In this contribution, the justification of restorative practices in prison is first discussed from a normative perspective. On the basis of Lippke’s retributive theory of imprisonment it is argued that modern, humane retributive sanctioning entails an obligation to provide prisoners with opportunities to engage in restorative practices. Second, restorative practices in prison are examined from the perspective of possible impacts on the empowerment of prisoners and their experience to move away from crime and do good. Finally, it is argued that in order to yield positive effects, restorative practices in prison need to be supported by a safe and healthy living environment.
