Pr0ner for defamation or libel to be proved you have to prove the person you're suing knowingly told a lie with intent to harm. As in, saw overwhelming evidence that what they were saying was untrue and still said it. His whole defense is "my word against theirs". The problem is that he will have to prove to a judge his word is good enough
I checked and the insult clause in Croatia (as well as a few other places) is considered by the ECtHR as an antiquated law originally aimed at protection of the office of a public, or government figure.
So...the office of the Head Dickhead EXJW??😂
You are correct it has a very high bar in respect of proof. It is not the Civil 'on balance of probabilities' but the criminal 'beyond reasonable doubt'.
So as you say, Lloyd will have to prove that each one of you made statements of fact (not opinions) intended to cause harm - knowing it was untrue.
