“[…] indicates very strongly that an appellate court should tread very warily when it is being asked to substitute its own impression and judgement for that of the tribunal.” 55. Elias J at para 44 referred further to the judgment of Buxton LJ “He also observed that the Polkey approach - assessing what would have happened had the dismissal been fair - was wholly consistent with the principle of assessing loss flowing from the dismissal on a just and equitable basis, which is the principle underlying section 123. These should be approached as “a matter for the common sense, practical experience and sense of justice of the Employment Tribunal sitting as an industrial jury” (para 14). He also approved the way in which HH Judge McMullen QC had described the process in the EAT in that case (para 26) where the judge had said that the Employment Tribunal’s task was “to construct, from evidence not speculation, a framework which is a working hypothesis about what would have occurred had the [employer] behaved differently and fairly.” 56. We have also had regard to the guidance in Scope v Thornett[2007] ICR 136 and in Leonard v Strathclyde Buses[1998] IRLR 693 , and we quote from the headnote of the latter: “An employment tribunal has to apply the statutory test for assessing a compensatory award as a whole and assess what is just and equitable having regard to the loss so far as attributable to the employer. The extent to which the tribunal can have regard to what followed after dismissal is primarily a matter for it to assess on the particular facts. To introduce principles of foreseeability or remoteness in the technical sense in which those concepts apply in other legal contexts is inconsistent with the discretionary approach which has governed the assessment of unfair dismissal compensation ever since Norton Tool Co (No. 2) v Tewson[1972] IRLR 86 .” 57. We now turn to the authorities on the quantum of compensation for injury to feelings. The leading authority, of course, is Vento , where guidance was given by Mummery LJ. Mummery LJ suggested there should be three bands of compensation. The first band should normally be between£15,000 and£25,000 ;£25,000 has since been updated by the case of Da’Bell to£30,000 . The first band: “65(i) […] should be awarded in the most serious cases, such as where there has been a lengthy campaign of discriminatory harassment on the grounds of sex or race. […] Only in the most exceptional case should an award of compensation for injury to feelings exceed£25,000 .” 58. The middle band, between£5,000 and£15,000 , increased by the Da’Bell case to£18,000 , “should be used for serious cases which do not merit an award in the highest band”; and then, finally, there is a band for less serious cases of between£500 and£5,000 , increased by Da’Bell to£6,000 , “such as cases where the act of discrimination is an isolated or one off occurrence”
