Belgium's court of cassation had referred the case to the EU's top court for clarification after Samira Achbita was fired when after three years of employment, she began wearing a headscarf to work. She claimed she was being discriminated against on the grounds of her religion. But the company had amended workplace regulations to forbid employees "from wearing any visible signs of their political, philosophical or religious beliefs and/or from engaging in any observance of such beliefs", the court explained in its ruling.
