<p>The crisis of retributive justice has exposed the moral limitations of punitive legalism in addressing social harm and human dignity. Indonesia’s search for a more humane justice paradigm requires reinterpreting law as a moral language rather than a coercive apparatus. This study aims to reconstruct justice through the integration of legal semiotics and postcolonial pluralism, positioning <i>Pancasila</i> as a living moral code that mediates between state legality and indigenous ethics. Using a qualitative–normative design grounded in interpretive hermeneutics, the research analyzes cultural practices such as <i>musyawarah</i>, <i>sasi</i>, and <i>pela gandong</i> as semiotic expressions of restorative justice within Indonesia’s plural legal culture. The findings reveal that <i>Restorative Justice Pancasila</i> redefines law as a communicative and participatory process that restores harmony through empathy and dialogue, not punishment. It also demonstrates how postcolonial hybridity can evolve into a decolonial jurisprudence when moral symbols are translated into legal meaning. The study’s originality lies in its theoretical synthesis of semiotics and postcolonial thought to articulate justice as a semiotic–decolonial continuum. This framework contributes to global legal discourse by offering Indonesia’s model of culturally grounded, morally dialogical, and epistemically restorative justice.</p>
