This is not about defamation - that was ruled out in the previous Court case -, this is about damages and losses.
Well, you're half right and half wrong.
The ex-parte judgment did not consider libel.
That's because the present proceedings are all about libel.
If the present court case was about libel, there would be a discussion about the contents of the documents, which has occurred before. If you read carefully the depositions of the witnesses and the questions that are put to them, there is no question whatsoever about the contents of the documents, but about its consequences.
Compensations in libel cases imply that the defamatory object, document, declaration, ...is proven to constitute a crime of defamation. That chance was lost when the Appellate court ruled them as legal and not defamatory.
What Isabel Duarte is invoking here is a Civil Law - Civil Responsibility - that obligates persons or organizations to compensate others for damages suffered even when there was no intent.
