Supreme Court Appointment Process: Senate Debate and Confirmation Vote

Summary
The procedure for appointing a Justice to the Supreme Court is provided for in the U.S.
Constitution in only a few words. The “Appointments Clause” in the Constitution (Article II,
Section 2, clause 2) states that the President “shal nominate, and by and with the Advice and
Consent of the Senate, shal appoint ... Judges of the supreme Court.” While the process of
appointing Justices has undergone some changes over two centuries, its most essential feature—
the sharing of power between the President and the Senate—has remained unchanged: To receive
lifetime appointment to the Court, one must first be formal y selected (“nominated”) by the
President and then approved (“confirmed”) by the Senate.
For the President, the appointment of a Supreme Court Justice can be a notable measure by which
history wil judge his presidency. For the Senate, a decision to confirm is a solemn matter as wel ,
for it is the Senate alone, through its “Advice and Consent” function, without any formal
involvement of the House of Representatives, that acts as a safeguard on the President’s
judgment. This report provides information and analysis related to the final stage of the
confirmation process for a nomination to the Supreme Court—the consideration of the
nomination by the full Senate, including floor debate and the vote on whether to approve the
nomination.
Traditional y, the Senate has tended to be less deferential to the President in his choice of
Supreme Court Justices than in his appointment of persons to high executive branch positions.
The more exacting standard usual y applied to Supreme Court nominations reflects the special
importance of the Court, coequal to and independent of the presidency and Congress. Senators are
also mindful that Justices—unlike persons elected to legislative office or confirmed to executive
branch positions—receive the opportunity to serve a lifetime appointment during good behavior.
The appointment of a Supreme Court Justice might or might not proceed smoothly. From the
appointment of the first Justices in 1789 through its consideration of nominee Brett Kavanaugh in
2018, the Senate has confirmed 119 Supreme Court nominations out of 163 received. Of the 44
nominations which were not confirmed, 12 were rejected outright in roll-cal votes by the Senate,
while nearly al of the rest, in the face of substantial committee or Senate opposition to the
nominee or the President, were withdrawn by the President, or were postponed, tabled, or never
voted on by the Senate. Six of the unconfirmed nominations, how ever, involved individuals who
subsequently were renominated and confirmed.

confirmation process for nominations to the Supreme Court. For a report related to the selection

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

Introduction
The procedure for appointing a Justice to the Supreme Court of the United States is provided for
by the Constitution in only a few words. The “Appointments Clause” (Article II, Section 2, clause
2) states that the President “shal nominate, and by and with the Advice and Consent of the
Senate, shal appoint ... Judges of the supreme Court.” The process of appointing Justices has
undergone changes over two centuries, but its most basic feature—the sharing of power between
the President and Senate—has remained unchanged. To receive an appointment to the Court, a
candidate must first be nominated by the President and then confirmed by the Senate. This report
provides information and analyses related to the debate and consideration of Supreme Court
nominations by the full Senate once nominations are reported by the Judiciary Committee.1
Criteria Used by Senators to Evaluate Nominees
Once the full Senate begins debate on a Supreme Court nomination, many Senators typical y wil
take part in the debate. Some, in their remarks, underscore the importance of the Senate’s “advice
and consent” role, and the consequent responsibility to carefully determine the qualifications of a
nominee before voting to confirm.2 Typical y, each Senator who takes the floor states his or her
reasons for voting in favor of or against a nominee’s confirmation.
The criteria used to evaluate a Supreme Court nominee are an individual matter for each Senator.
In their floor remarks, some Senators may cite a nominee’s professional qualifications or
character as the key criterion,3 others may stress the importance of the nominee’s judicial

of a Nom inee, by Barry J. McMillion, and CRS Report R44236, Suprem e Court Appointment Process: Consideration
by the Senate Judiciary Com m ittee, by Barry J. McMillion.
2 “T he advice-and-consent role of the Senate,” one of its Members noted in 1994, “is something that we do not take
lightly because this is the only opportunity for t he people of this Nation to express whether or not they deem a nominee
qualified to sit on the highest court in the land.” Sen. Mark O. Hatfield, “Nomination of Stephen G. Breyer, of
Massachusetts, T o Be an Associate Justice of the Supreme Court of the United States,” remarks in the Senate,
Congressional Record, July 29, 1994, pp. S18692-18693.
3 For example, during 1991 Senate debate on the Supreme Court nomination of Judge Clarence T homas, the criterion of
professional qualification was cited by both supporters and opponents of the nominee to explain their votes. A Senator
supporting the T homas nomination maintained that instead of the nominee’s “philosophy on particular issues” which
might come before the Supreme Court, the “more appropriate standard” was that the nominee “have outstanding legal
ability and wide experience and meet the highest standards of integrity, judicial temperament, and professional
competence.” Judge T homas, the Senator added, “clearly meets that standard.” Sen. Frank H. Murkowski, “Nomination
of Clarence T homas to the Supreme Court,” remarks in the Senate, Congressional Record, October 1, 1991, p. S24748.
Other Senators, however, used the criterion of professional competence to find Judge T homas unqualified. One, for
example, found the nominee’s “ legal background and experience” inadequate and added that, if a President did not
nominate to the court “well-qualified, experienced individuals, the American people have the right to expect that the
members of the Senate will reject the nomination.” Sen. Jeff Bingaman, “ Justice Clarence T homas,” remarks in the
Senate, Congressional Record, October 2, 1991, p. S24973.

philosophy or views on constitutional issues,4 while stil others may indicate that they are
influenced in varying degrees by al of these criteria.5
Professional Qualifications
Just as most Presidents want their Supreme Court nominees to have unquestionably outstanding
legal qualifications, most Senators also look for a high degree of merit in nominees to the Court.
Consequently, floor remarks by Senators often focus, in part, on the professional qualifications of
a nominee—both in recognition of the demanding nature of the work that awaits an appointee to
the Court, but also because of the public’s expectations that a Supreme Court nominee be highly
qualified.6
With such expectations of excel ence, floor remarks by Senators often highlight the various ways
in which nominees have distinguished themselves in the law (as lower court judges, legal
scholars, or attorneys in private practice), or in other types of professional positions (such as
elective office).7 Given the importance of a nominee’s professional qualifications in the selection
and confirmation process, Senators have on occasion questioned—either directly or indirectly in

4 During debate over the nomination of Clarence T homas in 1991, these criteria were used both by Senators favoring
the nomination and by others opposing it. One Senator in support of the nomination, for example, declared his desire to
have “Supreme Court Justices who will interpret the Constitution and not attempt to legislate or carry out personal
agendas from the bench.” Sen. Richard C. Shelby, “Nomination of Judge Clarence T homas T o Be an Associate Justice
of the U.S. Supreme Court,” remarks in the Senate, Congressional Record, October 1, 1991, p. S24703. By contrast,
another Senator, explaining his opposition to confirming Judge T homas, said that if Senators were “ not confident that
nominees possess a clear commitment to the fundamental constitutional rights and freedoms at the heart of our
democracy, they should not be confirmed.” Sen. Edward M. Kennedy, “Nomination of Claren ce T homas, of Georgia,
T o Be an Associate Justice of the Supreme Court of the United States,” remarks in the Senate, Congressional Record,
October 3, 1991, p. S25271.
5 “In addition to the obvious criteria any nominee for the Supreme Court ought to have—I suppose any nominee for any
position on the judiciary ought to have—those of intellect, of integrity, and of judicial temperament, it is very
appropriate of the Senate t o inquire into a nominee’s judicial philosophy. Of course, that includes the nominee’s
fidelity to the Constitution. It involves that nominee’s understanding of the limited role of the courts, and it involves
what I hope is a commitment to judicial restraint.” Sen. Charles E. Grassley, “ Supreme Court of the United States,”
remarks in the Senate, Congressional Record, August 2, 1993, p. S18133. Similarly evincing concern with both a
nominee’s professional qualification and his constitutional values was this 1991 Senate floor statement during debate
on the nomination of Clarence T homas: “When I face a Supreme Court nominee I have three questions: Is he or she
competent? Does she or he possess the highest personal and professional integrity? And, third, will he or she protect
and defend the core constitutional values and guarantees around free of speech, religion, equal protection of the law,
and the right of privacy?” Sen. Barbara A. Mikulski, “Nomination of Clarence T homas, of Georgia, T o Be An
Associate Justice of the Supreme Court of the United States,” remarks in the Senate, Congressional Record, October
15, 1991, p. S26299. More recently, Senator Chuck Schumer stated, “ I have always had a consistent standard for
evaluating judicial nominees. I use it when voting for them. I use it when joining in, in the nomination process. I did
under President Bush and continue to under President Obama. T hose three standards are excellence, moderation, and
diversity.” Sen. Chuck Schumer, “Sotomayor Nomination,” remarks in the Senate, Congressional Record, June 23,
2009, p. S6914.
6 Senator Mitch McConnell, for example, has stated “T he American people also want a nominee with the requisite legal
experience. T hey instinctively know a lifetime position on the Supreme Court doe s not lend itself to on-the-job
training.” Sen. Mitch McConnell, “Nomination of Elena Kagan,” remarks in the Senate, Congressional Record, May
10, 2010, p. S3453.

