"Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de Maîtrise en droit (L.L.M.)" / Une personne est injustement condamnée à l'emprisonnement. Elle est victime d'une erreur judiciaire. Plusieurs causes peuvent être à l'origine d'une telle injustice mais malheureusement il est difficile de le prouver. Le système de justice pénale au pays n'est pas à l'abri des condamnations injustifiées et plusieurs innocentes victimes en ont payé le prix. Or, comment une victime d'erreur judiciaire peut-elle prouver son innocence et ainsi recouvrer la liberté à laquelle elle a droit? Certes, l'aveu du coupable ou la découverte d'une nouvelle preuve peuvent servir de moyens de reconnaissance factuelle d'une condamnation injustifiée. Toutefois, certains obstacles procéduraux comme les délais d'appel, les règles d'admissibilité de la preuve nouvelle ou encore le mécanisme de correction des erreurs judiciaires prévu aux articles 696.1 et suivants du Code criminel peuvent compliquer le scénario. Avant le 4 juin 2002, cette dernière procédure était visée par l'article 690 du Code. Toutefois, suite à de nombreuses critiques ainsi qu'à une consultation publique orchestrée par le gouvernement canadien, des modifications législatives ont été apportées à cette procédure. Mais celles-ci sont-elles suffisantes? Nous pensons que certaines des modifications sont grandement appréciables. Cependant, la structure d'évaluation des dossiers et de recommandation des dossiers au ministre de la Justice mériterait la mise en place d'un comité formé d'avocats indépendants pour conseiller ce dernier. Cela est nécessaire afin de réduire à néant tout conflit d'intérêts potentiel de la part du Ministre et d'assurer la transparence du processus en cause. / A person is unjustly condemned to imprisonment. He or she is victim of a wrongful conviction. Many causes can lead to such an injustice but unfortunately, it is hard to prove. The country's criminal justice system makes no exception to wrongful verdicts of guilt and many innocent people have paid the priee. Thus, how can a person victim of a wrongful conviction prove his innocence and recover his rightful freedom? Of course, the confession of the true guilty person, the discovery of new evidence or a special inquiry commission are all ways of recognizing factually an unjust guilty verdict. However, certain procedural obstacles such as appeal delays, rules of admissibility of new evidence or even the procedure for correcting wrongful convictions provided under article 696.1 and following of the Criminal code, can complicate the scenario. Before June 4, 2002, the latter procedure was provided under article 690 of the Code. However, following great criticism as well as a public consultation orchestrated by the Canadian government, legislative modifications were brought to that procedure. Are the modifications made to the procedure sufficient? We believe that some of them are greatly appreciable. However, the evaluation and case recommendation structure to the Minister deserves the creation of a committee constituted by attorneys fully independent of the Minister able to advise him or her. This is necessary in order to fully reduce any potential conflicts of interest by the Minister and would ensure transparence of the process in question.

Com as mudanças do mundo moderno surgiu uma justificada preocupação global com a crescente prática de delitos contra a ordem econômica e a dificuldade que as autoridades enfrentam para apurá-los. Para socorrê-las surge o acordo de leniência, instrumento de investigação altamente eficaz de ampla aplicação em nações estrangeiras. Mas não por isso, este instituto deve ser importado ao nosso ordenamento tal qual utilizado em terras alienígenas, ignorando-se os direitos do delator e em flagrante desrespeito aos princípios constitucionais. Diante dessa problemática, o presente trabalho tem por objetivo realizar uma análise crítica acerca deste acordo e dos reflexos que provoca no âmbito penal, a fim de serem detectadas as falhas e incongruências de seu procedimento, bem como os seus aspectos inconstitucionais e, com isso, contribuir para a sua adequação ao ordenamento jurídico e seu desenvolvimento como meio de investigação para o combate aos crimes contra a ordem econômica, sobretudo, a formação de cartel. Em vista disso, será feito um estudo inicial sobre a relação entre Direito e Economia, Direito Concorrencial, seus interesses e a necessidade de tutela, inclusive pela via penal, da concorrência pelo Estado. Posteriormente, passar-se-á à análise das condutas anticoncorrenciais e dos crimes contra a ordem econômica, constatando-se os empecilhos para a investigação de tais delitos. A partir deste exame, far-se-á uma apresentação do acordo de leniência, suas origens, sua regulamentação em outros países para, então, a par das preocupações éticas que o circundam, realizar uma apreciação crítica dos efeitos que provoca na esfera penal. Ao final, em concordância com a necessidade de se manter o instituto, o presente trabalho buscará sanar as deficiências da atual legislação sobre o tema e, inclusive, da recémaprovada Lei nº 12.529/2011 , propondo alterações que visam minimizar a discricionariedade, o subjetivismo e a insegurança jurídica que permeiam o acordo, de modo a adequá-lo aos ditames constitucionais e torná-lo mais atraente aos candidatos. / The modern world has undergone changes that justify the global concern with the increasing occurrence of criminal offenses against the economic order and with the difficulty the authorities face to ascertain them by investigation.

