The Defence makes a good argument re: the wording of the espionage law. Did Ravania gather information *for* the UDL under the guise of a loyal TNP resident, or did he just share information that was already gathered. The evidence points to the latter, but the wording of the seems to suggest the former must be necessary to stand as espionage.
That being said, Prosecution Exhibit A shows him saying he'll organise it into a PDF, and then he posts the link. He used his position to gather information FOR the people in the UDL who wouldn't otherwise have access. They asked for screenshots, they asked for proof/more information, and Rav willingly obliged. Regardless of whether or not he was thinking, he still used his TNP nation to gather info for the UDL, and I think the Espionage laws cover that.
As for the treason charge... While I agree that providing classified information is and should be classed as providing material support, I'm not convinced by the evidence or arguments put forward that it was done *for the purpose of* undermining/overthrowing the lawful government. While Unibot did try and use the information to his advantage, it was after the fact, and I see no evidence that shows Rav did it SO Unibot would use the information.
I can see an argument that the reason for providing the logs was to show there was disharmony in the Government surrounding the decision and that people weren't happy with the Acting Delegate's decision and that this constitutes the Government being "undermined", but I think that's a very liberal definition of undermined and, in the context of the piece in the Legal Code, not the definition we should be applying.
So, my two cents are that I think espionage has been proved, but treason has not.