Patrick Leahy, “Kagan Nomination,” remarks in the Senate, Congressional Record, June 7, 2010, p. S4610; Sen. Dick
Durbin, “Sotomayor Nomination,” remarks in the Senate, Congressional Record, July 7, 2009, p. S7155; Sen. Bill

their floor remarks—whether a nominee has the requisite professional qualifications or
experience to be appointed to the Court.8
Judicial Philosophy or Ideology
In recent decades, Senate debate on virtual y every Supreme Court nomination has focused to
some extent on the nominee’s judicial philosophy, ideology, constitutional values, or known
positions on specific legal controversies. Many highly controversial decisions of the Court in
recent decades have been closely decided, by 5-4 votes, appearing to underscore a long-standing
philosophical or ideological divide in the Court between its more so-cal ed liberal and so-cal ed
conservative members. A new appointee to the Court, Senators recognize, could have a
potential y decisive impact on the Court’s currently perceived ideological “balance” and on
whether past rulings of the Court wil be upheld, modified, or overturned in the future.9
Announcements by the Court of 5-4 decisions, a journalist covering the Court in 2001 wrote, had
“become routine, a familiar reminder of how much the next appointment to the court wil
matter.”10
Senators sometimes wil indicate in their floor statements whether they believe the views of a
particular nominee, although not in complete accord with their own views, nonetheless, fal

8 T his issue arose, for example, during Elena Kagan’s nomination to the Supreme Court (Ms. Kagan was the first
appointee to the Court since 1981, when Sandra Day O’Connor was appointed, who was not serving as a U.S. circuit
court judge at the time of being nominated).
In floor remarks about Kagan’s nomination, Senator Mitch McConnell stated that “ one does not need to have prior
experience as a judge before being appointed to the country’s highest Court, but it strikes me that if a nominee does not
have traditional experience, t hey should have substantial litigation experience. Ms. Kagan has neither, unlike Justice
Rehnquist, for instance, who was in private practice for 16 years prior to his appointment as Assistant Attorney General
for the Office of Legal Counsel, a job he had at the time of his appointment to the Supreme Court.” Sen. Mitch
McConnell, “Nomination of Elena Kagan,” remarks in the Senate, Congressional Record, May 10, 2010, p. S3453. In
contrast, another Senator argued that Kagan, as a result of “more than 24 years of legal experience in a range of
settings, she will bring a distinct perspective to judging that will serve both the Court and Americans well.” Sen. Jeanne
Shaheen, “Nomination of Elena Kagan,” remarks in the Senate, Congressional Record, June 16, 2010, p. S4956.
9 T hree political scientists, for example, wrote in 2002 that although “speculation about possible Supreme Court
vacancies is usually met with much interest by court watchers, it is particularly intense at present due to the ideological
balance of the current Court and the recent politics of the judicial confirmation process. Given the delicate ideological
balance on the current Court, a single vacancy could produce a dramatic shift in the ideological direction of future
rulings.” Kenneth L. Manning, Bruce A. Carroll, and Robert A. Carp, “George W. Bush’s Potential Supreme Court
Nominees: What Impact Might T hey Have?” Judicature, vol. 85, May-June 2002, p. 278.
10 Linda Greenhouse, “Divided T hey Stand: T he High Court and the T riumph of Discord,” The New York Times,
July 15, 2001, sec. 4, p. 1. Following the next two appointments to the Court —of Chief Justice John G. Roberts Jr. in
2005 and Associate Justice Samuel A. Alito Jr. in 2006 —the proportion of 5-4 rulings by the Court increased. At the
end of the Court’s October 2006 term (the first full term with both Justices Roberts and Alito on the Court),
Greenhouse reported that “[f]ully a third of the court’s decisions, more than in any recent term, were decided by 5 -to-4
margins. Most of those, 19 of 24, were decided along ideological lines, demonstrating the court’s polarization whether
on constitutional fundamentals or obscure questions of appellate procedure.” Greenhouse added, “Of the ideological
cases decided this term, the conservative majority, led by Chief Justice John G. Roberts Jr. and joined by Justices
Antonin Scalia, Clarence T homas and Samuel A. Alito Jr., prevailed in 13. T he court’s increasingly marginalized
liberals—Justices John Paul Stevens, David H. Souter, Ruth Bader Ginsburg and St ephen G. Breyer—prevailed in
only six.... ” Linda Greenhouse, “ In Steps Big and Small, Supreme Court Moved Right,” The New York Tim es, July 1,
2007, p. 1. For the 2014-2015 term, 19 (or 26%) of the Court’s opinions were 5 -4 rulings (13 of the 19 cases, or 68%,
were decided along ideological lines—with Justices Roberts, Scalia, Kennedy, T homas, and Alito voting opposite
Justices Breyer, Ginsburg, Sotomayor, and Kagan). While the percentage of all opinions that were 5 -4 rulings for the
2014-2015 term was the fourth highest of the 10 terms since 2005 -2006, the percentage of 5-4 rulings that were decided
along ideological lines was sixth highest during these sam e 10 terms. Data available online at

within a broad range of acceptable legal thinking.11 Senators’ concerns with a nominee’s judicial
philosophy or ideology may become heightened, and their positions more polarized relative to
other Senators’, if a nominee’s philosophical orientation is seen as controversial, or if the
President is perceived to have made the nomination with the specific intention of changing the
Court’s ideological balance.12

11 For example, during 1994 floor debate on the Supreme Court nomination of Stephen G. Breyer, one Senat or said of
the nominee’s views, “Certainly in terms of an expansive definition of the Constitution, I have no doubt that Judge
Breyer is going to make rulings that represent a different interpretation of the great document than I have and that
people who share my views have. But I also believe that Judge Breyer’s views are mainstream liberal views. I believe
that anyone who voted for Bill Clinton knew or should h ave known that the chances [of] anyone more conservative
than Judge Breyer being nominated by Bill Clinton were almost zero.” Sen. Phil Gramm, “Nomination of Stephen G.
Breyer, of Massachusetts, T o Be an Associate Justice of the Supreme Court of the United States,” remarks in the
Senate, Congressional Record, July 29, 1994, pp. S18671-18672.
12 Most recently, the nomination of Brett Kavanaugh to replace Justice Kennedy was considered controversial by some
Senators because of the possibility that Judge Kavanaugh’s appointment to the Court would shift the Court’s
ideological balance in a more conservative direction on one or more issues. See, for example, floor statements by Sen.
Elizabeth Warren, “Nomination of Brett Kavanaugh,” remarks in the Senate, Congressional Record, August 1, 2018,
pp. S5555-5556; by Sen. Patty Murray, “ Executive Session,” remarks in the Senate, Congressional Record, July 18,
2018, pp. S5032-5033; and by Sen. Ed Markey, “ Executive Session,” remarks in the Senate, Congressional Record,
July 12, 2018, p. S4930-4931.
Prior to the vacancy created by the retirement of Justice Kennedy, one reason for Senate division over the nomination
of Samuel A. Alito Jr. in 2005-2006 was a widespread perception that confirmation of Alito would change the
ideological balance of the Court (specifically, he might align in decisions with Justices whose views were regarded by
some as conservative). Alito was nominated to replace Sandra Day O’Connor, perceived by many as a moderate or
“swing” vote on the Court. See, for example, Seth Stern and Keith Perine, “Alito Confirmed After Filibuster Fails,” CQ
Weekly, vol. 64, February 6, 2006, p. 340 (characterizing Alito’s confirmation, “ by a mostly party-line vote of 58-42,”
as “the culmination of years of planning by conservatives to move the court to t he right”); also, “A Supreme
Nomination,” The Washington Times, November 1, 2005, p. A18 (editorial describing the nomination as “the moment
conservatives have been waiting for” and predicting a “confirmation battle” in the Senate).
Earlier, in 1987, Senat e concern with a nominee’s judicial philosophy was also especially heightened when President
Reagan nominated appellate court judge Robert H. Bork to the Court. T he nomination sparked immediate controversy,
and polarized the Senate generally along party lines, in large part because of the nominee’s judicial philosophy of
“original intent” and the perception that he had been nominated by President Reagan to move the Court in the future in
what was characterized as a more conservative direction. For analysis of how central an issue Judge Bork’s judicial
philosophy was in the Senate confirmation battle, see John Massaro, Suprem ely Political: The Role of Ideology and
Presidential Managem ent in Unsuccessful Suprem e Court Nom inations. (Albany, NY: State University of New York
Press, 1990), pp. 159-193. (Hereafter cited as Massaro, Suprem ely Political.)
In a Senate floor statement shortly after the Bork nomination was made, the then -chair of the Senate Judiciary
Committee, Sen. Joseph R. Biden, Jr. (D-DE), faulted t he President for his choice. Senator Biden declared that when a
President selects nominees “with more attention to their judicial philosophy and less attention to their detachment and
statesmanship,” a Senator “has not only the right but the duty to respon d by carefully weighing the nominee’s judicial
philosophy and the consequences for the country.” T he Senate, he continued, had both the right and the duty to raise
political and judicial “questions of substance,” for “we are once again confronted with a po pular President’s determined
attempt to bend the Supreme Court to his political ends.” Sen. Joseph R. Biden Jr., “Advice and Consent: T he Right
and Duty of the Senate T o Protect the Integrity of the Supreme Court,” remarks in the Senate,” Congressional Record,
July 23, 1987, p. S20913 (first quote) and p. S20915 (second quote).
Various Senators who favored Judge Bork’s confirmation, however, disagreed with Senator Biden regarding the
importance of the nominee’s judicial philosophy. Some expressed a preference for a narrower scope of Senate inquiry,
focusing on Judge Bork’s legal competence and character. Others considered Judge Bork’s judicial philosophy and
views of the Constitution appropriate areas of inquiry, but the crucial determination for the Senate to make in these
areas, they argued, was whether his views fell within a broad range of acceptable th inking, not whether individual
Senators agreed with those views. Further, some Senators maintained, to evaluate a nominee according to political or
judicial philosophy, or to vote to confirm only if Senators agreed with the nominee’s views, would politicize the
Supreme Court and undermine its independence of the legislative branch. See, for example, statements by Sen. Robert
Dole, “ T he Nomination of Robert Bork,” remarks in the Senate, Congressional Record, July 23, 1987, p. S10538.

