During the 1990s Yugoslavia and Rwanda were swept by wars accompanied by serious violations of international humanitarian law. Grave and severe crimes wiped away lives and destroyed properties. The United Nations Security Council determined that the violations committed constituted threats to international peace and security, declaring itself empowered to take action. It established international ad hoc criminal tribunals for Yugoslavia and Rwanda with the mandate of prosecuting individuals responsible for those crimes as an enforcement measure under Chapter VII of the United Nations Charter. Investigating the tribunals’ effectiveness enables one to assess whether they achieved the anticipated outcomes based on the tribunals’ mission, goals, and objectives without creating other problems. The research relies on naturalism and positivism to put the tribunals in a moral and ethical perspective. By examining how the tribunals were established, their objectives, the investigation and prosecution processes, the reliance on guilty plea and judicial notice and the imputation of criminal responsibility by applying joint criminal enterprise and command responsibility doctrines; the study argues that prosecution has not been an effective tool as contemplated by the Security Council. An analytical and comparative review of various domestic and international legal resources helped to provide an insightful approach for an effective prosecution of international crimes. Credible, legitimate and legal judicial institutions in which professional judges and prosecutors discharge their function independently, impartially and are accountable may achieve justice for the victims of international crimes. Ad hoc tribunals failed to thoroughly investigate and assume the dual role of prosecution. They conveniently used legal procedural tools that fit petty domestic crimes; unfortunately demeaning the magnitude of international crimes of concern. Criminal responsibility was mostly imputed without properly scrutinising the legality, extent, actual participation and guilty mind of the alleged perpetrators. Effectiveness should be a value assessment. Imposed and overburdened ad hoc tribunals are inappropriate and should be abandoned. / Public, Constitutional, & International / LLD

A cidade de Curitiba já foi tida como sinônimo de vanguarda em desenvolvimento urbano e equilíbrio ecológico. Porém, como na maioria das grandes cidades brasileiras, ela enfrenta problemas sociais, sobretudo, na área da propriedade urbana e da própria preservação ambiental diante das invasões urbanas. Entretanto, a Constituição Federal garantiu aos administradores municipais um elemento essencial para a gestão de suas cidades, o Plano Diretor. Este instrumento, regulamentado pelo Estatuto da Cidade, suscita um planejamento estratégico do município, do seu desenvolvimento e uma maior gestão democrática dos próprios interesses dos cidadãos habitantes da cidade. Esta dissertação de Mestrado tem como objetivo analisar a eficácia jurídica da lei do Plano Diretor de Curitiba 2015 (Lei nº 14.771/2015), no tratamento dado por seus idealizadores (Sociedade, Poder Executivo municipal e Poder Legislativo municipal) à função social da propriedade, sob a perspectiva dos direitos Urbanístico e Ambiental. Por meio de pesquisa em bases de dados acadêmicos, na literatura especializada e na jurisprudência nacional, estabeleceu-se parâmetros para a classificação da eficácia dos ordenamentos contidos no plano diretor de Curitiba em plena (aplicável de imediato), contida (apenas parte pode ser aplicada) e limitado (necessita de uma regulamentação futura para ter eficácia). Entre os principais resultados da pesquisa, tem-se que de 96 artigos da lei do Plano Diretor de Curitiba, diretamente ligados à área do direito urbanístico, direito ambiental e à propriedade, 40% dos mesmos possuem eficácia limitada, 16% dos artigos possuem eficácia contida e 44% possuem a sua eficácia plena. Ou seja, 56% dos artigos, voltados ao tema da pesquisa, não possuem uma aplicabilidade plena de suas diretivas. Isto significa que a lei responsável pelo planejamento do desenvolvimento urbano da cidade, nos próximos 10 anos, não possui eficácia imediata e suficiente para transformar o aspecto nebuloso da distribuição justa e correta da propriedade e de sua função social dentro do território do município de Curitiba. / The city of Curitiba has been regarded as a forefront synonymous of urban development and ecological balance. However, as in most large Brazilian cities, Curitiba faces social problems, especially in the area of urban property and its own environmental preservation facing urban invasions motivated by that. However, the Federal Constitution guaranteed the municipal administrators an essential element for the management of their cities, the Master Plan. This instrument, the Master Plan, which was regulated by the City Statute, provided a strategic planning for the municipality, in its development and a greater democratic management of its own citizens interests, the townspeople. This Master's dissertation aims to analyze the legal force of Curitiba’s Master Plan 2015 (Law No. 14,771 / 2015) in the treatment given by its creators (Society, Municipal Administration and Municipal Legislature) to the social function of property. It was elected as a paradigm for analysis of this work the Urban Law and Environmental Law and their determinations that guide the use, exploitation of urban land and the preservation of the natural and urban environment within the legal orders generated by the approval of the project law update of the master plan of the city of Curitiba. Through research in academic databases, in specific literature and in national jurisprudence, parameters were established for ranking the effectiveness of the orders contained in the full master plan of Curitiba (immediately applicable) contained (only part can be applied) and limited (it needs a future regulation to be effective). The results obtained throughout this work are posted at the end of this paper and they express that from the 96 articles directly related to the urban law area, environmental law and the property contained in the new law of Curitiba’s Master Plan, 40% of them have limited effectiveness, 16% of the articles have contained efficiency and 44% have their full effect, that is, 56% of the articles focused on the theme’s work does not have full applicability of their policies, which imposes thinking to the external observer that the law responsible for the urban development of the city for the next 10 years, at this moment, does not have sufficient efficacy to transform the nebulous aspect of the fair and correct distribution of property and its social function in the municipality of Curitiba.
