En 2015, la FAO estimait qu’environ 795 millions de personnes sont sous-alimentées dans le monde. Les Nations Unies ont régulièrement qualifié cette situation « d’atteinte à la dignité humaine ». La coopération internationale est légitimement devenue dans ce contexte un moyen privilégié de lutter contre la malnutrition. Cependant, l’alimentation est au carrefour de nombreuses problématiques. Certains Etats sont soucieux d’affirmer leur autosuffisance alimentaire tandis que d’autres rencontrent des difficultés à gérer leurs surplus. Les enjeux de qualité sanitaire ou nutritionnelle côtoient les inquiétudes liées à la diminution accélérée de la diversité génétique. Face à ces préoccupations diverses, les aliments ont fait l’objet de nombreuses règles internationales. Certaines favorisent la libéralisation de leur production et de leur commerce, au détriment parfois d’une prise en compte du niveau de développement des pays, de la diversité biologique ou de la qualité des aliments. D’autres tiennent compte de ces questions mais leur articulation paraît délicate avec les règles de la libéralisation économique. Pourtant, les Etats ont érigé l’accès à l’alimentation comme un objectif mondial et la cohérence du droit international semble indispensable pour sa réalisation. La présente étude vise ainsi à déterminer dans quelle mesure le droit international, caractérisé par la fragmentation de ses règles, contribue à l’amélioration des conditions d’accès à une alimentation adéquate au niveau mondial. / In 2015, FAO estimated that approximately 795 million people are undernourished in the world. The United Nations has regularly qualified this situation as “a violation of human dignity”. In this context, the international cooperation legitimately became a privileged means to fight against malnutrition. However, the access to food is at the crossroads of numerous problems. Some States are eager to assert their self-sufficiency while others meet difficulties managing their surpluses. Health or nutritional quality issues join concerns about the accelerated loss of genetic diversity. Responding to these various concerns, food has been the subject of many international rules. Some promote the liberalization of their production and trade, sometimes to the detriment of a consideration of the level of development of countries, of the biological diversity or the quality of food. Some take account of these issues but their coordination seems difficult with the rules of economic liberalization. Nevertheless, States set up the access to food as a global goal and the coherence of international law seems essential for its achievement. The present study aims to determine to what extent international law, characterized by the fragmentation of its rules, contributes to improving the conditions of access to adequate food at the world level.

Il n’existe pas de modèle idéal en matière de transition énergétique. En effet, même si certains pays, à l’instar de la France et l’Italie, disposent d’un système énergétique prenant en compte des objectifs de développement durable, certaines limites peuvent freiner le développement de la transition énergétique. Une mise en oeuvre efficace de la transition énergétique doit nécessairement prendre en compte les exemples des autres pays, ce qui aura nécessairement pour objet d’entraîner une remise en cause profonde des régimes juridiques encadrant le secteur de l’électricité. Les différences qui caractérisent les orientations en matière énergétique en France et en Italie justifient, à notre sens, un rapprochement entre ces deux pays dans le cadre de ce travail. Dans ce contexte, une étude critique des avantages et des limites du régime juridique français, à l’aune du cas italien, est ainsi proposée. L’une des vocations de ce travail est ainsi de faire évoluer positivement les règles de droit français en matière de transition énergétique, à l’aide des mécanismes juridiques du droit comparé. / There is no ideal model for energy transition. Although some countries, such as France and Italy, have an energy system that takes into account sustainable development objectives, various limitations can limit the development of energy transition. For energy transition to take place effectively, the examples of other countries must be taken into account. Such energy transitions of course, will be subject to in-depth scrutiny by the legal regimes that govern the electricity sector. The differences in the energy guidelines in France and Italy justify, in our view, a reconciliation between these two countries as part of this work. In this context, a critical study of the advantages and limitations of the French legal system, in the light of the Italian case, is therefore proposed. One of the objectives of this work is how to positively develop the rules prescribed by French law on energy transition, using the legal comparative law mechanisms.

