In 2018 the Norwegian government prohibited the wearing clothing that covers the face (essentially meaning niqabs, burqas) - especially concerned about teaching institutions. The most common argument is that:” Norway is an open society where people are used to see each other face to face. This is especially important in kindergartens, teaching institutions and schools” (Jan Tore Sanner - Ministry of Education, Norway) The law passed through the parliament with the support of several parties.
One could argue that this goes against article 18 in the United Nations Universal Declaration Of Human Rights that states that everyone has the right to freedom of thought, conscience and religion: this includes … to manifest their religion or belief in teaching, practice, worship and observance.
