While many studies of public administration have focused on decentred forms of governance, they mainly stay within the boundaries of its managerial or coordination aspects. This doctoral dissertation contributes to the literature by moving beyond this, to study both the content and coordination of a decentred governance approach. After studying immigrant integration governance within a range of national and local contexts this dissertation concludes that in a complex and contested policy context, such as immigrant integration, there is a real risk that a decentred governance approach will end up as an evasive strategy due to the perpetuation of policy taboos and dilemmas.
