The court didn't accept the claim that he was Satoshi afaik. Cobra didn't defend himself so CSW won the court case by default since Cobra didn't want to reveal his identity from what I understood. Now what's confusing is did the court accept the side of CSW about his claim being Satoshi and writing the white paper, or did the court just, well, defaulted and didn't really bother identifying whether his sides' claims were true or not. Though it seems to be saying that CSW owns the paper just based on the decision they made since I don't think a punishment would've been handed out if the court didn't agree with CSW (Correct me if I'm wrong, idk much about court cases)
The section of default ruling:
https://www.justice.gov.uk/courts/procedure-rules/civil/rules/part12As Cobra chose to not compromise his privacy (by filing an opposition or through a legal representative), the court reached the default ruling. This doesn't mean that CSW's claims were valid, it is just that they weren't (able to be) disputed in the court so there isn't any meaning to that. From what I understand, there was a written defense by Cobra (?) but it didn't matter.
