The doctoral thesis deals with the transformation of the state tasks in the field of electricity law, where more and more private persons (compliance officers) are used to fulfill certain public functions, including the implementation of the energy-sectors principle of equal treatment. The concept of regulated self-regulation constitutes the theoretical framework. The development from services of general interest to the states responsibility for fulfillment and responsibility for providing a guarantee is traced in chapter D. In this regard, the dogmatic foundations are discussed and forms and commonalities of regulated self-regulation are examined. In the main chapter of the thesis the aforementioned theoretical framework of the concept of regulated self regulation will be applied on the field of energy law. Here the focus lies on the arrangement of the principle of equal treatment within the field of energy law, including the principle regulatory instruments unbundling and network access. The internal compliance program will be assigned to law, its addressees staked, and subsequently normative substantiated. Using defined terms of the compliance programs the formal frameworks are substantiated. In addition important compliance provisions will be discussed. In the next sub-chapter the legal status of the compliance officer is examined and conditions for exercising his activities are scrutinized, further on his major powers within the energy system operators. Subsequently to show how various state responsibility mechanisms and the energy compliance system work together, to provide the states responsibility functions. The main chapter ends by positioning the compliance officers in the scientific categories of administrative law. The results are summarized at the end in the form of theses.
