Within-case comparison of the adult and youth justice systems: New directions for a ‘fractured’ penal state?

Building on recent literature on the importance of local grounded comparison and the ‘fracturing’ of the penal state, this article argues that within-case comparison of the adult and youth justice systems can shed important light on the stark differences that persist in how and why we punish. Using the case of Irish youth justice to illustrate the utility of fracturing the penal state horizontally, as well as vertically, we argue that this provides a helpful lens for making sense of the drivers of penal policy, especially the historical particularities of any penal phenomenon.