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

During the George W. Bush presidency, a Senate Judiciary subcommittee examined the question
of what role ideology should play in the selection and confirmation of federal judges.13 In his
opening remarks, the chair of the subcommittee, Senator Charles E. Schumer (D-NY), stated that
it was clear that “the ideology of particular nominees often plays a significant role in the
confirmation process.” The current era, he said, “certainly justifies Senate opposition to judicial
nominees whose views fal outside the mainstream and who have been selected in an attempt to
further tilt the courts in an ideological direction.”14
By contrast, Senator Orrin G. Hatch (R-UT), in testimony before the subcommittee, declared that
there “are myriad reasons why political ideology has not been—and is not—an appropriate
measure of judicial qualifications. Fundamental y,” he continued, “the Senate’s responsibility to
provide advice and consent does not include an ideological litmus test because a nominee’s
personal opinions are largely irrelevant so long as the nominee can set those opinions aside and
follow the law fairly and impartial y as a judge.”15
More recently, Senators of both parties have based, at least in part, their opposition to particular
Supreme Court nominations on the belief that a nominee’s ideological disposition or views on
specific issues fal outside the mainstream of legal thought or public opinion.16
Views of Peers, Constituents, Interest Groups, and Others
Other factors also may figure importantly into a Senator’s confirmation decisions. One, it has
been suggested, is peer influence in the Senate (especial y, perhaps, when the nomination is
viewed as controversial).17 Particularly influential, for instance, might be Senate colleagues who
are championing a nominee or spearheading the opposition,18 or who played prominent roles in
the Judiciary Committee hearings stage. Another consideration for Senators wil be the views of
their constituents, especial y if many voters back home are thought to feel strongly about a
nomination.19 Other influences may be the views of a Senator’s advisers, family, and friends, as

related issue involving judicial nominations—namely, does the “ burden of proof” lie with the nominee, to demonstrate
that he or she merits appointment to the federal bench, or with Senate opponents, to demonstrate that the nominee is
unfit for confirmation? T he hearing, entitled “The Senate’s Role in the Nomination and Conf irmation Process: Whose
Burden?” featured two panels of witnesses, some arguing for, and others against , placing the burden of proof on the
nominee. Ibid., pp. 111-218 (for the complete record of the hearing on September 4).

17 See Watson and Stookey, Shaping America, pp. 191-195, for discussion of how a relatively few number of Senators
may serve as “ cues” to other Senators during the consideration of controversial Supreme Court nominations.
18 See, for example, Seth Stern, “‘Bork’s America’ Resounds,” CQ Weekly, vol. 67, September 7, 2009, p. 1987, where

galvanizing Senate opposition to the Bork nomination.

wel as the position taken on the nomination by advocacy groups that the Senator ordinarily trusts
or looks to for perspective.20
Diversity Considerations
Just as Presidents are assumed to do when considering prospective nominees for the Supreme
Court, Senators may evaluate the suitability of a Supreme Court nominee according to whether
certain groups, constituencies, or individuals with certain characteristics are adequately
represented on the Court.21 Among the representational criteria commonly considered have been
the nominee’s party affiliation, geographic origin, ethnicity, religion, and gender.22
Senate Institutional Factors or Prerogatives
When considering Supreme Court nominations, Senators may also take Senate institutional
factors into account. For instance, the role, if any, that Senators from the home state of a nominee
played in the nominee’s selection, as wel as their support for or opposition to the nominee, may
be of interest to other Senators. At the same time, Senators may be interested in the extent to
which the President, prior to selecting the nominee, sought advice from other quarters in the
Senate—for instance, from Senate party leaders and from the chair, ranking minority member,
and other Senators on the Judiciary Committee. A President’s prior consultation with a wide
range of Senators concerning a nominee may be a positive factor for other Members of the
Senate, by virtue of conveying presidential respect for the role of Senate advice, as wel as Senate
consent, in the judicial appointments process.23

majority that they favor the confirmation of Judge T homas by this body.” Sen. Frank H. Murkowski, “ Nomination of
Clarence T homas, of Georgia, T o Be An Associate Justice of the Supreme Court of the United States,” remarks in the
Senate, Congressional Record, October 15, 1991, p. S26300.
20 See Watson and Stookey, Shaping America, pp. 198-199.
21 In recent decades, for instance, Presidents and Senators at various times have endo rsed the goal of increasing the
demographic diversity of the lower courts, as well as on the Supreme Court, to make the judiciary more representative
of the nation’s population.
22 Concern for adequate representation of women on the Court, for example, was expressed by some Senators after
President George W. Bush nominated Samuel A. Alito Jr. to succeed retiring Justice Sandra Day O’Connor. (President
Bush had nominated Alito after withdrawing his earlier nomination of White House counsel Harriet E. Miers to
succeed Justice O’Connor.) Confirmation of Alito, it was widely noted, would leave the Court with only one woman
member, Justice Ruth Bader Ginsburg. In this context, Sen. Barbara A. Mikulski (D-MD), during January 25, 2006,
floor debate on the Alito nomination, remarked, “After Harriet Miers was withdrawn, who did they give us? Certainly,
I think in all of the United States of America there was a qualified woman who could have been nominated to serve on
the Court.” Sen. Barbara A. Mikulski, “Nomination of Samuel A. Alito Jr. T o Be an Associate Justice on the Supreme
Court of the United States,” remarks in the Senate, Congressional Record, daily edition, January 25, 2006, p. S66.
More recently, after President Obama nominated Sonia Sotomayor to the Court, Senator Specter (D -PA) stated “ to talk
about being a Latino, well, what is wrong with a little ethnic pride? And isn’t it abo ut time we had some greater
diversity on the Supreme Court? Isn’t it surprising, if not scandalous, that it took until 1967 to have an African
American on the Court, T hurgood Marshall, and it took until 1981 to have the first woman on the Court, Sandra Day
O’Connor?” Sen. Specter, remarks in the Senate, Congressional Record, daily edition, August 5, 2009, p. S8800.
23 President George W. Bush, for instance, received bipartisan praise for personally, and through his aides, consulting
widely with Members of t he Senate, over a several week period, prior to nominating John G. Roberts Jr. to the Court in
2005. See, for example, the remarks of Majority Leader Bill Frist (R-T N), in “ Supreme Court Confirmation Process,”
remarks in the Senate, Congressional Record, daily edition, July 12, 2005, pp. S8091-S8092, and of Senate Democratic
Leader Harry Reid (D-NV) in “ Pressing Issues,” remarks in the Senate, Congressional Record, daily edition, July 11,
2005, pp. S7945-S7946. By contrast, President Bush’s announcement of Samuel A. Alito Jr. on October 31, 2005, as a
Court nominee, occurring four days after the withdrawal of a previous nominee to the same position (Harriet E. Miers),

