After a few years of observing attorneys from the other side, rather than the other end, of the counsel table, I have concluded that courtroom etiquette is the most rapidly declining of all of the social or professional graces. Perhaps this is because the fine points of the art are essentially trivia. Perhaps, on the other hand, the laudable modern trend away from the rigidity of procedure and the pre-trial sanctity of the opposing side's theory of the lawsuit has been carried to the point of dropping the facade of courtesy along with the penetration of the shield of the common counts and facts generally pleaded.
