CAT/C/HUN/CO/4 page 5 Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment) become an integral part of the training provided to physicians. Furthermore, the State party should develop and implement a methodology to assess the effectiveness and impact of such training/educational programmes on the reduction of cases of torture, violence and ill-treatment. Data collection 12. The Committee regrets the fact that for certain areas covered by the Convention, the State party was unable to supply statistics, or appropriately disaggregate those supplied (e.g. by age, gender and/or ethnic group). During the current dialogue, this occurred with respect to, for example, the ethnicity of inmates and detainees, particularly the Roma (art. 11) The State party should take such measures as may be necessary to ensure that its competent authorities, as well as the Committee, are fully apprised of these details when assessing the State party’s compliance with its obligations under the Convention. Conditions of detention 13. The Committee is concerned that, notwithstanding the measures taken by the State party to improve conditions of detention, there is continuing overcrowding in prisons. The Committee is also concerned at allegations of some cases of ill-treatment by custodial/prison staff, including beatings and verbal abuse (arts. 11 and 16) The State party should continue its efforts to alleviate the overcrowding of penitentiary institutions, including through the wider application and use of alternative sentencing introduced by the new Act on Criminal Proceedings and the establishment of additional prison facilities as needed. The prison management should deliver a clear message to custodial/prison staff that ill-treatment is not acceptable. Ill-treatment and excessive use of force 14. The Committee notes with concern some allegations of excessive use of force and illtreatment by law enforcement officials, especially in the course of or in relation to apprehension. In this respect, the Committee is particularly concerned at reports emerging of alleged excessive use of force and ill-treatment by the police during the demonstrations in Budapest in September and October 2006 (arts. 12 and 16) The State party should give higher priority to efforts to promote a culture of human rights by ensuring that a policy of zero tolerance is developed and implemented at all levels of the police-force hierarchy as well as for all staff in penitentiary establishments. Such a policy should identify and address the problems, and should include the new Code of Conduct for Police Interrogations and introduce a code of conduct for all officials as well as regular monitoring by an independent oversight body. The State party should take measures to ensure that law enforcement officials only use force when strictly necessary and to the extent required for the performance of their duty.
