'Equal is not Enough' is the title of a series of conferences that has aimed, over the years, to generate a better understanding of what shapes and reshapes inequalities by inviting and promoting multi-disciplinary insights and reflection. One of the conferences - hosted at Antwerp University in February 2015 - focused on discrimination law. The conveners welcomed papers on the relationship between social policy and discrimination law (or closely related human rights issues), which investigate the tensions and (in) compatibilities between the respective aims and tools of social policy and discrimination law. They were particularly interested in contributions that transcend legal technicalities and reflect on the function of discrimination law as part of a wider social policy in the European Union and its member states. Following a very strict selection procedure conducted by the editors and rigorous peer review, a collection of papers from the conference now appears in this book, Equal is not Enough, which takes its name from the title of the conference. In short, within this volume, the reader will find a selection of high-quality papers presented at this conference, organised by the Flemish Policy Research Centre on Equality Policies (a consortium of the Universities of Antwerp, Brussels, Ghent, Hasselt and Leuven). This publication is aimed at researchers, but it will also be of interest to practitioners of discrimination law who would like to enhance their scientific background.
