Cette étude se livre à l’analyse de la faculté de "dépeçage" du contrat dont disposent les parties à un contrat international afin de le soumettre à différents systèmes de règles. Permise par le principe d’autonomie de la volonté, cette figure a été consacrée par la Convention de Rome, devenue règlement Rome I, qui constitue le droit international privé français et européen en matière contractuelle. L’intérêt de cette technique a ensuite été renouvelé par la Proposition de règlement Rome 1 dont la nouveauté réside dans l'admission de la combinaison non seulement entre différentes lois étatiques comme c'est le cas actuellement, mais également entre des lois étatiques avec des lois a-étatiques. A cet égard, les contours théorique du terme sont explorés. Le droit des contrats étant avant tout un droit pratique, cette étude se propose d’évaluer l'intérêt réel de la mesure envisagée pour les opérateurs du commerce international. L’intérêt de la démonstration repose notamment sur la méthodologie de recherche employée, la question du dépeçage du contrat étant étudiée tant sur un plan théorique que précisée sur le plan pratique. / This study aims at analyzing contractual “dépeçage” or “contractual splitting”. This ability allow the parties to an international contract to distribute it between different laws. The figure has been enshrined in the Rome Convention, that became the Rome I Regulation, which now constitutes the actual French and European private international law of contract. The advantage of this technique was then renewed by the Proposal for a Regulation Rome 1 whose novelty lies in the admission of the combination, not only between different state laws as it is currently the case, but also, between state laws and non-state laws. In this respect, the theoretical contours of the term are explored. And since contract law is primarily a practical law, this study aims to assess the real value of the measure for international operators. The interest of the demonstration is therefore based on the methodology of the research, the issue split the contract being discussed both on a theoretical level, as on a practical point of view.

La part spécifique prise par certains fidèles laïcs dans la vie et la mission de l'Église requiert l'élaboration d'outils conceptuels permettant d'en rendre compte. Parmi ceux -ci, la notion de participation est souvent mise en oeuvre, notamment dans l'expression "participation à l'exercice de la charge pastorale". Le faible investissement de la théologie dans 1 analyse de la notion de participation et le contexte de crise dans lequel elle est utilisée entraînent un flou institutionnel qui invite à un travail théologique d'analyse et d'évaluation. Le point de départ de cette recherche est constituée par le c. 517 ʹ 2, seule source disponible par sa proposition de confier une "participation à l'exercice de la charge pastorale de la paroisse" à certains fidèles. L'évaluation théologique de cette participation appelle un travail généalogique à trois niveaux. Elle passe par l'histoire de la rédaction du c. 517 ʹ 2 afin de comprendre la volonté du Législateur. Elle nécessite une recherche lexicologique dans le Code de 1983 et dans les Actes de Vatican II afin de poser les bases d'une définition de la notion de participation. Elle demande une enquête historique sur l'usage de la notion de participation dans l'Église au XXe s. : dans le cadre du Mouvement liturgique ("participation des fidèles à la liturgie") et de l'Action catholique ("participation du laïcat à l'apostolat de la Hiérarchie"). Au terme, deux valeurs de la notion de participation peuvent être mises à jour: une participation mystérique à la vie et à la mission que l'Église reçoit du Christ et une participation partitive de quelques fidèles à la mission des pasteurs. Ces deux valeurs appartiennent à deux perspectives ecclésiologiques différentes, charismatique et sociétaire. Ce résultat permet une évaluation des équilibres théologiques du c.517ʹ2 et met en évidence ses limites ecclésiologiques. Il permet également des propositions concrètes pour reconnaître aux communautés chrétiennes leur statut de sujets d'action, d'initiative et de droit.

The criminal justice as well as the persons participating in criminal proceedings, they both are currently facing number of newly posed challenges and unanswered questions so far, due to the onward going integration of the European Union and much closer cooperation of the Member States, in the field of the Procedural Criminal Law. There have been established many new institutions within the field of the European Union in last few years and there were adopted many legal tools which directly influence the cooperation between the judicial and police authorities of individual countries. In connection with newly emerging forms of the crime and more coherent cooperation of the perpetrators of severe crime, the relevant authorities at the union level as well as at the national level encounter situations not being resolved at all, or which are specified by theoretical standards only and have not been put into practice yet. Due to the diversity and abundance of the legal tools and institutions which interfere the criminal law sphere without adjusting their mutual cooperation or without having sorted out the priority of application in many cases, the author of this thesis considers as an appropriate to have such comprehensive view to this relevant issue introduced to the specialized public, as well as having...

