Changing Senate Rules:
The “Constitutional” or “Nuclear” Option
Summary
Recent reports indicate possible attempts to curtail the use of filibusters in the
Senate, perhaps in the 109th Congress. Some have suggested that proponents of this
idea may invoke something called the “nuclear” or “constitutional” option in Senate
floor procedure to try to end a filibuster without the need for 60 votes or to amend the
cloture rule (Rule XXII) itself. No set definition exists for the term “nuclear” or
“constitutional” in this context. Because the point of using such an option is to
achieve a goal by means lying outside the Senate’s normal rules of procedure, it
would be impossible to list all the different permutations such maneuvers could
encompass. Several likely scenarios that fall into this category are described in this
report, followed by a discussion of the possible advantages and disadvantages of
using such an approach.
Opponents (and some supporters) of this kind of plan typically refer to it as the
“nuclear” option because of the potentially significant result for Senate operations
that could follow from its use. The Senate relies heavily on unanimous consent to
get its legislative work accomplished. It may be more difficult to achieve unanimous
consent in an environment where the minority feels it has lost some of its traditional
rights. Supporters of the concept of majority cloture argue that it is a “constitutional”
option because they will be making their argument based on a constitutional
prerogative or duty of the Senate.
One example of the “constitutional” or “nuclear” option revolves on the
argument that, on the first day of a new Congress, Senate rules, including Rule XXII,
the cloture rule, do not yet apply, and thus can be changed by majority vote. Under
this argument, debate could be stopped by majority vote as well. A Senator would
move the adoption of a new rule or set of rules. The new rule or rules would be
subject to a majority vote, supporters argue, because the mechanics of cloture as set
out in Rule XXII, which requires a supermajority to invoke cloture and end debate,
would not yet apply and the Senate would be operating under general parliamentary
law. One variation would be a claim that on the opening day of a Congress a simple
majority could invoke cloture on the motion to take up a resolution that proposed a
rules change, or on the resolution itself. Again, this scenario would rest on the
proposition that Rule XXII was not yet in force and did not control action. Senators
also could seek to have the 60-vote threshold declared unconstitutional, either for
cloture in general, or only as it applies to Senate consideration of presidential
nominations, or perhaps a subset of such nominations, such as of federal judges.
This scenario might take place in at least two different ways. The presiding officer
might make a ruling from the chair, or a Senator could make a point of order from
the floor that the supermajority requirement for cloture is unconstitutional.
All these possible scenarios would require that one or more of the Senate’s
precedents be overturned or interpreted otherwise than in the past.
This report will be updated as events warrant.

Changing Senate Rules: The
“Constitutional” or “Nuclear” Option
Background
The Senate is governed by the Constitution, the Standing Rules of the Senate,
permanent Standing Orders of the Senate (adopted in prior Congresses), temporary
Standing Orders of the Senate (adopted at the beginning of each Congress), and
statutes. It is also governed by precedents, which are decisions made by the presiding
officer of the Senate, or the body itself, concerning how its rules operate in practice.
The precedents tend to elaborate the Senate’s understanding of its own rules. The
Standing Rules, for example, can be printed in 78 pages, while the most recent
collection of Senate precedents is 1,564 pages long. Precedents have tremendous
weight in deciding parliamentary questions in the Senate, and the presiding officer,
whether the Vice President or a majority party Senator, is expected to be guided by
these precedents when ruling on a pending question.
The Standing Rules of the Senate would seem to be the obvious place to start
if a Senator desired to change that chamber’s procedures. If there is no substantial
opposition, the Standing Rules of the Senate can be changed by a simple majority
vote; there is no supermajority requirement for changing the rules. If, however, there
is opposition to the proposed rules change and if opponents seek to prevent a final
vote on the proposal by extended debate and amendment, known as a filibuster, a
supermajority requirement does exist for invoking cloture, or ending debate, on a
rules change. Senate Rule XXII, which sets out the process for invoking cloture,
requires that two-thirds of those present and voting (67 if all Senators participate)
vote to invoke cloture on a rules change.
This is a difficult threshold to meet; invoking cloture on all other measures or
matters requires a three-fifths vote of all Senators chosen and sworn (60 votes, if no
vacancies exist). Cloture on a proposal to change an existing Standing Order, or to
establish a new Standing Order, also requires this lower threshold. It should be noted
that the Senate uses Standing Orders to modify or set aside its standing rules without
doing so directly. S. Res. 445, in the 108th Congress, for example, inherently
superceded portions of Senate Rule XXV and Senate Rule XXVI, to establish a
committee on Homeland Security and Governmental Affairs without directly
amending the rules. A similar approach might be used to alter Rule XXII without
directly amending it.
The potential difficulty the elevated requirement for invoking cloture poses for
changing the Standing Rules, has led some to look at making changes in Senate
practice through proceedings that alter existing precedents or establish new ones.
Proceedings of this kind, it is argued, would both break old precedent and establish
new Senate precedents, and could have the effect of changing Senate practice.

