This article offers a systematic analysis of the plenary Chamber of the French Cour de Cassation's final decision in the Baby Loup case which held that a private nursery had acted lawfully when requiring an employee to remove her jilbab at work, in accordance with the religious neutrality requirements of the nursery's policy. The article examines the decision in light of ECHR and French domestic legal requirements. First, it is argued that laïcité—rightly held to be irrelevant—still unduly taints the reasoning. As a result, proportionality and anti-discrimination provisions are not properly applied. Secondly, the decision is compared and contrasted with recent ECtHR cases, notably Eweida and Others v UK. It is argued that a Baby Loup-type restriction does not meet ECHR standards. Additionally the margin of appreciation, used by the ECtHR to save the French ban on the full-covering of the face in the SAS case, should not, as will be demonstrated, come into play in a Baby Loup context.
