70In that regard it must be noted, first, that, according to the Court’s settled case-law, a national measure which constitutes indirect discrimination because, albeit formulated in neutral terms, it in fact works to the disadvantage of far more women than men, is contrary to Article 4(1) of Directive 79/7, unless that measure is justified by objective factors unrelated to any discrimination on grounds of sex. That will be the case where the measures chosen reflect a legitimate social-policy objective of the Member State whose legislation is at issue, are appropriate to achieve that aim and are necessary in order to do so (see, to that effect, Case C-8/94Laperre [1996] ECR I-273, paragraph 14 and the case-law cited).
