The Council of Ministers of the European Union After the Lisbon Treaty

The Treaty of Lisbon has brought remarkable changes and innovations to the European Union. As far as the Council of Ministers of the European Union (“the Council” hereinafter) is concerned, there are two significant innovations: double qualified majority voting and new rotating Presidency scheme, which are considered to make the working of the Council more efficiently, stably and consistently. With the modification relating to other key institutions, the Commission and the European Parliament, and with certain procedures being re-codified, the power of the Council varies accordingly, where the inter-institutional balance counts for more research. As the Council is one of the co-legislatures of the Union, the legislative function of it would be probably influenced, positively or negatively, by the internal innovations and the inter-institutional re-balance. Has the legislative function of the Council been reinforced or not? How could the Council better reach its functional goal designed by the Treaties’ drafter? How to evaluate the Council’s evolution after Lisbon Treaty in the light of European integration? This thesis is attempting to find the answers by analyzing two main internal innovations and inter-institutional re-balance thereinafter.

La protezione dei diritti sociali nell'ordinamento dell'Unione Europea

This study deals with the protection of social rights in Europe and aims to outline the position currently held by these rights in the EU law. The first two chapters provide an overview of the regulatory framework in which the social rights lie, through the reorganisation of international sources. In particular the international instruments of protection of social rights are taken into account, both at the universal level, due to the activity of the United Nations Organisation and of its specialized agency, the International Labour Organization, and at a regional level, related to the activity of the Council of Europe. Finally an analysis of sources concludes with the reconstruction of the stages of the recognition of social rights in the EU. The second chapter describes the path followed by social rights in the EU: it examines the founding Treaties and subsequent amendments, the Charter of Fundamental Social Rights of Workers of 1989 and, in particularly, the Charter of Fundamental Rights of the European Union, the legal status of which was recently treated as the primary law by the Treaty of Lisbon signed in December 2007. The third chapter is, then, focused on the analysis of the substantive aspects of the recognition of the rights made by the EU: it provides a framework of the content and scope of the rights accepted in the Community law by the Charter of Fundamental Rights, which is an important contribution to the location of the social rights among the fundamental and indivisible rights of the person. In the last section of the work, attention is focused on the two profiles of effectiveness and justiciability of social rights, in order to understand the practical implications of the gradual creation of a system of protection of these rights at Community level. Under the first profile, the discussion is focused on the effectiveness in the general context of the mechanisms of implementation of the “second generation” rights, with particular attention to the new instruments and actors of social Europe and the effect of the procedures of soft law. Second part of chapter four, finally, deals with the judicial protection of rights in question. The limits of the jurisprudence of the European Union Court of Justice are more obvious exactly in the field of social rights, due to the gap between social rights and other fundamental rights. While, in fact, the Community Court ensures the maximum level of protection to human rights and fundamental freedoms, social rights are often degraded into mere aspirations of EU institutions and its Member States. That is, the sources in the social field (European Social Charter and Community Charter) represent only the base for interpretation and application of social provisions of secondary legislation, unlike the ECHR, which is considered by the Court part of Community law. Moreover, the Court of Justice is in the middle of the difficult comparison between social values and market rules, of which it considers the need to make a balance: despite hesitancy to recognise the juridical character of social rights, the need of protection of social interests has justified, indeed, certain restrictions to the free movement of goods, freedom to provide services or to Community competition law. The road towards the recognition and the full protection of social rights in the European Union law appears, however, still long and hard, as shown by the recent judgments Laval and Viking, in which the Community court, while enhancing the Nice Charter, has not given priority to fundamental social rights, giving them the role of limits (proportionate and justified) of economic freedoms.

Controlled foreign companies (CFC) e delocalizzazione delle attività economiche nel diritto interno e nell'ordinamento europeo

Le ragioni della delocalizzazione sono molteplici e di differente natura. Si delocalizza, in primo luogo, per ragioni di stampo economico, finanziario eccetera, ma questa spinta naturale alla delocalizzazione è controbilanciata, sul piano strettamente tributario, dall’esigenza di preservare il gettito e da quella di controllare la genuinità della delocalizzazione medesima. E’ dunque sul rapporto tra “spinte delocalizzative” dell’impresa, da un lato, ed esigenze “conservative” del gettito pubblico, dall’altro, che si intende incentrare il presente lavoro. Ciò alla luce del fatto che gli strumenti messi in campo dallo Stato al fine di contrastare la delocalizzazione (più o meno) artificiosa delle attività economiche devono fare i conti con i principi comunitari introdotti con il Trattato di Roma e tratteggiati negli anni dalla giurisprudenza della Corte di Giustizia. In quest’ottica, la disciplina delle CFC costituisce un ottimo punto di partenza per guardare ai fenomeni di produzione transnazionale della ricchezza e agli schemi di ordine normativo preposti alla tassazione di codesta ricchezza. Ed infatti, le norme sulle CFC non fanno altro che omogeneizzare un sistema che, altrimenti, sarebbe lasciato alla libera iniziativa degli uffici fiscali. Tale “normalizzazione”, peraltro, giustifica le esigenze di apertura che sono incanalate nella disciplina degli interpelli disapplicativi. Con specifico riferimento alla normativa CFC, assumono particolare rilievo la libertà di stabilimento ed il principio di proporzionalità anche nella prospettiva del divieto di abuso del diritto. L’analisi dunque verterà sulla normativa CFC italiana con l’intento di comprendere se codesta normativa, nelle sue diverse sfaccettature, possa determinare situazioni di contrasto con i principi comunitari. Ciò anche alla luce delle recenti modifiche introdotte dal legislatore con il d.l. 78/2009 in un quadro normativo sempre più orientato a combattere le delocalizzazioni meramente fittizie.

