The best interests of the minor at present constitute a guiding principle that governs parent-child relationships and regulates the scope of parental responsibility. Its projection has also irradiated the penal sphere, an area in which a series of measures are applied to avoid the re-victimization of the infant. From this perspective, mediation is an ideal way to assertively handle conflict with the intervention of minors. However, the judicial body?s performance is still a question mark, when parents without a well-founded reason deprive the infant, victim of a crime, of participating in a mediation process, carrying a risk of re-victimization due to the emotional exhaustion generated by the criminal process. The article analyzes the best interests of the minor from a transversal approach, accentuated in the penal field, and the limitations that this postulate imposes on the exercise of parental authority. Likewise, the aspects of mediation that qualify it as an effective instrument to guarantee human rights are evaluated, especially those related to the well-being of infants.
