Longtemps, en matière de protection effective des droits et libertés fondamentaux des administrés, le juge administratif a été relégué au second plan, derrière son homologue judiciaire, en raison d’une inefficacité chronique de ses procédures d’urgence. Le législateur a cependant remédié à cette défaillance en créant, notamment, le référé-liberté dont l’objectif avoué était de faire du juge administratif un véritable juge des libertés, au même titre que le juge judiciaire de la voie de fait administrative. En dix années d’application, le juge administratif a su pleinement se saisir de l’opportunité qui lui a ainsi été donnée de concurrencer le juge judiciaire par une politique jurisprudentielle évolutive et constructive. Cette politique s’est traduite par une conception très extensive de la notion de « libertés fondamentales », et par l’avènement de véritables mesures injonctives au service de celles-ci. L’étendue des libertés jugées comme fondamentales et celle du degré de leur protection vont indéniablement dans le sens de l’accession du juge administratif des référés au rang de protecteur effectif des droits et libertés fondamentaux des administrés. / Regarding citizens’ effective protection in terms of fundamental rights and liberties, the administrative judge has, for a long time, been overshadowed by his judicial counterpart, because of a chronic ineffectiveness concerning urgency procedures. However, lawmakers have redressed that situation in particular by creating the “freedom summary procedure” which explicitly aimed at transforming the administrative judge into an actual custodial judge in the same way the judicial judge is for illegal administrative acts. In the ten years following that creation, the administrative judge has fully seized the opportunity to compete with the judicial judge thanks to a progressive and constructive judicial policy. This policy resulted in a significantly extended conception of the notion of “fundamental liberties” and in the appearance and development of injunctive actions to protect them. The range of liberties considered as fundamental as well as the consequent degree of their protection will undeniably serve the aim of a rise of the administrative judge to the rank of effective protector of the citizens’ fundamental rights and liberties.

The thesis deals with the question about necessary conditions to achieve the objective of a high level of consumer protection in the context of the ongoing internal electricity market taking into account the grid-bound electricity supply, which is characterized by the natural monopoly of regulated networks as well as by competition for the homogeneous product electricity. It evaluates the relationship between effective competition and energy sector-specific consumer protection taking into account the energy-specific regulatory law and examines in detail the regulations of the Directive 2009/72/EC concerning consumer protection under the perspective of enabling the responsible and informed consumer to operate as a self-determined market participant and so shape the market actively towards its completion. After art. 114 TFEU as the existing central norm concerning the alignment of the internal energy market is distinguished from other possible competence rules like the new energy sector-specific competence title of art. 194 TFEU the requirements developed by the ECJ case law concerning art. 114 TFEU from the point of view of the energy sector-specific consumer protection are presented. The thesis clarifies both to what extent in Directive 2009/72/EC codified consumer rights are suitable to achieve...
