The Konrad-Adenauer-Foundation and the Palestinian Center for Independence of the Judiciary and the Legal Profession (MUSAWA) analysed the Palestinian “Checks-and-Balances”-system in a study whose results are published in a book in Arabic. The Palestinian Legislative Council (PLC) represents as a parliament the citizens of the Palestinian Autonomous Territories. As a democratic institution the Council helds the obligation of the legislative power as well as the supervision of the executive. Up to now the PLC was in the shadow of the executive. Corruption and infiltration are the reasons why the Council could not fulfill its role as the controlling organ of the government in a sufficient manner in the past. With the growing reform-euphoria in the Palestinian Territories as background, the Konrad-Adenauer-Foundation decided to support the MUSAWA Institute in publishing a study about the supervision-function of the PLC over the executive. Foremost focus of the study is the exposure of interdependencies between the executive and the legislative not legitimate under the constitution, as well as the analysis of adequate reform plans. In cooperation with political and scientific experts as well as in consideration of several case studies, legal, administrative, technical and political weaknesses could be detected. The study explains the necessary changes to enable the Legislative Council to fulfill better its function as balance weight and controlling organ to the executive. With this in mind the authors have presented a detailed analysis and concrete suggestions.
