This article offers a multilayered analysis of the subjective perspectives and experiences of key youth justice stakeholders; exploring the inherent dynamism, contradiction, non‐linearity, and contentiousness of youth justice policy implementation. We interrogate how professionals make sense and meaning of policy in the real world and how professional perspectives drive and shape their contributions to policy implementation nationally and locally. Contemporaneously, these analyses enable us to critically examine the caricatures, stereotypes, and assumptions that can (mis)inform common constructions, representations, and understandings of youth justice policy trajectories, including those relating to contextual stability, conceptual clarity, robust evidence bases, and purported foundations in stakeholder consensus.
