"8. On13 July 1999 , Personnel Department wrote to Mr King informing him that on 4 August his six months full pay sickness entitlement would come to an end and that from .5 August, based on the decision of ADO Arbuthnot, he would receive only half-pay plus his statutory sick pay. On 19 July, Mr King notified ACO Arbuthnot that he wished to appeal against that decision. The grounds of the appeal were partly financial but also, as Mr King stated in his letter, "most importantly" because he was currently diagnosed as suffering from depression due to work-related problems. On 21 July, ACO Arbuthnot wrote to Mr King to inform him that he had reconsidered the case in the light of the information provided by Mr King but his decision remained the same. However, he said that he would forward Mr King's letter to be considered as an appeal by the Authority. The appeal was to be carried out on the basis of written submissions. 9. In a letter dated5 August 1999 to the Appeal Committee Administrator, Mr King reiterated that his continued absence from work was due to depression brought about as a direct result of extra stresses imposed by work-related problems and that it should therefore be considered as "sickness arising out of authorised duty" and not "normal sickness"
"I did not exercise discretion to leave pay at a higher level because [Mr King] did not qualify as [he] did not suffer from any illness or injury attributable to [his] work." 14. The terms relating to payment during sick-leave are set out in Appendix A of the National Joint Council Conditions of Service ("the Grey Book"). Paragraph 1 (1) states: "
"A member of a brigade on authorised sick leave as a result of an illness or injury arising out of authorised duty shall be entitled to full pay for one year. Thereafter the fire authority may reduce pay to whatever level they consider appropriate in the circumstances subject to a maximum reduction to half-pay for the first six months."
"Where there is a divergence of opinion between the brigade medical adviser and a member's general practitioner (or other medical adviser) over the member's fitness for duty, or the question of whether an illness or injury has arisen out of authorised duty, the fire authority shall-refer the matter to an independent medical referee drawn from those who sit on the boards that consider medical appeals under the Fire-Fighter's Pension Scheme." 15. It was apparent from Mr King's letters to the Fire Authority, the GP's statement on sickness notes and in the GP's letter to the Brigade Medical Adviser dated14 October 1999 , that Mr King's GP was of the opinion that Mr King's depressive illness was work-related. In his medical reports at the relevant times, the Brigade Medical Adviser did not directly deal with this point. However, DCFO Arbuthnot said in his evidence to the Tribunal: "
"30. The evidence given by DCFO Arbuthnot and the reason given in the correspondence for the dismissal of Mr King's appeal against the reduction of his salary to half-pay indicates a misunderstanding of the wording of the Brigade's Sick Leave provisions (documents 333 to 336). DCFO Arbuthnot said that he did hot exercise discretion to leave Mr King's pay at the higher level because he did not qualify on the grounds that he did not suffer from an illness or injury attributable to his work. The Appeal Panel, giving its reason for dismissing Mr King's appeal said: "since the sickness did not arise out of authorised duty, the Members felt unable to uphold your appeal."
"A Member of a Brigade on authorised sick leave shall be entitled to full pay for six months in anyone year period. Thereafter, the fire authority may (the Tribunal's emphasis) reduce pay to whatever level they consider appropriate in the circumstances subject to a maximum reduction to half- pay for the first six months."
"Where there is a divergence of opinion between the brigade medical adviser and a member's general practitioner (or other medical adviser) over the member's fitness for duty, or the question of whether an illness or injury has arisen out of authorised duty, the fire authority shall refer the matter to an independent medical referee drawn from those who sit on the Boards that consider medical appeals under the Fire-fighter's Pension Scheme."
