ILS – Global law: legal reasoning in International, EU and national law


Admission requirements

Admission to the Masters programme (see the Course and Examination Regulations). This course is only available for the Dutch students, not for the international students enrolled in both programmes.


This course focuses on legal reasoning in the different areas of international and European law. Legal reasoning is a basic legal skill, and there are important differences and similarities in legal reasoning across the different areas of international law, and also when compared to national law. This course also fulfils a practical need, as we know that students struggle in the beginning of the masters to deal with often long and complex judgments from a different legal tradition than the one they are used to. An interaction with national law is also inherent, as national law and legal reasoning will be a logical comparator.

Course objectives

Objectives of the course
The course will contribute to the research skills of students via the weekly assignments and the final paper they will have to write, and which will require them to formulate a research question on the topic of one of the weeks. In addition, the materials and topics will be presented in a research-oriented style, i.e. critically approaching and reflecting on different forms and uses of legal reasoning.
The course centres around the close reading of one seminal case of a different legal order each week. Judgments or advisory opinions would be selected from, for example, the International Court of Justice, the WTO Appellate body, the European Court of Human Rights and the European Court of Justice.

In 5 lectures, students will first be informed about the context and the background of the case, including the different challenges/tensions/interests/views involved, and therefore the choices and dilemma’s facing the judges. Subsequently, the judgment and its consequences will be discussed. In the subsequent working group, students will firstly look at the general structural features of the different case law (for example which sections are legally most relevant). Subsequently, they close read the case, or part of the case, and discuss the different forms of legal reasoning used, also comparing it to the other weeks. Particular attention will be payed to alternative outcomes. One option for the research paper, for example, might be to suggest an alternative outcome based on different methods / applications of legal reasoning.
