This book is a "must read" for anyone interested or researching international law and indigenous peoples.
Thornberry, a member of the Committee on the Elimination of Discrimination (CERD), examines indigenous peoples rights in international human rights treaties and in the practice of the treaty bodies.
He also analyses the (then draft) International Declaration on Indigenous Peoples Rights as well the ILO Conventions (the author qualifies those Conventions as human rights international instruments. However, there are many doubts about that).
The four stars rating are just for one reason: the author should update this book. If it is already quite useful being written around 2003, without the approval of the Declaration and the strong jurisprudence made by the Interamerican Court on Human Rights, the African Comission and the new Poma-Poma v. Peru case by the Committee on Human Rights, imagine if it were updated...
Although technical, I enjoyed reading this book a lot. Good for both begginers on the subject as well as specialists.
