I remember reading an article on the patterns of a justice system that operates as a sort of theater, where citizens can observe justice being done by the state. Apparently (at least in places) there's a special focus on the guilty plea; a plea of innocence is tantamount to revolt, a declaration that the agents of the state have wronged you. Pleading guilty, on the other hand, shows a strong and useful picture of an evildoer throwing her/himself on the mercy of the wise and powerful state and submitting to its judgment.
The system's facial goal is the same as we have in the United States. The practical aim, however, differs greatly.
This is a game I can see the Caldari playing-- justice as propaganda, essentially. It's less important whether the accused is truly innocent or truly guilty, and more important that the accused submits to the judgment of the authorities.
Note that this system only works if its true nature is little-understood outside of those who participate in it. Transparency is toxic to it, but neither corporations nor dictatorial power structures in general are known for their transparency.
