The audit focused on the administration's actions to streamline protracted criminal procedures. A criminal procedure is a chain consisting of a preliminary investigation, consideration of charges and court proceedings. The audit focused on the years 2010–2024. The audit assessed how the administration has investigated the causes of the prolongation of criminal procedures and how efforts have been made to streamline the processes. The central focus was on the authorities' ability to manage the process as a whole. The ministries responsible are the Ministry of Justice and the Ministry of the Interior. Reports to streamline the processes had been carried out regularly throughout the period covered by the audit. The reports contained many proposals for measures to streamline the process, and they targeted all authorities involved in the process. The administration had made few proactive or ex post assessments of the effects of the measures. Information on the effects of the measures would be useful when planning and selecting future measures. The administration has made several legislative changes to streamline the process of handling criminal cases. At times, the implementation of the proposals has been slow. The targets for speeding up the processes have been set for each authority. There are no common targets for all actors. The National Audit Office recommends that the responsible ministries assess the impact of the measures on the duration of the criminal process more carefully than at present, accelerate the implementation of the reforms, set common targets and create a cooperation structure to support the achievement of the targets.
