This framework is designed to help senior decision-makers develop and implement new problem-solving courts (of which the Ministry of Justice’s initiative to pilot Intensive Supervision Courts (ISCs) is the latest Government funded programme) in the adult criminal court system. It gives a clear understanding of what constitutes a problem-solving court, a summary of the evidence base supporting these approaches, and lays out practical steps and checklists for building the partnerships, processes, and governance needed to launch, implement and sustain a problem-solving court.
