This year’s ‘simulation exercise’, an annual activity for students enrolled in the MAS in International Humanitarian Law at the Geneva Academy, took place at the Palais des Nations, the European headquarters of the United Nations in Geneva. Helped by interpreters from ETI (see below), the Geneva Academy students were asked to advise the United Nations Secretary-General, a role played by Professor Nicolas Michel, on the arrest warrant issued by the International Criminal Court against President Al-Bashir of Sudan. In the context of a Policy Committee, students played the roles of high-level civil servants of the United Nations (UNHCR, OCHA, etc.), State representatives (from the five permanent members of the Security Council), and representatives from both regional and non-governmental organisations (ICTJ, Human Rights Watch, etc.). At the end of the day, after difficult discussions and negotiations, students put forward proposals for a draft of a statement by the Secretary-General, in the hypothetical case that he would be invited to participate in a debate in the Security Council about the consequences of the arrest warrant for international peace and security.
