For me, aside from the second-hand evidence which he hadn't refuted. The evidence was in his first public statement after Kim announced she was going to do a livestream with me. Where he said anyone he had seen "sex worker or otherwise". He needs to show hard evidence the sex worker he "dated" was in fact really dating. The defense has to prove it had reason to believe that these allegations were true. Part of that defense is that Lloyd has a history of lying. Then, get him on the stand and show him lying again. Without any verifiable evidence, evidence that has never been given to the defense, my understanding of the Croatian laws around this is that he would lose his case. Defamation and libel require malice. Something he won't be able to prove.
All of his "evidence" is going to be his word against ours or evidence no one saw. So they had a reasonable reason to believe what they saw was true. That's why it's so difficult no matter what country you're in to win a case. Especially in a country like the USA where there is a jury. He would have 0% of winning any case he filed there. Solely because he'd be so unlikable to a jury and a proven liar.
This of course is ignoring the basic legal principle of jurisdiction. He has to prove the crime took place on Croatian soil. Or have some sort of extradition treaty for low-level crimes.
My theory now is he is betting on the Croatian court system being "glacially slow" knowing full well they will reject it. All the while he can let this blow over and recover. Just a tough time in the distant past. When the court made a decision he and his lawyers were caught off guard. Now they can re-file and cross their finger. Hoping it takes longer this time.
It will likely backfire again and the biggest loser will always be his pocketbook. The thing some might speculate he is likely trying to make look as small as possible for his ex-wife. Alimony and child support are coming if she is indeed following through with the divorce.
