It exhaustively covers the global response to terrorism in transnational criminal law, the international law on the use of force, international humanitarian law, international human rights law, the law of State responsibility, the United Nations Security Council, General Assembly, UN specialised bodies, and regional organisations. It also addresses special legal issues in dealing with terrorism such as gender, religion, victims of terrorism, weapons of mass destruction, and customary law.

Chapter 2: Terrorism and customary international

Kai Ambos and Anina Timmermann


The following chapter attempts to analyse if terrorism has become a crime under customary international law. We start with a brief look at the minimum requirements of customary law in general and its particularities regarding criminal law. It will be shown that there are several general concerns regarding the creation of criminal provision by custom, especially because of the inevitable vagueness of unwritten law and the ensuing conflict with the principle of legality (nullum crimen sine lege). We will then explain the different categories of international(ized) crimes distinguishing between the core and the treaty-based crimes. The second section will focus on the crime of terrorism. We will inquire into the relationship between terrorism and international criminal law and how it is affected by custom. Other international law aspects, intimately related to the current terrorism debate, such as state responsibility, the duty to prevent terrorism, state territory being used by terrorists, and the lawfulness of the use of force against terrorism, will not be treated. The gist of the issue is whether terrorism fulfils the decisive criteria of a true international crime, thereby making it possible to prosecute perpetrators globally, notwithstanding their protection by states. We will, on the basis of several international treaties, suggest a possible customary law definition of terrorism.
