CAT/OP/BOL/3 130. In accordance with the provisions of articles 2 (4), 12 (b) and (d) and 14 (1) (a) and (b) of the Optional Protocol and in fulfilment of its mandate, the Subcommittee will continue to actively engage in follow-up actions as part of its dialogue with the Plurinational State of Bolivia with a view to the protection of the rights of persons deprived of their liberty. 131. Having undertaken a rigorous analysis, the Subcommittee considers that the State party has not taken sufficient steps to ensure that all suspected reprisals and acts of intimidation are promptly, impartially and effectively investigated and that those responsible are brought to justice, in accordance with article 13 of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment and article 15 of the Optional Protocol thereto. Therefore, and taking into account that the State party has not implemented the Subcommittee’s other recommendations either, the Subcommittee proceeds to invoke the mechanism provided for by article 16 (4) of the Optional Protocol. VIII. Conclusion 132. It is the Subcommittee’s expectation that the State party will establish a solid institutional structure for the prevention of torture as a matter of priority. The Subcommittee urges the authorities to implement the recommendations set forth in each of its visit reports and to authorize their publication. 22 GE.18-12272
