Annual Report 2014 of the National Preventive Mechanism ordered, their regular supervision and the material conditions in which they are implemented, in addition to the policies for the use of physical and pharmacological means of restraint 59. Any regulation having effects on the manner of carrying out a deprivation of liberty necessarily implies a direct effect on fundamental rights. For that reason, it should be demanded that such regulations, which are essential to establish the manner in which to proceed in such cases, have a high ranking of law, avoiding their regulation through instructions or circulars. Such instruments do not meet all the requirements established for legal provisions, since they do not address citizens in general but only the personnel involved, and the process for their preparation does not respect the procedure and safeguards pertaining to the adoption of laws. 60. In view of the heterogeneous structure and size of the local police forces and the need to ensure an impartial procedure for evaluation of the actions of the members of the smaller police forces or the persons to which they report directly from a political point of view, it would be advisable to establish unified inspection systems for the set of personnel of these forces so that they are homologated in this respect with the large national or autonomous community security forces. The Inspectorate of Security Personnel and Services of the SES could be used as reference, as a theoretical model with regard to operating issues. 61. If the responsibility for a person deprived of liberty must be transferred to a different facility or corps, it should be required, in addition to the customary procedures of action, that it be verified that the transferred person does not show signs of having suffered ill-treatment either physical or mental, carrying out, in the case of doubt, even if the person in question does not request this expressly, an immediate medical examination permitting any irregularity to be detected. 62. In line with the suggestions of the SPT, it would be advisable for information (notices, informative brochures, etc.) on the prohibition from torture and illtreatment, and on the manner in which and the person before whom to bring complaints against these acts, visible to the public and easy to understand, to be available at all facilities at which persons deprived of liberty are held. 63. Prevention is an essential factor in the battle against torture and ill-treatment. In this respect, video-surveillance and video-recording play a relevant role in the prevention of improper conduct by personnel providing services at places of deprivation of liberty. In addition, in the case of complaints, they provide unequivocal evidence to verify the accuracy of the claims. Although, as mentioned above, the installation of these devices and the various facilities has increased, great disparity continues to be observed as regards their use. These technical devices should be used at all facilities where persons deprived of liberty may remain, although excluding certain areas such as rooms for confidential interviews with lawyers or religious ministers, or for intimate of family meetings, toilets and cells or rooms in mean- or long-term deprivation of liberty. 40
