Equality is without any doubt one of the central principles of human rights law. Non-discrimination and equality feature prominently in most of the UN core human rights treaties. But do the human rights treaty bodies understand these principles by and large in a similar way? Do they recognize the same grounds of discrimination? Have largely similar obligations been derived from the principles of equality and non-discrimination? How is gender-based discrimination treated? These and many other questions are addressed in this work. For the first time, all UN Committees‘ decisions on non-discrimination and equality – general comments/recommendations, concluding comments/observations, as well as views/opinions in individual complaints procedures – are comprehensively and comparatively reviewed. Each Committee is thoroughly examined. Also, convergence and divergence, communality and particularity among the Committees is scrutinized. This book may be useful for scholars and practioners who need detailed information on how non-discrimination and equality are interpreted by the UN human rights treaty bodies. Decision-makers in the current reform process of the UN human rights reporting procedure too may benefit from the insights gained in this book.
