For this reason, the Senate routinely chooses to set aside its standing rules by unanimous consent. Under recent practice, these UC agreements sometimes include a provision imposing a 60-vote requirement for approval of amendments or legislation, instead of the simple majority vote ordinarily required in the Senate. These amendments or measures are sometimes of a controversial nature with potential to be subjected to extended consideration or even a filibuster. By incorporating a 60-vote threshold, such UC agreements avoid the multiple requirements associated with Senate Rule XXII, both for invoking cloture and for consideration under cloture. Such UC agreements ensure that a measure will not be successful without the same level of super-majority support that would be required for cloture by stipulating that if the 60-vote threshold is not reached, the matter will be disposed of. Unanimous consent agreements that impose a 60-vote threshold may be agreed to at any time, either in advance, or during consideration.
The Senate frequently enters into unanimous consent agreements (sometimes referred to as "UC agreements" or "time agreements") that establish procedures for the consideration of legislation that the Senate is considering or will soon consider. In recent practice, such unanimous consent agreements have sometimes included a provision that would require a 60-vote threshold to be met for amendments or legislation to be considered agreed to, rather than the simple majority ordinarily required. These amendments or measures may be of a controversial nature with the potential for causing a filibuster. By incorporating a 60-vote threshold, such UC agreements avoid the multiple requirements imposed by Senate Rule XXII for invoking cloture, while preserving the same requirement for super-majority support.
