This bit is interesting (about what defamation is):
where no defence (usually truth, opinion, or qualified privilege) is available
So even if it was said outside of parliamentary privilege, Winston could just say it’s his opinion. But the media could get in trouble for reporting he said it because it’s not their opinion!
I’m sure it’s structured this way for a reason, after all, rules are written in blood, but to an outsider it seems like it would prevent a lot of political news being published!
Now how come they can print that Julie Anne Genter yelled at a florist? They only have the florist’s word. Its that enough to prove truth? We only have Winston’s word about the other guy.
