L’usage de la force en droit international a connu d’importantes évolutions au XXème siècle. Après la seconde guerre mondiale le droit à la guerre devient un droit d’exception et l’usage de la force est prohibé hors du cadre strict mis en place par le système des Nations Unies. Cependant l’époque récente voit ressurgir d’anciens concepts comme celui de « guerre juste » ou « d’intervention d’humanité ». Si la guerre n’est désormais plus acceptée dans ses formes anciennes, l’intervention et l’usage de la force armée demeurent des options dans le paysage international contemporain. Au cœur de la question de l’usage de la force se trouve celle de sa justification. Les nouveaux concepts en la matière puisent pour beaucoup dans des justifications humanitaires. C’est dans cette lignée que la rhétorique de l’usage de la force pour contrer des situations enfreignant les droits des femmes s’inscrit. Nous nous intéressons donc ici à l’intersection de la question de l’usage de la force et des femmes, que les résolutions « Femmes Paix et Sécurité » représentent. Après avoir abordé l’évolution, les pratiques et concepts actuels de l’usage de la force, nous aborderons différentes positions féministes sur le sujet qui offrirons un cadre théorique à l’analyse qualitative thématique des résolutions « Femmes Paix et Sécurité ». / The use of force in international law has greatly evolved since World War II. The use of force is now an exception, reduced within the strict framework established by the United Nations, and specifically under the control of the Security Council. And yet, the latest decades have witnessed old concepts coming back to life. Such as the « just war » and the « humanitarian intervention ». War no longer beeing acceptable means it has to be justified. The quore of those justifications are of humanitarian basis. It is in this context that the rethoric of the use of force to save women has developped. The Council’s «Women, Peace and Security » resolutions are found to be an interesting intersection for this subject. After presenting its historical context, the present regime on the use of force and its recent tensions will be highlighted. Concepts from different feminist school of thoughts will then be presented to provide a theorical framework for the analysis of the resolutions that will close this paper.

国境衝突事件において、そこで用いられる"use of force"が法執行活動の実力行使なのか、国連憲章2条4項の意味における武力の行使なのかに注目し、その接際部付近にある判例及び国家実行を分析した論文である。 / The principal aim of this thesis is that while noting they should distinguish ones of LAW ENFORCEMENT and ones of THE USE OF FORCE REFERED TO THE UN CHARTER to use a "use of force" in frontier incidents, it is to analysis jurisprudence and state practices near the connection between the two concepts. / 博士(法学) / Doctor of Laws / 同志社大学 / Doshisha University

<p><br></p> <p>Police use of force has become a topic of significant concern, particularly given the disparate impact on communities of color. Research has shown that police officer involved shootings, misconduct and excessive use of force complaints exhibit network effects, where officers are at greater risk of being involved in these incidents when they socialize with officers who have a history of use of force and misconduct. Given that use of force and misconduct behavior appear to be transmissible across police networks, we are attempting to address if police networks can be altered to reduce use of force and misconduct events in a limited scope.</p> <p><br></p> <p>In this work, we analyze a novel dataset from the Indianapolis Metropolitan Police Department on officer field training, subsequent use of force, and the role of network effects from field training officers. We construct a network survival model for analyzing time-to-event of use of force incidents involving new police trainees. The model includes network effects of the diffusion of risk from field training officers (FTOs) to trainees. We then introduce a network rewiring algorithm to maximize the expected time to use of force events upon completion of field training. We study several versions of the algorithm, including constraints that encourage demographic diversity of FTOs. The results show that FTO use of force history is the best predictor of trainee's time to use of force in the survival model and rewiring the network can increase the expected time (in days) of a recruit's first use of force incident by 8%. </p> <p>We then discuss the potential benefits and challenges associated with implementing such an algorithm in practice.</p> <p><br></p>

La criminalisation de l’agression et l’établissement de la compétence de la Cour pénale internationale sur ce crime obligent à donner une définition de ce crime, de même qu’à déterminer les conditions dans lesquelles la Cour exercera sa compétence sur ce crime. Cette tâche n’est cependant pas aisée en raison de la « nature particulière » du crime d’agression. Le problème majeur qui se pose est celui de la difficulté à définir et à encadrer le crime d’agression tout en respectant les règles cardinales du droit international pénal d’un côté et les exigences du droit de la Charte ou du droit international du maintien de la paix de l’autre côté.En raison de la nature juridique de l’agression et plus précisément du positionnement atypique qui caractérise le crime d’agression, crime à la croisée du droit international du maintien de la paix et du droit international pénal, sans oublier le fait que ce crime vise exclusivement les personnes « effectivement en mesure de contrôler ou de diriger l’action politique ou militaire d’un État », le régime juridique du crime d’agression va être assez particulier, ceci en comparaison de celui des autres crimes internationaux contenus dans le Statut de Rome. / The criminalization of aggression and the establishment of the International Criminal Court’s jurisdiction over this crime make it necessary to provide a definition for this crime, and to determine the conditions under which the Court shall exercise its jurisdiction over this crime. However, this task is not an easy one given the ‘’particular nature’’ of the crime of aggression. The major challenge we are faced with lies in the difficulty to define and circumscribe the crime of aggression while abiding by the cardinal rules of international criminal law on the one hand, and the requirements of the law of the Charter or the law of the international Peacekeeping on the other. Due to the legal nature of the aggression, more precisely the atypical positioning characteristic of the crime of aggression, a crime which is halfway between the law of the international peacekeeping and the international criminal law, not forgetting the fact that this crime targets exclusively individuals who are ‘’ actually able to control or lead the political or military action of a State,’’ the legal regime of the crime of aggression is going to be fairly peculiar, in comparison with that of the other international crimes provided for by the Rome Statute

