In Klemm v. Superior Court (1977) 75 Cal.App.3d 893, the court made this cogent observation: "Though an informed consent be obtained, no case we have been able to find sanctions dual representation of conflicting interests if that representation is in conjunction with a trial or hearing where there is an actual, present, existing conflict and the discharge of duty to one client conflicts with the duty to another. As a matter of law a purported consent to dual representation of litigants with adverse interests at a contested hearing would be neither intelligent nor informed. Such representation would be per se inconsistent with the adversary position of an attorney in litigation, and common sense dictates that it would be unthinkable to permit an attorney to assume a position at a trial or hearing where he could not advocate the interests of one client without adversely injuring those of the other ."
