There is an ongoing debate in the literature on urban policy networks about governance and, more specifically, the role of public bodies in urban policy implementation networks. This paper focuses on the specific debate in Dutch and Spanish academic and professional circles regarding property rights in land (hereafter property rights) and the need to separate development rights from property rights. The British nationalisation of development rights in 1947 is an important point of reference in these debates. This paper adds to these debates by providing empirical evidence about a land readjustment regulation that public bodies can use to modify the power relationships between public and private parties. This regulation can improve public value capturing by helping public bodies transfer the costs for public infrastructure and affordable housing to developers while capturing part of the enhanced economic value.