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

Sometimes, Senators may find themselves debating whether the Senate, in its “advice and
consent” role, should defer to the President and give a nominee the “benefit of the doubt.” This
issue received particular attention during Senate consideration of the Supreme Court nomination
of Clarence Thomas in 1991. In that debate, some Thomas supporters argued that the Senate, as a
rule, should defer to the President’s judgment concerning a nominee except when unfavorable
information is presented overcoming the presumption in the nominee’s favor.24 Opponents, by
contrast, rejected the notion that there was a presumption in favor of a Supreme Court nominee at
the start of the confirmation process or that the President, in his selection of a nominee, is owed
any special deference.25
Floor Procedures for Considering the Nomination
After the Judiciary Committee has reported a nomination, it is placed on the Executive Calendar
and assigned a calendar number by the executive clerk of the Senate.26 As with other nominations
listed in the Executive Calendar, information about a Supreme Court nomination includes the
name and office of the nominee; the name of the previous holder of the office; whether the
committee reported the nomination favorably, unfavorably, or without recommendation; and, if
there is a printed report, the report number.
Business on the Executive Calendar, which consists of treaties and nominations, is considered in
executive session.27 Unless voted otherwise by the Senate, executive sessions are open to the
public.28 Floor debate on a Supreme Court nomination, in contemporary practice, invariably has

invitation to the White House, Senator Reid stated, “I received nothing more than a pro forma telephone call from the
President’s Chief of Staff, telling me he had selected Judge Alito about an hour before he announced the nominatio n.”
Sen. Harry Reid, “T he Nomination of Judge Alito,” remarks in the Senate,” Congressional Record, daily edition,
November 16, 2005, p. S12874.
24 Among those Senators supporting the nomination, one declared that he strongly believed “that a nominee comes to
the Senate with a presumption in his favor. Accordingly, opponents of the nominee must make the case against him,
especially since Judge T homas has been confirmed to positions of great trust and responsibility on four separate
occasions.” Sen. Strom T hurmond (R-SC), “Supreme Court of the United States,” remarks in the Senate, Congressional
Record, October 3, 1991, p. 25257. Another Senator stated that while his vote in favor of Judge T homas was not “ cast
without some doubt, ... I have tried to insist on every judicial nomination of every President that I would give both the
President and the nominee the benefit of the doubt.” Sen. Wyche Fowler Jr. (D-GA), “Supreme Court of the United
States,” remarks in the Senate, Congressional Record, October 3, 1991, p. 25270.
25 During the T homas nomination debate, for example, one Senator declared that “[i]n the selection of a person to serve
on the Nation’s highest court, in my view, the Senate is an equal partner with the President. T he President is owed no
special deference, and his nominee owed no special presumptions. We owe the public our careful and thorough
consideration and our independent judgment.” Sen. Frank R. Lautenberg (D-NJ), “Against the Confirmation of
Clarence T homas,” remarks in the Senate, Congressional Record, vol., 137, September 27, 1991, p. 24449. Likewise,
another Senator maintained that, on “a question of such vast and lasting significance, where the course of our future for
years to come is riding on our decision, the Senate should give the benefit of the doubt to the Supreme Court and to the
Constitution, not to Judge Clarence T homas.” Sen. Edward M. Kennedy (D-MA), “Nomination of Clarence T homas, of
Georgia, T o Be an Associate Justice of the Supreme Court of the United States,” remar ks in the Senate, Congressional
Record, October 15, 1991, p. 26290.

unanimous consent, a nomination on the Calendar cannot be taken up until it has been on the Calendar at least one day

Bringing the Nomination to the Floor30
The Senate’s executive business is comprised of nominations and treaties. The Senate considers
such business in executive session. Since the Senate typical y begins its day in legislative session
on any day it sits, the decision to proceed to executive session and consider a specific nomination
is made while the Senate is in legislative session.31
Consideration of a nomination is scheduled by the majority leader, who typical y consults with
the minority leader and al interested Senators.32 In previous Congresses, the typical practice in
cal ing up a Supreme Court nomination was for the majority leader to consult with the minority
leader and interested Senators and to ask for unanimous consent that the Senate proceed to
executive session and consider the nomination. The leader asked for unanimous consent to
proceed to executive session to consider the nomination immediately,33 or at some specified time
in the future.34

Associate Justice—in open session, waiving a rule requiring the chamber to consider nomination s in closed session. In
1929, the Senate amended its rules to provide for debate on nominations in open session unless there were a vote to go
into closed session. T henceforth, it became the regular Senate practice to conduct debate on nominations, includi ng
those to the Supreme Court, in open session.
29 T he Senate has allowed gavel-to-gavel broadcast coverage of Senate floor debate since June 1986. T he Senate’s first
floor debates on Supreme Court nominations ever to be televised were its September 1986 de bates on the nominations
of William H. Rehnquist to be Chief Justice and Antonin Scalia to be an Associate Justice.

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

A unanimous consent request also could include a limit on the time that wil be al owed for
debate and specify the date and time on which the Senate wil vote on a nomination.35 Typical y,
the amount of time agreed upon for debate is divided evenly between the majority and minority
parties, who usual y have as their respective floor managers the chair and ranking minority
member of the Judiciary Committee. If agreed to, a time limit on debate, with a date and time set
for a final Senate vote on the nomination, precludes unlimited debate or delay in considering a
nomination and the possibility of a filibuster. Conversely, if the Senate agrees by unanimous
consent to consider a nomination, but does not provide for a time limit on debate or specify when,
or under what circumstances, a Senate vote wil take place, extended debate is possible, although
not necessarily inevitable.36
When unanimous consent to cal up a nomination has not been secured, the majority leader may
make a motion that the Senate proceed to consider the nomination. As already explained, such a
motion is made while the Senate is in legislative session.37 The motion is not debatable. Since

at 9:30 a.m., August 3, the Senate, immediately after its opening, proceed to consider the Supreme Court nomination of
Elena Kagan. Sen. Christopher J. Dodd, “Unanimous Consent Agreement—Executive Calendar,” Congressional
Record, daily edition, August 2, 2010, p. S6593.
35 In this vein, Majority Leader George J. Mitchell (D-ME), on July 28, 1994, while the Senate was in legislative
session, asked unanimous consent that at 9 a.m. on July 29, the Senate proceed to executive session to consider the
Supreme Court nomination of Stephen G. Breyer. T he unanimous consent request also specified that there be six hours
of debate, after which the Senate, “without any intervening action on t he nomination,” would vote on whether to
confirm. Sen. George J. Mitchell, “Unanimous-Consent Agreement,” remarks in the Senate, Congressional Record,
July 28, 1994, p. 18544. Likewise, unanimous consent requests limited the time for debate and set the dat e and time for
Senate votes on the Supreme Court nominations of Ruth Bader Ginsburg (1993), Clarence T homas (1991), Anthony M.
Kennedy (1988), and Sandra Day O’Connor (1981).
36 For example, a September 27, 1990, unanimous consent agreement, which provided for the Senate to proceed to the
Supreme Court nomination of David H. Souter at 2:30 p.m ., October 2, did not also provide for a time limit on the
debate, or for a vote at the end of that debate. Despite the absence of these provisions in the unanimous con sent
agreement, the Senate concluded its debate and voted to confirm, on the same day (October 2) that it began debate on
the Souter nomination. Likewise, the Senate on August 29, 1967, by unanimous consent, proceeded to consider the
Supreme Court nomination of T hurgood Marshall, without also providing for a time limit on the debate, or for a
scheduled time for a vote on confirmation. “Supreme Court of the United States,” Congressional Record, August 29,
1967, p. 24437. Even in the absence of such provisions, the Senate concluded debate on, and voted to confirm, the
Marshall nomination the next day, August 30.
Also, the Senate, without providing for a vote on confirmation, may enter into one or more unanimous consent
agreements, each with a time limit, to complete debate time and ultimately arrive at a time for a vote on confirmation.
T hat was the scenario followed when, in 2005, the Senate considered the nomination of John G. Roberts Jr. to be Chief
Justice. Initial consideration of the Roberts nomination, o n September 26, 2005, occurred pursuant to a unanimous
consent agreement entered into on September 22, 2005. T he agreement specified the precise amounts of time on
September 26 to be allotted to the majority and minority party leaders or their designees fo r debate on the nomination,
without, however, setting a date and time for a vote on confirmation. “Orders for Monday, September 26, 2005,”
Congressional Record, daily edition, September 22, 2005, p. S10392. Pursuant to three additional unanimous consent
(UC) agreements, further Senate consideration of the nomination followed, on September 27, 28, and 29, 2005,
culminating in a 78-22 vote to confirm on September 29. (A complete chronology of Senate actions on the Roberts
nomination, including all unanimous consent agreements reached on the nomination, can be accessed using the
nominations database of the Legislative Information System [LIS] of the U.S. Congress.)
37 If the majority leader moves to consider the nomination during executive session (rather than when the Senate is in
legislative session), the motion is debatable under Senate rules. Closing debate on the motion, in turn, may require the
Senate to invoke cloture by an affirmative vote of three-fifths of the entire Senate membership (60 Senators if there are
no vacancies). Note that a majority leader today is unlikely to make such a motion while in executive session since the

