The course is designed both to provide students with a basic knowledge and understanding of the main framework of the public law, also as a premise for the further legal courses that the students will attend in their subsequent career and in order to realize the relevance of the legal dimension in the political systems. After a general introduction to some fundamental concepts of the discipline, the students will be stimulated on two national experiences, one of civil law (the Italian system) and one of common law (the UK system), being asked to deal with first-hand material and case-law, in order to widen their practical knowledge of the subject, too.
