This paper aims to establish a degree of existence of Hayek’s idea of governmental assembly in the Centre of Government (CoG), which is not only the technical, administrative support for the Prime Minister but has also a regulatory-coordinative, policy role. This paper’s focus is on CoG that is along with the classical tasks of the Prime Minister’s cabinet dedicated to systemic performance. Having this in mind a request was sent by the National Council of the Republic of Slovenia to other parliaments of the EU member states and Switzerland through the ECPRD net to gain information on the effectiveness of national CoGs and/or Prime Minister’s cabinets