La circolazione dei servizi in una economia sociale di mercato

Questa ricerca intende esaminare l'impatto della circolazione transfrontaliera dei servizi sul bilanciamento tra regole di mercato e politiche sociali. L'analisi di questa tensione costituisce il punto di partenza per una riflessione più ampia che si propone di comprendere come la conciliazione tra solidarietà e competitività e, più generalmente, tra esigenze di protezione sociale degli Stati membri e tradizionali competenze comunitarie nell'ambito del mercato comune, possa operare nel settore dei servizi. Un mercato comune dei servizi in costante espansione in senso transfrontaliero ha indubbiamente effetti non trascurabili sul piano sociale ed in particolare sul diritto del lavoro consolidatosi nelle tradizioni costituzionali degli Stati membri. La necessità di conciliare solidarietà e competitività alla base del concetto di economia sociale ed il rinnovato accento sulla dimensione sociale dell'Unione accolto nel Trattato di Lisbona dovrebbero promuovere una convivenza armoniosa tra un'integrazione europea di carattere principalmente economico ed i residui spazi di intervento statale a tutela dei mercati nazionali del lavoro. Prima di analizzare cause ed effetti di tale potenziale conflitto nell'ambito del mercato europeo dei servizi risulta necessario fornire un panorama del quadro normativo applicabile agli operatori economici che intendano fornire a titolo temporaneo una prestazione in uno Stato membro diverso da quello di stabilimento. Nell'ambito di tale disamina, dedicata alle fonti conflittuali del diritto europeo applicabili ai prestatori di servizi, individueremo le condizioni che devono rispettare gli operatori per esercitare un'attività in uno Stato membro diverso da quello di origine (Parte I). Potremo quindi illustrare come l'esercizio delle libertà comunitarie di circolazione da parte delle imprese europee abbia fatto emergere le contraddizioni ed i limiti del funzionamento del mercato comune rispetto alla fruizione dei diritti sociali da parte dei lavoratori locali e distaccati (Parte II).

Sviluppo di metodologie di localizzazione nel contesto del Comprehensive Nuclear Test-Ban Treaty

