Abstract: The many new parties in Indonesia caused a lot of conflicts and divisions. New politicians color the political arena in Indonesia, who generally lack experience, resulting in conflicts between politicians and with other parties, especially in new parties that have recently been formed. Although conflicts also occur in parties that have existed for a long time. Therefore, the purpose of this research is to analyze and find the resolution of internal disputes of political parties in Indonesia by party courts as well as constraints on the authority of party courts in resolving internal disputes of political parties based on the value of justice.
