This thesis examines the valuation of transitional justice. It argues the need for and advances a more theoretically expansive set of ideal standards that can be used to assess the process and substantive outcomes of transitional justice decision-making. In so doing, it advocates a victim-inclusive and sustainable model of justice. Effective decision-making is understood in ideal terms as being :(l) politically and publicly inclusive; (2) methodically planned; (3) politically purposive; and (4) legally comprehensive in the sense of equally recognising state obligations and victim rights.

O Direito e o investimento estrangeiro guardam uma relação muito íntima. Sabese que o Direito exerce o papel de induzir ou de reduzir o investimento estrangeiro, tendo em conta o tratamento legal conferido ao receber capital ou bens vindos do exterior. O núcleo central da presente tese é o estrangeiro. Costuma-se estudar a relação de investimento, porém é exatamente sobre a discriminação no tratamento conferido ao investidor estrangeiro que reside o principal papel a ser exercido pelo Direito Internacional do Investimento. Diante desta falha metodológica, a presente tese propõe-se estudar uma nova aproximação metodológica para o Direito Internacional do Investimento, sobretudo para adequar sua análise do contemporâneo Direito Internacional Público e seu princípio da cooperação internacional. Ao final da presente tese, conclui-se que o Direito Internacional do Investimento tem analisado as relações das chamadas Empresas Transnacionais e desconsiderado as pequenas e médias empresas, cuja participação no cenário internacional deve ser incentivada, em especial por meio do associativismo, entre empresas nacionais e estrangeiras. / The law and foreign investment maintain a very close relationship. It is known that the law plays the role of inducing or reducing foreign investment, taking into account the legal treatment given to capital or goods received from abroad. The core of this thesis is the foreigner. It is often study the investment relationship, but it is exactly on discrimination in treatment given to foreign investors that lay the main role to be exercised by international Law Investment. Given this methodological weakness, this thesis proposes to study a new methodological approach to the International Investment Law, mainly to adjust its analysis to contemporary International Law and its principle of international cooperation. At the end of this thesis, it is concluded that the International Investment Law already has explored the relationship of the Transnational Corporations and yet disregarded the small and medium companies, whose involvement in the international arena should be encouraged, in particular through associations, among national and foreign companies.

The content and function of the contribution capacity principle has been a controversial issue for economists and jurists. Through the jurisprudence of the Constitutional Court of Peru, the author claims the capacity of contribution as an implied constitutional principle to award a self-governing function from other principles (legality, equality and non confiscatory) and recognize the outstanding methodological contribution to the Financialand Taxation law unit. / El contenido y función del principio de capacidad contributiva ha sido una cuestión controvertida por economistas y juristas. A través de la jurisprudencia del Tribunal Constitucional de Perú, el autor reivindica la capacidad contributiva como principio constitucional implícito, para adjudicarle una función autónoma de otros principios constitucionales  (legalidad,  igualdad  y  no  confiscatoriedad) y destacar el aporte metodológico a la unidad del derecho financiero y tributario.

A study of silences: as a metaphysics of the law, juridification silences the text of the law in order to enable an allegorical reading of the law. This silencing of the legal text can only be avoided through a non-metaphysical archaeological reading. Similarly, the programme of comparative labour law is silent at its most pivotal points, leaving some concerns of the programme indeterminate and indeterminable. As context, the dominant discourses of the labour law systems of the Federal Republic of Germany (Tarifautonomie), Great Britain (collective laizzesfaire) and South Africa (fairness) are identified and the agents of the jurisprudence (the courts) are briefly outlined. The silence operating within the phenomenology of the labour judiciary and the concept of a 'court' is also examined. The study then proceeds to read, in an archaeological manner, the industrial action jurisprudence in Germany, Great Britain and South Africa, such readings again yielding silences within the discourse of the law. The silences occurring throughout (and the resulting normative breaches in the rationality of the legal discourse) are the prerequisites for juridification, a process in terms of which the metajuridical standard is imported into the legal normative system and thereby rendered part of the archival discourse of the law. / LL.D.
