Discussing what was said in the book is of no use as the judge didn't address that issue or rule on it. The issue, for her, was whether Amaral was entitled to express his opinion. She decided he was not, and awarded damages accordingly.
A first conclusion is that if the book is about an hypothetical checking of the facts or about the opinion of the author on how the evidence collected in the investigation should be read, one shouldn't speak of falsehood, untrue facts, and it doesn't make sense, without a better understanding, to discuss the "exceptio veritatis"
The means of obtaining evidence and the evidence referred to in the book are those of the criminal investigation and most of the facts that the book is concerned with (as well as those referred to in the documentary and interview), when related to the criminal investigation, are mostly facts that occurred or are documented in the investigation (n° 80 of the proved facts).
In our view, the issue, in this trial, is the exercise of the right of opinion by the defendant in that context.
