This volume is the first comprehensive commentary on the Convention on the Elimination of All Forms of Discrimination against Women and its Optional Protocol. The Convention is a key international human rights instrument and the only one exclusively addressed to women. It has been described as the United Nations' 'landmark treaty in the struggle for women's rights'. The Commentary describes the application of the Convention through the work of its monitoring body, the Committee on the Elimination of Discrimination against Women. It comprises detailed analyses of the Preamble and each article of the Convention and of the Optional Protocol. It also includes a separate chapter on the cross-cutting substantive issue of violence against women. The sources relied on are the treaty language and the general recommendations, concluding observations and case law under the Optional Protocol, through which the Committee has interpreted and applied the Convention. Each chapter is self-contained but the Commentary is conceived of as an integral whole. The book also includes an Introduction which provides an overview of the Convention and its embedding in the international law of human rights.
