47 his testimony that he agreed to his case being publicly known as a way to contribute in avoiding events as the ones he suffered from happening to others. Along these lines, the Court considers that the State must include Mr. Wilson Gutiérrez-Soler’s case in the program mentioned in paragraph 106, as a teaching aid to contribute towards preventing this sort of events from happening again. 108. On the other hand, although studying the Inter-American System for Human Rights Protection precedents is a crucial factor to prevent ocurrences such as the ones that befell Mr. Wilson Gutiérrez-Soler, the State must also adopt the necessary measures so that such precedents, as well as those of the Constitutional Court of Colombia regarding military jurisdiction, be effectively followed in domestic courts. e) Implementation of the standards in the Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (“the Istanbul Protocol”) 109. The Court notices that the expert witness María Cristina Nunes de Mendonça (supra para. 42), pointed out that the examinations practised on Mr. Wilson Gutiérrez-Soler are incomplete, for they lacked photographic records, and also because examinations for internal injuries were not conducted. According to the expert witness, such omissions influenced the subsequent construction of the examinations and the outcome of the domestic proceedings, which were instituted as the result of the events in the instant case. She also pointed out the importance of implementing the standards of the Istanbul Protocol in cases of torture, for it describes how to conduct a medical examination and how to draft reports about victims of torture or cruel, inhuman or degrading treatment. By reason of the foregoing, the expert witness specified that observing said standards prevents such facts from going unnoticed and remaining unpunished. 110. Along such lines, the Court deems that by disseminating and implementing the standards of the Istanbul Protocol may contribute effectively to protecting the right to humane treatment in Colombia. For such reason, the State must implement a training program including said international standards, to be taken by physicians working in official arrest centers and by National Institute of Legal Medicine and Forensic Sciences staff, as well as by prosecutors and judges in charge of investigating and trying cases such as the one affecting Mr. Wilson Gutiérrez-Soler, so as to provide such staff with the necessary technical and scientific know-how to assess possible cases of torture or cruel, inhumane or degrading treatment. Likewise, the Court considers it necessary that such training program include the Wilson Gutiérrez–Soler case as a measure aimed at preventing repetition of such kind of events. f) Strengthening controls of arrest centers 111. The Commission and the State agreed on the need, as a preventive measure, to strengthen existing controls with respect to persons arrested in Colombia. The Commission likewise indicated that the constant psychological evaluation of state staff who are in contact with persons arrested would constitute an important preventive measure; moreover, it declared that a physical examination of persons arrested upon arrival at the arrest center could contribute to detecting acts of torture, or cruel, inhumane or degrading treatment.