Les crises financières internationales ne se présentent pas comme des événements rares et isolés dans le temps. Des dénominateurs communs classiques à toute crise financière se retrouvent dans chaque cas historique : la détérioration des indicateurs macroéconomiques, la psychologie et les paniques des investisseurs, la spéculation. La problématique des dettes souveraines ne relevait jusqu’à présent principalement que des pays en développement, alors que les récentes perturbations financières ont démontré que les pays développés pouvaient également être gravement affectés. L’objectif de ce travail est d’analyser les évolutions du cadre juridique de la gestion des dettes souveraines pour réunir des éléments qui permettent de comprendre le choix normatif privilégié par chaque opérateur. L’actuel scénario d’endettement des États souverains entraîne nécessairement un bouleversement irréversible des règles et des structures juridiques connues qui visent à assurer le bon fonctionnement de l’économie mondiale. Face à l’actuelle incertitude normative, il est primordial d’étudier les supports du financement souverain, le traitement des crises, les propositions de réformes visant à améliorer le système et le rôle des institutions multilatérales dans la gestion de la dette souveraine. Après avoir déterminé l’existence d’un engagement international de gestion des dettes souveraines, nous plaidons pour la mise en œuvre d’un ensemble normatif d’outils conçus pour intégrer les réglementations nationales sur la base de modèles préexistants. / Historically, international financial crises do not occur in isolation but rather go hand in hand with the deterioration of macroeconomic indicators, investor panic and speculation. Until recently, the sovereign debt issue has principally concerned developing countries. However, the recent financial turmoil has revealed that developed countries can similarly be severely affected. Since the beginning of the 20th century, experts in international law have periodically discussed the possible remedies to the endemic situation of sovereign indebtedness. In 2001, the International Monetary Fund launched a proposal for a Sovereign Debt Restructuring Mechanism known as the ‘Krueger Plan’; this was quickly abandoned in 2003. Due to the present economic and political cul-de-sac, the legal framework of sovereign debt management strongly preoccupies the international community. The current sovereign debt scenario necessarily involves an irreversible disruption of the legal rules and structures that currently support a proper functioning global economy. This doctoral thesis analyses the evolution of the legal framework and the normative choices favoured by each actor. Identifying which particular legal issues are essential to evaluate such complexity allows us to deepen the theoretical and practical suggestions designed to facilitate the resolution of sovereign debt crises. After establishing the leading international requirements for sovereign debt management, this thesis advocates the implementation of a normative set of tools designed to integrate domestic regulations on the basis of previous models. / Internationale Finanzkrisen erweisen sich als nicht seltene und zeitlich unbegrenzte Ereignisse. Jeder Finanzkrise in der Historie haften die gleichen klassischen Charakteristiken an: die Beschädigung makroökonomischer Indikatoren, der Psychologie sowie die Panik der Investoren, Spekulationen. Darüber hinaus beschränken sich die aktuellen Finanzstörungen nicht mehr nur auf Entwicklungsländer. Das Ziel dieser Arbeit besteht darin, die Entwicklung des Rechtsrahmens der Verwaltung souveräner Schulden zu analysieren, um Elemente zusammenzutragen, die es erlauben die bevorzugten normativen Entscheidungen jedes Akteures zu verstehen, zu bewerten und im Anschluss entsprechend Handlungsanweisungen zu geben. Das gegenwärtige Szenario der Verschuldung souveräner Staaten führt unweigerlich zu einer unumkehrbaren Umwälzung der bekannten Rechtsverordnungen und -strukturen, die auf die Gewährleistung eines reibungslosen Funktionierens der Weltwirtschaft abzielen. Angesichts der gegenwärtigen normativen Unsicherheit, ist es von größter Bedeutung die Auseinandersetzung mit finanziellen Krisen, die entsprechenden Reformvorschläge, die Suche nach Systemverbesserungen hinsichtlich einer Marktregulierung und die Rolle der multilateralen Institutionen bezüglich der Verwaltung souveräner Schulden genauer zu untersuchen. Nach der Feststellung des Vorliegens einer internationalen Verpflichtung zum Staatsschuldenmanagement wird die Einführung einer Reihe normativer Werkzeuge befürwortet, um nationale Vorschriften auf Grundlage bereits bestehender Modelle zu integrieren.

