Il principio costituzionale di differenziazione nello sviluppo dei processi di decentramento e di federalismo

Abstract

This paper aims to analyze the principle of differentiation which, under the processes of federalism, identifies a relation of “adaequatio rei et iuris” chosen to allow policies linked on specific local situations. It is worth examining this perspective because the method used to differentiate autonomy, which dates back to the times when Italian Constitution was born, already including special status regions, is currently achieving a growing popularity. In particular, the discussion analyzes the broad doctrinal debate, in both its classical and recent forms, concerning regionalism and federalism, and the theoretical debate on the great principles of equality and autonomy; of uniformity and differentiation. Furthermore, it analyzes in-depth the laws enacted at both state and regional level, the identification of the Best Practices and the constitutional law steps taken in this regard (first part). In the following, the recent experiences of several European countries are taken into account, using the same comparative method: the German, Spanish and Scottish systems of differentiation are analyzed for their many analogies, which can be presented as a step needed for the development of the orientation of the Italian system (second part). The paper then examines the peculiar specialties which have always been in the Italian Constitution in order to verify if, even following the European integration process, the reasons and justifications of the historical specialties still exist (third part). We will show which legislative actions were made with regard to this, as well as the interpretation of the Constitutional Court and the main doctrinal acquisitions achieved during the scientific debate. More specifically, the first part aims to assess, in the first chapter, the constitutional principle of differentiation within the Italian legal system, by considering the theoretical and doctrinal development that accompanied Italian regionalism, and by improving this principle, starting from the of Law no. 142 of the year 1990, up to Bassanini reform. In this context, it is possible to perform an assessment of the third decentralization, which dates over fifteen years ago, by analyzing the tangible situations that have been implemented in the Italian Regions. The discussion then focuses on the origin of Article 116, paragraph III, of the Constitution as changed by Article 2 of the Constitutional Law of October 18, 2001, no. 3, which amended the whole Title V. Methodologically, we decided to illustrate the procedures and limitations with regard to the creation of the differentiation law, as well as the reasons why Article 116, paragraph III, of the Constitution was not implemented, to then analyze the possible areas in which the principle of differentiation could be developed, even in the light of the draft of the Constitutional Law A.C. 2613. The Second part, which is divided into four chapters, depicts the principle of regional differentiation in the European framework. Chapter one specifically focuses on the German federal system, or the so-called Föderalismusreform I – II, which was approved between 2006 and 2009, as a model that is able to effectively combine the flexibility required for continuous development with the rigidity needed to ensure gradual changes in the system. Chapter two covers the evolution of the territorial organization system included in the Spanish Constitution, from 1978 to date, with particular attention to the final result of the differentiated regionalism process by evaluating it both in terms of the doctrinal comments and tangible results. Chapter three focuses on the latest developments concerning Spanish Law and especially on the so-called "Catalan issue" and its statutory events. About this, the research started with an in-depth analysis of the organic law of July 19, 2006, no. 6, before later highlighting the effects of the Constitutional Court ruling (STC 31/2010) of June 28, 2010. Therefore, the composite events that then led to the suspension of the referendum for the independence of Catalonia, as a result of the appeal of the Constitutional Court requested by the Spanish Government, were analyzed. In order to complete the analysis of the differentiation processes, chapter four covers the most recent developments of the nation-building process that occurred in Scotland, whose legislative development and doctrinal issues were studied in-depth. The third part of our research is divided into six chapters and specifically analyzes the only structural differentiation in our country: the one affecting the special status Regions, in order to highlight the main elements of differentiation, both amongst themselves and by comparing them to the other ordinary autonomies. In particular, chapter one contains an in-depth analysis of differentiation within the special status Italian regions. The beginning of the dissertation consists of preparatory works within the Constituent Assembly. After describing the main positions developed in the Italian doctrinal context, some remarks are made on the current status of existence of the special autonomy, even by considering to what extent the financial privileges of some of these special regions can be justified. Chapter two concerns the specialty given to Valle d’Aosta region since a changing process of incremental nature characterizes it. The historical grounds of the specialty are specified by focusing on autonomy in terms of legislation and administration and by describing the structure of the financial autonomy that exists in the region. Chapter three focuses on the autonomy of Friuli Venezia Giulia region by analyzing the specific powers, the exclusive and concurrent regional areas of competence with regard to the different sectors. Chapter four focuses on the specialty of Trentino Alto Adige region, or rather on the autonomous provinces of Trento and Bolzano. With regard to this, an analysis was performed both on the implementation of the legislative decrees of the Statute and on the provincial and regional legislation. In particular, the financial structure, after the Milan Agreement, is discussed in-depth. Chapter five examines the special Statute of Sardegna region at a legislative, administrative and financial level. Furthermore, the constitutional laws that modified the Statute over time (Constitutional Law 1/1972; Law 122/1983; Constitutional Law 1/1986; Constitutional Law 3/1989; Constitutional Law 2/1993; Constitutional Law 2/2001) were carefully analyzed, as well as the actions of the Constitutional Court. Chapter six covers the specialty recognized to region of Sicily by the legislator in terms of exclusive, integrative – concurrent legislations and within the administrative and financial organization. The recent decision no. 255/2014 of the Constitutional Court is also highlighted. The final chapter focuses, even in the light of the comparative analysis carried out, on an overall evaluation of the principle of differentiation by providing observations on the outlook of Italian regionalism.
