1995: Hutchison precedent Rule XVI of the Standing Rules of the Senate prohibits legislative material from being included in
general appropriations bills. In 1995, during consideration of the Emergency Supplemental Appropriations and Rescissions for the Department of Defense to Preserve and Enhance Military Readiness Act of 1995, Senator
Kay Bailey Hutchison offered an amendment that would have changed existing law regarding endangered species, therefore violating Rule XVI. Senator Harry Reid raised a point of order against the amendment, which the chair sustained. Hutchison appealed the ruling of the chair. The Senate voted against sustaining the decision of the chair by a vote of 42–57. The Senate thus set a precedent nullifying the provision of Rule XVI. In 1999, the Hutchison precedent was overturned (and the original effect of Rule XVI restored) when the Senate agreed to , which states:
Resolved, That the presiding officer of the Senate should apply all precedents of the Senate under rule 16, in effect at the conclusion of the 103d Congress.
1996: FedEx precedent Rule XXVIII, paragraph 3, of the Standing Rules of the Senate prohibits any matter outside the scope of a
conference from being included in a conference report. In 1996, during consideration of the conference report on the Federal Aviation Reauthorization Act of 1996, Majority Leader Trent Lott raised a point of order that the conference report exceeded the scope of the conference with respect to provisions relating to
FedEx. After the point of order was sustained by the chair, Lott appealed the ruling of the chair. The Senate voted against sustaining the decision of the chair by a vote of 39–56. The Senate thus set a precedent nullifying the provision of Rule XXVIII.SEC. 903. Beginning on the first day of the 107th Congress, the Presiding Officer of the Senate shall apply all of the precedents of the Senate under Rule XXVIII in effect at the conclusion of the 103d Congress.
2013: Cloture on nominations On November 21, 2013, Majority Leader Harry Reid raised a point of order that "the vote on cloture under Rule XXII for all nominations other than for the Supreme Court of the United States is by majority vote." The presiding officer overruled the point of order, and the Senate voted 48–52 against sustaining the decision of the chair. The Senate therefore set a precedent that cloture can be invoked on nominations (except to the Supreme Court) by a simple majority, even though the plain text of the rule requires "three-fifths of the senators duly chosen and sworn" to invoke cloture. Three Democrats (
Carl Levin,
Joe Manchin and
Mark Pryor) voted with all Republicans in favor of sustaining the decision of the chair. The text of Rule XXII was never changed. Although the 60-vote threshold was eliminated for most nominations, nominations are still susceptible to being delayed by filibusters, and 60 votes were still required to invoke cloture on other questions such as legislation and Supreme Court nominations.
Rationale for change The Democrats' stated motivation for this change was the perceived expansion of filibustering by Republicans during the Obama administration, in particular blocking three nominations to the
United States Court of Appeals for the District of Columbia Circuit. Republicans had asserted that the D.C. Circuit was underworked, At the time of the vote, 59 executive branch nominees and 17 judicial nominees were awaiting confirmation. Prior to November 21, 2013, there had been only 168 cloture motions filed (or reconsidered) with regard to nominations. Nearly half of them (82) had been during the Obama administration. However, those cloture motions were often filed merely to speed things along, rather than in response to any filibuster. In contrast, there were just 38 cloture motions on nominations during the preceding eight years under President
George W. Bush. Most of those cloture votes were successful. Obama won Senate confirmation for 30 out of 42 () federal appeals court nominations, compared with Bush's 35 out of 52 (). Regarding Obama's
federal district court nominations, the Senate approved 143 out of 173 () as of November 2013, compared to George W. Bush's first term 170 of 179 (), Bill Clinton's first term 170 of 198 (), and George H.W. Bush's 150 of 195 (). Filibusters were used on 20 of Obama's nominations to district court positions, but Republicans had allowed confirmation of 19 out of the 20 before the nuclear option was invoked.
2017: Cloture on Supreme Court nominations On April 6, 2017, the Republican-majority Senate invoked the nuclear option and voted 48–52 along party lines against sustaining the decision of the chair on a point of order raised by Majority Leader
Mitch McConnell, thus removing the
Supreme Court exception created in 2013. This established a new precedent which allowed cloture to be invoked on Supreme Court nominations by a simple majority. The vote came after Senate Democrats filibustered the
nomination of Neil Gorsuch to the
Supreme Court of the United States.
2019: Postcloture time on low-level nominations On April 3, 2019, in response to a perceived increase in postcloture filibusters by Senate Democrats on President
Trump's executive and judicial nominations, the Republican-majority Senate voted 51-49 to overturn a ruling of the chair and thus set a precedent that postcloture debate on nominations—other than those to the
Supreme Court of the United States, to the
United States courts of appeals and to positions at Level I of the
Executive Schedule—is two hours. All Republicans except Senators
Susan Collins and
Mike Lee voted against sustaining the decision of the chair.
2025 instances called "nuclear" Senate Democrats accused the Republican majority under Majority Leader
John Thune of exercising the nuclear option three times in 2025: • to allow consideration of joint resolutions of disapproval under the
Congressional Review Act, • to allow the use of a current policy
budget baseline for scoring of the
One Big Beautiful Bill Act, and • to allow the consideration in
executive session of a resolution allowing the Majority Leader to move to proceed to the en bloc consideration of multiple nominations. ==Proposed use for legislation==
