By 51 votes to 8, the Senate adopted Article XII.20 Two critical parts of the rule provide that (1) unanimous approval agreements are orders of the Senate, which means that the presidential official is responsible for ensuring the execution of his or her mandate; and (2) The Senate could unanimously amend a unanimous approval. As an order of the Senate, unanimous approval agreements are now printed in the Senate newspaper. (They are also printed in the daily calendar of Senate business, as noted above, and in the minutes of Congress.) There is a fundamental difference between the Senate, which works under a unanimous approval agreement, and the Senate, which works under the Standing Rules. While Senate rules allow for virtually unlimited debates and very few restrictions on the right to amend, these agreements generally limit the time for debate and the right of senators to propose amendments.2 Many consultative assemblies (e.g. B City Councillors) use a procedure known as the “approval program.” Issues considered uncontested are on the approval agenda and are all adopted by a single proposal. When a member objects to one or more points of the approval program, the contested points are removed from the approval program and dealt with in the normal course. As a general rule, at a meeting of an advisory assembly, operations are carried out according to a formal procedure of voting, debate and voting. However, if there is no objection, action could be taken unanimously.      The unanimous approval procedure is used to expedite activity by removing the need for formal votes on routine issues on which consensus is likely.
 The underlying principle is that procedural safeguards can be waived to protect a minority if there is no minority of shooters.  Some rights can only be waived unanimously. For example, in disciplinary proceedings, only one member may require that the vote on the imposition of a sanction be by ballot.  Complex agreements create a tailor-made procedure for virtually everything the Senate accepts, such as bills, joint resolutions, simultaneous resolutions, simple resolutions, amendments, appointments, contracts or conference reports. As two members of the Senate have written, in parliamentary procedure, unanimous approval, even if usually solitary, or in the case of Westminster parliaments, leaves the House (or exit from the Senate), a situation where no member opposes a proposal. 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.
 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. That is why, in January 1914, the Senate adopted a new rule that unanimous approval agreements “work as an order of the Senate” and can only be amended by another UC agreement.
