I wonder if a situation like that would play into tensions that might be present in the Caldari/Amarr relationship.
I mean, there are likely some corporations that aren't entirely happy with the stronger links. Not because of slavery or any of that, necessarily, but because they don't like the debts to the Empire or for other political reasons we don't know about.
There is also, to my mind, the strong possibility the State legal system is immensely complex, particularly for outsiders.
You're an Ammatar regional authority of some kind. You find out there's an Ammatar 'traitor' hiding in the State. The traitor was bright enough to do his research and find a corporation that isn't a big fan of the deals with the Empire.
So, Ammatar authority contacts the corporation in question to arrange extradition. Corporation says 'For our friends in the Mandate? Of course! There's just a bit of paperwork to be done.'
The Ammatar authority spends the rest of their career trying to hack their way through a hell of overlapping, often conflicting corporate jurisdictions and regulations and the whole time corporations merge, split, change rules (sometimes retroactively), and even disappear.
