14 CPT: 14TH GENERAL REPORT COMBATING IMPUNITY 25. The raison d’être of the CPT is the “prevention” of torture and inhuman or degrading treatment or punishment; it has its eyes on the future rather than the past. However, assessing the effectiveness of action taken when ill-treatment has occurred constitutes an integral part of the Committee’s preventive mandate, given the implications that such action has for future conduct. The credibility of the prohibition of torture and other forms of ill-treatment is undermined each time officials responsible for such offences are not held to account for their actions. If the emergence of information indicative of ill-treatment is not followed by a prompt and effective response, those minded to ill-treat persons deprived of their liberty will quickly come to believe – and with very good reason – that they can do so with impunity. All efforts to promote human rights principles through strict recruitment policies and professional training will be sabotaged. In failing to take effective action, the persons concerned – colleagues, senior managers, investigating authorities – will ultimately contribute to the corrosion of the values which constitute the very foundations of a democratic society. Conversely, when officials who order, authorise, condone or perpetrate torture and illtreatment are brought to justice for their acts or omissions, an unequivocal message is delivered that such conduct will not be tolerated. Apart from its considerable deterrent value, this message will reassure the general public that no one is above the law, not even those responsible for upholding it. The knowledge that those responsible for ill-treatment have been brought to justice will also have a beneficial effect for the victims. 26. Combating impunity must start at home, that is within the agency (police or prison service, military authority, etc.) concerned. Too often the esprit de corps leads to a willingness to stick together and help each other when allegations of ill-treatment are made, to even cover up the illegal acts of colleagues. Positive action is required, through training and by example, to promote a culture where it is regarded as unprofessional – and unsafe from a career path standpoint – to work and associate with colleagues who have resort to ill-treatment, where it is considered as correct and professionally rewarding to belong to a team which abstains from such acts. An atmosphere must be created in which the right thing to do is to report ill-treatment by colleagues; there must be a clear understanding that culpability for ill-treatment extends beyond the actual perpetrators to anyone who knows, or should know, that ill-treatment is occurring and fails to act to prevent or report it. This implies the existence of a clear reporting line as well as the adoption of whistle-blower protective measures. 27. In many States visited by the CPT, torture and acts such as ill-treatment in the performance of a duty, coercion to obtain a statement, abuse of authority, etc. constitute specific criminal offences which are prosecuted ex officio. The CPT welcomes the existence of legal provisions of this kind. Nevertheless, the CPT has found that, in certain countries, prosecutorial authorities have considerable discretion with regard to the opening of a preliminary investigation when information related to possible ill-treatment of persons deprived of their liberty comes to light. In the Committee’s view, even in the absence of a formal complaint, such authorities should be under a legal obligation to undertake an investigation whenever they receive credible information, from any source, that ill-treatment of persons deprived of their liberty may have occurred. In this connection, the legal framework for accountability will be strengthened if public officials (police officers, prison directors, etc.) are formally required to notify the relevant authorities immediately whenever they become aware of any information indicative of illtreatment.