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

1980, the Senate has explicitly established the precedent that a nondebatable motion may be made
to go into executive session to take up a specified nomination.38 One congressional scholar
observed that the precedent limits a potential filibuster to the nomination itself.39
Filibusters and Motions to End Debate
Senate rules place no limits on how long floor consideration of a nomination may last.40 With
time limits lacking, Senators opposing a Supreme Court nominee may seek, if they are so
inclined, to use extended debate or delaying actions to postpone or prevent a final vote from
occurring. The use of dilatory actions for such a purpose is known as a filibuster.41
By the same token, however, supporters of a Court nomination have available to them a
procedure for placing time limits on consideration of a matter—the motion to invoke cloture.42
When the Senate agrees to a cloture motion on a Supreme Court nomination, further
consideration of the matter being debated is limited to 30 hours. The majority required for cloture
on nominations, including Supreme Court nominations, is a majority of Senators voting, a
quorum being present. By invoking cloture, the Senate ensures that a nomination may ultimately
come to a vote and be decided by a voting majority.
The Senate reinterpreted its cloture rule to al ow a majority of Senators voting to invoke cloture
on a Supreme Court nomination on April 6, 2017.43 Shortly thereafter the Senate was able to
invoke cloture on the nomination of Neil M. Gorsuch to be a Supreme Court Justice by a vote of
55-45.44

motion is debatable.
T he debatable nature of a motion to consider, when made in executive session, was demonstrat ed in 1968, when the
nomination of Associate Justice Abe Fortas to be Chief Justice was brought to the Senate floor. T he episode marked the
most recent Senate proceedings in which a m otion was made to proceed to consider a Supreme Court nomination while
the Senate was in executive session. Significant opposition within the Senate to the Fortas nomination raised the
theoretical possibility of two filibusters being mounted—the first against the motion to consider, and then (if Fortas
supporters were successful in ending debate on the first filibuster) a second, against the nomination itself. T he vote on
the motion to close debate on the motion to consider the Fortas nomination was 45-43, well short of the supermajority
then required by Senate rules for passage of a “cloture motion” (prior to 1975, two -thirds of Senators present and
voting). Consequently, t he second filibuster did not materialize after the Senate failed to reach the supermajority
required to close debate on the motion to consider. Shortly after the unsuccessful attempt at cloture on the motion to
consider, the Fortas nomination was withdrawn by President Lyndon B. Johnson.

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

Prior to the 2017 precedent, a supermajority was required to invoke cloture on a Supreme Court
nomination. Motions to bring debate on Supreme Court nominations to a close under the previous
procedures were made on four prior occasions.45 The first use occurred in 1968, when Senate
supporters of Justice Abe Fortas tried unsuccessfully to end debate on the motion to proceed46 to
his nomination to be Chief Justice. After the motion was debated at length, the Senate failed to
invoke cloture by a 45-43 vote,47 prompting President Lyndon Johnson to withdraw the
nomination. The 45 votes in favor of cloture fel far short of the supermajority required—then
two-thirds of Senators present and voting, a quorum being present.
A cloture motion to end debate on a Court nomination occurred again in 1971, when the Senate
considered the nomination of Wil iam H. Rehnquist to be an Associate Justice. Although the
cloture motion failed by a 52-42 vote,48 Rehnquist was confirmed later the same day.49 In 1986, a
cloture motion was filed on a third Supreme Court nomination, this time of sitting Associate
Justice Rehnquist to be Chief Justice. Supporters of the nomination mustered more than the three-
fifths majority needed to end debate (with the Senate voting for cloture 68-31),50 and Justice
Rehnquist subsequently was confirmed as Chief Justice.
A cloture motion was presented to end consideration of a Supreme Court nomination a fourth
time, during Senate consideration of the nomination of Samuel A. Alito Jr. in January 2006. The
motion was presented on January 26, after two days of Senate floor debate on the nomination.51
On January 30, the Senate voted to invoke cloture by a 72-25 vote,52 and the next day it
confirmed the Alito nomination by a final vote of 58-42.53
As one news analysis at the time observed, Senators “are traditional y hesitant to filibuster”
Supreme Court nominations.54 Indicative of this, the article noted, was the fact that some of the
“most divisive Supreme Court nominees in recent decades, including Associate Justice Clarence
Thomas, have moved through the Senate without opponents resorting to that procedural

45 It has only been since 1949, under Senate rules, that cloture could be moved on nominations. Prior to 1949, dating
back to the Senate’s first adoption of a cloture rule in 1917, cloture motions could be filed only on legislat ive measures.

46 As mentioned above, prior to 1980, the motion to proceed to consider a specific nomination on the Executive
Calendar was debatable.

weapon.”55 In 1991, five days of debate on the Thomas nomination concluded with a 52-48
confirmation vote. The 48 opposition votes would have been more than enough to defeat a cloture
motion if one had been filed. In three earlier episodes, Senate opponents of Supreme Court
nominations appear to have refrained from use of the filibuster, even though their numbers would
have been sufficient to defeat a cloture motion. In 1969, 1970, and 1987 respectively, lengthy
debate occurred on the unsuccessful nominations of Clement F. Haynsworth, G. Harrold
Carswel , and Robert H. Bork. In none of these episodes, however, was a cloture motion filed,
and in each case debate ended with a Senate vote rejecting the nomination.
Final Vote on Whether to Confirm the Nomination
Number of Days from Nomination to Final Vote
Historical y, there has been variation in the length of time from a President nominating a person
for a vacancy on the Supreme Court to a final Senate vote on that person’s nomination. For
nominees since 1975 who have received a final floor vote, Figure 1 shows the number of
calendar days that elapsed from the date on which the nomination was formal y submitted to the
Senate to the date on which the Senate voted whether to approve the nomination.56
Of the 15 nominees listed in the figure, Robert Bork waited the greatest number of days (108)
from nomination to a final Senate vote—followed by Clarence Thomas (99), while John Paul
Stevens waited the fewest number of days (19)—followed by Sandra Day O’Connor (33).57
Overal , the average number of days from nomination to final Senate vote is 70.8 days (or
approximately 2.3 months), while the median is 71.0 days.58
Of the 8 Justices currently serving on the Court, the average number of days from nomination to
final Senate vote is 77.8 days (or approximately 2.6 months), while the median is 77.5 days.
Among the current Justices, John Roberts waited the fewest number of days from nomination to
confirmation (62), while Clarence Thomas waited the greatest number of days (99).

55 Ibid.
56 It is not uncommon for a President to announce his choice for a vacancy prior to formally submitting the nomination
to the Senate. For the purposes of Figure 1, the date on which the nomination is formally submitted (not the date on
which the President announces whom he intends to nominate) is used in the calculation. Using the date the nomination
is submitted provides a better measure of how long a nominee waits for a final vote once his or her nomination has
formally been submitted to the Senate for consideration.
57 For some nominees, the number of days from nomination to a final Senate vote increases as a result of a
congressional recess or break intervening between the date the nomination is submitted to the Senate and the date of the
Senate vote. For example, Samuel Alito was nominated on November 10, 2005. T he Senate was not in session during a
number of days in November and December of 2005 (as well as in January of 2006) —the days that the Senate was not
in session during this period likely increased the number of days from Alito’s nomination to the Senate’s final vote on
his nomination (which occurred on January 31, 2006).
58 T he average is calculated by adding a group of numbers and then dividing that value by how many numbers there
are, while the median is the middle value for a particular set of numbers (i.e., half of the numbers are above the median
and half are below it). Although the average is a more commonly used measure, the median is less affected by outliers
or extreme cases (e.g., nominees for whom the time from nomination to final vote was relatively much shorter or longer
than it was for other nominees). Consequently, the median might be a better measure of central tendency.

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

Type of Vote
When floor debate on a nomination comes to a close, the presiding officer puts the question of
confirmation to a vote. In doing so, the presiding officer typical y states, “The question is, Wil
the Senate advise and consent to the nomination of [nominee’s name] of [state of residence] to be
an Associate Justice [or Chief Justice] on the Supreme Court?”60
A roll-cal vote to confirm requires a simple majority of Senators present and voting, a quorum
being present.61 Since 1967, every Senate vote on whether to confirm a Supreme Court
nomination has been by roll cal .62 Prior to 1967, by contrast, fewer than half of al of Senate
votes on whether to confirm nominees to the Court were by roll cal , with the rest by voice vote.63
For roll-cal votes on Supreme Court nominations, the formal procedure by which Senators cast
their votes on the floor has varied over the years. In recent decades prior to 1991, it was the usual
practice for Senators, during the cal ing of the roll, to be free to come and go, and not have to be
present in the Senate chamber for the entire cal ing of the roll. However, for several recent
Supreme Court nominations to receive final Senate votes on confirmation the majority leader or
the presiding officer, immediately prior to the cal ing of the roll, has asked al of the Senate’s
Members to remain seated at their desks during the entire vote—with each Senator rising and
responding when his or her name is cal ed.64 Voting from the desk during roll cal s is in keeping
with a standing order of the Senate,65 which rarely, however, is actual y enforced;66 nevertheless,
the rule has been applied by Senate leaders, in recent years, to roll-cal votes on Supreme Court
nominations, to mark the special significance for the Senate of deciding whether to confirm an
appointment to the nation’s highest court.67