CRS-2
Eventually such a plan might even result in changes in Senate rules, while
circumventing the procedures prescribed by Senate rules for changing the rules.

Some have recently referred to such actions as the “nuclear option” for bringing
about change in Senate rules or practice, referring to the possible problems that could
result in the Senate from the use of such tactics. No set definition exists for the term
“nuclear option”; indeed, this term has been used to refer to many kinds of possible
proceedings. One set of variants, however, involves appealing to constitutional
requirements as an authority superior to that of the Senate’s own rules, and
supporters of such an approach have accordingly preferred to describe such an
approach as a “constitutional option.”1
Particularly in the 108th Congress, the majority party expressed frustration at its
inability to end filibusters to secure votes to confirm some federal judges.2 In the
108th Congress, Senate Majority Leader Bill Frist proposed to change the Senate’s
rules regarding debate on presidential nominations. His resolution (S.Res. 138)
would have changed Rule XXII, by imposing an ever-decreasing threshold for
successive votes to invoke cloture on a nomination, until it could be achieved by a
majority vote of the full Senate. Because this resolution would change the Standing
Rules of the Senate, a two-thirds vote of those Senators present and voting would be
needed to invoke cloture if it were filibustered on the Senate floor.3
Senator Frist stated on the Senate floor on the first day of the 109th Congress that
he wants to ensure each judicial nomination receives an up or down vote by the full
Senate, and he noted that he might seek the change of Senate procedures to do this.
This followed comments to several news organizations that he might use the start of
the 109th Congress as an opportunity to use some version of a “constitutional” option
to change Senate rules to block the filibuster of judges.4

Possible Courses of Action
Exactly because the point of a “nuclear” or “constitutional” option is to achieve
changes in Senate procedure by using means that lie outside the Senate’s normal
rules of procedure, it would be impossible to list all the different permutations such
maneuvers could encompass. The following, nevertheless, represent four different
approaches or scenarios that have been discussed as possible methods to achieve this
goal. These are just a sampling of the options available to Senators; they are not an
exhaustive list.
Opening Day5 Scenario One — Majority Rules Change
The Senate has long considered itself a continuing body. Consistent with this
premise, the practice of the Senate has been not to re-adopt rules in a new Congress.
There has been debate about whether the rules that govern the Senate in one
Congress should continue in effect to the next Congress. Supporters of this position
argue that, because only one-third of the membership of the Senate changes at any
one time, and a quorum of the Senate is always in existence, the body does not need
to reconstitute itself at the beginning of each Congress and, thus, the existing rules
continue in effect from one Congress to the next. Opponents of this position,
however, point out that under these conditions, any change in rules must be
considered under the existing rules, which can make changing the rules extremely
difficult. They contend that this “entrenchment” of the rules unconstitutionally
inhibits the Senate from exercising its constitutional authority to determine its own
rules.
Those who would seek to amend Senate rules or end a filibuster by a majority
vote might use the first day of a new Congress to advance their proposal, arguing that
Senate rules, particularly the cloture rule, Rule XXII, did not apply yet, and thus that
debate could be ended by majority vote. Under this scenario, a Senator would move
the adoption of a new rule or set of rules, which could contain changes to Rule XXII
— or any other rule the Senator wanted to change. Debate on the new rule or rules
could be limited, subject to a majority vote, supporters argue, because the mechanics
of cloture as set out in Rule XXII would not yet apply and the Senate would be
operating under general parliamentary law. Senate acceptance of these conditions
would allow decisions to be made by majority vote and could permit the use of
parliamentary devices to end debate, such as calling for the previous question, that
would be decided by majority vote.6 In order for this situation to prevail, the
5 Opening day would not necessarily mean one calendar day. In the past, the Senate has
counted the opening day as a legislative day, not as a calendar day. A legislative day lasts
until the Senate adjourns at the end of a day of business; if the Senate recesses daily instead
of adjourning, the same legislative day continues, no matter how many calendar days pass.
So, in theory, the opening day of the Senate could last any number of calendar days, until
the Senate adjourned for the first time at the end of a daily session.
6 In current American parliamentary practice, the previous question is a nondebatable motion
to close consideration and bring a pending matter to an immediate vote, used extensively in
the House of Representatives. If the motion is agreed to by a majority vote, it generally cuts

