"at the time had assured him that stress was not a material factor in his illness"
"Mr Murray confirmed that he agreed with the discussions that took place with Ms Young as set out in her witness statement."
"Subject to the provisions of Schedule 1, a person has a disability for the purposes of this Act if he has a physical or mental impairment which has a substantial and long-term adverse effect on his ability to carry out normal day-to-day activities."
"Mental impairment" includes an impairment resulting from or consisting of a mental illness only if the illness is a clinically well-recognised illness."
"(1) It is unlawful for an employer to discriminate against a disabled person - …. (c) by refusing to offer, or deliberately not offering, him employment."
"34 …..the Tribunal was satisfied that the reason Mr Murray was refused the offer of the introductory induction was a concern by the Respondent that Mr Murray might be under stress and might react to it in a violent way, given that the Silvertown CAB was an inner-city Citizens Advice Bureau which attracted vulnerable members of society who could be angry or violent themselves. The type of client could lead to a more stressful situation. We were satisfied that it was for this reason that Ms Young suggested to Mr Murray, which he accepts, that he should commence at a less stressful branch. We are satisfied that this reason related to the previous incident of stabbing someone and not to Mr Murray's paranoid schizophrenia" [our underlining] The Employment Tribunal then had this to say at paragraph 39: "
"(1) For the purposes of this Part, an employer discriminates against a disabled person if - (a) for a reason which relates to the disabled person's disability, he treats him less favourably than he treats or would treat others to whom that reason does not or would not apply; and (b) he cannot show that the treatment in question is justified."
"(2) Regulations may make provisions, for the purposes of this Act - … (b) for conditions of a prescribed description to be treated as not amounting to impairments"
"4 Other conditions not to be treated as amounting to impairments- …. (c) a tendency to physical or sexual abuse of other persons."
"that his psychiatrist at the time had assured him that stress was not a material factor in his illness"
"45……..In the case of a Citizens Advice Bureau in Inner London attended by vulnerable and worried members of society, the issue of whether a potential volunteer had a propensity to inflict violence is material to the circumstances of the particular case and, in the context, substantial. 46 Having taken this into account, it is the unanimous decision of the Tribunal that the Respondent was justified in refusing to offer Mr Murray an introductory induction that might lead to training for a volunteer post"
"The medical report of Dr Ronan McIver indicated that the stabbing incident and tendency to inflict violence was a direct result of the illness of paranoid schizophrenia."
"I have difficulties coping with all areas of personal care, I do not have the motivation to get up, get dressed, move about indoors, etc. I cannot go outdoors without someone with me. I tend to get paranoid at bus stops and on the streets when I am out."
"whether there was material in Dr Cahill's [the employer's medical adviser] hands by the point of decision on which a decision such as she made could properly have been made and as to whether it was a decision open to a reasonable decision-maker on the material before her."
"One does not prove that a reason for a person's treatment is not "material to the circumstances of the particular case and substantial" needed by showing that it was not as material or as substantial as it could have possibly have been."
"Upon a consideration of the wording in s5(3) in context, I conclude that the employment tribunal are confined to considering whether the reason given for the less favourable treatment can properly be described as both material to the circumstances of the particular case and substantial……..In order to rely on s.5(3) it is not enough for the employer to assert that his conduct was reasonable in a general way: he has to establish that the reason given satisfies the statutory criteria ……Where a properly conducted risk assessment provides a reason which is on its face both material and substantial, and is not irrational, the Tribunal cannot substitute its own appraisal. The employment tribunal must consider whether the reason meets the statutory criteria; it does not have the more general power to make its own appraisal of the medical evidence and conclude that the evidence from admittedly competent medical witnesses was incorrect or make its own risk assessment."
"Consideration of the statutory criteria may also involve an assessment of the employer's decision to the extent of considering whether there was evidence on the basis of which a decision could properly be taken. Thus if no risk assessment was made or a decision was taken otherwise than on the basis of appropriate medical evidence or was an irrational decision as being beyond the range of responses open to a reasonable decision-maker ……..the employment tribunal could hold the reason insufficient and the treatment unjustified."
"In both cases, the members of the tribunal might themselves have come to a different conclusion on the evidence, but they must respect the opinion of the employer, in the one case if it is within the range of reasonable responses and in the other if the reason given is material and substantial."
" 'Material' denotes the quality of the connection which must exist between, on the one hand, the employer's reason for discriminating against the employee and, on the other hand, the circumstances of the particular case. …. Mr Griffith-Jones submits that 'material' means 'relevant'. As to this, it is often said that there are degrees of relevance. In this context, I would add to Mr Griffith-Jones' submission the rider that it is not sufficient that the connection is an extenuated one. The use of the word 'material' rather than 'relevant' or 'applicable' indicates to me that there must be a reasonably strong connection between the employer's reason and the circumstances of the individual case. The strength of this connection involves largely a factual enquiry. It ought not to involve an enquiry into medical evidence, since such an enquiry is relevant if at all, to the second limb of section 5(3)……. The second requirement in s.5(3) is that the reason should be 'substantial', This means, in my judgment, that the reason which the employer adopted as his ground for discrimination must carry real weight and thus be of substance. However the word 'substantial' does not mean that the employer must necessarily have reached the best conclusion that could be reached in the light of all known medical science. Employers are not obliged to search for the Holy Grail. It is sufficient is if their conclusion is one which on a critical examination is found to have substance. Thus a reason which on analysis is meretricious would not be a 'substantial' reason. It would fail to meet the test in s.5(3). A tribunal faced with a claim of justification may well find it helpful to proceed by asking the following questions: What was the employee's disability? What was the discrimination by the employer in respect of the employee's disability? What was the employer's reason for treating the employee in this way? Is there a sufficient connection between the employer's reason for discrimination and the circumstances of the particular case (including those of the employer)? Is that reason on examination a substantial reason? The first three of those questions involve pure questions of fact. The fourth and fifth questions, however, involve questions of judgment. The latter questions may involve hearing expert evidence, but the employment tribunal should not conduct an enquiry into what is the best course of action to take in all the circumstances of the case. Nor are the tribunal required to be persuaded themselves. They are not entitled to find that the employer's reason for the discrimination was not justified simply because they take the view that some conclusion, other than that to which the employer came, would have been preferable. Nor can they conclude that justification has not been shown simply because they entertain doubts as to the correctness of the employer's conclusion. If credible arguments exist to support the employer's decision, the employment tribunal may not hold that the reason for the discrimination is not 'substantial'. If, however, the employer's reason is outside the band of responses which a reasonable employer might have adopted, the reason would not be substantial. …….. In short, so far as the second limb of section 5(3) of the 1995 Act is concerned, justification is shown provided that the employer's reason is supportable."
