But unfortunately, not all internal conflicts were ironed out, just as what happened to Persatuan Pembangunan Party. Based on the results of the current study, several factors could be identified to influence the resolution of internal political party disputes, including 1). the inability of the disputed internal party to pay heed to the decision of the Party Court. 2). the government violation of the decision made by the Party Court with biased interference. 3).

Not considering the Party Court's decision while adjudicating disputes over the management of political parties.Keywords: Party Court, Decision, Final.
