In order to achieve public sector reform and more transparent public information disclosure, the Supreme Court of Republic Indonesia developed the Court Case Information System (CCIS). The CCIS are used by the four judicial systems under Supreme Court: General Court, Military Court, State Administration Court, and Religious Court. Although CCIS has developed in 2011, the internal audit conducted in 2015 shows that CCIS only have 40% active users. Moreover, no assessment has been conducted to investigate what factors may play roles in improving users' intention to use CCIS. This study uses quantitative methods using technology-organizationenvironment (TOE) theory and adds individual contexts to investigate factors affecting individual intentions to use CCIS. There are ten variables tested involving 296 respondents and analyzed by using PLS-SEM approach. The results of this study show that top management support, organization regulation, ease of use, usefulness, self-efficacy and social influence are the factors that may help improving users' intention to use CCIS.
