La thèse "L'équilibre institutionnel dans L'Union européenne" vise à reconstruire les développements juridiques et jurisprudentiels qui ont défini l'évolution de l'équilibre au sein de l'Union à partir du début du processus d'intégration. L’approche choisie est double : juridique et politique. Juridique, car il s’agit de déterminer quelles sont les possibilités données par l’ordre juridique communautaire aux institutions pour définir l'équilibre interne sur la base des dispositions des traites. Politique, car cette approche permet de replacer le principe dans son environnement général et de prendre en considération des facteurs de contraintes et des comportements que la logique juridique omet parfois. L'étude a été organisée en deux parties principales, en premier lieu par un examen du cadre institutionnel définie par le Traité sur l' Union européenne puis par une analyse des bases juridiques introduites par la dernière révision des traites, susceptibles d'influencer et modifier les relations interinstitutionnelles dans le domaine de l'adoption des actes juridiques et de l'éxécution des actes de l'Union. / The institutional balance can be envisaged in two different ways. As a principle it has been developed and defined by the Court of justice since Meroni jurisprudence, whilst the practise of the institutions in the implementation of the treaties and the treaty changes concerning the institutional framework and the legal basis governing legislative and budgetary procedures defined the institutional balance as a dynamic concept. The thesis is aimed at analysing the evolution of the institutional balance in the practical sphere and it has been organized in two main parts composed respectively of 2 chapters. The results of the study were that the institutional balance is in a permanent state of evolution and this process didn’t come to an end after the entry in to force of the Lisbon treaty. The institutional innovation failed to eliminate the structural tension which characterized the institutional interaction in the past. Despite the fact that the Lisbon Treaty was adopted after fifteen years of debate and reflection on institutional reforms it was found that the juridical instrument provided in order to implement the inter-institutional cooperation in the Lisbon Treaty are not adequate if one considers the high-level interaction they are required to observe to the scope of achieving the objectives of the Treaty.

The rule-making power of the European Commission, dissertation Mgr. Mgr. Jiří Lenfeld, M.A.; supervisor: doc. JUDr. Richard Král, Ph.D., LL.M. Charles University, Faculty of Law, Department of European Law Prague, March 2013 The aim of the dissertation is to analyse the role of the European Commission in the legislative process of the European Union with the focus on procedures for adoption of legally binding Union acts. The European Commission is one of the main institutions of the European Union. It represents and upholds the interests of the EU as a whole and manages the day-to-day business of implementing EU policies. However, to limit the role of the European Commission to that of an executive body would be misleading. Its role in the EU institutional system is much broader than that. The European Commission is the most important legislator among the EU institutions and is also empowered with an almost exclusive power to submit drafts of EU legal acts. The rule-making power of the European Commission could be seen from two different points of view. In a narrow sense of the word it could be seen as a power conferred on the European Commission by the Treaties to propose drafts and to adopt EU legal acts implementing legally binding Union acts. However, the exercise of the rule-making power may...
