Learning about the law is the equivalent of learning a working method or thought model. You must be able to include facts and legal rules in the thought model, which is why the studies focus on rules of law and legal sources, e.g. laws, legal cases and statements. Realising that the law changes and is dependent on social development is also important.
The rules of law have always been the most important aspect of the studies, although due to the rapid changes that are now taking place the focus is shifting towards working methods and thought models.