"3. In his evidence, ACO Hughes provided for the Tribunal a summary of those cases occurring since May 1998 where the Fire Authority's discretion had been exercised to extend sick pay at the higher level beyond the six months period. There were apparently 9 cases out of some 400 considered in that period. Mr Hughes divided the nine cases into four categories, namely terminal illness (2 cases), poor quality of life (1 case), self-help, i.e. payment for medical treatment to speed recovery (1 case), and short-term bridging extensions, i.e. where an early return to duty or retirement on ill-health grounds is likely (5 cases). Mr Hughes maintains that each case was considered on its individual merits, and that in the case of Mr King it was clear that there were no special or unusual circumstances that would justify the exercise of the Fire Authority's discretion in his favour. 4. Mr King has argued that the Respondent did not give proper consideration to his personal circumstances, to the nature and seriousness of his illness, to the medical evidence, to its own duty of care, to the appeal from his Member of Parliament that special circumstances existed in his case and to the request by the Fire Brigade's Union in February 2000 to restore his full salary after agreement had been reached to carry out a new investigation into his grievances. 5. A Tribunal may not substitute its own view of how discretion should have been exercised for that of the employer. However, in this case the Tribunal found (paragraph 30 of the substantive Decision) that, contrary to its sick leave provisions, the Fire Authority did not consider the circumstances of Mr King's case when deciding to reduce his pay. No medical evidence was sought by the Fire Authority as to what effect, if any, on Mr King's condition the reduction in pay might have. Indeed, approximately two months after making the initial decision to reduce Mr King's pay, ACO Arbuthnot wrote to the Brigade Medical Advisor: "
"Whilst noting Station Officer King's wife's condition, it is not directly relevant to the salary reduction."
"93. Such an appeal ought only to succeed where an overwhelming case is made out that the employment tribunal reached a decision which no reasonable tribunal, on a proper appreciation of the evidence and the law, would have reached. Even in cases where the Appeal Tribunal has 'grave doubts' about the decision of the Employment Tribunal, it must proceed with 'great care': British Telecommunications plc v Sheridan[1990] IRLR 27 at paragraph 34."
"40. Quite apart from the additional contractual straitjacket for the discretion in this case, the employer's discretion is in any event, as a result of the authorities, not unfettered, as both sides have accepted to be the law in this case. Even a simple discretion whether to award a bonus must not be exercised capriciously ( United Bank Ltd v Akhtar[1989] IRLR 507 EAT, Clark v BET plc[1997] IRLR 348 and Midland Bank plc v McCann5/6/1998 unreported EAT) or without reasonable or sufficient grounds ( White v Reflecting Road Studs Ltd[1991] ICR 733 EAT, and McLory v Post Office[1992] ICR 758 ). I do not consider that either of these definitions of the obligation are entirely apt, when considering whether an employer was in breach of contract in having exercised a discretion which on the face of the contract is unfettered or absolute, or indeed even one which is contractually fettered such as the one here considered. Capriciousness, it seems to me, is not very easy to define: and I have been referred to Harper v National Coal Board[1980] IRLR 260 and Cheall v APEX[1982] IRLR 362 . It can carry with it aspects of arbitrariness or domineeringness, or whimsicality and abstractedness. On the other hand the concept of "without reasonable or sufficient grounds" seems to me to be too low a test. I do not consider it is right that there be simply a contractual obligation on an employer to act reasonably in the exercise of his discretion, which would suggest that the court can simply substitute its own view for that of the employer. My conclusion is that the right test is one of irrationality or perversity (of which caprice or capriciousness would be a good example) i.e. that no reasonable employer would have exercised his discretion in this way. I canvassed this provisional view in the course of argument with both counsel, and neither appeared to dissent, and indeed Mr Temple QC in his closing submissions expressly adopted and used a test of irrationality. Such test of perversity or irrationality is not only one which is simple, or at any rate simpler, to understand and apply, but it is a familiar one, being that regularly applied in the Crown Office or, as it is soon to be, the Administrative Court. In reaching its conclusion, what the court does is thus not to substitute its own view, but to ask the question whether any reasonable employer could have come to such a conclusion. Of course, if and when the court concludes that the employer was in breach of contract, then it will be necessary to reach a conclusion, on the balance of probabilities, as to what would have occurred had the employer complied with its contractual obligations, or, as Timothy Walker J put it in Clark v BET plc , assess, without unrealistic assumptions, what position the employee would have been in had the employer performed its obligation. That will involve the court in assessing the employee's bonus, on the basis of the evidence before it, and thus to that extent putting itself in the position of the employer; but it will only do it if it is first satisfied, on the higher test, not that the employer acted unreasonably, but that no reasonable employer would have reached the conclusion it did acting in accordance with its contractual obligations, and the assessment of the bonus then of course is by way of an award of damages."
