'In this book, Dr Fernando Lusa Bordin explores an elusive but fundamental problem: How does general international law apply to international organizations? That leads him to ask, in depth and with great subtlety, the questions what international organizations are from the point of view of international law and how they fit within the international legal system. By analysing the extent to which States and international organizations can be analogised, and how that analogy has served - and can serve - as a basis to extend rules from one category to the other, Dr Bordin provides a theoretically sophisticated and doctrinally informed contribution to our thinking about the sources and subjects of international law.'
