The authority granted, by the 2017 constitutional amendment, to the President to make the primary regulations through presidential decrees (executive orders) should not be considered as one of the important problems of the new system. Thus, it is a practical necessity to entrust the executive with the authority to introduce primary regulations, for an effective and efficient administration, not only in the presidential system but also in the parliamentary system, providing that the boundaries and the area of such an authorisation are well defined. The negative aspects of the new system predominantly derive from the relation of the executive with the legislature and especially the judiciary; however, the primary regulatory power granted to the executive should not be seen as one of the important problems of the new system. However, it should by no means be possible to enact a presidential decree on issues prescribed in the Constitution to be regulated only by law, such as the restriction of fundamental rights and freedoms, as well as the regulation of the powers and duties, and supervision, of administrations that must be administratively autonomous, namely local administrations, public professional organizations and universities.