presiding officer would have to rule that the previously existing rules did not govern
consideration of a motion to change the rules offered under these conditions, and the
Senate would have to endorse that ruling, most likely by tabling an appeal of the
ruling, which requires a simple majority vote to succeed.
This was the situation on the opening day of the 85th Congress, on January 3,
1957, when Senator Clinton Anderson moved to consider a new package of rules.
Vice President Richard Nixon, as presiding officer, said during debate that he
believed that the Senate could adopt new rules “under whatever procedures the
majority of the Senate approves.” Vice President Nixon added that he did not believe
the Senate was bound by any previous rule “which denies the membership of the
Senate the power to exercise its constitutional right to make its own rules.” Vice
President Nixon made it clear that this was his personal opinion, not a ruling from
the chair. The Senate, however, tabled Senator Anderson’s motion. Senator
Anderson made a similar attempt at the beginning of the 86th Congress. This time,
the Senate voted to send the proposed rules changes to committee, not reaching any
conclusion about changing rules on the first day.7
In 1967, at the start of the 90th Congress, however, Senator George McGovern
proposed that the Senate vote on a motion to consider a resolution lowering the
threshold for invoking cloture. He said that under the Constitution, the Senate has
the right to adopt new rules by majority vote. Senator Everett Dirksen then raised a
point of order that Senator McGovern’s motion would circumvent existing Senate
rules. The presiding officer, Vice President Hubert Humphrey, ruled that, because
Senator Dirksen’s point of order raised a constitutional issue, the Senate itself should
rule on whether the point of order should be sustained. Under Senate precedents, the
presiding officer may not rule on a constitutional point of order and instead must
submit the point of order to the full Senate for a vote.8 Humphrey also ruled that the
point of order was subject to a tabling motion, which was not debatable. Senator
McGovern moved to table the point of order, and by a vote of 37-61 the Senate
refused to table it. The Senate then voted 59-37 to sustain the point of order.9
In sum, Vice President Hubert Humphrey submitted the constitutional point of
order to the Senate, and Senator McGovern moved to table it. The Senate failed to
table, or kill, the point of order. The Senate then voted 59-37 to sustain the point of
order that Senator McGovern’s motion would circumvent existing Senate rules.
6 (...continued)
off further debate and prevents the offering of additional amendments or motions. In its
early history, the Senate used a motion for the previous question as a way to avoid
consideration of controversial subjects. It was not the same motion as understood today.
It was deleted from Senate rules in 1806. Neither version of the previous question is
permitted under current Senate rules.

