'Stacking' in this book is not just a notion to explore an empirical situation of disorder. Its main value as an analytical concept is that it clarifies how 'plurality' of norms come into being, as well as the structure of this plurality and the elements it consists of. In the complex of laws and norms, divergent legal concepts and interpretations and re-interpretations of these concepts are assembled and serve as a basis for rights and claims to land, whereby in time, new elements and interpretations are continuously added to the complex while other elements disappear from it. Sometimes one element is more important, and sometimes another. Furthermore, the notion of 'stacking' makes clear that the constellation of norms surrounding land rights is constantly changing; it is a never-ending process. This process does not create a disordered pluralism, an untidy and random heap of norms without any sense or logic, but it leads to a certain stacked structure in which the separate elements have not merged into a kind of fluid constellation. Its stacked character implies that social actors may be able to recognise the different elements and to use them for their own purposes. They distinguish between different elements and exchange them, reinterpret them or discard them.
