An attempt by the blogger Cameron Slater to use a journalist's legal protection for sources has failed.
The case came after the High Court told the Whaleoil blogger he qualified as a "journalist" but couldn't hide sources for a series of blog posts about a businessman using a journalist's legal protection because of the nature of the posts.
The case involves defamation proceedings taken by business Matthew Blomfield over blog posts made by Slater in 2012. High Court Justice Raynor Asher had ruled there was a "public interest" in the sources being identified as there was no public interest in coverage of Blomfield's affairs and because of the "extreme and vindictive" nature of the disclosures. He also found the claim for journalistic source protection weakened because "the documents disclosed by the sources appeared to have been obtained illegitimately".
The Court of Appeal has now rejected arguments by Slater that new evidence should overturn Justice Asher's ruling and allow him to engage source protection rules for journalists in the Evidence Act.
Slater argued he had new evidence showing his informants were at risk from Blomfield, also arguing the hard drive from which he had drawn source material was not gained illegally.
