 Parental alienation is a phenomenon in which the abducted child displays an antipathy towards the other parent and in which this antipathy is actively encouraged by the abducting parent.In June 2010 it was reported that a constitutional amendment incorporating parental alienation syndrome into the Brazilian legal code would have a bearing on child custody cases.In 2001, a federal judge in Santos issued the first ever judgement in Brazil under the Hague Convention, calling for the return of a child to his habitual residence in Sweden.
