Vt. R. Crim. P. 51
Formal exceptions to rulings or orders of the court are unnecessary; but for all purposes for which an exception has heretofore been necessary it is sufficient that a party, at the time the ruling or order of the court is made or sought, makes known to the court the action which he desires the court to take or his objection to the action of the court and the grounds therefor; and, if a party has no opportunity to object to a ruling or order at the time it is made, the absence of an objection does not thereafter prejudice him. Subsequent objection to the same legal point shall be unnecessary, and the admission or exclusion of evidence of like nature thereafter shall be deemed to be subject to the same objection as originally stated.
