It is well worth a read to see why the McCanns will probably be successful in the ECHR. Bear in mind that in the case the Portuguese SC used to arrive at their judgement (Fernandes e Fernandes) the person libelled was at the top of the Portuguese justice system & his working life was very much under public scrutiny - he was accountable to the public through the justice system. His right to privacy was less than the McCanns under Article 8.
IMO.
The case you have linked to appears to concern a newspaper strongly suggesting that one of the people interviewed by the police was the 'prime suspect'. They also made it possible for others to identify him.
The man wasn't a suspect, he was a witness. As a result of the newspaper article he lost his home and job and suffered hardship.
The ECHR ruled that the newspaper violated his right to respect for his private life under
Article 8.
The McCanns were suspects, not witnesses, as documented in the official files.
He described why they became suspects, using the official files as his basis.
They weren't exposed to the public by anything Amaral said, they were already firmly in the public eye.
They were unable to prove any damage to their private lives by Amaral.
