The main question is whether the KSP established by Presidential Regulation Number 26 of 2015 contradicts the constitutional system? By using the doctrinal method, this article concludes that the establishment of KSP is unconstitutional because the jurisdiction of the KSP overlaps with that of other institutions, which according to Indonesia’s 1945 Constitution and some statutes have to assist the President such as the Vice President, Ministers, and the Presidential Advisory Council. The position of the KSP must be changed to a ministry so that it can perform governmental functions, namely, the enhancement, coordination, and synchronization of government programs. Keywords: The Executive Office of the President, Indonesian Constitutional System, Presidential Supporting System. INTRODUCTION As one of the President's supporting institutions, the Executive Office of the President (Kantor Staf Presiden or KSP) raises several Indonesian constitutional government issues. This is because the KSP, formed by Presidential Regulation (Peraturan Presiden or Press) Number 26 of 2015 on the Office of the Presidential Staff (Press 26/2015), has powers that overlap with other institutions whose duties are also to support the President’s work such as the Presidential Advisory Council (Dewan Pertimbangan Presiden or Wantimpres) and the Vice President. More is at stake because many of these institutions with overlapping powers with the KSP are established by rules whose position is higher than Press 26/2015 in the Indonesian legal hierarchy, such as the 1945 Constitution and the Statutes (Cases, 2015). In substance, the power of the KSP in the Press 26/2015 can be classified into two groups. First is the authority to control, resolve, accelerate and monitor national priority programs. Second is the authority to submit data analysis and strategic information to support the decision-making process. Those two powers are very likely to collide with the authority of the ministers as the President’s assistants since Article 17 of the 1945 Constitution states that the ministers assist the President, elaborated further in Law No. 39 (Law, 2008) on the Government Ministry (the Law of Ministry) that mentions various kinds of government affairs as the basis to forming a ministry office. Each of these ministries is indeed implementing national priority
