To add a little colour here, Mr Defteros was previously awarded damages and costs when he sued the authors of the article (and book chapter). Google was notified of the defamatory material in February 2016, but did not remove it until December 2016 after it had been accessed ~150 times.

In this case the court found -- paraphrasing a lengthy judgement here -- that having being notified of the defamatory material, and failing to remove it, Google is a publisher of defamatory imputations. As such damages were awarded.
