This study tries to undertake a thorough study of how legal pluralism in Indonesia that is the result of assimilation of three legal forms (ie customary law, Islamic law and common law law) serves as a basis for enforcing laws for minority communities in Indonesia, particularly in cases Conflict between the BTPs as a minority part of the Muslim community as the majority group in Indonesia. Law and Pluralism are concept that show how a legal validity can be applied to a pluralistic society. In Indonesia, its pluralism is being questioned as minorities like Chinese-descend ethnicity being harassed. This raises question on how is the concept of legal pluralism in Indonesia and How can fairness principles be applied in dealing with conflicts between minorities and the majority in Indonesia. The research is conducted using qualitative approach relying on literature and law review. Research shows that Pluralism is an indisputable fact and is therefore a very important object of study given that justice in law can not only be based only on the positive legal system but also the laws prevailing in society. The existence of the majority and minority groups is something that is certain to happen, and therefore the opposition between the two groups becomes commonplace and should be dealt with fairly so that social justice can be achieved for both groups. This study attempts to deepen discussion of legal pluralism in Indonesia and the legal aspect to achieve social justice for both minority and majority in Indonesia.