In spite of that, this institute shall not be imported to our legal system as regularly applied abroad ignoring the rights of the delator and of flagrant disrespect to constitutional principles. Before this issue, the current paper has the objective to promote a critical analysis concerning the leniency agreement and the reflexes it triggers in the criminal field, in order to evidence the flaws and incompatibility of its procedure, as well as its unconstitutional aspects, by that, be able to contribute with its suitability to the criminal systemand to its development as a mean of investigation to fight crimes against the economic order, overall, the formation of cartel. Due to that, an initial study is proposed about the relation between Law and Economics, Competition Law, their interests and the need of tutelage containing the criminal manner and the competition by the State. Later, an analysis of anti-competitive conducts and of crimes against the economic order containing the impediments to the investigation of such criminal offenses. Resulting from this examination, there will be a presentation of the leniency agreement, its origins, regulations in other countries, so that, in addition to the ethical concerns that surround the agreement, be possible the fulfillment of critical appraisal to the effects it causes in the criminal field. Finally, in accordance to the need to support the institute, the current paper seeks to heal the gaps of the current legislation related to the theme including, the newly approved Law number 12.529/2011 proposing changes that aim at minimizing the discretion, subjectivism and juridical insecurity that permeates the agreement, in a way to adequate it to the constitutional precepts and make it become more engaging to the candidates.

For such purpose, we will initially analyze some basic concepts to establish assumptions for the development of this work. Later on, we will analyze the Clean Company Act Law as a whole. Finally, and doing so, we will focus on the analysis of the leniency agreement encompassing its main aspects and controversial issues linked to the institute / O objetivo desta dissertação é analisar o instituto do acordo de leniência, previsto pela Lei nº12.846, de 1º de agosto de 2013, também denominada de Lei Anticorrupção Brasileira, bem como o seu enquadramento como uma modalidade de atuação contemporânea da Administração Pública de forma consensual, não imperativa. Para tanto, analisaremos, inicialmente, noções fundamentais necessárias ao estabelecimento de premissas para o desenvolvimento deste trabalho. Posteriormente, será feita uma contextualização da Lei Anticorrupção e, por fim, adentraremos à análise do acordo de leniência, com foco em seus principais aspectos e questões polêmicas inerentes ao tema

Esta pesquisa tem como hipótese o fato de que a corrupção desponta como uma questão de significativo relevo no cenário político, social e econômico dos países, tendo profunda imbricação com o desenvolvimento e estrutura institucional das nações. Um dos aspectos da estrutura institucional implicados se refere justamente à arquitetura normativa, a qual deve se ver dotada de instrumentos básicos e eficazes para um adequado enfrentamento do problema. Nesse contexto é que a novel Lei Anticorrupção se apresenta como mais um diploma a complementar o microssistema brasileiro de combate à corrupção, incrementando instrumentos punitivos, consensuais e de mutação de culturas corporativas. A harmonização sancionatória e o alinhamento dos diferentes atores encarregados da persecução, nesse viés, se apresentam como os mais candentes desafios a serem superados pelos operadores do direito. Cuidou-se, pois, de se apresentar os novos instrumentos e hipóteses-tipo com as respectivas sugestões de harmonização sistêmica. / This research has as hypothesis the fact that corruption emerges as a matter of significant importance in the political, social and economic scenario of the countries, having deep imbrication with the development and institutional structure of the nations. One of the aspects of the institutional structure involved is precisely the normative architecture, which must be equipped with basic and effective instruments for an adequate confrontation of the problem. In this context, the novel Anticorruption Law presents itself as another diploma complementing the Brazilian anti-corruption micro-system, increasing punitive, consensual and mutating corporate culture. The sanctioning harmonization and the alignment of the different actors in charge of the persecution, in this bias, are presented as the most burning challenges to be overcome by the operators of the law. Therefore, the new instruments and standard hypotheses were presented with the respective suggestions for systemic harmonization.

