The right to access information on judicial institutions is an integral part of the constitutional rights that guaranteed by the Indonesian Constitution and must be fulfilled. The question proposed in this paper is how far the court decisions publication and judicial reform based on electronic courts implicated to increase public trust to judicial institutions in Indonesia? On the one hand, public information disclosure is a demand for democracy, transparency, and accountability of judicial institutions to gain the public trust. On the other hand, the level of public trust to the judicial institution is still low. The research objective is to provide a general description the judicial information system services based on electronic court through the Supreme Court Decisions Directory and its implication to increase the public trust to the judicial institutions in Indonesia.

The evidence can be seen in the decision-making filing program in the last ten years, in which the Indonesian Supreme Court has also succeeded in publishing 4,661,021 court decisions, consisting of 4,403,428 at first-level court decisions, 123,995 at appellate court decisions, 100,863 at verdict decisions, and 32,735 at reconsi¬deration decisions.
