99. The guarantees enshrined in Articles 8 and 25 of the Convention are recognized for all people equally, and must correlate with the specific rights it establishes and with Article 19, in such a way that they are reflected in any administrative or judicial processes in which children's rights are discussed.174 In this regard, in compliance with Article 19 of the American Convention, States must adopt specific, special measures in cases where the victim is a child or adolescent, especially in the event of an act of sexual violence and, more so, in cases of rape, without prejudice to the standards established in cases of violence and rape against adult women.175 Consequently, in the framework of this case, the Court will analyze the alleged violations of rights to the detriment of a girl, not only based on international instruments related to violence against women, but will also examine them in light of the international corpus juris for the protection of children,176 which must serve to define the content and scope of the obligations assumed by the State when analyzing the rights of persons under 18 years of age,177 and in this particular case, of the enhanced state obligation of due diligence. 100. Thus, it should be emphasized that the special protection measures that the State must adopt are based on the fact that children and adolescents are considered more vulnerable to human rights violations, which will also be determined by different factors such as, inter alia, age, the particular conditions of each individual, their degree of development and maturity.178 As stated by expert witness Cillero, age is a potential factor of discrimination because “girls and adolescents, due to their age, do not have the social or legal legitimacy to make important decisions in matters of education, health and in relation to their sexual and reproductive rights.”179 Furthermore, as has already been pointed out by the Court, in the case of girls, said vulnerability to human rights violations can be framed and enhanced by factors of historical discrimination that have contributed to women and girls suffering higher rates of sexual violence, especially in the family environment.180 101. As the Court has pointed out, the duty to guarantee takes on special intensity when girls are victims of a crime of sexual violence and participate in investigations and criminal proceedings,181 as in this case. 174 Cf. Advisory Opinion OC-17/02, supra, para. 95. 175 Cf. Case of V.R.P., V.P.C. et al. v. Nicaragua, supra, para. 156. This Court has established in reiterated case law that both the American Convention and the Convention on the Rights of the Child, as well as other international instruments of varied content and legal effects that serve as a guide to interpretation, are part of a very comprehensive international corpus juris of protection of children and adolescents. This must serve to establish the content and scope of the general provision defined in Article 19 of the American Convention, read in conjunction with other rights contained therein, when the holder of rights is a person under 18 years of age.

Nicaragua, supra, para. 156. The Convention of Belém do Pará itself considered it pertinent to highlight that state policies aimed at preventing, punishing and eradicating violence against women had to take into account a girl or adolescent’s vulnerability to violence. Said Convention establishes in its Article 9 that the States Parties will take special account of the vulnerability of women to violence due to being a person under 18 years of age, so that in cases in which a girl or adolescent is a victim of violence against women, in particular sexual violence or rape, state authorities must take particular care in the development of investigations and processes at the domestic level, as well as when adopting protection and support measures during and after the process, in order to achieve the victim’s rehabilitation and reintegration.
