The unanimous approval agreements put the order and structure of the land economy in order and speed up the legislative process. They can be as simple as a request to waive a quorum request, or as complicated as a binding contract resulting from a longer and often lively debate. Since 1789, senators have been doing routine business by unanimous consensus, but the more formal agreement of the UC dates back to the 1840s, when Senator William Allen of Ohio sought a method to end the debate. Some rights can only be abandoned unanimously. For example, in disciplinary proceedings, only one member may require that the vote on the imposition of a sanction be by ballot.  On April 13, 1846, Allen returned to the floor. A vote on the Oregon issue is inevitable, he argued, so why not “approve the exact day the Senate votes.” Such a measure would be acceptable, said James Morehead of Kentucky, “provided it is not considered a precedent.” But he set a precedent. Senators agreed on a consensus and unanimously agreed to close the debate and declare a vote. In June, the Senate approved the contractual decisions, a territory was created, and in 1859, Oregon became our 33rd state. Scientists believe this is the first example of the Senate adopting a formal agreement on the UC.
Objections are sometimes used as a delaying tactic. The opponent cannot agree with the proposal under consideration, but chooses to object in order to impose a formal vote that takes time and may include a period of debate.  Soon such pacts were commonplace, but until the 20th century they remained only a gentleman`s agreement. As one presiding official lamented, they could be “injured with impunity” by any senator. As a result, in January 1914, the Senate adopted a new rule that unanimous approval agreements “must function as an ordinance of the Senate” and can only be amended by another UC agreement. Understand the potential of this procedural tool, the revised LBJ UC agreements to govern the entire legislative process – to frame the debate, limit changes, plan a vote and strengthen the strength of its own majority leadership. Unanimity is often used to approve the protocol.  If no correction has been made to the minutes, they are unanimously approved without formal agreement.  In this particular case of unanimous approval, there can only be opposition to the approval of the minutes if a correction is made.  The unanimous adjective comes from the same Latin word unanimus, which means “a spirit.” So if people think unanimously, they all have the same idea in mind.
