CAT/OP/BOL/3/Add.1 204. In this context, with a view to meeting current social challenges, it was decided to transition from an individual to a team-based approach, changing paradigms and prosecutorial processes. The prosecution management model currently being implemented includes the following elements: 205. Platform. To provide support and guidance to users who visit the Prosecutor’s Office to request prosecutorial action in a particular conflict and refer them to the appropriate body; if the conflict in question is not criminal in nature or if it involves victims in crisis, it can be dealt with promptly by the Victim and Witness Support and Protection Unit, in accordance with the applicable protocols. 206. Effective filter. Made up of analysis units with a filter system that can distinguish cases that are obviously criminal from those that are not, thus avoiding the processing of non-criminal cases (family, labour, civil cases), which, based on the principle of ultima ratio, should not enter the criminal system. This prevents the criminal system from being used as a means of extortion, pressure or bribery thanks to the effective dismissal of cases, with the effect that more than 15,644 cases have been dismissed so far in 2017. 207. Prosecution teams. Implemented based on the principle of unity of the Public Prosecution Service and organized according to needs, they make it possible to increase efficiency and capacity for dealing with cases and promote criminal investigation and prosecution, avoiding arbitrariness and judicial delays. Up to the third quarter of 2017, a total of 119,815 cases from previous years and the current year were closed at the national level. 208. Alleviating the prosecutorial caseload. By applying legal principles such as the criteria of regulated opportunity, conditional stay of proceedings, conciliation and summary proceedings, in other words alternative sentences, fostering social peace, rejecting and dismissing cases when there is insufficient basis for prosecution and avoiding judicial delays that lead to corruption, impunity and a lack of public trust. The introduction of prosecution teams has improved the exercise of criminal action, resulting in the resolution of more cases in less time, as shown in the following table. 2017 Active caseload as at 1 January 2017 Cases closed in 2017 carried over from previous years Percentage reduction of caseload Chuquisaca 9 768 4 809 49.23 Pando 2 350 935 39.79 Beni 5 467 2 035 37.22 Tarija 12 763 4 683 36.69 La Paz 117 724 40 638 34.52 Oruro 11 084 3 671 33.12 Potosí 5 440 1 743 32.04 Cochabamba 18 229 4 582 25.14 Santa Cruz 86 295 19 343 22.41 269 120 82 439 30.63 Overall total 32 GE.18-12244
