Purpose - To develop a new model of restorative reparation that attempts to capture the dynamic role of shared identity perceptions.Design/methodology/approach - Drawing on recent advances in restorative justice theory (Wenzel, Okimoto, Feather, & Platow, 2008), we explore the theoretical proposition that a greater understanding of the identity relations between victims, offenders, and the groups in which they are embedded is key to understanding a victim's underlying motives toward justice, and thus, predicting when victims will react favorably to restorative justice processes and prefer them over traditional retributive justice interventions. Findings - We argue that a perceived shared identity between the victim and the offender determines the extent to which the victim understands the transgression as requiring a revalidation of the rules, values, or morals undermined by the offense. Moreover, we propose that these identity relations are dynamic in that they both affect and are affected by the experience of injustice. Thus, identity is also shaped by the transgression itself through, inter alia, processes associated with positive social identity maintenance. Importantly, these shifts in identity determine how injustice victims are likely to respond to constructive approaches to conflict resolution such as restorative justice. Originality/value - We offer a series of testable hypotheses aimed at engendering future research in the domain of constructive justice restoration in groups. Moreover, this work suggests that to develop effective resolution strategies, we must consider how an injustice event shapes the relations between the affected parties over time rather than simply assuming identity relations are static.
