The 5th edition of Public International Law continues the book's accessible, student-friendly tradition with a writing style that is both conversational and easy to read. Features designed to support learning include highlighted key cases, introductory chapter overviews, and end-of-chapter aides-memoire and recommended further reading. Public International Law is unique in that it is both a textbook and a casebook. The facts of each case and the details of the court or tribunal's decision are succinctly set out, followed by detailed commentary from the author, and, where appropriate, a brief explanation of subsequent events. The book covers all the major areas of public international law, and takes account of new developments relating to the codification of international law by the International Law Commission, State practice, and decisions of international courts and tribunals, in particular those of the International Court of Justice.