The main purpose of this work is to investigate if the US ́s killing of Osama bin Laden on 2 May 2011 in Abbottabad in Pakistan was lawful. The background to the killing is what happened on 11 September 2001 when four US airplanes were hijacked and crashed into World Trade Center and Pentagon. Al Qaeda, a terrorist organisation led by Osama bin Laden, was immediately suspected for the attacks, which led to the starting point of the US ́s ‘global war on terror’. This work tries to give a short brief on ‘global war on terror’ and answer if there is a global war on terror and/or if a new category of war is needed. In order to get an answer to the main question of this work I had to investigate if US is in an international armed conflict or in a non-international armed conflict with Al Qaida. Another important question to investigate is if an armed conflict in one State can spill over to another State and still be consider as an armed conflict. Other important questions to answer are, if Osama bin Laden was a legitimate target under international humanitarian law, if he was a civilian or if he had a continuous combat function and what level of participation in hostilities he had? Not less important is also to investigate if human rights law is applicable when Osama bin Laden was killed, especially the fundamental right to life. Lastly I end my investigation with a quick review of the laws of jus ad bellum in order to get an answer if US had a right to resort to force in Pakistan. My conclusion is that the US was not involved in an armed conflict with al Qaeda in Pakistan where the killing took place. The conflict between the US and al Qaeda in Afghanistan is to be categorised as a non-international conflict. This conflict cannot be described as a conflict that has spilled over to Abbottabad where Osama bin Laden was killed. All people, including Osama bin Laden, has a right to life. Because of lack of information on what happened in Abbottabad when Osama bin Laden was killed it is impossible to give a clear legal answer if the US had the right to kill him. It could be lawful, but it could also be considered as a crime against international human rights law.

Le crime d'agression se veut etre un des quatre crimes internationaux sous la juridiction de la CPI. Lorsque les delegues a la Conference de Rome n'eurent point atteint de consensus sur une definition du crime, celui-ci resta, depuis, indefini en droit. En consequence, la CPI n'aura juridiction pour entendre des causes portant sur le crime d'agression qu'une fois la definition sera adoptee par l'Assemblee des Etats Parties au plus tot en 2009. Ce memoire traite trois problematiques liees au crime d'agression : la question de la responsabilite penale individuelle, le role du Conseil de securite de l'ONU, et les parametres du crime en tant que tel. La responsabilite penale individuelle est analysee, inter alia, du point de vue du principe des sources du droit international. Quant al'eventuelle implication du Conseil de securite dans le champ de competence de la CPI sur le crime d'agression, l'auteure soutient tel que suit: Si le Conseil de securite se voit accorde un pouvoir plus large que celui dont il est presentement dote en vertu des articles 13(b) et 16 du Statut de Rome, chaque membre permanent aura un veto sur toute situation d'agression qui serait autrement portee devant la Cour. Ceci aura pour consequence de politiser la CPI en ce qui a trait au crime et rendra hypothethique toute definition eventuelle. Si la definition est bien con9ue et redigee, on fait valoir, qu'il n' est point necessaire de limiter davantage la competence de la CPI. Les parametres de la definition du crime proposes par l'auteure sont etablis selon les conclusions d'une analyse des notions composantes de l'agression. L'essentiel du concept se veut un recours illegal et non-necessaire qui constitue une rupture ala paix. Amoins qu'il ne soit exerce en « legitime defence» ou en vertu d'un mandat du Chapitre VII, Ie recours ala force constitue prima facie une agression et s'il est suffisamment grave, il s'agira d'un crime d'agression. Ce memoire termine avec un projet de definition du crime d'agression en vue d'avancer Ie discours vers un consensus sur ces problematiques majeures. Non seulement est-il possible d'arriver aun consensus sur la definition, croit l'auteure, mais nous sommes plus que jamais al'aube d'y parvenir. / The crime of aggression is one of the four international crimes under the jurisdiction of the ICC. When delegates at the Rome Conference were unable to agree on the content of a definition, the crime was left undefined. As a result, the ICC can only begin prosecuting individuals for the crime of aggression once a definition is adopted by the Assembly of States Parties in 2009, at the earliest. This thesis examines three issues associated with the crime of aggression: the question of individual criminal responsibility, the role of the UN Security Council and the general scope of the definition of the crime of aggression itself Individual criminal liability is reviewed, inter alia, from the perspective of international sources doctrine. Regarding the role of the Security Council in relation to the crime of aggression, the author concludes: if the Security Council is vested with more powers than it already has under Articles 13(b) and 16 of the Rome Statute, each permanent member will have a veto over any situation of aggression that might otherwise be brought before the Court. This would result in a complete politicization of the ICC and render moot any future definition of the crime of aggression. If a definition for the crime of aggression is properly conceived and constructed, it is argued, there is no need to further limit the Court's exercise of jurisdiction. The author proposes general parameters for the scope ofthe definition based on conclusions reached in the analysis of the conceptual components of aggression. At its essence, the act of aggression is the unnecessary, unlawful use of force which constitutes a breach ofthe peace. Unless employed in "self-defence" or under a Chapter VII mandate, the use offorce constitutes prima facie an act of aggression, and if it is sufficiently grave, a crime ofaggression. This thesis concludes with a working definition ofthe crime of aggression to promote dialogue and ultimately a consensus on these core issues. Not only is a definition is within reach, the author believes, we are closer to it than we ever have been before. / "Mémoire présenté à la Faculté des Études supérieures en vue de l'obtention du grade de LL.M. en Maîtrise en droit Option recherche"

