André, you are right: I know nothing about Law. I´m just a regular citizen that knows that:
1. Brazil signed Hague Convention. Freely, it could have not signed.
2. I don’t know if Brazil added a footnote below the signature stating: “You know, guys, our courts are a bit slow, then although I´m affirming that children will be returned in 6 weeks, this is only a gag. In truth it will not be possible before 5 or 10 years.”
3. Brazil could freely have denounced the convention at anytime and get disobliged from its clauses.
4. Brazil benefited for the Convention, returning several kids in the last years.
Then, why should a president keep quiet if Courts need 4 or 5 years to decide about a case when an international convention signed freely by Brazil enforces a decision in 6 weeks?
I understand what separation of powers is about. I only don´t understand why the judiciary should be treated as the almighty god and executive, legislative and citizens, mainly, should only bow to its decisions or lack of decisions.