With that vote, the Senate declined to allow the original motion to change the rules
made by Senator McGovern.
To employ the “nuclear” or “constitutional” option in this scenario, the Senate
would have to overturn these two precedents, perhaps among others.
Opening Day Scenario Two — Majority Cloture
A variation on the first proposition would rest on a claim by proponents of
changing Senate rules that on the opening day of a Congress a simple majority could
invoke cloture on the motion to take up a resolution that proposed a rules change, or
on the resolution itself. As in the first opening day scenario, this action would be
based on the premise that even if, in contrast to the previous option, Senate rules
were regarded as continuing in effect, the Senate must, at the start of a new Congress
in particular, be able to exercise effectively its constitutional power over its own
rules. Therefore, supporters of this approach argue, the Senate must be able to reach
a vote on questions of adopting or amending these rules.
At the start of the 91st Congress (1969-1971), this approach was attempted, and
the presiding officer, Vice President Hubert Humphrey, ruled that a majority of those
Senators present and voting could invoke cloture. The question before the Senate
when Humphrey made this ruling was a motion to consider a resolution to change the
threshold for invoking cloture from two-thirds to three-fifths of those present and
voting. In this case, the Senator who sought to change the rules by majority vote,
Senator Frank Church, asked the presiding officer to make the determination, and the
Vice President then ruled. The Senate voted 51-47 to invoke cloture, and the chair
ruled that the motion had succeeded by majority vote. Later the same day, the Vice
President’s ruling was appealed and the Senate voted 45-53 to overrule it, thus
overturning the decision to permit majority cloture.10
In 1975, at the start of the 94th Congress, proponents of the proposition that a
majority of Senators could invoke cloture on a rules change at the opening of a
Congress had a short-lived victory. Senator James Pearson submitted a resolution
changing the threshold for invoking cloture from two-thirds of those present and
voting to three-fifths of those present and voting. The Senator offered a lengthy
motion, which included as a given that a majority vote of the Senate could invoke
cloture on his proposal. Senator Mike Mansfield objected and raised a point of order
that Senator Pearson’s motion violated the rules of the Senate. The presiding officer,
Vice President Nelson Rockefeller, declined to rule, on the same ground cited by
Vice-President Humphrey in 1967, instead putting the question before the Senate to
decide. By a vote of 51-42, the Senate agreed to a motion to table the Mansfield
point of order, thus implicitly agreeing to the majority cloture proposition. Because
Senator Pearson’s motion was so lengthy, however, the chair ruled that it could be
divided into individual pieces for debate. This debate occupied the Senate for days,
10 Ibid., p. 28; Vice President Hubert Humphrey, remarks in Senate, Congressional Record,
vol. 115, Jan. 16, 1969, pp. 994-995.

CRS-6
preventing Members from reaching a final vote on the rules change, which could
have had the effect of settling whether a majority could invoke cloture.11
Less than two weeks later, the Senate reconsidered the vote by which it tabled
Senator Mansfield’s point of order, and then voted 53-43 to sustain it. That same
day, as a part of the compromise by which the Senate reversed itself on the point of
order, Senator Robert C. Byrd offered a series of motions that ended with the Senate
adopting a change to the cloture rule, altering the required vote to the present
standard of a three-fifths majority of those chosen and sworn (except on propositions
to change the Standing Rules).12
Thus, the Senate briefly endorsed majority cloture, but later reversed itself and
re-established the precedent that the rules are continuous.
Disagreements remain about whether the Senate obliterated the precedent of
majority cloture with its subsequent actions. Senator Byrd has said he believes the
vote “erased the precedent.”13 Former Vice President Walter Mondale, however,
who was involved in the debate as a Senator, has said he believes “the Rule XXII
experience was significant because for the first time in history, the Vice President
and a clear majority of the Senate established that the Senate may, at the beginning
of a new Congress and unencumbered by the rules of previous Senates, adopt its own
rules by majority vote as a constitutional right. The last minute votes attempting to
undo that precedent in no way undermine that right.”14
Successful employment of this scenario would involve the Senate overriding its
later 1975 decision sustaining the point of order against majority cloture, and instead
reaffirming its initial implicit decision of that year in favor of majority cloture.
The Constitution and Cloture
Another set of options for altering the requirement for cloture would involve
addressing the matter not on the opening day of a new Congress, but in the course of
the session. The intent of this set of options would be to have the 60-vote threshold
for cloture declared unconstitutional, either for cloture in general, or only as it
applied to Senate consideration of presidential nominations, or perhaps a subset of
such nominations such as of federal judges.
Under Senate precedents, the presiding officer does not rule on a hypothetical
situation, so it is likely that for options of this kind to be used, a nomination would
have to be before the Senate, and the Senate would have to have failed to invoke
cloture on the nomination.