O estudo analisa alguns dos aspectos mais relevantes do fenômeno da intervenção do Estado no campo econômico-social, em especial, no que diz respeito ao Direito Penal como instrumento de tutela dos interesses e valores socialmente prezados e consagrados constitucionalmente neste campo. Para tanto, foi abordado o histórico fático e normativo do ordenamento constitucional econômico-social como objeto do Direito Econômico e do Direito Penal Econômico. A partir daí, são delineadas as características e principais peculiaridades da delinquência econômica moderna, bem como apurada sua flagrante repercussão na atualidade. Tais fatores demandam a adaptação do Direito Penal por meio da revisão de alguns de seus dogmas. Por fim, são tecidas propostas de reformulação do pensamento tradicional acerca da estrutura típica e das sanções aplicáveis aos crimes praticados em face da ordem econômico-social. / The study examine some of the most important aspects of the phenomenon of state intervention in the economic and social area, particularly, with regard to criminal law as an instrument of protection of social interests and values cherished and constitutionally enshrined in this field. For this, was addressed the factual and legislative history of the constitutional economic-social as the object of Economic Law and Economic Criminal Law. From there, outlining the main characteristics and peculiarities of modern economic crime, and found their striking effect today. These factors require the adaptation of the Criminal Law by reviewing some of its dogmas. Finally, are woven proposals to recast the traditional thinking about the typical structure and penalties for crimes committed in the face of economic and social order.

La puissance d'achat est appréhendée par le droit européen comme un pouvoir de marché entraînant des effets pro et anticoncurrentiels sur le marché intérieur. Les dispositions de droit positif concernant les pratiques restrictives de concurrence et les concentrations d'une part, ainsi que les abus de domination d'autre part, correspondent à deux hypothèses d'appréhension de la puissance d'achat par le droit de la concurrence. Si les premières relèvent d'une logique structurelle tempérée, les abus de domination obéissent à une logique ordo- structurelle forte teintée d'un élément subjectif afférent au comportement. Dans le premier cas, la puissance d'achat est considérée comme nocive pour la concurrence si son degré est trop important. Dans le second cas, elle est présumée nocive et réprimée si elle est exercée abusivement. Les objectifs de politique concurrentielle européenne de protection de l'efficience globale de marché et les outils normatifs afférents témoignent toutefois d'une approche limitative de la puissance d'achat. Les lois actuelles démontrent certaines faiblesses dans l'appréhension de la puissance d'achat, celle-ci dépassant les situations monopso- ou oligopsonistiques et s'exprimant notamment comme pouvoir de marché relatif. Les modifications législatives proposées dans le sens d'une appréhension de la puissance d'achat dans ses différentes acceptions économiques pourraient toutefois permettre de protéger utilement l'ensemble des acteurs économiques concernés sans se limiter au consommateur final. / European law considers buyer power as a market power able to create pro and anticompetitive effects on the internal market. Buyer power is concerned by the application of competition law in cases of anticompetitive pratices and mergers on the one hand and abuse of dominance on the other hand which differents economic logics. Rules about anticompetitive practices and mergers focuse on the buyer power's degree which define pro and anticompetitive effects. Rules about abuse of dominance focuse on the abuse of a dominant buyer and assume anticompetitive effects. The assessment of buyer power under competition law is substantially influenced by the general competition policy concept which is aimed at maximising consumer welfare. Competition law considers buyer power predominantly as an absolute market power and not in the form of bargaining power exercised bilaterally vis-à-vis individual suppliers. Nevertheless european existing law is not able to consider all situations of buyer power. Monopolistic or oligopolistic situations do not reflect the reality of buyer power which also significate a relative market power. It seems that proposed legislative modifications aiming to consider the economic reality of buyer power on the entire market could lead