The Committee urges the State party to take all necessary legal and administrative guarantees to ensure that this restriction will not be misused, that it is used only in the case of very serious crimes, and that it is always authorized by a judge. The State party should provide in its next periodic report additional information concerning the standardization of techniques used to interrogate persons in police custody and the implementation of new techniques, particularly the use video-recording of interrogations, which the Committee encourages the State party to continue but not as an alternative to the presence of counsel. Additionally, the Committee requests details on the measures taken to monitor and evaluate the use of the techniques referred to. (12) The Committee is particularly concerned about the inadequacy of the legal aid system. The Committee urges the State party to implement the recommendations of the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment to establish a fully fledged and properly funded system of legal aid. (13) The Committee is concerned at the reported physical presence of police officers during medical examinations of persons in police custody. The State party should take appropriate measures to ensure that police officers are not present during medical examinations of persons under police custody in order to guarantee the confidentiality of medical information, save under exceptional and justifiable circumstances (i.e. risk of physical aggression). (14) The Committee is concerned about the conditions of detention of juveniles, particularly that persons under 18 in places of detention are not always separated from adults. The State party should: (a) Develop alternative measures of detention for juveniles; (b) Ensure strict separation of juveniles and adults in places of detention; (c) Take preventive measures to avoid physical ill-treatment of juvenile detainees, including adequate training of officers dealing with juveniles; (d) Issue clear instructions from senior officers, both oral and written, that abusive conduct towards juveniles will not be tolerated. Prevention of acts of cruel, inhuman or degrading treatment (15) The Committee is concerned about the reported attitudes of racism and intolerance towards foreigners manifested by some law enforcement officials, such as cases of verbal abuse of Roma and people of African descent. The State party should continue to be vigilant in ensuring that the relevant existing legal and administrative measures are strictly observed and that training curricula and administrative directives constantly communicate to staff the message that verbal and physical ill-treatment will not be tolerated and will be sanctioned accordingly, and that racial motivations will aggravate the offences. The State party should provide the Committee with data on cases of torture and ill-treatment where the aggravating factors as stated in section 33 of the Austrian Criminal Code, including racism and xenophobia, have been invoked in the assessment of punishment of offences. 10