60 T he wording of the question is provided for by Rule XXXI, paragraph 1, Standing Rules of the Senate, at
http://www.rules.senate.gov/public/index.cfm?p=RuleXXXI, which provides t hat “ the final question on every
nomination shall be, ‘Will the Senate advise and consent to this nomination?”
61 See CRS Report RL31980, Senate Consideration of Presidential Nominations: Committee and Floor Procedure, by
Elizabeth Rybicki. T his quorum requirement is derived from Article I, Section 5, clause 1 of the Constitution, which
states in part that “a Majority of each [House] shall constitute a Quorum to do Business.... ” Hence, the quorum for
conducting business in a Senate of 100 Members is 51 Senators.
62 Of the 23 nominations since 1967, 5 received 0 nay votes (Kennedy, Scalia, O’Connor, Stevens, Blackmun), 3
received fewer than 5 nay votes (Ginsburg, Powell, Burger), 3 received between 6 and 11 nay votes (Breyer, Souter,
Marshall), 9 received between 20 and 49 nay votes (Kavanaugh, Gorsuch, Kagan, Sotomayor, Roberts, Alito, T homas,
and both of Rehnquist’s nominations), and 3 received more than 50 nays (Bork, Carswell, Haynsworth).
63 T he most recent voice votes by the Senate on Supreme Court nominations were those confirming Abe Fortas in 1965
(to be an Associate Justice) and Arthur J. Goldberg and Byron R. White, both in 1962. Of the 137 Senate votes cast in
all, from 1789 to 2018, on whether to confirm a Supreme Court nominee, 64 were done by roll-call votes, and the other
73 by voice votes or unanimous consent.
64 For example, during the confirmation votes on the nominations of Sonia Sotomayor and Elena Kagan, Senators
remained at their desks during the calling of the roll.
65 S.Res. 480, approved by the Senate on October 11, 1984, provided: “Resolved, T hat it is a standing order of the
Senate that during yea and nay votes in the Senate, each Senator shall vote from the assigned desk of the Sen ator.” See
U.S. Congress, Senate, Senate Manual Containing the Standing Rules, Orders, Laws , and Resolutions Affecting the
Business of the United States Senate, S. Doc. 107-1, 107th Cong., 1st sess. (Washington: GPO. 2002), p. 151.
66 “Senators are required to vote from their desks, but this requirement rarely is enforced. On occasion, when a vote of
special constitutional importance, such as a vote to convict in an impeachment trial, is about to begin, the majority
leader will ask all Senators to come to t he floor before the vote begins and t hen to vote from their desks, each Senator
rising and responding when his or her name is called.” CRS Report 96-452, Voting and Quorum Procedures in the
Senate, coordinated by Elizabeth Rybicki, p. 7.
67 Immediately prior to the Senate’s roll-call vote in 1994 on whether to confirm Stephen G. Breyer to be an Associate
Justice, Majority Leader George J. Mitchell (D-ME) stated to his colleagues on the floor that “ it has been the practice

Vote Outcome and Number of Nay Votes
Historical y, vote margins on Supreme Court nominations have varied considerably. Most votes
have been overwhelmingly in favor of confirmation.68 Some recorded votes, however, either
confirming or rejecting a nomination, have been close.69
For nominations receiving a final floor vote since 1975, Figure 3 shows whether the nomination
was confirmed by the Senate or not confirmed. For nominations approved, the level of support
among Senators voting on the nomination is indicated as follows: (1) unanimous support (i.e., no
nay votes cast on the nomination); (2) some opposition (fewer than 10 nay votes cast on the
nomination); (3) some opposition (more than 10 nay votes cast on the nomination, but at least
half of the Senators not belonging to the President’s party stil voted aye on the nomination); and
(4) party opposition (a majority of Senators not belonging to the President’s party cast nay votes
on the nomination). The number of dots at the top of each column indicates the number of
nominees in each category.
Of the 16 nominations receiving a final floor vote, 15 were confirmed. Of the 15 nominations
approved by the Senate, 7 were approved despite receiving nay votes from a majority of Senators
not belonging to the President’s party.70 These seven include the five most recent nominations to
the Court, those of Brett Kavanaugh (2018), Neil Gorsuch (2017), Elena Kagan (2010), Sonia
Sotomayor (2009), and Samuel Alito (2006). Additional y, a majority of Senators not belonging to
the President party’s voted against the Clarence Thomas nomination (1991), as wel as the
nomination of Wil iam Rehnquist to be Chief Justice (1986).
In only one of the seven cases identified above did the President’s party not also hold a majority
of seats in the Senate. Specifical y, in 1991, President George H. W. Bush (a Republican)
nominated Thomas—who was opposed by a majority of Democratic Senators (and whose party

that votes on Supreme Court nominations are made from the Senator’s desk. I ask that Senators cast their votes from
their desks during this vote.” Congressional Record, July 29, 1994, p. 18704. Again, in 2006, moments before the
Senate’s vote on nominee Samuel A. Alito Jr., t he importance of a Supreme Court nomination was cited by the
Senate’s majority leader in applying the Senate rule that Members vote from their desks on a roll-call votes: “So,
momentarily, we will vote from our desks, a time-honored tradition that demonstrates, once again, how important and
consequential every Member takes his duty under the Constitution to provide advice and consent on a Supreme Court
nomination and to give the nominee the fair up -or-down vote he deserves.” Sen. Bill Frist, “ Nomination of Judge
Samuel Alito to the U.S. Supreme Court,” remarks in the Senate, Congressional Record, daily edition, January 31,
2006, p. 348.
68 T he most lopsided of these votes were the unanimous roll calls confirming Morrison R. Waite to be Chief Justice in
1874 (63-0), Harry A. Blackmun in 1970 (94-0), John Paul Stevens in 1975 (98-0), Sandra Day O’Connor in 1981
(99-0), Antonin Scalia in 1986 (98-0), and Anthony M. Kennedy in 1988 (97 -0); and the near-unanimous votes
confirming Noah H. Swayne in 1862 (38 -1), Warren E. Burger in 1969 to be Chief Justice (74-3), Lewis F. Powell Jr.
in 1971 (89-1), and Ruth Bader Ginsburg in 1993 (96-3).
69 T he closest roll calls ever cast on Supreme Court nominations were the 24 -23 vote in 1881 confirming Stanley
Matthews, the 25-26 vote in 1861 rejecting a motion to proceed to consider the nomination of Jeremiah S. Black, and
the 26-25 Senate vote in 1853 to postpone consideration of the nomination of George E. Badger. Since the 1960s, the
closest roll calls on Supreme Court nominations were the 50-48 vote in 2018 confirming Brett Kavanaugh, the 52-48
vote in 1991 confirming Clarence T homas, the 45-51 vote in 1970 rejecting G. Harrold Carswell, the 45 -55 vote in
1969 rejecting Clement Haynsworth Jr., the 54 -45 vote in 2017 confirming Neil Gorsuch, the 58-42 vote in 2006
confirming Samuel A. Alito Jr., and the 42 -58 vote in 1987 rejecting Robert H. Bork. Several of these votes are
presented in Figure 5, “ T en U.S. Supreme Court Nominations Approved by the Senate T hat Had Greatest Percentage
of Senators Voting Against Nomination.” Also noteworthy was the 45 -43 vote in 1968 rejecting a motion to end debate
on the nomination of Abe Fortas t o be Chief Justice; however, the roll call was not as close as the numbers by
themselves suggested, since passage of the motion required a two -thirds vote of the Members present and voting.
70 T he nomination of John G. Roberts was nearly opposed by a majority of Senators not belonging to the President’s
party. Roberts, nominated by President George W. Bush, had 22 Democrats vote in favor of his nomination and 22
Democrats vote in opposition to it.

was also the majority party in the Senate). In each of the other six cases, the majority of Senators
opposed to the nomination belonged to the minority party in the Senate (i.e., Democrats were the
minority party in 1986, 2006, 2017, and 2018, while Republicans were the minority party in 2009
and 2010).
Of the 16 nominations presented in Figure 3, 7 were approved by the Senate either unanimously
or with fewer than 10 nay votes—but the last nomination to fal into either one of these categories
was that of Stephen Breyer (nominated by President Clinton in 1994).

(1975 to Present)

Notes: This figure shows, for nominees whose nominations received a final floor vote since 1975, whether the
nomination was approved by the Senate. For nominations approved, the level of opposition —measured as the
number of nay votes received during a final floor vote on the nomination—is indicated (e.g., whether a
nomination received unanimous support on the floor or was voted against by a majority of Senators not
belonging to the President’s party).
Note that Senators not belonging to President G.W. Bush’s party (i.e., Democratic Senators) split 22-22 in voting
to confirm Mr. Roberts. This was the only 50/50 vote split for a political party’s Senators on one of the
nominations included in Figure 3.
Figure 4 provides some additional historical context for the number of nay votes received by the
six most recent nominations to the Court (Kavanaugh, Gorsuch, Kagan, Sotomayor, Alito, and
Roberts). Specifical y, the figure identifies, of the 35 nominations since 1945 that received a final
floor vote, the 10 nominations that received the greatest number of nay votes.71

71 Of the 35 nominations, 13 (37%) were approved by voice vote or unanimously by roll call vote—the most recent
being Anthony Kennedy’s nomination in 1988 (which was approved 97 -0). An additional 6 nominations (17%)

Nays During Final Vote
(1945 to Present)