to a better protection of all concerned competitors and not only the end consumer. / Das europäische Recht tendiert dazu Nachfragemacht als Marktmacht aufgrund ihrer wettbewerbspositiven und -negativen Effekten auf dem Binnenmarkt zu erfassen. Die Nachfragemacht im europäischen Recht wird zum einen durch das Kartellrecht, die Fusionskontrolle und zum anderen durch die Missbrauchskontrolle erfasst. Diese Normen entsprechen alle einer wettbewerbspolitischen Orientierung, können jedoch aufgrund ihrer jeweiligen Wettbewerbssysteme unterschieden werden. Zum einem erfassen das Kartellrecht und die Fusionskontrolle die Nachfragemacht als Marktmacht, die aufgrund ihres Grades positive und negative Auswirkungen auf die Marktstruktur bewirken kann. Zum anderen wird die Nachfragemacht aber auch vom europäischen Missbrauchsverbot erfasst. Es wird anders als im Kartellrecht oder bei der Fusionskontrolle nicht ermittelt, inwiefern Nachfragemacht den Wettbewerb möglicherweise schädigt, sondern ob der Wettbewerb wegen der Ausnutzung dieser Marktmacht geschädigt wird. Jedoch erfassen die europäischen Rechtsnormen den ökonomischen Ansatz der Nachfragemacht auch anhand des Monopsonmodell nur teilweise und stellen deshalb eine begrenzte juristische Analyse dieses Phänomens dar. Dabei schliesst das europäische wettbewerbspolitische Leitbild den Schutz bilateraler Verhältnisse aus seinem Anwendungsbereich aus wohlfahrtsneutralen Gründen aus. In diesem Sinne wird Nachfragemacht prinzipiell als absolute Marktmacht definiert. In der Weise einer vereinfachten aber zugleich wirksamen Erfassung von Nachfragemacht durch das europäische Recht könnten jedoch die vorgeschlagenen Änderungen der aktuellen Rechtsnormen zu einem umfassenden Schutzes aller Marktteilnehmer führen.

Ce travail de recherche a pour objectif d'apporter un éclairage et une compréhension sur l'évolution du droit des affaires en Chine et plus particulièrement sur les outils de protection des investissements pour les étrangers dans ce pays. Cet ouvrage analyse les incidents liés à la protection juridique des investissements étrangers ainsi que l'effectivité des voies de recours en cas de différents. / The objective of this thesis is to bring insights into the understanding of the evolution of business law in China and in particular on the tools of investment protection used by foreigners in this country. This paper analyses the events related to the protection of foreign investments as well as the efficiency of arbitrative solutions in the case of problems.

O propósito deste trabalho é analisar a regulação jurídica brasileira da intervenção do Estado, por meio da tributação, sobre a economia. Esta tarefa se desenvolve em três momentos teórico, dogmático e histórico/institucional que se estendem ao longo dos três capítulos do trabalho, respectivamente. O primeiro momento lida com a dimensão doutrinária jurídica de análise, interpretação, metodologia e abordagem deste fenômeno. Buscamos recuperar historicamente a trajetória da doutrina do direito tributário brasileiro em contraposição à doutrina do direito econômico brasileiro, recuperando o conceito de extrafiscalidade como ponto limite da doutrina tributária e ponto de partida para uma análise sistemática da intervenção estatal pela tributação. O segundo momento é a tentativa de traçar uma abordagem pertinente para essa análise da extrafiscalidade tributária pelo direito econômico, problematizando-a à luz do ordenamento brasileiro, sobretudo, em nível constitucional. Para tanto, assumimos as categorias de Eros Roberto Grau, sobre a intervenção estatal na economia, e as de Richard A. Musgrave, sobre as finalidades da política fiscal, para aprofundarmos a classificação do fenômeno quanto à sua forma (indução), suas técnicas (oneratórias/ desoneratórias), suas finalidades (extrafiscalidade alocativa/ extrafiscalidade distributiva/ extrafiscalidade estabilizadora) e seu regime de competências. O terceiro momento remonta um panorama da evolução histórica do sistema tributário nacional, seus principais diplomas normativos, encadeado em uma narrativa que envolve os atores, interesses, ideias e modelos institucionais e jurídicos adotados pelo Brasil, principalmente em torno do federalismo fiscal. Por fim, concluímos haver uma tendência à separação progressiva do regime jurídico da fiscalidade e da extrafiscalidade, por conta da própria trajetória econômica, política, histórica, normativa e institucional do sistema tributário brasileiro. Fato diante do qual resta ao conhecimento