In many contexts, States fail to establish and enforce a clear legal hierarchy based on the guarantees of equality and non-discrimination set forth in international human rights law and national legislation, thus helping to maintain patriarchal modes of organization and behaviours. Even when the law is independent of any religious source, it may be strongly influenced by culture, deriving from dominant ideologies linked to religion, traditional attitudes and social norms. Some States adopt national laws and regulations that restrict the rights, power and mobility of women on the basis of essentialist points of view belonging to a particular culture or religion. Conservative religious extremist movements impose strict modesty codes in order to subjugate women and girls in the name of religion, particularly in situations of political transition or conflict. For example, some branches of Islam have reintroduced forced and/or early marriage and some branches of Christianity prevent women from having access to therapeutic abortion. Religious extremism limits women's rights, including their right to health and economic activity, and they are generally subject to harsh sanctions for crimes committed against the patriarchy, such as adultery. At the international level, many States justify their reservations to articles of several human rights conventions, including the Convention on the Elimination of All Forms of Discrimination against Women, in the name of preserving their cultures and religions. Human Rights Council resolutions 16/3 on promoting human rights and fundamental freedoms through a better understanding of traditional values of humankind and 26/11 on the protection of the family threaten to undermine international achievements in the field of human rights in the name of cultural and religious diversity.
