The Respondent had carried out a job evaluation exercise in co-operation with the trade unions. The plaintiff and comparators had been rated as equivalent in the course of this exercise but the employer had failed to implement the scheme because of Government pay policy. The House was asked whether the claimant could regard herself for the purposes of the Act as rated as equivalent with her comparator when the scheme had not been implemented.
Held: She could. once the job evaluation study had been agreed so that it was possible to use it as a basis for comparing jobs, then it could be relied upon even although it had not in fact been implemented. A job evaluation study may not be enforced until it has been completed: ‘It is not the stage of implementing the study by using it as the basis of the payment of remuneration which makes the study complete: it is the stage at which it is accepted as a study. It is perfectly possible to accept the validity of a study at a stage substantially before it is implemented.’
Lord Russell stated: ‘In summary, therefore, I am of the opinion that the words in dispute cannot have the result extended for by the employers. We are offered a number of dictionary substitutes for ‘determine’ none of which appeal to me. The best that I can do is to take the phrase as an indication that the very outcome of the equivalent job rating is to show the term to be less favourable. The next best I can do is to echo the words of Lord Bramwell in Bank of England v Vagliano Bros  AC 107 at 139: ‘This beats me’, and jettison the words in dispute as making no contribution to the manifest intention of Parliament.’