Since the first underground nuclear explosion, carried out in 1958, the analysis of seismic signals generated by these sources has allowed seismologists to refine the travel times of seismic waves through the Earth and to verify the accuracy of the location algorithms (the ground truth for these sources was often known). Long international negotiates have been devoted to limit the proliferation and testing of nuclear weapons. In particular the Treaty for the comprehensive nuclear test ban (CTBT), was opened to signatures in 1996, though, even if it has been signed by 178 States, has not yet entered into force, The Treaty underlines the fundamental role of the seismological observations to verify its compliance, by detecting and locating seismic events, and identifying the nature of their sources. A precise definition of the hypocentral parameters represents the first step to discriminate whether a given seismic event is natural or not. In case that a specific event is retained suspicious by the majority of the State Parties, the Treaty contains provisions for conducting an on-site inspection (OSI) in the area surrounding the epicenter of the event, located through the International Monitoring System (IMS) of the CTBT Organization. An OSI is supposed to include the use of passive seismic techniques in the area of the suspected clandestine underground nuclear test. In fact, high quality seismological systems are thought to be capable to detect and locate very weak aftershocks triggered by underground nuclear explosions in the first days or weeks following the test. This PhD thesis deals with the development of two different seismic location techniques: the first one, known as the double difference joint hypocenter determination (DDJHD) technique, is aimed at locating closely spaced events at a global scale. The locations obtained by this method are characterized by a high relative accuracy, although the absolute location of the whole cluster remains uncertain. We eliminate this problem introducing a priori information: the known location of a selected event. The second technique concerns the reliable estimates of back azimuth and apparent velocity of seismic waves from local events of very low magnitude recorded by a trypartite array at a very local scale. For the two above-mentioned techniques, we have used the crosscorrelation technique among digital waveforms in order to minimize the errors linked with incorrect phase picking. The cross-correlation method relies on the similarity between waveforms of a pair of events at the same station, at the global scale, and on the similarity between waveforms of the same event at two different sensors of the try-partite array, at the local scale. After preliminary tests on the reliability of our location techniques based on simulations, we have applied both methodologies to real seismic events. The DDJHD technique has been applied to a seismic sequence occurred in the Turkey-Iran border region, using the data recorded by the IMS. At the beginning, the algorithm was applied to the differences among the original arrival times of the P phases, so the cross-correlation was not used. We have obtained that the relevant geometrical spreading, noticeable in the standard locations (namely the locations produced by the analysts of the International Data Center (IDC) of the CTBT Organization, assumed as our reference), has been considerably reduced by the application of our technique. This is what we expected, since the methodology has been applied to a sequence of events for which we can suppose a real closeness among the hypocenters, belonging to the same seismic structure. Our results point out the main advantage of this methodology: the systematic errors affecting the arrival times have been removed or at least reduced. The introduction of the cross-correlation has not brought evident improvements to our results: the two sets of locations (without and with the application of the cross-correlation technique) are very similar to each other. This can be commented saying that the use of the crosscorrelation has not substantially improved the precision of the manual pickings. Probably the pickings reported by the IDC are good enough to make the random picking error less important than the systematic error on travel times. As a further justification for the scarce quality of the results given by the cross-correlation, it should be remarked that the events included in our data set don’t have generally a good signal to noise ratio (SNR): the selected sequence is composed of weak events ( magnitude 4 or smaller) and the signals are strongly attenuated because of the large distance between the stations and the hypocentral area. In the local scale, in addition to the cross-correlation, we have performed a signal interpolation in order to improve the time resolution. The algorithm so developed has been applied to the data collected during an experiment carried out in Israel between 1998 and 1999. The results pointed out the following relevant conclusions: a) it is necessary to correlate waveform segments corresponding to the same seismic phases; b) it is not essential to select the exact first arrivals; and c) relevant information can be also obtained from the maximum amplitude wavelet of the waveforms (particularly in bad SNR conditions). Another remarkable point of our procedure is that its application doesn’t demand a long time to process the data, and therefore the user can immediately check the results. During a field survey, such feature will make possible a quasi real-time check allowing the immediate optimization of the array geometry, if so suggested by the results at an early stage.

Tax Treaty Override

What exactly is tax treaty override ? When is it realized ? This thesis, which is the result of a co-directed PhD between the University of Bologna and Tilburg University, gives a deep insight into a topic that has not yet been analyzed in a systematic way. On the contrary, the analysis about tax treaty override is still at a preliminary stage. For this reason the origin and nature of tax treaty override are first of all analyzed in their ‘natural’ context, i.e. within general international law. In order to characterize tax treaty override and deeply understand its peculiarities the evaluation of the effects of general international law on tax treaties based on the OECD Model Convention is a necessary pre-condition. Therefore, the binding effects of an international agreement on state sovereignty are specifically investigated. Afterwards, the interpretation of the OECD Model Convention occupies the main part of the thesis in order to develop an ‘interpretative model’ which can be applied every time a case of tax treaty override needs to be detected. Fictitious income, exit taxes and CFC regimes are analyzed in order to verify their compliance with tax treaties based on the OECD Model Convention and establish when the relevant legislation realizes cases of tax treaty override.

The European External Action Service and the Implementation of the 'Union Method' in European Foreign Policy

The European External Action Service (EEAS or Service) is one of the most significant and most debated innovations introduced by the Lisbon Treaty. This analysis intends to explain the anomalous design of the EEAS in light of its function, which consists in the promotion of external action coherence. Coherence is a principle of the EU legal system, which requires synergy in the external actions of the Union and its Members. It can be enforced only through the coordination of European policy-makers' initiatives, by bridging the gap between the 'Communitarian' and intergovernmental approaches. This is the 'Union method' envisaged by A. Merkel: "coordinated action in a spirit of solidarity - each of us in the area for which we are responsible but all working towards the same goal". The EEAS embodies the 'Union method', since it is institutionally linked to both Union organs and Member States. It is also capable of enhancing synergy in policy management and promoting unity in international representation, since its field of action is delimited not by an abstract concern for institutional balance but by a pragmatic assessment of the need for coordination in each sector. The challenge is now to make sure that this pragmatic approach is applied with respect to all the activities of the Service, in order to reinforce its effectiveness. The coordination brought by the EEAS is in fact the only means through which a European foreign policy can come into being: the choice is not between the Community method and the intergovernmental method, but between a coordinated position and nothing at all.