CRS-7
At this point, the scenario could play out in at least two different ways. It has
been suggested that the presiding officer, probably the Vice President or the President
pro tempore, could declare Rule XXII unconstitutional, set the supermajority
threshold aside, and rule that cloture could be invoked by a simple majority. This
ruling itself would constitute a break with Senate precedents, which, as discussed
above, rely on the Senate as a whole to decide constitutional issues. If the chair
issued such a ruling, opponents would likely appeal, and the appeal would ordinarily
be debatable.15 Another Senator, however, could move to table the appeal, which
would be a non-debatable motion. If the Senate voted to table the appeal of the
ruling, a question which would be decided by a simple majority, the appeal would fail
and the new precedent would appear to be confirmed, permitting cloture to be
invoked by simple majority, if the majority could get to that vote.
Under a second scenario, following a vote in which the Senate failed to invoke
cloture on a pending measure or matter, a Senator would, from the chamber floor,
make a constitutional point of order that the supermajority requirement for cloture
is unconstitutional. The presiding officer might then, in keeping with precedent,
submit the constitutional question to the Senate for its decision. Because a
procedural question submitted to the Senate traditionally is debatable, and the point
of the exercise according to its supporters is to find a way to limit debate, however,
the presiding officer could break with precedent by ruling that the motion would not
be debatable. It is likely that a Senator would appeal the decision of the chair that the
question would not be debatable, and this appeal probably would be met with a
counter motion to table the appeal. If the tabling motion were successful, the appeal
would fall, with the effect of sustaining the ruling of the chair. Pursuant to the ruling
that the submitted point of order was not debatable, the Senate would then proceed
to vote, without debate, on the constitutional question, which would be decided by
a simple majority vote.
Employment of either of these versions of the “constitutional option” would
require the chair to overturn previous precedent, either by ruling on a question that
by precedent has been submitted to the Senate, or by ruling non-debatable a question
that by precedent has been treated as debatable.
Considerations
Any version of the “nuclear” option would carry with it risks and rewards. The
most obvious direct benefit would be for those judges who could be confirmed by
majority vote if debate could be stopped by a simple majority as well. It would also
strengthen the executive branch’s hand in the selection of federal judges, if the
Administration could be assured of confirmation with the votes of 51 Senators. It
also might make the Administration less likely to use its recess appointment power
15 Riddick, Senate Procedure, p. 148.

CRS-8
to install judges on the federal bench, an issue that raised serious concerns in the
Senate in 2004.16
Potential Implications for the Senate
Opponents of using any of these parliamentary maneuvers argue that the ability
to confirm nominations, even those with significant opposition, by a simple majority
could make an Administration less willing to negotiate with the Senate and weaken
the role of the Senate in the nomination and confirmation of presidential nominees.
Furthermore, they note that the Senate confirmed 207 of President Bush’s judicial
nominations and failed to confirm 10. In the 108th Congress, roughly 3% of federal
judgeships have been vacant at any time, not creating a significant impediment to the
operations of the federal courts, they say. 17
Supporters of using a “nuclear” or “constitutional” option to change the cloture
rule argue that it could protect a Senate majority’s ability to act, particularly when it
came to an issue of such vital interest as ensuring a sufficient number of federal
judges to operate the courts, the third branch of the federal government. There is a
serious concern among some that a constitutional responsibility of the Senate, to
advise and consent to presidential nominations, is being weakened with the repeated,
successful filibusters of certain federal judicial nominations.18
Because the Senate has not utilized the “nuclear” or “constitutional” option
before, the consequences of doing so are unclear. The potential exists for significant
repercussions. In describing the Senate, most modern congressional scholars now
refer to it as a “unanimous consent body.” By far the greatest share of the chamber’s
business is conducted, one way or another, by agreement among all Senators. In part,
the reason is that Senators have learned to agree on how to proceed, knowing that
such procedural agreement does not necessarily predetermine the outcome of policy
decisions. The use of a plan which would intentionally use a procedural tool to force
a final decision on a policy option could make it dramatically more difficult to obtain
unanimous consent for anything else that followed.
Both sides of the debate seem to be concerned about the possible results. In the
opinion of one Democratic Senator, the use of the “nuclear” option “… would be a
dagger at the heart of what the Senate is all about, and Democrats would take very
strong action.”19 A Republican Senator told The Hill that damage from the use of the
“nuclear” or “constitutional” option could level the Senate, making it very difficult
for work to get done. “The nuclear option on judges, it rather clears the landscape,”
the Senator said.20

