"6. It has been repeatedly stated in the authorities that criteria used for selection must be objective or at any rate capable of objective assessment. In the IDS handbook 42 published in December 1988 the following statements appear; on page 190 "(criteria) must be capable of objective assessment i.e. capable of some sort of independent assessment using the reasonable employer test. Subjective criteria will generally be unreasonable as the case below illustrates"; on page 192 (under the hearing "Individual Ability and Performance"). "It is a reasonable aim to try to retain a balanced workforce. Hence an individual's skill and knowledge are reasonable considerations provided they are assessed objectively". The same statements appear in a later edition of the IDS handbook dated September 1993 on pages 210 and 211. The case from which these statements are ultimately derived is Williams -v- Compair Maxim1982 IRLR 83 . These statements in successive editions of the IDS handbook have not as far as we are aware ever been doubted. The tribunal asked Mr Dean, who appeared for the respondents to produce over the short adjournment any authorities of which he was aware establishing that it was acceptable for employers to use subjective criteria and/or apply criteria subjectively. This request was totally ignored."
"In the circumstances the tribunal has no hesitation in deciding that Mr Warburton's dismissal was unfair."
"The two lay members of this appeal tribunal hold the view that it would be impossible to lay down detailed procedures which all reasonable employer would follow in all circumstances: the fair conduct of dismissals for redundancy must depend on the circumstances of each case. But in their experience, there is a generally accepted view in industrial relations that, in cases where the employees are represented by an independent union recognised by the employer, reasonable employers will seek to act in accordance with the following principles:"
" The lay members stress that not all these factors are present in every case since circumstances may prevent one or more of them being given effect to. But the lay members would expect these principles to be departed from only where some good reason is shown to justify such departure."
"The tribunal appeared to have applied the right test by saying they [ the Williams principles ] are mere guidelines, but are wrong to hold that the finding that the procedure was unfair in itself necessarily leads to the conclusion that it is unfair under section 57(3)."