Notes: This figure identifies the 10 Supreme Court nominations since 1945 that received the greatest number
of nay votes during the final floor vote on the nomination.
Of the 7 nominations that were approved, 6 were for individuals currently serving on the Court—
including the 5 most recent nominees (Kavanaugh, Gorsuch, Kagan, Sotomayor, and Alito).73 The
relatively high number of nay votes received by recent nominations approved by the Senate for

received fewer than 10 nays—the most recent being Stephen Breyer’s nomination in 1994 (which was appro ved 87-9).
72 Historically, individuals nominated to the Court have more likely than not been confirmed. From 1789 through 2018,
there were 132 individuals nominated to be an Associate Justice on the Supreme Court. Of the 132 individuals, 103
(78.0%) were confirmed by the Senate; 2 (1.5%) had their nominations withdrawn, were renominated to be Chief
Justice, and were confirmed by the Senate; 5 (3.8%) declined the nomination or, if confirmed, declined the appointment
to the Court; and the remaining 22 (16.7%) were not confirmed for one reason or another (e.g., the nominee’s
nomination was rejected by the Senate, the Senate took no action on the nomination, or the President withdrew the
nomination prior to Senate action). T he current nominee, Amy Coney Barrett, is the 133rd individual to be nominated to
be an Associate Justice on the Court.
During this same period, 21 individuals were nominated to be Chief Justice of the Court. Of the 21 individuals, 15
(71.4%) were confirmed by the Senate; 1 individual was conf irmed by the Senate, served as Chief Justice, stepped
down from service, was later renominated to be Chief Justice, and declined the nomination; 1 individual declined the
nomination; and another 4 (19.0%) individuals were not conf irmed for one reason or another (e.g., the nominee’s
nomination was rejected by the Senate or withdrawn by the President ). T he most recent instance of an individual not
being confirmed to the Chief Justice position was in 1968, when the Senate failed to invoke cloture on the nomination
of Abe Fortas to be Chief Justice (consequently, President Lyndon Johnson withdrew the nomination).
73 Additionally, William Rehnquist’s nomination to be Chief Justice in 1986 (33 nays) ranks in the top 10 in terms of
the number of nay votes received during a final floor vote.

the Supreme Court is atypical historical y (see further discussion below).74 Specifical y, the
relatively high number of nay votes received by recent nominations reflects greater opposition
than in the past by Senators not belonging to a President’s party to nominations to the Court.75
Percentage of Nays
The level of opposition to Supreme Court nominations approved by the Senate, as measured by
the percentage of Senators voting against a nomination, has been relatively greater in recent years
than in the past. Since 1789 there have been 51 nominations that received an up-or-down roll call
vote on the Senate floor that also resulted in the nomination being approved by the Senate76 Of
these 51 nominations, Figure 5 identifies the 10 for which the greatest percentage of Senators
voted to oppose it.77

74 Of the 35 nominations with a final floor vote during this period (1945 to the present), 24, or 69%, were approved by
roll call vote. T he average number of nay votes received for the 24 nominations was approximately 18, whi le the
median number of nay votes received was 11. Note that the number of nay votes received by each of the five most
recent nominations to the Court was greater than both the historical average and median number of nays received by a
nomination.
75 Specifically, the Kavanaugh nomination was supported by 49 Republicans and 1 Democrat; opposed by 48
Democrats. T he Gorsuch nomination was supported by 51 Republicans and 3 Democrats; opposed by 45 Democrats .
T he Kagan nomination was supported by 58 Democrats an d 5 Republicans; opposed by 1 Democrat and 36
Republicans. T he Sotomayor nomination was supported by 59 Democrats and 9 Republicans; opposed by 31
Republicans. T he Alito nomination was supported by 54 Republicans and 4 Democrats; opposed by 1 Republican an d
41 Democrats. T he Roberts nomination was supported by 56 Republicans and 22 Democrats; opposed by 22
Democrats. In contrast, Senators supported the nominations of Justices Scalia, Kennedy, Breyer, and Ginsburg either
unanimously or by overwhelming majorities within both parties. If a Senator was elected as an Independent, he is
included with the political party he caucused with in the numbers reported above.
76 Prior to the confirmation of T hurgood Marshall during the Lyndon Johnson presidency, it was relatively common for
Supreme Court nominees to be confirmed by voice vote. T he last nominee to be approved by the Senate in this manner
was Abe Fortas in 1965 (to the Associate Justice position vacated by Arthur Goldberg).
77 During this period of time, the Senate varied in size from 22 seats to 100 seats. For the purposes of this report, the
percentage of Senators voting in opposition to a nomination is calculated as a percentage of all Senators voting on a
nomination (not as a percentage of the number of Senate seats, although for practical purposes the number of Senators
voting on a nomination was typically the same as or similar to the number of Senate seats).

Notes: This figure identifies, of the 51 Supreme Court nominations since 1789 that were approved by rol cal
vote in the Senate (rather than by voice vote), the 10 nominations for which the percentage of Senators voting
against the nomination was greatest.
Of the 10 individuals listed in the figure, 5 are currently serving on the Court. The nominations of
Justices Kavanaugh, Thomas, Gorsuch, Alito, and Kagan were opposed by 49.0%, 48.0%, 45.5%,
42.0%, and 37.0% of Senators, respectively. Additional y, the nominations of two other current
Justices, Sonia Sotomayor and John Roberts, Jr., rank among the 20 nominations (of 51) that
received the most opposition (at 31.3% and 22.0%, respectively).78
Reconsideration of the Confirmation Vote
After a Senate vote to confirm a Supreme Court nomination, a Senator who voted on the
prevailing side may, under Senate Rule XXXI, move to reconsider the vote.79 Under the rule, only
one such motion to reconsider is in order on each nomination, and the tabling of the motion
prevents any subsequent attempt to reconsider. The Senate typical y deals with a motion to
reconsider a Supreme Court confirmation in one of two ways. Immediately following the vote to
confirm, a Senator may move to reconsider the vote, and the motion is promptly laid upon the
table by unanimous consent.80 Alternatively, wel before the vote to confirm, in a unanimous

78 T he most recent Supreme Court nominee approved by roll call vote and whose nomination received zero nay votes
was Anthony Kennedy in 1988.
79 “According to Senate Rule XXXI, any Senator who voted with the majority on the nomination has the option of
moving to reconsider a vote on the day of the vote or the next two days the Senate meets in executive session.” CRS
Report RL31980, Senate Consideration of Presidential Nom inations: Com m ittee and Floor Procedure , by Elizabeth
Rybicki (under subheading “ Consideration and Disposition”).
80 For example, immediately after the votes to confirm David Souter in 1990, Clarence T homas in 1991, John G.
Roberts Jr. in 2005, and Samuel A. Alito Jr. in 2006, a motion in each case was made to reconsider the vote, followed
by a motion “to lay that motion on the table,” which was agreed to without objection by the Senate. See Congressional

consent agreement, the Senate may provide that, in the event of confirmation, the motion to
reconsider be tabled.81 The Senate, it should be noted, has never adopted a motion to reconsider a
Supreme Court confirmation vote.
Calling Upon the Judiciary Committee to Further
Examine the Nomination
Sometimes, after a Supreme Court nomination has been reported, the Senate may delay
considering or voting on the nomination, in order to have the Senate Judiciary Committee address
new issues concerning the nominee or more fully examine issues that it addressed earlier.
Opponents of a nomination may also seek such delay, through recommittal of the nomination to
the committee, to defeat the nomination indirectly, by burying it in committee.
Recommittals of Supreme Court Nominations
Although the Senate has never adopted a motion to reconsider a Supreme Court nomination after
a confirmation vote, there have been at least eight preconfirmation vote attempts to recommit
Supreme Court nominations to the Judiciary Committee.82 Only two of those were successful. In
the first of these two instances, in 1873-1874, the nomination, after being recommitted, stal ed in
committee until it was withdrawn by the President. In the second instance, in 1925, the Judiciary
Committee re-reported the nomination, which the Senate then confirmed.
On December 15, 1873, on the second day of its consideration of the nomination of Attorney
General George H. Wil iams to be Chief Justice, the Senate ordered the nomination to be
recommitted to the Judiciary Committee.83 The nomination had been favorably reported by the
committee only four days earlier. During that four-day interval, however, various al egations were
made against Wil iams, including charges that while Attorney General he had used his office to
influence decisions profiting private companies in which he held interests.84 In ordering the
nomination to be recommitted, the Senate authorized the Judiciary Committee “to send for

p. S348. A slight variation of this procedure occurred in 2010, after the vote to confirm Elena Kagan, when the Senate’s
presiding officer, stated, “A motion to reconsider the vote is considered made and laid on the table.” Congressional
Record, daily edition, August 5, 2010, p. S6830.
81 For example, by unanimous consent the Senate in 1993, 1994, and 2009 agreed that the motion to reconsider be
tabled upon confirmation, respectively, of the Supreme Court nominations of Ruth Bader Ginsburg, Stephen G. Breyer,
and Sonia Sotomayor. See “ Unanimous-Consent Agreement,” Congressional Record, July 30, 1993, p. 17996;

