The Chair may obtain unanimous approval if he or she asks if there are any objections to anything. For example, the chair may say, „If there are no objections, the motion will carry. [Pause] As there are no objections, the request is accepted.  In Westminster parliaments, the sentence could be: „There are no objections, permission is granted. In the most common cases, such as inserting an article into the minutes of Congress in Congress, the president may shorten that statement to four words: „Without objection, so arranged“ or even in two words: „Without objection“ (Latin: nemine contradicente). Another example of this practice in the House of Representatives is when a series of votes have been interrupted by a speaker or another company. The Chair will say, „Without objection, the five-minute vote will continue. In short, uncertainties and controversies influenced the Senate on January 16, 1914, to adopt a formal rule governing unanimous consent agreements. Article XII has had relatively little discussion. The great controversy concerned whether these covenants could be modified by another unanimous consent agreement. It is not surprising that Senator Lodge opposes the new rule, as the approval of subsequent amendments to unanimous consent agreements would only result in delays in expediting the work of the Senate.
Senator Charles Thomas, D-CO, replied, „It seems to me that it is the most illogical thing in the world to say that the United States Senate can unanimously approve something and, by this law, deprives itself of the power to unanimously agree to undo it.“ 19 Senators generally accept the debate and amendment restrictions common to most unanimous consent agreements for two overlapping reasons: they facilitate the management of the Senate`s workload and serve the interests of individual legislators. Concluded on the basis of trust and after lengthy negotiations, unanimous consent agreements are the equivalent of „binding contracts“ that can only be amended or modified by unanimous consent. Sometimes unanimous approval can be presumed if the Chair feels that no one would raise an objection if he formally requested it.  For example, if it is obvious that members of an assembly are listening to a speaker who has exceeded the debate deadlines but is about to be completed, the Chair may allow the speaker to continue without interruption.  Senator Reed Smoot, R-UT, was surprised when a unanimous consent agreement was reached, which he rejected. .