jurídico, como saber tecnológico que é, reconhecer, compreender, se aprofundar e performar. / The purpose of this paper is to analyze the legal regulation of the Brazilian state intervention through taxation on the economy. This task is unfolded in three parts - theoretical, dogmatic and historical/ institutional - that are developed in the three chapters of the work, respectively. The first deals with the doctrinal legal dimension of analysis, interpretation, methodology and approach of this phenomenon. We seek to recover the historical trajectory of the Brazilian tax law doctrine in contrast with the Brazilian economic law doctrine, recovering the concept of taxation based on police powers as a threshold point of the tax law doctrine and a starting point for a systematic analysis of state intervention through taxation. The second part is an attempt to draw a pertinent approach to the analysis of the taxation based on police powers by the economic law doctrine, questioning it under the lens of the Brazilian legal system, especially at the constitutional level. Therefore, we assume Eros Roberto Graus categories about the state intervention in the economy, and Richard A. Musgraves categories about the aims of fiscal policy, to further classify the phenomenon by its shape (induction), its techniques (overtax/ exonerate), its purposes (allocative/ distributive/ stabilizer) and its regime of competence. The third part is an overview of the historical evolution of the Brazilian tax system, its main laws and regulatory instruments, through a narrative that involves actors, interests, ideas, and institutional and legal models adopted by Brazil, particularly around fiscal federalism. Finally, we conclude that there is a tendency to a progressive separation between the legal regime of taxation based on revenues and of the legal regime of taxation based on police powers because of the economic, political, historical, normative and institutional trajectory of the Brazilian tax system. As a consequence of that, we believe that legal thought should, as technological knowhow, recognize this fact, understand it, deepen it and perform it.

O objeto do presente trabalho é a análise das mudanças no regime jurídico do investimento estrangeiro ocorridas na última década. Após o estudo histórico sobre o desenvolvimento desse regime, as quatro tendências que conduziram a elaboração das regras daquele período são examinadas. A primeira delas foi a criação de regimes regionais, como as regras sobre o investimento internacional do NAFT A, ASEAN, APEC e Mercosul. A segunda, as tentativas de estabelecimento de um regime multilateral, como comprovam não só as negociações do MAI e das TRIM\'s, nos quadros da OCDE e OMC, como a consolidação pelo Banco Mundial das Diretivas sobre o investimento direto estrangeiro. Em terceiro lugar, o surgimento de normas internacionais setoriais, a exemplo do Tratado da Carta da Energia. E, por último, o crescimento extraordinário do número de acordos bilaterais sobre a matéria. O estudo leva em consideração a jurisprudência internacional, principalmente as sentenças proferidas pelo CIRDI. O exame dessas quatro tendências é seguido pelo estudo de dois regimes regionais que dizem respeito aos interesses brasileiros: o do Mercosul e o da ALCA. Se comparado com os regimes anteriores, aquele dos anos 90 se distingue por privilegiar a flexibilização das regras sobre o fluxo de capitais e o incremento de seu ganho. Preocupações com regras concernentes à proteção do investimento estrangeiro parecem estar ultrapassadas em razão de dois motivos. Inicialmente, pela implementação de seguros e garantias contra riscos políticos que, além de contornar o risco decorrente das interferências governamentais nos investimentos, também minimizou as discussões sobre as indenizações. Em segundo lugar, pelo endosso dado pela maioria dos países em desenvolvimento às políticas neoliberais -o que inibiu a ação governamental no regime doméstico do investimento internacional- e pela concorrência entre esses países em atrair esse investimento. O direito internacional dos investimentos passou a contar com poucas lacunas, a basear-se menos no costume e a formalizar-se em instrumentos. Questões vitais em décadas anteriores, como aquelas relativas à cláusula Calvo e aos critérios indenizatórios, foram resolvidas por tratados ou pela jurisprudência. Esta tomou-se abundante, consolidando um entendimento conservador. Objetivamente, pouco restou do discurso inflamado dos anos 60 e 70 sobre