PurposeThe paper aims to reach a better understanding of accountability and social reporting in the Italian justice system, by examining the state of the art of both literature and practice. The case study highlights the critical elements in drawing up the social report of one of the most important Prosecutor Offices in Italy.Design/methodology/approachThe case study analyzes the activities of the actors involved in the report building process by detailing all the steps involved in a research diary, in order to examine such process from the inside, thus reversing its perspective.FindingsThe study shows that both the lack of guidelines for judicial administrations and a consolidated trend of transforming administrative facts into documents useful to stakeholders slow down the evolution of practices, which are stuck in a perpetual trial stage.Research limitations/implicationsThe limitations are mainly related to the adoption of a single case study, which does not include any comparison with other reporting experiences in the justice sector.Originality/valueThis paper adds evidence to the theoretical debate on social reporting in the justice sector which has so far received the attention of a limited number of scholars. Furthermore, unlike other studies focusing exclusively on the final report while overlooking the process that turns input into output, this research deals with the core of the social reporting process and practices in their development, capturing their most intimate and controversial aspects from the inside.
