Book excerpt: The right to self-determination has played a crucial role in the process of assisting oppressed people to put an end to colonial domination. Outside of the decolonization context, however, its relevance and application has constantly been challenged and debated. This book examines the role played by self-determination in international law with regard to post-conflict state building. It discusses the question of whether self-determination protects local populations from the intervention of international state-builders in domestic affairs. With a focus on the right as it applies to the people of an independent state, it explores how self-determination concerns that arise in the post-conflict period play out in relation to the reconstruction process. The book analyses the situation in Somalia as a means of drawing out the impact and significance of the legal principle of self-determination in the process of rebuilding post-conflict institutions. In so doing, it seeks to highlight how the relevance of self-determination is often overlooked in this context.