Agreement —Executive Calendar,” Congressional Record, daily edition, August 5, 2009, pp. S8887-S8888.
82 Besides the successful attempts in the Senate to recommit the nominations of George H. Williams as Chief Justice in
1873 and Harlan F. Stone as Associate Justice in 1925, six other unsuccessful attempts to recommit Supreme Court
nominations were recorded—specifically, t he motions to recommit President Ulysses S. Grant’s nomination of Joseph
P. Bradley in 1870, President Warren G. Harding’s nomination of Pierce Butler in 1922, President Herbert Hoover’s
nomination of Charles Evans Hughes as Chief Justice in 1930, Presiden t Franklin D. Roosevelt’s nomination of Hugo

persons and papers”85—in evident reference to the new al egations made against the nominee.
Although the Judiciary Committee held hearings after the recommittal, it did not re-report the
nomination back to the Senate. Amid press reports of significant opposition to the nomination
both in the Judiciary Committee and the Senate as a whole,86 the nomination, at Wil iams’s
request, was withdrawn by President Ulysses S. Grant on January 8, 1874.87
On January 26, 1925, the Senate recommitted the Supreme Court nomination of Attorney General
Harlan F. Stone to the Judiciary Committee. Earlier, on January 21, the Judiciary Committee had
favorably reported the nomination to the Senate. However, one historian wrote, “Stone’s
unanimous Judiciary Committee approval ran into trouble when it reached the Senate floor.”88 A
principal point of concern to some Senators was the decision made by Stone as Attorney General
in December 1924 to expand a federal criminal investigation of Senator Burton K. Wheeler (D-
MT)—an investigation initiated by Stone’s predecessor as Attorney General, Harry Daugherty.
Stone’s most prominent critic on this point, Montana’s other Democratic Senator, Thomas J.
Walsh, demanded that the nomination be returned to the Judiciary Committee.89 By unanimous
consent the Senate agreed, ordering the nomination to be “rereferred to the Committee on the
Judiciary with a request that it be reported back to the Senate as soon as practicable.”90 Two days
after the recommittal, on January 28, the Judiciary Committee held hearings, with the nominee, at
the committee’s invitation, taking the then-unprecedented step of appearing before the committee.
Under lengthy cross examination by Senator Walsh and several other Senators, the nominee
defended his role in the Wheeler investigation.91 On February 2, 1925, the Judiciary Committee
again reported the Stone nomination favorably to the Senate, “by voice vote, without dissent,”92
and on February 5, 1925, the Senate confirmed Stone by a 71-6 vote.
Delay for Additional Committee Hearings Without Recommitting
the Nomination
In 1991, during debate on Supreme Court nominee Clarence Thomas, the Senate—without
recommitting the nomination to the Judiciary Committee—delayed its scheduled vote on the
nomination specifical y to al ow the committee time for additional hearings on the nominee. On
October 8, 1991, after four days of debate, the Senate, by unanimous consent, rescheduled its vote
on the Thomas nomination, from October 8 to October 15. The purpose of this delay was to al ow
the Judiciary Committee to hold hearings on sexual harassment al egations made against the
nominee by law professor Anita Hil , which had come to public light only after the Judiciary
Committee had ordered the Thomas nomination to be reported, without recommendation, on

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

September 27.93 Following three days of hearings, on October 11, 12, and 13, 1991, at which the
Judiciary Committee heard testimony from Judge Thomas, Professor Hil , and other witnesses,
the Senate, pursuant to its unanimous consent agreement, voted on the Thomas nomination as
scheduled, on October 15, 1991, confirming the nominee by a 52-48 vote.
After Senate Confirmation
Under the Constitution, the Senate alone votes on whether to confirm presidential nominations,
the House of Representatives having no formal involvement in the confirmation process. If the
Senate votes to confirm the nomination, the Secretary of the Senate then attests to a resolution of
confirmation and transmits it to the White House.94 In turn, the President signs a document, cal ed
a commission, official y appointing the individual to the Court. Next, the signed commission “is
returned to the Justice Department for engraving the date of appointment (determined by the
actual day the president signs the commission) and for the signature of the attorney general and
the placing of the Justice Department seal.”95 The department then arranges for expedited delivery
of the commission document to the new appointee.
Once the President has signed the commission, the incoming Justice may be sworn into office.96
In fact, however, the new Justice actual y takes two oaths of office—a judicial oath, as required
by the Judiciary Act of 1789,97 and a constitutional oath, which, as required by Article VI of the
Constitution, is administered to Members of Congress and al executive and judicial officers.
Until recently, the most common practice of new appointees had been to take their judicial oath in
private, usual y within the Court, and, as desired by the Presidents who nominated them, to take
their constitutional oaths in national y televised ceremonies at the White House.98 In 2009,

93 In October 8, 1991, floor remarks, Senate Majority Leader George J. Mitchell (D-ME) explained the need to delay
the T homas vote: “It is most unfortunate that we have been placed in this situation. But events which are unpredictable,
unplanned, and unfortunate can and frequently do intervene and cause a change in the plans of human beings. T hat has
now occurred in this matter, in my judgment. For that reason, I believe the action we have taken to change the time of
the scheduled vote until next T uesday [October 15], an d to give time for further inquiry into this matter by the Judiciary

Senate, Congressional Record, vol., 137, October 8, 1991, p. 25920.

96 Sometimes, the swearing into office occurs before the new Justice actually receives the commission document. T his,
for instance, happened in 2005 with Chief Justice appointee John G. Roberts Jr. Immediately after President George W.
Bush signed Roberts’s commission, the new Chief Justice was sworn into office—receiving his commission document
afterwards, when the Justice Department arranged for it to be hand-delivered to him at the Court.
97 T he Court itself regards the date a Justice takes the judicial oath as the beginning of his or her service, “for until that
oath is taken he/she is not vested with the prerogatives of the office.” Supreme Court, Supreme Court of the United
States, p. 23.
98 A news account noted the relatively recent advent of this pattern, when Justice Ruth Bader Ginsburg, on August 10,
1993, took her two oaths—the judicial oath, in private ceremony in the Court’s conference room, and the constitutional
oath, in a nationally televised ceremony in the White House’s East Room. “Supreme Court appointees,” the article
observed, “always have taken both oaths, but only since 1986, when Ronald Reagan held a ceremony for the investiture
of Associate Justice Antonin Scalia and Rehnquist, has the constitutional oath become part of a White House
ceremony.” Joan Biskupic, “Ginsburg Sworn In as 107th Justice and 2nd Woman on Supreme Court,” The Washington
Post, August 11, 1993, p. A6.
After Justice Ginsburg’s appointment, the next three Court appointees took the judicial oath in private (though each in a
different setting) and the constitutional oath in public (all at the White House). T he judicial oath was administered to
Stephen G. Breyer in private in 1994 by Chief Justice William H. Rehnquist at the latte r’s vacation home in

Supreme Court Appointment Process: Senate Debate and Confirmation Vote

however, in a departure from that practice, Supreme Court nominee Sonia Sotomayor, after
Senate confirmation, took both her constitutional and judicial oaths of office at the Supreme
Court—with the constitutional oath administered in a private ceremony, and the judicial oath
broadcast on television (“marking the first live coverage of such a ceremony in the institution’s
history”).99 This break from the practice of administering one of the oaths at the White House was
attributed, in one report, to President Obama “heeding concerns expressed by some justices—
most recently John Paul Stevens—that a White House ceremony sends the inappropriate message
that justices are beholden to their appointing president.”100 Following Sonia Sotomayor’s
example, President Obama’s second Supreme Court nominee, Elena Kagan, took both her
constitutional and judicial oaths of office at the Supreme Court as wel .101 In contrast, Neil
Gorsuch took the judicial oath of office at a public ceremony at the White House and the
constitutional oath of office in a private ceremony in the Justices’ Conference Room at the
Supreme Court building.102 Most recently, Brett Kavanaugh took, on the same day, both the
judicial oath of office and constitutional oath in a private ceremony in the Justices’ Conference
Room at the Court.103
Subsequently, the Court itself, in its courtroom, also affords public recognition to the new
Justice’s appointment, in a formal ceremony cal ed an “investiture,” at which the Justice is sworn
in yet again. This invitation-only event, for which reserved press seating is made available, is
attended by the Court’s other Justices, by family, friends, and former associates of the new
Justice, and by outside dignitaries who may include the President and the Attorney General.104

Samuel A. Alito Jr. in private at the Supreme Court’s conference room in 2006 by Chief Justice Roberts. On the same
occasions that they took their judicial oaths in private, Roberts and Alito took their constitutional oaths as well —while,
however, also taking their constitutional oaths a second time, in televised White House ceremonies.
99 Amy Goldstein, “Sotomayor Reaches Pinnacle of Law with Historic Oath,” The Washington Post, August 9, 2009, p.
A3. Chief Justice John G. Roberts Jr., a Court news release specified, would administer both the constitutional oath, “in
a private ceremony in the Justices’ Conference Room attended by members of the Sotomayor family,” and the judicial
oath, in the Court’s East Conference Room “before a small gathering of Judge Sotomayor’s family and friends,”

justice from Clarence T homas on has been televised, but those events took place at the White House, not the Court. A
White House source indicated Friday [August 7] that notwith standing that practice, President Barack Obama made it
clear from the start that, out of respect for the Court’s independence, the entire ceremony should be at the Court, not the
White House. As The National Law Journal reported last week, that’s likely to be welcome news at the Court, where
justices over the years have disapproved of White House oath -taking.” T ony Mauro, “ Cameras Come to the Supreme
