One of those stories was run in the mid 90s. The ABC famously went to court in Lange v Australian Broadcasting Corporation in 1997 and they were forced to change their methods over that case.
The other one was over this implied bullsh*t which I HATE in our tort system. We should have free speech with much more protection for the press. Like the American system.
The jury also dismissed most of his complaints. I really don't see what grounds Matthew Johns has to go on. Like could he argue that 4c implied he was a rapist. They quite explicitly said he wasn't.
They reported her feelings truthfully (regardless if what she said was true). I struggle to see where he has a case against Four Corners. If anyone can point out where he was defamed by four corners I would be very interested.
Four Corners are allowed to publish things that make people look sh*tty. So long as they can prove they are true and so long as they can prove that its in the publics interest. They also have a fairly light burden of proof.
EDIT
If anyone defamed him its the girl. Still that would be a tricky one to prove as well.
