It might help to examine the first judgement. The judge said that Amaral said nothing that hadn't been said before.
Now the thesis that the minor died accidentally in the apartment and that this fact was hidden by her parents, who spread and fed, in order to deceive, an hypothesis of abduction, is not new, there's nothing new neither in the book, in the interview or in the documentary.
One wonders then what is the difference between 1) asserting – as it was done at a certain step of the investigation or as many commentators do – that there are indices of accidental death, concealment of the corpse and simulation of crime and 2) supporting this view as did the defendant Goncalo Amaral in those three mediums.
So far, freedom of speech wins. But there are limits on it;
The presumption of innocence prohibits, according to these decisions, the premature expression of opinions or beliefs of guilt by the courts but also assumptions by public officers involved in procedures which might lead the public to suspect the responsibility of the suspects in the facts under investigation.
Having been in charge of that investigation as a member of the Judicial Police, the defendant Goncalo Amaral, although retired on 1st July 2008, did not enjoy, on the following July 24, in respect of the results of the criminal investigation released on the 21st of the same month and year, a large and full freedom of expression. This freedom was conditioned by the functions he had, functions that imposed him special duties that traverse the status of retirement, including the duty of reserve.
So the judge is saying that Amaral damaged the McCanns not by what he said in the book, the interview and the documentary, but by failing to observe the limitations imposed upon his freedom to speak by his former profession, by which he was still bound in retirement.
Is it, therefore, correct to say he libeled the McCanns in his book? No judge has ever actually said that he did, as far as I can understand it.
