The Victorian youth justice advocacy coalition, Smart Justice for Young People (SJ4YP), has published a report aimed at strengthening the understanding of a justice reinvestment approach and exploring how it might be implemented in Victoria. Justice reinvestment is an approach to the criminal justice system that redirects funding away from incarcerating people in youth detention and towards community-based initiatives aimed at addressing the root causes of crime. This report looks at case studies of justice reinvestment in the US, New Zealand and Europe.
