Sovereignty in the Exercise of the Right to Self-Determination detangles the relationship between a number of principles of international law and the exercise of sovereign power. Jane Hofbauer’s assessment is conducted through an analysis of the different tiers of self-determination, ranging from the right to exercise external self-determination, the right to exercise forms of autonomy as a form of de facto independence, and the right to a type of ‘spatial’ independence, exemplified through the principles of permanent sovereignty over natural resources (PSNR), and free, prior and informed consent (FPIC). The book not only highlights the (intentional) uncertainties within each of these principles, but identifies the (non-discretionary) limits to their normative evolution. It thereby explores to what extent (indigenous) peoples can be designated as sovereign entities.
