The subject of this diploma thesis is discourse theory and its reflection on the style of judicial decision-making and argumentation. Discourse theory is based on the fundamental assumption that an interaction of more people is needed to achieve right and just knowledge. This is so because an individual is not capable of surmounting her or his own subjective perception of reality. On the contrary, a dialogue enables the articulation of opposing points of view and thus makes it possible to arrive at a more objective and just knowledge. The discourse theory of law, developed by J. Habermas and primarily by R. Alexy, ranks among the theories of legal argumentation with the dialogical approach to the desicion- making as a basic feature. The judge is no longer perceived as an authority that dictates a binding solution of the case to the parties. He or she cooperates with the parties to find and co-create the law to be applied. Discourse theory also stresses the claim to the equal position of parties. According to the contradictory principle, all parties have the same possibility to defend their statements and points of view. The parties and the judge thus create a discourse community in which they argue about the disputed subject and its legal solution. The ideal of the legal discourse theory is to render...

La Pologne est un ancien État communiste qui a signé la Convention européenne des droits de l'homme en 1991 et l'a ratifiée en 1993. Le droit de recours individuel a été reconnu en 1993. Le changement de régime a exigé de revoir le système juridique polonais, dont les principes du procès équitable, afin de pouvoir se conformer aux exigences de la Convention. La France a signé la Convention en 1950, l'a ratifiée en 1974. Le droit de recours individuel a été reconnu en 1981. C'est un des plus anciens signataires de la Convention et actuellement un acteur majeur de la société internationale dont l'attachement aux droits de l'homme constitue un élément caractéristique de sa politique extérieure. Cette étude comparative détermine si les exigences concernant les tribunaux et le procès, ainsi que les droits garantis en matière pénale, imposés par l'article 6 de la Convention, sont respectés dans les deux États. D'un côté, cela permet de voir les différences et les similitudes entre la France et la Pologne qui peuvent sembler différentes à cause de leur histoire et de leur tradition de respect des droits de l'homme, mais qui également se ressemblent dans les mécanismes de protection des droits de l'homme mis en place et rencontrent les problèmes similaires, comme par exemple la durée excessive de la procédure ou le non-Respect du principe de l'égalité des armes.D'un autre côté, cela permet de vérifier si les organes internes ont bien appliqué et, le cas échéant, réparé les violations de la Convention, notamment par les réformes de la loi interne. / Poland is a post-Communist state which signed the Convention in 1991, and ratified it in 1993. The right to the individual application was established in 1993. The change of the regime required to reform the Polish legal system, including the principles of fair trial, to comply with the requirements of the Convention. France signed the Convention in 1950, and ratified it in 1974. The right to the individual application was established in 1981. It is one of the oldest members of the Convention and at the moment one of the major actors of the international society, whose attachment to human rights is one of the characteristics of its foreign policy. This comparative study sets out to determine whether the requirements concerning the courts and the trials, and the rights guaranteed in criminal matters imposed by the article 6 of the Convention are respected in both states. On the one hand, this enables us to see the differences and the similitudes between France and Poland. These two states can seem to be different because of their respective histories and traditions when it comes to the respect of human rights. However, in the final analysis, they deal with similar problems, as, for example, the excessive length of proceedings, or non-Respect of the principle of equity of arms. On the other hand, this enables us to verify if the judgements of the European Court of Human Rights have been entirely implemented by the two states, and, where necessary, if the infringements of the Convention were repaired, including the reforms of the internal law.
