Through the Millennium Development Goals (MDGs), the international community, and individual states, committed themselves to a major and sustained attack upon world poverty. This book recognises that a considerable number of countries committed to the achievement of MDGs are also involved because of past conflicts or as a result of other types of political transition to constitutional change. In that change, the place of human rights is almost always central. The work argues that such countries can link their MDG commitments to their constitutional development through rights, especially through economic, social and cultural rights. Taking examples of other countries' constitutions, and within a framework of rights, at the international, national and regional levels, the book explains how such rights can be included in national constitutions, and how the courts may respond to claims based on such rights. It also argues that the entirety of a constitution is relevant to the achievement to rights, i.e. that rights are supported not only by 'Bills of Rights'.
