You mention that other people have quit the job - people resign from a job for a multitude of reasons. How can you be sure that it was due to your bosses personality?
Also you mention that he (I am assuming that the boss is a he) likes the law courts. Why open up that Pandora box?
Why not put it down to a clash of personalities. This happens from time to time. Just move on and look to the future. What is the point of trying to interfere with other peoples judgements?
