those exercising supervisory tasks based on failure to comply with their control obligations; ii) The opening of administrative case files based on complaints made by the next of kin of inmates, newspaper articles, and complaints forwarded by the Human Rights Directorate of the Ministry of Governance; iii) The opening of a criminal investigation by the office of the Prosecutor for Complex Crimes of the province of Mendoza, whose current status is: (a) three individuals charged with the crime of torture; (ii) one person charged with the offense of harsh and humiliating treatment; (iii) one person charged with the crimes of torture in conjunction with the offense of harsh and humiliating treatment, and (iv) two individuals charged with the offense of omission in performance of functions which permitted torture. The six accused are currently detained in the Boulogne Sur Mer Complex (the agent accused of the offense of harsh and humiliating treatment has been released). The Minister of Governance, Justice and Human Rights, the Deputy Secretary for Human Rights, the Director of Human Rights and the Director General of the Prison Service, all of the province of Mendoza, and also the federal State – through the national Human Rights Secretariat – are the complainants in the case; iv) The creation of delegations of the Provincial Human Rights Directorate in each prison to receive statements and complaints of different kinds. 39. The irreparable nature of possible harm to the rights of those deprived of liberty is evident if pertinent measures of prevention and protection are not adopted at the domestic level. In view of the special severity of the situation denounced, the obligation to ensure the protection of those directly involved in the facts must be stressed, as well as of other inmates who could be victims or witnesses should similar acts occur, and also not to thwart their due investigation owing to the presence of other prison staff and the possible obstacles this could represent, including to prevent threats, intimidation or reprisals. 40. Irrespective of whether the requirements concur to order the protection of those deprived of liberty in these prisons, the Court has reiterated that, based on the principle of complementarity and subordination that governs the inter-American human rights system, an order to adopt or maintain provisional measures is only justified in situations established in Article 63(2) of the American Convention, in which the ordinary guarantees that exist in the State regarding which they are requested are insufficient or ineffective, or the domestic authorities cannot or do not want to ensure their effectiveness.20 The State has provided information on numerous, significant measures that its administrative and judicial authorities are adopting as a result of the reported facts (supra twenty-first and twenty-second considering paragraphs), which would indicate the willingness of the authorities to set in motion specific mechanisms of prevention and investigation at the domestic level. In other words, the domestic authorities have responded to the situation in the Mendoza Prisons since the Court 20 Cf.
