Here is the nub of Portuguese Law on Personal Integrity:
"Under the aegis of ordinary law, the artº 70 of the Civil Code establishes the general protection of personality, stating that " law protects individuals against any illegal offense or offense of threat to their physical or moral integrity. "
On the other hand, even that civil law generally provides the artº 483º that "anyone who, intentionally or recklessly, unlawfully violates the right to another person or any legal provision intended to protect foreign interests is obliged to compensate the injured party for damages resulting from the violation "and the artº 484º specifically establishes that" anyone who claims or spread a fact capable of harming the credit or good name of any individual or legal, is liable for the damage. "
Pires de Lima e Antunes Varela state that it "exists or not, by the natural or legal persons, an individual right to credit and good name, it is considered as expressly wrongful conduct that threatens to injure them within the prescribed terms. Never mind that the fact stated or disclosed correspond to the truth or not, as long as is likely, given the circumstances, to reduce confidence in the ability and willingness of the person to fulfill their obligations (loss of credit) or shake the prestige of the person or enjoy the good concept that is taken (loss the good name) in the social environment in which he lives or carries on business."
Note that even if the statement is true, it still can be seen as damaging the person.
This is also the case in England where for instance if one paraded outside a private home 12 hours a day with a placard detailing the criminal acts of an individual, one would be both civilly and criminally liable for harassment- because although the matter of fact was true, it was being used in an illegal manner.
If one were in that position one could call on the police to remove the person for Breach of the Peace, or if repeated ask for the person to be arrested for harassment. Or one could take out an injunction to estop the person from parading outside ones house, or sue the person for personal injury in the civil courts.
The important fact to grasp is that the same facts repeated by the TV and CD producers and the book publishers was not an offence of libel becasue their Free Speech was protected under the law, but Amaral lost the right to Free Speech on the issue because he misused his privileged position to harass and cause damage to the Mccanns.
Davel- the quote you give is from the section where the jusge is deciding the 'Quantum', amount of the damages and using case law in similar cases that showed that damages could be set to compensate for the monetary advantage that an offence such as libel might have resulted for the respondent. The judge seems to have balanced Amaral's profits from the book against the award to the McCanns.
