The Court of Justice of the European Union (CJEU) has had the opportunity to address the sensitive matter of the wearing of the Islamic headscarf in the workplace in two preliminary rulings. The result of these decisions implies that the wearing of this veil at work is, in general, neither proscribed nor always justified as a legitimate expression of religious beliefs. However, the law studied and applied deals exclusively with discrimination in the workplace on religious grounds. Nonetheless, the Islamic headscarf (...) is only worn by (some) Muslim women (never by men). This article reviews the EU legislation and policy on equality, intersectionality and multiple discrimination to verify that gender mainstreaming does not reach the work of the Court. Only the inclusion of a feminist perspective to the application of justice, with a clear methodology, can guarantee that gender does not disappear in cases of complex discrimination. (shrink)
