The research results show that there are several models of constitutional judge appointments in different countries, namely models involving the executive and legislative branches, models involving only the legislative branch, models involving all three branches of government, and models conducted by special institutions. Indonesia itself uses a model involving all three branches of government. This research also compares the system for appointing constitutional judges in Indonesia with other countries such as Germany, Austria and South Korea. The conclusion of this research is that the mechanism for appointing constitutional judges must be carried out in a transparent, independent and accountable manner in order to guarantee the independence of the Constitutional Court.
