From the global pandemic to the Black Lives Matter, the Me Too/Times Up and Indigenous reconciliation and decolonisation movements, the systemic and structural failures of current social institutions around the world have all been brought to our collective consciousness in poignant, painful and urgent ways. The need for fundamental social and systemic transformation is clear. This challenge is central to the work of dealing with the past in countries undergoing transition and in established democracies confronting deep structural inequalities and injustices. Rooted in lessons from the application of restorative justice across these contexts, this article suggests that grounding restorative justice as a relational theory of justice is key to understanding and realising the potential of a restorative approach for transformation. It also explores the implications of this transformative imperative for the growth and development of restorative justice.
