This brilliant book grasps vital issues that have eluded the human rights movement for many years. Casla reconciles social rights, property, and the social function. Everybody committed to the future of human rights will benefit from his exceptional - and accessible - scholarship on the social right to property. -- Paul Hunt, University of Waikato, Aotearoa New Zealand Property rights, and the role of property law in defining these, are critical to collective debates and negotiations over access to the essential resources of social life. Yet, for too long, theories accounting for property rights on the one hand and economic and social rights on the other have run on separate tracks. In this fascinating, bold and deeply thoughtful book, Casla demonstrates why, and shows us how, property and human rights commitments must work together. By engaging with the inner logics of property theory he demonstrates how ideas about property can and should be re-cast in line with social rights, offering a critical new paradigm for human rights scholars interested in resource allocation and for property scholars interested in social justice. -- Lorna Fox OMahony, Essex Law School, UK Understanding the right to property as a human right is central to responding to many of the major challenges posed by privatization, financialization and commodification, and to give real substance to the right to housing. Caslas book weaves together elements from property, human rights, and comparative law, to provide a sophisticated and pioneering analysis of property as a social right. -- Philip Alston, New York University, USA Koldo Casla examines the powerful institution of property, showing how it is a social creation, and everywhere is subject to the requirements of society. This social function of property is becoming a major battleground, with modern States obliged to protect human rights, and social and environmental sustainability. -- Padraic Kenna, University of Galway, Ireland This book proves that, if a human right approach - based on existing norms - is taken seriously when interpreting the contents of the right to property, it has the potential to fight poverty and reduce extreme inequalities in effective ways. Let this interpretation permeate our common sense on voices that can be heard and profits that are (or are not) legitimate. -- Juan Pablo Bohoslavsky, Researcher at the National Scientific and Technical Research Council, Argentina