The procedural maneuver also could change the nature of the Senate, in which
it is difficult to override the rights of the minority. It would raise fundamental and
significant questions about how the institution would function, the answers to which
would become clear only as time passed. If the power of the filibuster were broken,
for example, would the Senate become more like the House of Representatives, in
which debate and deliberation can be terminated at the option of the majority? Or
would it become a chaotic environment in which a temporary majority could change
precedents any time it wanted to?
Another concern would be consequences for other rules of the Senate. Because
it is so difficult to change the Senate’s rules, they have remained fairly stable, and
therefore the basic structure of Senate procedure has remained fairly constant. If,
however, a change to the rules were accomplished by a majority vote, nothing would
prevent other changes to the rules from being proposed, which could then
conceivably be accomplished with a majority vote to end debate on them as well.
In addition, even if a “constitutional” or “nuclear” option were used, opponents
still might be able to delay a final vote on whatever measure or matter was pending.
Existing Senate precedents would seem to allow an endless series of amendments to
a proposed rules change, even if no debate were allowed. The Senate routinely does
this each year when it considers the annual budget resolution. Therefore, it is unclear
that the “constitutional” or “nuclear” option by itself could bring about a vote on a
rule change. Further, even if the use of this option resulted in a lower cloture vote
threshold, other portions of the rule would presumably remain untouched, in which
case the post-cloture process still would provide delaying possibilities for opponents.
Additional questions arise if the Senate used an opening day gambit. Would
successful action in this form change the understanding of the Senate as a continuing
body? Would this change mean that the Senate would have to elect its officers and
adopt its rules at the start of each Congress?
Alternative Proposal
One potential alternative would be to modify other Senate practices (instead of
changing the cloture rule) or to enforce existing Senate rules more stringently. A
number of possible approaches could be used to bring debate to a close absent any
formal change to Rule XXII.

For example, the Two-Speech Rule does not apply to executive business in the
same way it does to legislative business. Limiting senators to two speeches during
the consideration of any nomination, regardless of how many session days the
nomination was pending, would bring about a vote on a nomination without the need
to invoke cloture, or to consider amendments to the cloture rule.

Another alternative might be to require Senators who wish to filibuster a
measure or matter (such as a nomination) to hold the floor and talk to maintain their
filibuster. In the modern Senate, such displays are rare. Instead, the Senate routinely
permits Senators to “suggest the absence of a quorum” as a means to delay action
without the need to debate. The Senate, by precedent, has ruled such quorum calls
dilatory, after cloture. By precedent, the Senate could make such quorum calls

CRS-10
dilatory at any time, if no substantive business had intervened since a quorum had
been previously established.
The two-track system allows other business to come before the Senate even as
the pending business remains unresolved. As a result, time on the Senate floor is
more often used to conduct business on which there has already been agreement,
rather than to debate or amend measures, or filibuster them. Removing a contentious
measure from active consideration allows the threat of a filibuster to halt a measure,
instead of requiring opposition Senators to openly debate the measure and explain
their concerns publicly.
The Senate no longer relies on extended continuous session to put pressure on
opposition Senators. Such late-night or multiple day sessions were common until a
generation ago. The disuse of a traditionally effective strategy to end debate or to
encourage policy compromise has led, in the opinion of some, to the consideration
of ill-advised rule changes when less drastic changes to Senate tradition could
achieve the desired result.21
