摘要:The purpose of this study is to obtain two things,firstly the expansion of the absolute competence of Administrative Court (Hereinafter referred to as PTUN) after the Government Administration Law is promulgated and the implications of the application of the Administrative Law on legal certainty to eradicate and enforce corruption in Indonesia. This study uses a normative juridical research method,and uses a statutory approach (statute approach). The results showed "that there are several forms of expansion of PTUN competencies,such as the authority that acts factually,the authority,administrative authorization,decides on positive fictitious decisions,and discretionary trials". Meanwhile, the implications of the Government Administration Law on corruption are known as corruption crimes,which are true. So,in this context there are at least two problems,namely: “1. If the authorized court case is carried out by the state government which is submitted to the court simultaneously,to the State Administrative Court and to the District Court in a corruption case? 2. If at any time a PTUN decision has been issued stating that it is not authorized,but there is also a party who submits the case to the District Court on charges of corruption. What is the attitude of the District Court,whether to accept the PTUN decision on the case or choose to override the PTUN decision”..
