Make them illegal in the entire European Union...
S.A.S. v. France was a case brought for the European Court of Human Rights which ruled that the French ban on face covering did not violate European Convention on Human Rightss (ECHR) provisions on right to privacy or freedom of religion, nor other invoked provisions. Two of the seventeen judges dissented.
Paragraph 2 of article 9 allows limitations on the right to religion if the limitations are prescribed by law and are necessary in a democratic society in the interests of public safety, for the protection of public order, health or morals, or for the protection of the rights and freedoms of others. Specifically, France invoked three grounds for limiting the right to wear burqa: respect for equality between men and women, respect for human dignity and respect for the minimum requirements of life in society.[4]
The court did not find the French governments position that the ban was valid due to gender equality or human dignity concerns, but accepted that Frances claim that a ban was necessary for living together harmoniously was within in law. It underlined that the states had a wide margin of appreciation in cases like this.[4]
