Customary Justice System and State Criminal Law: A Model of Reconciliation in Indonesia

Abstract

Indonesia’s legal landscape encompasses over 250 customary justice systems operating alongside the formal state legal framework, serving more than half of the population’s justice needs at the local level. This study examines the development of an adaptive reconciliation model between customary and state criminal justice systems through a comprehensive literature review approach analyzing legal frameworks, academic publications, and empirical studies from five provinces: Aceh, Papua, Bali, West Sumatra, and Central Java. The systematic review analyzed 150 academic articles, 25 legal documents, and 30 case studies published between 2017-2025. The findings reveal that customary justice systems demonstrate significant advantages across five critical dimensions: social impact (community building and reintegration versus stigmatization and isolation), recovery orientation (relationship restoration versus punishment), economic efficiency (rapid, low-cost processes versus expensive, protracted procedures), rehabilitative methods (educational and transformative versus punitive approaches), and imprisonment management (prevention of detention versus prison overcapacity). The customary reconciliation mechanism employs sophisticated approaches through participatory dialogue, symbolic rituals such as peusijuek ceremonies, and continuous social reintegration processes. This research proposes a comprehensive framework for formal recognition of customary court decisions within the national legal system, including specific coordination mechanisms between customary and state courts, development of culturally-sensitive community-based justice programs, and establishment of check and balance mechanisms ensuring human rights protection. The adaptive reconciliation model offers practical solutions for Indonesia’s multicultural society while addressing critical challenges in the formal justice system, including case overload, accessibility barriers, limited rehabilitative outcomes, and prison overcapacity issues.
