Students must know and understand the basic elements of public international law. To this end, the syllabus logic is distributed across topics (general questions, subjects, sources, application, use of force, global public goods, etc.), through which they can study the fundamentals of the subject. Throughout this syllabus, special attention is paid to the historical and dynamic characteristics of the international legal order, taking into account the specificities of the legal system of Spain. The principal aim of this syllabus is to avoid a formalistic approach towards international law, given that an excessively rigid view would be negative in order to acquire the necessary skills needed by the students in order to fully understand the international legal phenomenon and all its complexities.