Magister Legum - LLM / Even though sexual violence has always been a part and parcel of conflicts and atrocities throughout the ages, it never found any interpretation by subsequent tribunals who were responsible for prosecuting offenders.The case of The Prosecutor v Jean-Paul Akayesu was the first of its kind to give jurisprudential recognition and interpretation to sexual violence as war crimes, crimes against humanity and genocide respectively. This case was important for the following reasons:1. It acknowledged that sexual violence can amount to an act of genocide; 2. It acknowledged that sexual violence can amount to a crime against humanity; and 3. It was the first case to define rape within an international context.Following the case of The Prosecutor v Jean-Paul Akayesu many tribunals gave recognition to the extent of which sexual violence takes place during atrocities by correctly convicting accused for either participating in sexual violence or aiding and abetting to sexual violence. Amidst the various interpretations on what constitutes sexual violence and how it is defined, the International Criminal Tribunal for the former Yugoslavia, the International Criminal Tribunal for Rwanda and the Special Court for Sierra Leone all either conceptualised sexual violence as genocide, war crimes or/ and crimes against humanity.At the same time, the development of sexual violence as either a crime against humanity or a war crime did not end with the courts. The case of The Prosecutor v Jean-Paul Akayesu sparked a fire in the international community, which led to it paying more attention to the place of sexual violence in treaty law. Taking into account that rape is listed as a crime against humanity in both the International Criminal Tribunal for the former Yugoslavia and the International Criminal Tribunal for Rwanda statutes, the Special Court for Sierra Leone and the International Criminal Court statutes both list more than one form of sexual violence as a crime against humanity. It is interesting to note that the latter two treaty developments took place only after the International Criminal Tribunal conceptualised sexual violence as a crime against humanity.Thus apart from merely listing rape as a crime against humanity, the Statute establishing the Special Court for Sierra Leone, states in article 2(g) that sexual slavery, enforced prostitution, forced pregnancy and any other form of sexual violence constitutes a crime against humanity. The Statute establishing the International Criminal Court states in article 7(1)(g) that rape, sexual slavery, enforced prostitution, forced pregnancy, enforced sterilisation or any other form of sexual violence of comparable gravity constitutes a crime against humanity. The interpretation of these acts is further guided by the ‘Elements of Crimes’ which are annexed to the International Criminal Court statute.Once again it is interesting to note that the ‘Elements of Crimes’ for these acts are similar to how the International Criminal Tribunals (both the former Yugoslavia and Rwanda tribunals) conceptualised various acts of sexual violence.On the other hand, the definition of genocide remained the same as it was defined in the Convention on the Prevention and Punishment of the Crime of Genocide of 1948. This definition does not expressly mention any form of sexual violence as a form of genocide.However, once again, the trial chamber in the case of The Prosecutor v Jean-Paul Akayesu set the benchmark for sexual violence to constitute a form of genocide by way of interpretation. The definition of genocide did not subsequently change in the Statute establishing the International Criminal Court.Based on these premises, this thesis attempts to investigate the similarities and differences in sexual violence as a form of both genocide and a crime against humanity,by addressing the following question:What are the essential and practical differences between sexual violence as crimes against humanity and genocide and what is the legal effect of the differences, should there be any? Chapter 1 highlights the historical overview and developments of sexual violence as genocide and crimes against humanity, while chapter 2 investigates how sexual violence can amount to a form of genocide. Chapter 3 assesses the advances made in sexual violence as a crime against humanity, while chapter 4 importantly draws a comparative analysis between sexual violence as genocide and a crime against humanity. Chapter 4 draws this comparison by weighing up four differences and four similarities in sexual violence as genocide and a crime against humanity.Chapter 5 highlights the conclusion and provides an answer for the research question that is posed above. Here it is concluded that even though there exist multiple differences in sexual violence as crimes against humanity and genocide, there are also multiple similarities which could possibly amount to a better chance for conviction of an accused under a crime against humanity than genocide. Chapter 5 also provide possible recommendations for the consequences that might flow should sexual violence as a crime against humanity be fairly similar to sexual violence as genocide.

The thesis examines the international law pertaining to the use of force by states, in general, and to the use of force in self-defence, in particular. The main question addressed is whether the use of force, which was purported to be in self-defence, by the United States, the United Kingdom and their allies against al Qaeda, the Taliban and Afghanistan, beginning on 7 October 2001, was lawful. The thesis focuses not only on this specific use of force, but also on the changing nature of conflict, the definition of terrorism and on the historical evolution of limitations on the use of force, from antiquity until 2006. In the six chapters which trace the epochs of international law, the progression of five inter-related concepts is followed: limitations on the resort to force generally, the use of force in self-defence, pre-emptive self-defence, the use of forcible measures short of war, and the use of force in response to non-state actors. This historical analysis includes a particular emphasis on understanding the meaning of the 'inherent right of self-defence', which was preserved by Article 51 of the United Nations' Charter. This analysis is then applied to the use of force against Afghanistan which occurred in 2001. Following the terrorist attacks of 11 September, the US and the UK notified the United Nations Security Council of their resort to force in self-defence under Article 51. Each element of Article 51 is analysed and the thesis concludes that there are significant doubts as to the lawfulness of that decision to employ force. In addition to the self-defence justification, other possible grounds for intervention are also examined, such as humanitarian intervention, Security Council authorisation and intervention by invitation. This thesis challenges the common assumption that the use of force against Afghanistan was an example of states exercising their inherent right to self-defence. It argues that if this particular use of force is not challenged, it will lead to an expansion of the right of self-defence which will hinder rather than enhance international peace and security. Finally, this thesis draws on recent examples to illustrate the point that the use of force against Afghanistan could become a dangerous precedent for the use of force in self-defence.