Armed conflict and violence against civilians in the Democratic Republic of the Congo has persisted for years starting in the 1990s. The Eastern, Western and North-Eastern parts of the country have seen the presence of a multiplicity of armed groups that have caused an escalation of the humanitarian crisis. The United Nations, in the interest of civilian protection, peacekeeping and security sector reform in the Democratic Republic of the Congo declared a mission under The United Nations Organisational Mission in the Democratic Republic of the Congo (MONUC). In spite of this mission, civilians continued in the Congo to suffer attacks and to endure human rights abuses by the armed militants that are fighting government and the government forces in shape of the Armed Forces of the Democratic Republic of the Congo (FARDC). This study examines the problematique of the mandate of MONUC in the Democratic Republic of the Congo in light of the challenges that have made its success debatable. The success of MONUC has become debatable in light of the fact that in spite of its presence and implementation in the DRC, between 2007 and 2010, conflict and the violence against civilians escalated to unprecedented levels. This study examines the causalities of the failure and observes its effect while making propositions towards amelioration of the challenges and the failure of the United Nations Mission in the Democratic Republic of the Congo. / Political Sciences / M.A. (International Politics)

Iraq, 2003 : une coalition menée par les États-Unis et le Royaume-Uni engagea une action militaire juridiquement fondée sur une autorisation de recourir à la force implicitement contenue dans la résolution 1441 (2002) du Conseil de sécurité. Ce fondement fut également mis en avant au Kosovo (1999) ou encore au Liberia (1992).Ces trois cas illustrent l'application d'une pratique qualifiée d'autorisation implicite en matière de recours à la force. Alors que l'autorisation de recourir à la force doit résulter d'une mention explicite du Conseil de sécurité, l'autorisation implicite repose sur une interprétation entre les lignes des résolutions du Conseil afin d'y mettre en évidence une telle autorisation. Les États qui y recourent n'ont guère manqué de préciser qu'un précédent ne saurait se révéler de cette pratique en marge de la légalité internationale. Malgré son caractère controversé, ce moyen juridique tend cependant à devenir le support privilégié des États en l'absence d'une autorisation explicite.D'où, un paradoxe de l'autorisation implicite dont il nous reviendra d'en évaluer la légalité en examinant les modalités de son élaboration et de son application. Les difficultés à trancher la question de sa validité en droit international nous amèneront notamment à dépasser ce standard de légalité pour lui substituer celui de conformité, plus souple, dans un cadre juridique original : la légalité d'exception. Nous verrons enfin que l'approche téléologique de l'autorisation implicite souffre de lacunes substantielles au point de réaffirmer la double exigence du mandat clair ainsi que du contrôle des résolutions du Conseil de sécurité autorisant le recours à la force. / Iraq 2003: a coalition led by the United States and the United Kingdom undertook military action based on a legal authorization to use force implicitly contained in Security Council Resolution 1441 (2002). This argument was also highlighted in Kosovo (1999), and Liberia (1992).These three cases illustrate the application of a practice known as the implied authorization for use of force. While the authorization for use of military force must result from explicit Security Council Resolution, the implied authorization is based on an interprÉtation between the lines of Security Council Resolutions in order to highlight such an authorization. The States that had recourse to it made it abundantly clear that a precedent cannot result of this practice on the sidelines of international legality. However, despite its controversial nature, it tends to become the privileged support of the State in the absence of an explicit authorization.Hence a paradox of the implied authorization which we will assess the legality, by examining the modalities of its elaboration and its application. The difficulties by resolving the question of its validity under international law will lead us to overcome this particular standard of legality by substituting it for that of conformity, more flexible, in an original legal framework: the legality of exception. We shall finally see that the teleological approach of the implied authorization suffers substantial gaps so that we will reaffirm the dual requirement of the clear mandate and the control within the Security Council Resolutions authorizing use of force.
