Clients, not lawyers, are the litigants. Whatever may be the ill-feeling existing between clients, it should not be allowed to influence counsel in their conduct and demeanor toward each other or toward suitors in the case. All personalities between counsel should be scrupulously avoided. In the trial of a cause it is indecent to allude to the personal history or the personal peculiarities and idiosyncrasies of counsel on the other side. Personal colloquies between counsel which cause delay and promote unseemly wrangling should also be carefully avoided.
