ECJ 21 July 2011, case C-104/10 (Patrick Kelly - v - National University of Ireland), Gender discrimination
Article 4(1) of Council Directive 97/80/EC [...] must be interpreted as meaning that it does not entitle an applicant for vocational training, who believes that his application was not accepted because of an infringement of the principle of equal treatment, to information held by the course provider on the qualifications of the other applicants for the course in question, in order that he may establish "facts from which it may be presumed that there has been direct or indirect discrimination" in accordance with that provision.
Nevertheless, it cannot be ruled out that if the defendant refuses to disclose, in the context of establishing such facts, the objective pursued by the Directive could be compromised, depriving Article 4(1) thereof, in particular, of its effectiveness. It is for the national court to ascertain whether that is the case in the main proceedings.
