Restorative justice seeks to repair the harm done to victims and communities from criminal acts, while also seeking to rehabilitate offenders. It takes four primary forms: victim-offender mediation, family group conferencing, neighborhood reparative boards, and sentencing/peacemaking circles. Evaluations show high levels of participant satisfaction and some evidence of reduced recidivism compared to traditional criminal justice approaches. However, restorative justice faces challenges around its application to serious crimes, procedural safeguards, power imbalances, and the potential for net-widening of social control.
