CAT/C/NOR/CO/5 page 4 Education on the prohibition against torture 11. While noting that different training programmes for police and prison officers which cover human rights and rights of detainees, including the prohibition of torture, are systematically held, the Committee regrets that there is no available information on the impact of the training on reducing incidents of violence and ill-treatment, including incidents that may be racially motivated. The State party should ensure that through educational programmes, law enforcement personnel and justice officials are fully aware of the provisions of the Convention, applicable limitations on the use of force and the need to avoid any discriminatory treatment. Furthermore, the State party should develop and implement a methodology to assess the effectiveness and impact of relevant training programmes on the incidence of cases of torture, violence and ill-treatment. Prompt and impartial investigations 12. The Committee notes that the State party has taken measures to further improve the handling of complaints against the police and the investigation of relevant allegations. Nevertheless, the Committee remains concerned about allegations concerning violations committed by law enforcement officials, including allegations relating to discriminatory treatment, and about the impartiality of subsequent investigations. The State party should closely monitor the effectiveness of the new procedures for the investigation of alleged crimes committed by law enforcement officials, in particular those in which discriminatory treatment based on ethnicity is alleged. The State party is requested to provide detailed information on the results of the ongoing review process in its next periodic report. Provisional measures 13. In light of a recent case in which the State party’s initial response to a request by the Committee for provisional measures was unfavourable, the Committee is concerned about the State party’s general position with regard to requests for provisional measures by the Committee. The State party should consider its position with regard to interim measures requested by the Committee in light of article 22 of the Convention and the principle of good faith, with a view to generally allowing the Committee sufficient time to consider any case that may arise in the future before any action is taken. 14. The Committee notes the State party’s assurance that measures are being undertaken to seek the ratification of the Optional Protocol to the Convention, and encourages the State party to proceed to ratify the Protocol at the earliest possible date. 15. The Committee invites the State party to ratify the core United Nations human rights treaties to which it is not yet a party. 16. The Committee invites the State party to submit its core document in accordance with the requirements of the harmonized guidelines on reporting (HRI/MC/2006/3).
