This study aims to examine and analyze the application of the principle of audi et alteram partem in Decision No. 01/Pdt.G.S/2016/PN.Snj. This study uses a normative juridical method with a statute approach. The collection of primary, secondary, and tertiary legal materials is carried out using literature study techniques. The collected legal material is then analyzed using qualitative data analysis methods with a statute approach to describe court decisions and answer study purposes. The results show that the Sinjai District Court has summoned Defendant legally and worthy twice. The summons manifests the Judge’s attitude to apply the principle of audi et alteram partem. In this case, the Judge must listen to both sides before deciding a civil case in court. In contrast, Defendant has not shown good faith, while the Sinjai District Court has summoned Defendant legally and worthy twice. Furthermore, the summons made by the Sinjai District Court also aims to mediate between Plaintiff and Defendant. On the other hand, with the efforts made by the Sinjai District Court, the trial process continues to the evidentiary stage even though the Defendant is not present. The proving process does not eliminate the essence of the audi et alteram partem principle, which is to be listened to by both sides. Therefore, it is recommended to establish new laws and regulations in the legal civil field because there are still laws and regulations that apply in Indonesia, which are a relic of the Dutch colonial era. In addition, the renewal of laws and regulations must pay attention to the audi et alteram partem as one of the principles that require Judges to listen to both sides in civil cases. Furthermore, Supreme Court Regulation No. 4 of 2019, as a basis for resolving civil cases through the procedure for simple lawsuits, should be improved because it is formed not in the Supreme Court Regulation but in a higher hierarchy of laws and regulations.
