The Chancellor may dispense with argument in any action. He may require counsel to argue or brief the law and facts, either or both, in any action, and shall not be bound to decide the same until that duty has been performed to his satisfaction. In all cases counsel must be prepared to argue the case as soon as the taking of the testimony is concluded. The Chancellor may specify the points of law or fact on which he desires argument and regulate the order and limit the length of oral arguments. In all cases where briefs are requested by the Chancellor, copies thereof must be delivered in person or by mail to opposing counsel. Any negligent or willful failure on the part of counsel to fully argue or brief any question when requested by the Chancellor will be considered a grave discourtesy.
