The PhD in Public Law is divided into five curricula: Constitutional law and general public law; Administrative law; Criminal law and procedure; International and European Union law and Law and Economics. The curriculum in Constitutional Law and General Public Law studies the classic themes of the two disciplines, as they were defined by the Italian and European legal doctrine. Topics that refer to general, sectoral, state, supranational legal systems; to the sources of law; fundamental rights and legal situations, with reference also to multilevel protection systems in Europe; the dynamics of territorial decentralization; constitutional guarantees and constitutional justice; government structures, with reference to the relations between the supreme state bodies, local authorities and institutions of the European Union. The one in Administrative Law examines the transformation processes relating to the organization and functioning of public administrations and the problems relating to the principle of legality and judicial protection against acts of the public administration. The research scope extends from the study of international administrations, and in particular to its coordination with the national administration, to the analysis of individual sector issues such as food safety, environmental protection and competition. The one in Criminal Law and Procedure proposes a didactic-training offer in a dimension attentive to the interdisciplinary framework of criminal sciences, with the aim of stimulating the doctoral students to a greater openness of their research, which takes into account the reciprocal interactions and influences with other related disciplines, such as penitentiary law, criminology, forensic medicine and forensic psychology. The curriculum in Law and Economics promotes interdisciplinary, legal and economic research activity, in order to improve the understanding of the reasons and effects of regulatory intervention, of the choices related to institutional structures and of the problems related to the enforcement of legal regulations. . The law therefore appears as an object of study, characterized by a set of behavioral incentives / disincentives, to be analyzed and studied through the use of economic tools. The one in International and European Union law intends to offer advanced training in the field of transnational legal phenomena and relations governed by international law and European integration law. PhD students will have to conduct seminars and thematic debates in order to develop analytical and critical skills; activities that will be carried out in constant interaction with the other curricula in order to allow the development of methodological perspectives of an interdisciplinary nature.
