Fulfillment of the right to restitution for victims of serious assault crimes in Indonesia is a crucial aspect of the criminal law system that prioritizes restorative justice.

Fulfillment of the right to restitution for victims of serious assault crimes is a concrete manifestation of the value of justice, as contained in the Pancasila Theory of Justice and the principle of the rule of law (rechtstaat).
