 These decisions contradict the Convention, because the concept in the Brazilian legal system of "best Interests of the Child" is broader than the narrow concept described in the Convention, as the Preamble of the Convention declares that the interest of children is attained through their return to their country of habitual residence.In addition, the USCA notes that judges in some cases continued to demonstrate a bias towards mothers and towards Brazilian citizens.Further, the judicial process is excessively lengthy, with cases going on well beyond the six weeks mandated by the Convention."
