CAT/C/LUX/CO/6-7 The State party should take the legislative and administrative measures necessary to expedite the opening and operation of the Dreiborn closed security unit for minors and ensure, in the interim, that juvenile detainees and prisoners under 18 are always held separately from adults, in line with the provisions of the United Nations Standard Minimum Rules for the Administration of Juvenile Justice (the Beijing Rules) (rules 13.4 and 26.3) and the United Nations Rules for the Protection of Juveniles Deprived of their Liberty (rules 17, 28 and 29). It should employ alternatives to incarceration, taking into account the provisions of the United Nations Standard Minimum Rules for Non-custodial Measures (the Tokyo Rules) and the United Nations Rules for the Treatment of Women Prisoners and Non-Custodial Measures for Women Offenders (the Bangkok Rules), and ensure that minors are always tried in juvenile courts. Training 14. While noting with appreciation the detailed information received by the State party regarding the training of civil service employees involved in the arrest, custody, detention and imprisonment of persons, the Committee regrets that there is no information available on the impact of training on preventing torture and ill-treatment. It is concerned that it did not receive sufficient information on the training of personnel on their specific obligations under the Convention and of medical practitioners involved in the treatment of detainees and asylum seekers (arts. 10 and 11). The State party should: (a) Ensure that officials involved in the arrest, custody, detention and imprisonment of persons are trained on and aware of the specific obligations imposed on them under the Convention; (b) Ensure that all relevant staff, including medical personnel, are trained specifically to identify cases of torture and ill-treatment, in accordance with the Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (the Istanbul Protocol); (c) Develop and implement a methodology for assessing the impact and effectiveness of training programmes with regard to preventing torture and illtreatment. Powers of the Public Prosecutor 15. As expressed in paragraph 11 of the Committee’s previous concluding observations (CAT/C/LUX/CO/5), the Committee is concerned about the Public Prosecutor’s discretion to decide whether to prosecute perpetrators of acts of torture and ill-treatment involving law enforcement officers or even order an investigation (arts. 12 and 13). The Committee reiterates its previous recommendation. The State party should ensure that whenever there are allegations of torture or ill-treatment they are investigated promptly and effectively and that perpetrators are sanctioned accordingly. Investigative powers of the Police Inspectorate 16. The Committee welcomes the appointment of a judicial magistrate as the head of the Police Inspectorate as a measure to improve the independence of the Inspectorate. However, it is concerned that the investigatory body, which is a part of the Ministry of Internal Security and composed of former police officers, is not sufficiently independent to ensure the proper and impartial investigations of complaints of police misconduct as required under the Convention (art. 12). 4
