This article presents an overview and extension of research into one form of diversionary justice, the Youth Justice Conferencing programme in New South Wales, Australia. Conferences are formal procedures organised by a Convenor and typically involving a young offender, their victim or victim’s representative, support persons, the arresting police officer, a police liaison officer and additional community members. After a recount of the offence, its ramifications are discussed and an appropriate community service outcome plan agreed upon. The research explored this restorative justice programme from the perspectives of functional linguistics and performance studies, combining close textual analysis with ethnographic research methodologies. We focus on the dialectic of theory and practice enacted in this research, highlighting some of the results of our enquiries and reflecting on the ways it stimulated development of our theory, descriptions and representations. This work is then extended in relation to the negotiation of an apology by the young offender to their victim in conference interaction.
