"…if a demand factor was utilised [a demand factor is a factor relevant to the evaluation part of the exercise] then there had to be something additional in order to justify a defence under section 1 (3)."
"By Community law the defence which is open to the employer is that such discrimination as existed was objectively justified. There is no limitation to those factors and reasons upon which that defence may be based and we see no reason why the factors should be limited in the defence under section 1 (3). The essential is that it should be based on a material factor which is genuine and the variation is genuinely due to that material factor which is not a difference of sex. The argument could also be supported by the difference in the wording in section 1 (3) (a) and section 1 (3) (b). In (a) there is a reference to "difference between the woman's case and the man's" – this indicates a direct comparison in the demands, and in paragraph (b) the words used are "may be" such a material difference and therefore indicates that it goes outside the immediate comparison between the woman's case and the man's case which is the distinction or the difference in comparison in demands."
