The author of this volume goes back to the meaning of the term ""source"" and analyzes in detail the various sources of international law. A critical analysis of other representative views is given as the book explores solutions to problems presented.
A systematic explanation of recent pronouncements of international courts and tribunals with regard to customary law is also given, as well as a specific examination of solutions prescribed in the 1969 Vienna Convention on the Law of Treaties.
