Peace and Security
Use of Force
Current Issues on the Prohibition of Use of Force in International Relations
The rule on the prohibition of the use of force in international relations, which has become a peremptory norm of international law, is still valid, notwithstanding the doubts raised by a handful of authors. Instead, it is the exceptions to the prohibition that are a matter of controversy. Article 51 of the UN Charter is still the object of contending interpretations and the doctrine is divided on the existence of other permissible exceptions to the prohibition on use of force. The case-law of the International Court of Justice now includes a number of judgments and advisory opinions which may help the interpreter to find the correct solution.