Doctor Legum - LLD / Competition law and its enforcement have become necessary tools in the face of trade liberalisation. Nowhere is this more evident than in the area of cross-border cartels. The global South is steadily becoming aware of this. With the advent of globalisation and trade liberalisation, individual economies have become intrinsically linked. Anti-competitive conduct in one territory may have an impact in another territory. Therefore, an effective regional competition law framework complements trade liberalisation, especially in light of the principal objective of the South-South regional economic communities: the deepening of regional integration, in order to realise economic development and alleviate poverty. Cartel practices, such as, market allocation cartels, are in direct contradiction to this primary objective. This is when enforcement collaborations in South-South regional economic communities becomes crucial. The regional legal instruments of the Common Market for Eastern and Southern Africa, the East African Community, the Southern African Customs Union and the Southern African Development Community make provision for enforcement collaborations among Member States. To facilitate collaboration, regional competition authorities have been created to investigate, among other things, cross-border cartels. Within these economic communities, there is a strong case for enforcement collaborations, as evidence shows that the majority of the firms engaging in cartels are the so-called Regional Multinational Corporations. They operate throughout the territories of Member States. Additionally, the international nature of cartels, such as, private international cartels and export cartels, provide an opportunity for South-South co-operation to be utilised. However, this co-operation has not been utilised to the fullest extent, especially with reference to cross-border cartel activities. This has been attributed to various factors, such as, institutional incapacities, resource austerity, the absence of common procedural rules, the lack of adequate investigatory tools, and political ineptitude. As a solution, this current study makes specific recommendations that are directed at enhancing the effectiveness of South-South collaborations pertaining to cross-border cartel activities.

For this, it’s necessary a rescue on the development of the idea of freedom, and then get to free competition as principle underlying the Economic Order. The democratic state, established in the 1988 Constitution, is the contemporary stage of defense of legal, economic and social values which are intended to guarantee national development, and promote the construction of a free, fair and inclusive society. It will be seen that the mentioned Economic Policy correlates with the Criminal Policy idealized by the State. There will be a theoretical and historical establishment that takes account of the evolution of the discipline of Antitrust in Brazil. There will also find space in this paper for the illustration of the idea of Antitrust Sanctioning Law to see how the Government may, very effectively, investigate and punish officials based on their own standards, serving as a counterpoint to the Economic Criminal Law. This route of parallel paths between administrative and legal marks of Antitrust is clearly reflected in the Leniency Agreement institute. Thus, a conceptual frame about what will be the object spanned by the leniency agreement will be presented: cartels. Will fetch up the demonstration of various types of cartel, with special emphasis on bidding cartels. Finally, the work dissects the institute's Leniency Agreement itself, solidifying its legislative and conceptual basis, and presenting their rules. Through the combination of legal rules, will be shown the way to be observed when entering into an agreement. Based on this view, will be presented the Historical of Conducts of a Leniency Agreement in a bidding cartel. Also adds up the context of the Leniency Agreement in international models implemented in the United States and European Union. In addition, this paper will seek to give lights to the criteria for distinguishing between administrative predictions arising from decisions made by administrative courts, especially the Administrative Council for Economic Defense, and its possible implementation in criminal area, suggesting alternatives that may match in an harmonic way the application of the institute and the preservation of its effects. / O presente trabalho tem por objetivo lançar algumas luzes acerca da aplicabilidade do Acordo de Leniência no Sistema Brasileiro de Defesa da Concorrência. Para isso, vislumbrou-se como necessário um resgate acerca do desenvolvimento da ideia de liberdade, para então se chegar à livre concorrência como princípio inspirador da ordem econômica. O Estado Democrático de Direito, estabelecido na Carta de 1988, representa o estágio contemporâneo de defesa de valores jurídicos, econômicos e sociais que têm por finalidade garantir o desenvolvimento nacional, além de promover a construção de uma sociedade livre, justa e solidária. Será visto que a mencionada Política Econômica encontra correlação com a Política Criminal idealizada pelo Estado. Será feito um apurado teórico-histórico que dê conta da evolução do disciplinamento do Antitruste no Brasil. Também encontrará espaço no presente trabalho a ilustração da ideia de Direito Antitruste Sancionador, a fim de que se possa perceber como a Administração Pública pode, muito eficazmente, investigar e punir agentes com base em suas próprias normas, servindo de contraponto ao Direito Penal Econômico. Essa via de caminhos paralelos entre administrativização e judicialização do Antitruste encontra reflexo claro no instituto do Acordo de Leniência. Para tanto, será apresentado um panorama conceitual acerca do que venha a ser o objeto de combate abarcado pelo Acordo de Leniência: os cartéis. Buscar-se-á a demonstração dos diversos tipos de cartel, dando especial relevo aos cartéis em licitação. Por fim, o trabalho esmiúça o instituto do Acordo de Leniência em si, firmando sua base legislativa, conceitual e apresentando suas regras de procedibilidade. Por meio da combinação de disciplinamentos legais, será demonstrado o caminho a ser observado quando da celebração de um Acordo. A partir dessa visão, será feita a demonstração do Histórico de Condutas do Acordo de Leniência num cartel em licitação. Acrescenta-se também a contextualização dos modelos internacionais de Acordo de Leniência implementados nos Estados Unidos e União Europeia. Além disso, buscar-se-á dar relevo aos critérios de distinção existentes entre as previsões administrativas oriundas das decisões proferidas pelos órgãos da administração, especialmente o Conselho Administrativo de Defesa Econômica e a sua possível implementação na seara penal, sugerindo alternativas que possam compatibilizar de forma harmônica a aplicação do instituto e a preservação dos seus efeitos.
