What was the evidence cited in the court ruling against Johnny Depp in the libel case?

So as we know, 12 of the 14 cases of domestic abuse were apparently found to be true by the British court that ruled in favour of The Sun. I read The Guardian’s article on the case, and seen people online talk about it but I have yet to find the concrete evidence that’s behind the decision, besides a message from Depp talking about how he hates Amber. But surely, that cannot be the only thing. Right?