a NOEI. Desmontou-se o binômio investimento e desenvolvimento, desarticulando-se um sistema anterior chamado de Direito Internacional do Desenvolvimento. Essa desarticulação deu-se por caminhos diversos. O direito internacional dos investimentos, antes objeto de Resolução da ONU, teve seus debates transpostos para outras organização, como o Banco Mundial A preocupação com o desenvolvimento foi realocada de capítulo do Direito Econômico Internacional para o campo dos Direitos Humanos. Das quatro tendências acima, uma delas parece que não terá continuidade: o tratamento setorial da matéria. Todavia, nos próximos anos, as outras três continuarão a ser seguidas: não há indicação de refluxo nos acordos bilaterais; a busca por um regime multilateral irá continuar, como aponta o compromisso assumido na reunião da OMC, em Doha de assinatura das TR!M\'S em 2005; e, finalmente, as negociações da ALCA, que incluem disposições sobre investimentos, indicam continuidade na tendência regional. / The purpose of this work is to analyze the changes introduced in the international legal regime applicable to foreign investment in the last decade. After an historical study on the development of this regime, the four trends that shaped the elaboration of these rules during this period are examined. Firstly, the tendency to the creation of international regional regimes -like NAFTA, Mercosur, ASEAN and APEC\'s special rules on investment- is analyzed. Secondly, the several attempts to establish a multilateral regime on foreign investment -as evidenced by the negotiation of the MAL in the OECD, and of the TRIM\'s, in the WTO, as well as the edition of the Guidelines on Foreign Direct Investment by the Word Bank- are reviewed. In the third place, the international rules applicable to investments in special sectors, as is the case of the Energy Chart Treaty, are focused. Finally, the increase in number of the bilateral treaties is examined. This study takes into account the international jurisprudence, mainly the awards rendered by the lCSID. This exam is followed by the study of two regional regimes that affect Brazilian interests: the Mercosur and the FTAA. If compared with the previous regimes, the one that prevailed in the nineties appears to be more concerned with both the flexibility of the rules on the flow of capitals and the increase of earnings. Concerns about rules on the investment protection have vanished for two main reasons. Initially, the availability of insurance and guaranties against political risks besides minimizing the risks presented by any governmental interference on the investor\'s control over its investment, also contributes to make issues on the value of indemnities irrelevant. In the second place, the majority of the developing countries not just endorsed neo-liberal policies, which made governmental restrictive postures on foreign investment difficult, but have started to compete against each other to attract foreign capitals. The International Law on Investments turned into a system with few gaps, based rather on written treaties than on customary law. Crucial issues of the past few decades, like these related to the Calvo doctrine or to indemnities criteria, were solved by treaties and arbitral decisions. Not only did the jurisprudence become abundant, but also consolidated conservative views on the matter. Objectively, very little remained of the fiery speech on the NEIO. The dual investment and development was undone and the previous system of the International Law of Development collapsed. This collapse was caused by different reasons. The most determining, however, is the fact that the International Law on Investment, based before on customary roles and precariously settled by UN\'s resolutions, were relocated to different fora, like the World Bank. The concern with development switched from an important chapter of the International Economic Law to Human Rights\' domain. Amidst the four trends pointed out in this work, apparently just one will be discontinued in the near future: the sectorial treatment of foreign investment. Nonetheless, the others will continue to be present: there is no evidence of reflux in the signing of bilateral treaties; the search for a multilateral regime will continue, as shown in the commitment made in the WTO Conference of Doha, in 2001, fixing for 2005 the signing of the agreement on TRIM\'s; and finally, the negotiation of FTAA, including dispositions on investments, indicates that the regional tendency will remain.

