The lawyer role would be very situational and would give the CL something to do on rounds where they get "shit down" by the CO and command. It'd also add some potential for shady stuff as well.
The court is a decent idea, however the issue with such mechanics is. If they're a requirement. They can get a bit sticky when things are a bit hectic.
It's always best to base the general game design as "Will this survive cm at its most hectic." and unfortunately slow paced things (which I do enjoy) rarely do in practice and are better summoned in quieter or longer rounds. If you want to hit me up on discord, I could go in to greater depth but I won't fill up too much more of this thread with the hypertheticals.
