able to get up in the morning, it took him most of the day to get washed and dressed and it being difficult to leave the house. He moved back with his parents who could assist with washing, cooking and so on. He describes only talking to his brother about matters and having difficulty concentrating on anything and dealing with even simple emails which he sent to his brother to check before sending. This was exacerbated by his father passing away in February 2017 and his feeling that he could not support his mother as he would have liked to. He describes heavy drinking. 48. The Claimant was signed off as being able to work in October 2017 and gained alternative employment as a pilot on30 November 2017 . 49. Inevitably the failing of the [simulation assessment] in April/May 2016 and the threat of dismissal had a profound impact on the Claimant and his symptoms worsened. The Claimant had been diagnosed with Adjustment Disorder and I am satisfied that in this period the Claimant had a mental impairment. 50. I am satisfied that sometime in this period the Claimant's mental impairment had a substantial effect on his ability to carry out his normal day to day activities. What he describes in his witness statement shows that his ability to undertake things that most people do on a regular or daily basis was affected. He did not socialise, he did not care for himself in washing or eating, he found it hard to exercise which is something he did regularly in the past. By this time his ability to concentrate and do simple tasks was affected to a substantial extent. 51. I need to decide when the Claimant's mental impairment had a substantial adverse impact on his ability to carry out normal day to day activities in order to decide whether this was long term as at20 May 2017 . I have already referred to the two medical reports which say that the Claimant's stress symptoms were mild or mild to moderate. I accept the Claimant's argument that the comment by Dr Rowland in isolation should be disregarded as he deals regularly with mental illness of a much more serious kind and his definition of mild may be different to other medical practitioners. However, the Occupational Health report of July 2016 also describes the Claimant's condition as being mild to moderate and says he could do office-based work. The conclusion is that at that time, July 2016, the Claimant's mental impairment was not such that he was unable to undertake normal day to day activities. 52. I am satisfied that at some point after this date, the Claimant's impairment had a substantial impact on his ability to carry out normal day to day activities. It is not possible for me to pinpoint that date. However, whatever date it was, it means that as at20 May 2017 the Claimant did not meet the requirement that the impairment had a substantial and long-term effect on his ability to carry out normal day to day activities. 53. I considered whether the Respondent should reasonably have thought that the impairment would last for a year or longer. There is no evidence before me that the Respondent was or reasonably could be aware of this. The Occupational Health report of20 July 2016 states he should be able to return to work following the successful completion of the CBT. There is no indication of any long-term prognosis. This document was in the Respondent's possession. Apart from this document there is no evidence that the Respondent were in receipt of any other medical information indicating a long-term issue."
"14. As for those cases where it is necessary to project forward to determine whether an impairment is long-term (see paragraph 1(b) under the relevant Part of Schedule 1), in SCA Packaging Ltd v Boyle[2009] ICR 1056 HL Baroness Hale (with whom the other Justices of the Supreme Court agreed) clarified that in considering whether something was likely, it must be asked whether it could well happen. The Guidance on Matters to be taken into Account in Determining Questions relating to the Definition of Disability ("the Guidance"), accordingly now states (see paragraph C3) that "
"24. In the present case, the ET was concerned with a material period that spanned less than 12 months. The Respondents had accepted that the Claimant had been suffering physical (fibromyalgia) and mental stress impairments during the material period. The question was, therefore, whether, viewed at that time rather than with the benefit of hindsight, the effects of those impairments (assuming at this stage substantial relevant adverse effects) were likely to last at least 12 months. Moreover, at the Preliminary Hearing, the ET was not concerned with the question whether the Respondents had actual or constructive knowledge of the Claimant's disability, nor was it concerned with a case of likely recurrence. The only issue was whether any substantial effects suffered by the Claimant at the time were likely to last at least 12 months. 25. Consistent with the approach laid down by the EAT in Walker, the existence of a diagnosis of fibromyalgia might have been evidentially relevant to the ET's assessment but the absence of such a diagnosis was not necessarily determinative. In any event, viewed at the relevant time and thus projecting forward, when asking whether it could well happen that the Claimant's impairments would last for at least 12 months, there was a range of relevant evidence before the ET. It is correct that, as the ET recorded, there was no diagnosis of fibromyalgia until very late in the material period and nothing to suggest that various clinicians and therapists seen by the Claimant prior to the diagnosis had stated that they expected her symptoms to be long-term. On the other hand, however, the ET had the Claimant's evidence of the impairments she suffered over this period, corroborated by the medical evidence and by the fact that she was ultimately - although still within the material period - diagnosed as suffering from fibromyalgia, something that seems to have been suspected by her doctor as early as March 2016. It may be that Dr Khan hoped that once she had left the First Respondent's employment, the Claimant could "slowly improve" but that caveat was, strictly speaking, outside the material period. 26. Keeping its focus on the position prior to31 August 2016 , the ET was required to consider whether there was information before it that showed that, viewed at that time, it could well happen that the effects of the Claimant's impairments would last for more than 12 months. The assessment of that possibility was for the ET, but I cannot be satisfied that it approached its task in this regard correctly. First, the ET's reasoning indicates that it focused on the question of diagnosis, rather than impairment, and that it adopted a narrow view rather than looking at the reality of the risk that it "could well happen" on a broader view of the evidence available. More than that, although stating that it had avoided viewing the issues with the benefit of hindsight, that is precisely what the ET did when putting emphasis on Dr Khan's prognosis post-dating the material period (i.e. as to the possible improvement in the Claimant's symptoms after she had left the First Respondent's employment). In the circumstances, I consider the Claimant is correct in her challenge to this finding. I, therefore, allow the appeal on this first ground."
"I must confess with great respect to some difficulty with the "plainly and unarguably right" test elaborated in Dobie . It is not the task of the EAT to decide what result is "right" on the merits. That decision is for the ET, the industrial jury. The EAT's function is (and is only) to see that the ET's decisions are lawfully made. If therefore the EAT detects a legal error by the ET, it must send the case back unless (a) it concludes that the error cannot have affected the result, for in that case the error will have been immaterial and the result as lawful as if it had not been made; or (b) without the error the result would have been different, but the EAT is able to conclude what it must have been. In neither case is the EAT to make any factual assessment for itself, nor make any judgment of its own as to the merits of the case; the result must flow from findings made by the ET, supplemented (if at all) only by undisputed or indisputable facts. Otherwise, there must be a remittal."
