Rule 51. Exceptions Unnecessary

Exceptions to ruling or orders of the court are unnecessary. For all purposes for which an exception has heretofore been necessary it is sufficient that a party, at the time the court ruling or order is made or sought, makes known to the court the action which he desires the court to take or his objection to the court's action and the grounds therefor. But if a party has no opportunity to object to a ruling or order, the absence of an objection does not thereafter prejudice him.
