This article explores the relationship between justice and child sexual abuse, developing a broader theoretical conception of justice than that customarily applied. The traditional legal perception of justice as the attempted prosecution of alleged perpetrators is widened to encompass justice as initial prevention of abuse, the fair treatment of children by the criminal justice and child protection systems, and the subsequent after-care and compensation of abused children and adults. Concepts of justice are therefore examined within a chronological lifecourse trajectory, as well as being extended from traditional notions of due process and desert to include understandings of justice as human rights, ‘fair shares’ and liberation. Particular social constructions of childhood are revealed to be highly significant regarding how justice is perceived and operationalized. Therefore, the interaction between perceptions of justice and responses to child sexual abuse is examined, relative to wider understandings of childhood.
