The article authorizes the District Court to implement the decision of the Sharia arbitration body on the resolution of Islamic economic disputes. The article and explanation of the verse contradicts the absolute authority of the Religious Courts regulated in Article 49 letter (i) of the Law on Religious Courts. This shows that, the legislators are not consistent in making laws and regulations, so that it creates legal uncertainty. By applying the normative legal research method to the statute approach and case approach, this article seeks to describe the phenomenon of legal conflicts that occur. From the in-depth analysis it can be concluded that the legal provisions regarding the implementation of the decision of the National Sharia Arbitration Board are regulated in the Arbitration Law, the Judicial Power Act and the Religious Courts Act. The legal substance of the provisions therein enables antinomy or legal conflicts. Antinomy settlement can use the principle of lex specialis derogat legi generali Keywords: legal antinomy, legal conflict, harmonization, legal certainty A. INTRODUCTION The stipulation of Law Number 3 of 2006 concerning Religious Courts has brought great changes to the existence of religious justice institutions today (Manan, 2017). The enactment of this law is a form of government alignments through the direction of its political policies in expanding the authority of the Religious Courts to accommodate the needs of Indonesian people who are predominantly Muslim (Fathurrahman Djamil, 2006). This can be seen in Article 49 letter (i) of the Law on Religious Courts. The amendment from the previous law lies in the absolute competence given to the Religious Courts, which before the authority of the Religious Courts were limited to family law matters (Wahyu Widiana, 2007). Prior to the issuance of the above law, the National Sharia Council of the Indonesian Ulema Council continued to push for the resolution of Islamic economic disputes to be resolved through institutions that possessed human resources who had the qualifications of sharia economic mediation law. These mediators are then assembled in the National Sharia Abitration Agency. This idea was later accommodated as part of the provisions of Bank Indonesia Regulations. This body is a transformation from the previous institution, namely the Muamalat Indonesia Arbitration Board (BAMUI). This abitration body was formed by the Majelis Ulama Indonesia- MUI- (Indonesian Ulema Council) based on MUI Decree No. Kep-09 / MUI XII / 2003 dated December 24, 2003 (Jamaludin, 2019).
