The concept of justice covers a broad spectrum of human existential issues, and is defined according to established relationships that always put the human person as reference. Restorative justice and transitional justice fall into the wide range of attempts to explain and address injustices by seeking accountability, finding adequate sanctions that are proportionate to harm, rehabilitating the offenders, and restoring victims or even reaching an informal negotiated settlement. The authors of this book provide new research in the study of restorative and transitional justice.
