This is actually discussed in the decision:

“The respondent did not sue The Age for defamation; instead, in 2010, the respondent sued two authors of a book that, amongst other things, contained a chapter based on the Underworld article. One of the two authors was also the author of the Underworld article. The claim settled at mediation, and it was a term of the settlement that the authors would make certain revisions to the book. In exchange, the respondent released the authors from all liability in relation to a number of matters, including any article published in The Age or its affiliated publications concerning the respondent.” [¶182]