A Constituição de 1988, seguindo a moderna tendência de delegação à administração de funções que vão além do exercício de poder de polícia e de atividades econômicas pela via direta, traçou como objetivo da máquina pública a efetiva contribuição para o alcance de um modelo que equilibre, de um lado, as liberdades sociais, com amplo desenvolvimento e dignidade humana, e, de outro, o exercício da liberdade de iniciativa empresarial, fruto do modelo capitalista em vigor. Sob a ótica infraconstitucional, para alcançar tais objetivos, faz-se necessário repensar o papel do Direito, de modo que se busquem métodos que permitam a difícil, porém não impossível tarefa de equilibrar tais interesses. O Direito Econômico é a resposta para a concretização dessa tarefa, graças à sua vocação metodológica de integração dos ramos tradicionais do pensamento jurídico, aproximando teoria e prática. Partindo do tema da sanção ao abuso de poder econômico, este trabalho versa sobre a necessidade de uma melhor coordenação entre os direitos administrativo e penal, ambos legitimados a punir agentes que se exacerbem no exercício da liberdade de iniciativa, para que melhor se possa acomodar o arranjo institucional necessário aos objetivos traçados. Serão analisados, neste estudo, aspectos teóricos e legais das duas matérias, de modo que se identifiquem os temas e a s sanções que, embora independentes, devem ser coordenados tanto sob a ótica dos incentivos à cooperação dos agentes com as autoridades quanto sob a ótica de um direito único e de sanções eficazes. Analisar-se-ão, também, os modelos adotados em diversos países para tratar do tema e, ao final do trabalho, serão propostas melhorias legislativas e principiologia doutrinária para o nosso ordenamento. Com a criação de diversos órgãos administrativos judicantes, que, sem pretender substituir o Judiciário, procuram contribuir com o mencionado equilíbrio constitucional, tal como é o Conselho Administrativo de Defesa Econômica (Cade), ganha ainda mais relevo o já consagrado princípio da subsidiariedade penal, bem como a necessidade de efetiva garantia das garantias principiológicas de contraditório e da ampla defesa no campo da administração e do processo administrativo. A fortificação das estruturas processuais e procedimentais de coordenação das sanções administrativa e penal favorece não apenas o indivíduo, mas principalmente a coletividade, mediante a incorporação de um sistema mais ágil e especializado e principalmente dos incentivos para a prevenção de infrações, que decorre da certeza de aplicação da sanção em caso de abuso de poder econômico. / The Brazilian Constitution, following the modern trend to empower the public administration to develop tasks that goes beyond the classic policy powers and direct services, fixed as a goal to be implemented by them the achievement of a environment that combines, in one side, the social freedom, with special attention to the development of the human dignity and the overall development of the country, and, in the other side, the freedom of corporate initiative, as a premise of the capitalism. Under a infracontitucional point of view, to reach these goals is necessary to think about the role of the law itself, to search for methods that can give a solution to the hard- but not impossible- task of equalize the two sides mentioned above. The Economic Law is the answer to the achievement of the goal, thanks to its methodological vocation to integrate the traditional law topics, approximating legal theory and the human and markets behavior. Starting from the study of the sanction, this work talks about the need of a better coordination between administrative and criminal law, both legitimate under Brazilian law to punish those who violate the competition and freedom of initiative, which is necessary to achieve the new constitutional goals. Along the work it will be analyzed theoretical and legal aspects of administrative and criminal law to identify the aspects that needs a better coordination in terms of authority cooperation incentives and effectiveness, although the authorities remains independent to enforce the law. It will be also analyzed the overseas legislation and way of coordination between administrative and criminal authorities, and in the end of the work there will be some suggestions of law modifications and a doctrinaire principle. Considering the creation of several agencies that develop jurisdictional functions to contribute to the balance of constitutional goals mentioned above without the intention to substitute courts just as Conselho Administrativo de Defesa Econômica- CADE- the Brazilian competition authority- there is even more relevant to apply the principle of criminal law subsidiary and the due process of law in the field of administrative law and its procedural. The fortification of the process structure favors not only the individual but also the society as a whole, as its output is a better system to prevent and punish misconducts that derives of the certainty of punishment in cases of economic power abuse.
