O objeto primordial desta dissertação é conceituar a investigação criminal defensiva, sob a ótica da eficiência e do garantismo, e demonstrar a necessidade deste instituto nos ordenamentos jurídicos em que a investigação pública é tendencialmente acusatória. Para tanto, nos dois capítulos iniciais, esclarecem-se alguns aspectos gerais condizentes ao tema em análise, a saber: a definição de investigação criminal e suas principais características; a questão da parcialidade do Ministério Público e a investigação do crime por este órgão; e a definição de inquérito policial e sua disciplina legal no Brasil. Em seguida, aborda-se a relação da investigação defensiva com os princípios constitucionais da igualdade e da ampla defesa, que se encontram na base de um processo penal acusatório e asseguram às partes igual oportunidade de comprovarem os seus argumentos. Por conta disso, se um sistema jurídico prescreve a investigação do crime pelo próprio órgão acusatório, é de rigor que o imputado tenha direito equivalente, sob pena de se violar os mencionados direitos fundamentais. Ademais, a investigação defensiva, ao permitir a obtenção de elementos que serão contrapostos à investigação pública, amplia o campo cognitivo do Magistrado, o qual disporá de um maior número de dados materiais para fundamentar decisão acerca da viabilidade da acusação e da adoção de medidas cautelares. Após a análise constitucional da investigação defensiva, estuda-se o tratamento conferido pelo Direito estrangeiro a esta matéria, particularmente na Itália, onde o tema está em voga e é objeto de importantes e auspiciosos debates jurídicos. Ao final, a dissertação cuida da concretização da investigação defensiva, isto é, o modo como deve se desenvolver, as suas limitações, a utilização do seu resultado e a possibilidade de inserção no ordenamento jurídico pátrio. / The main subject of this dissertation is to create a concept of the criminal defense investigation, under the efficiency and the guarantism perspectives, and to demonstrate the need of such institute in the legal system in which the public investigation has an acusatory tendency. For this purpose, in the first two chapters, the dissertation clarifies certain general aspects regarding the subject under analysis, such as: the definition of criminal investigation and its main characteristics; the question of partiality of the Public Prosecutor\' s Office and the criminal investigation ran by this office; and the definition of criminal investigation and its legal regulation in Brazil. Following, the dissertation approachs the relation of defensive investigation with the constitutional principles of equality and of full defense, which are in the base of an accusatory criminal procedure and assure the parties equal opportunities to prove their arguments. For this reason, if a legal system provides for a criminal investigation to be conducted by the accusatory party itself, it is imperative that the accused has equivalent rights, otherwise the legal system will be violating the above mentioned fundamental rights. Furthermore, in allowing gathering elements which shall be confronted with the official investigation, the defense investigation expands the cognitive field of the Magistrate, who will have more material data to pronounce a decision regarding the accusation\'s viability and the adoption of cautionary measures. After the constitutional analysis of the defense investigation, the dissertation enters into the foreign law on this subject, particularly from Italy, where the matter is highly in evidence and is the subject of important and auspicious legal debates. In the end, the dissertation provides for the materialization of the defense investigation, i.e., the manner in which it shall be developed, its limitations, the use of its results and the possible insert in our national legal ordinance.

- The issue of the concept of criminal custody Man's personal freedom is the basic human right, however at the same time it is possible to restrict it in a democratic society under certain conditions defined beforehand. This thesis deals with the most serious personal freedom trial restriction - the institute of custody. Custody consists in a temporary personal freedom restriction of the defendant in a closed facility based upon a court decision. Custody is an utmost means and it shall be used only if its purpose cannot be reached by other measures. Custody is not a means of pressure on the defendant and it is unacceptable to misuse it; it si not a sanction measure either. Custody law is arranged particularly in the Penal Procedure Code, which sets the basic principles and conditions under which the defendant can be limited on their personal freedom with this procedure means.

These three reasons for custody are also indicated as getaway, collusion and surpass custodies. This personal freedom restriction may last only for a certain time,...
