Black's Law Dictionary
Lat. in Roman law. The form of words by which a vote in favor of a proposed law was orally expressed. Uti rogas, volo vel jubeo, as you ask, I will or order; I vote as you propose; I am for the law. The letters "U. R." on a ballot expressed the same sentiment.
Adame, Rom. Ant. 98, 100.
