The purpose of this article is to analyze the case Fornerón and daughter vs Argentina, decided by the Inter-American Court of Human Rights in April 2012. The case focuses on three main topics: (i) the superior interest of the child, due process and judicial protection in cases related to family law; (ii) the international standards on human rights to protect the biological link between parent and child; and (iii) the duty to implement internal regulations to protect the child and the family in adoption procedures. The article will focus on two areas of analysis. First, it will assess the standards set by the Inter-American Human Rights System on the protection of the child, specifically in adoption processes and the protection of the biological link between parent and daughter. The second part will analyze the obligations of the state to prevent the sale of children, proposing some guidelines that the Inter-American Court of Human Rights could have taken in this topic. Finally, the article will conclude with some information regarding the implementation of this decision and what this case might mean for state parties to the American Convention on Human Rights.
