Of course it is Eleanor, Dave is spot on this time. Defamation (libel or slander) have to be proven first and then the damages and compensation will follow. It ain't rocket science even in Portugal. 
It's odd though, isn't it, that no accusations ( or even mention ) of what, specifically, was libelous in Amaral's book were made in court
The McCanns' lawyer made no attempt to show that what Amaral had written was not true ( or libelous ) ... she merely made the case for how much damage the book had caused to her clients and the search for their missing daughter
Similarly, all the McCanns' witnesses testified as to the level of damage the book had caused them, and nothing else
As far as I could tell it was not established that the book had 'libelled' the McCanns at all ... I did not see where that was even attempted
The trial, so far, has seemed, to me, to be all about the amount of damage it caused the McCanns
Did others see it differently ?
