I have looked through the 2007 Penal Code.
Which statutes back in 2007 do you find incompatible with private attempts to find your missing child?
The Penal Code won't be that specific but Antonio Martins, president of the National Association of Portuguese Judges, told the newspaper 24 Horas: "It is still up to the state to carry out criminal investigation. That kind of private activity has no legal standing".
"Anything that results from private investigation has no substance."
Mr Martins said the private detectives and even the McCanns themselves could be accused of "obstruction of justice".
Carlos Anjos, the head of Portugal's criminal police federation, added: "This can only be another diversion tactic from the McCanns. It is nothing but folklore.
"Portugal does not have legislation in this area. Private detectives who intervene in criminal cases cannot exist.
"The law only tolerates private detectives who gather information and only about matters of the private lives of certain people like extramarital relationships."
A separate police source warned that the involvement of investigators may not only be illegal but could have a detrimental effect on the inquiry.
The high ranking official told newspaper Correio da Manha: "If private investigators come here they will be running a serious risk of being arrested."
They were arrested in any event, Halligen from Oakley and Marco from Metodo 3. Both companies are now defunct, bankrupt, bust. Karma works in mysterious ways imo.
