As many real-world networks, legal networks lend themselves to the use of graphs in which nodes represent the decisions and links stand for citations between decisions. This line of research has proved to be efficient for detecting important decisions in legal rulings.
Although useful, this framework does not account for the inherent complexity and hierarchy commonly observed in real data. In the context of legal networks in particular, interactions between decisions take place at various levels, inducing a two-level structure. I propose here to rely on a hybrid version of bipartite graphs, which allows to represent different types of links in multi-level networks. I assess the relevance of this approach by analysing the hybrid structure of the first cases of the International Criminal Court and by confronting it with standard approaches focusing on direct citation processes. Finally, I will show how to extend structural analyses with temporal properties in order to refine the identification of important decisions. I validate the outcomes by providing juridical interpretations of the results.
