Justice Ruth Bader Ginsburg as a Deciding Vote  September 25, 2020 
on the Supreme Court: Select Data 
Michael John Garcia 
On September 18, 2020, Justice Ruth Bader Ginsburg, the second woman to serve on the 
Section Research Manager 
Supreme Court of the United States, passed away at the age of eighty-seven, vacating a seat on 
  
the High Court that she had held for twenty-seven years. Over more than a quarter-century on the 
Kate R. Bowers 
Court, Justice Ginsburg encountered nearly every major flashpoint of modern American legal 
Legislative Attorney 
debate, including many issues on which the sitting Justices were closely divided.  
  
As Justice Ginsburg’s predecessor Justice Byron White observed, “every time a new justice 
 
comes to the Supreme Court, it’s a different court.” It is likely that Justice Ginsburg’s views in 
closely decided Supreme Court cases will be of interest to Members of Congress as the Senate considers a nominee to fill her 
seat, as those cases may illustrate how the Court could change in her absence. Many recent retrospectives of Justice 
Ginsburg’s career have highlighted her dissenting opinions in cases where she and other Justices in the more liberal wing of 
the Court were at odds with a more conservative majority. But focusing on Justice Ginsburg’s dissents may paint an 
incomplete picture of her influence on the outcome of Supreme Court cases and the effect that her replacement could have 
upon the trajectory of the Court’s jurisprudence. Justice Ginsburg frequently authored or joined majority opinions for the 
Court, and she was a deciding vote for the majority position in numerous closely divided cases. While Justice Ginsburg was 
less likely to be a deciding vote than Justice Anthony Kennedy, who retired from the bench in 2018 after having been the 
pivotal vote in 186 cases during the Roberts Court era, she was still a deciding vote in 112 cases from the date of Chief 
Justice Roberts’s elevation to the Court to the date of her passing. This report includes several tables relating to cases where 
Justice Ginsburg cast a deciding vote in the Roberts Court era. The tables compile cases involving constitutional questions, 
issues governed by statute (including not only questions of statutory interpretation but also agency actions taken pursuant to 
statutory authority, as well as judicial and executive branch rules and actions concerning procedural matters governed by 
statute), and other matters.

Justice Ruth Bader Ginsburg as a Deciding Vote on the Supreme Court: Select Data 
 
n September 18, 2020, Justice Ruth Bader Ginsburg, the second woman to serve on the 
Supreme Court of the United States, passed away at the age of eighty-seven, vacating a 
O seat on the High Court that she had held for twenty-seven years.1 Over more than a 
quarter-century on the Court, Justice Ginsburg encountered nearly every major flashpoint of 
modern American legal debate, including many issues on which the sitting Justices were closely 
divided.2 
As Justice Ginsburg’s predecessor Justice Byron White observed, “every time a new justice 
comes to the Supreme Court, it’s a different court.”3 It is likely that Justice Ginsburg’s views in 
closely decided Supreme Court cases wil  be of interest to Members of Congress as the Senate 
considers a nominee to fil  her seat, as those cases may il ustrate how the Court could change in 
her absence. Many recent retrospectives of Justice Ginsburg’s career have highlighted her 
dissenting opinions in cases where she and other Justices in the more liberal wing of the Court 
were at odds with a more conservative majority.4 But focusing on Justice Ginsburg’s dissents may 
paint an incomplete picture of her influence on the outcome of Supreme Court cases and the 
effect that her replacement could have upon the trajectory of the Court’s jurisprudence. Justice 
Ginsburg frequently authored or joined majority opinions for the Court, and she was an essential 
vote for the majority in numerous closely divided cases.5 While Justice Ginsburg was less likely 
to be a deciding vote in closely divided cases than Justice Anthony Kennedy, who retired from the 
bench in 2018 after having been the pivotal vote in 186 cases during the Roberts Court era,6 she

jurisprudence  on sex and gender issues,  while  observing that “ [h]er influence went far beyond gender cases.  . . . As  the 
frequency and barbed  tone of her dissents increased  later in her career, she became a liberal icon, sometimes dubbed 
‘T he Notorious RBG’”); Richard  Wolf, Justice Ruth Bader Ginsburg’s Top Opinions and Dissents,  from VMI  to Voting

presence belied  her titanic influence on the law, first as the nation’s preeminent litigator for women’s rights, and more 
recently as the leader of the high court’s liberal bloc, where  she served as  a bulwark  against an increasingly 
conservative majority.”). 
5 According to one study, Justice Ginsburg  authored more majority opinions than any other Justice on the bench during 
the same period as her. Adam  Feldman, Justice Ginsburg Leaves a Lasting Legacy on the Court, EMPIRICAL SCOT US 
(Sept. 19, 2020), https://empiricalscotus.com/2020/09/19/justice-ginsburg-leaves-a-lasting-legacy-on-the-court/. And 
even in the Roberts Court era, when Justice Ginsburg  was  somewhat more likely to be in  dissent than in earlier years, 
she was  still part of the deciding majority in nearly 80 percent of the cases considered  by the Court . See id. (including 
tables showing  that Justice Ginsburg  was  in the majority in 865 cases during  the Rehnquist Court era (roughly 81.4% of 
considered  cases from the October 1993 term through the October 2004 term), compared to 902 cases since Chief 
Justice Roberts’s elevation to the Court (roughly 78.6% of the cases decided  from the October 2005 term onward)). 
6 See CRS  Report R45256, Justice Anthony Kennedy: His Jurisprudence and the Future of the Court, by Andrew 
Nolan, Kevin M. Lewis,  and Valerie  C. Brannon, at Appendix (using  same methodology as this report to identify cases 
in which Justice Kennedy was  a deciding  vote from the October 2015 term until Justice Kennedy’s retirement from the 
High Court in 2018).

was stil  a deciding vote in 112 cases from the date of Chief Justice Roberts’s elevation to the 
Court to the date of her passing.7 
This report includes several tables relating to cases where Justice Ginsburg cast a deciding vote in 
the Roberts Court era. For purposes of the tables, Justice Ginsburg is considered to have cast a 
“deciding vote” any time she authored or joined a majority or plurality opinion or concurred in 
the result of a case where the Justices were divided either 5-4, 5-3, 4-3, or 4-2 on one or more 
issues.8 Per curiam opinions are included only if they resolved an appeal pending before the 
Court.9 
Table 1 identifies cases primarily centering on questions of constitutional interpretation in which 
Justice Ginsburg cast a deciding vote. Table 2 includes cases mainly addressing questions of 
statutory interpretation—including agency actions taken pursuant to statutory authority, as wel  as 
judicial  and executive branch rules and actions concerning procedural matters governed by 
statute—in which Justice Ginsburg cast a deciding vote. Table 3 compiles closely divided cases 
that do not fal  neatly into either of the prior tables (e.g., cases centering on interstate compacts or 
the interpretation of treaties with Indian tribes). Each Table also identifies (1) the statute, 
constitutional provision, or other source of law primarily at issue in the case; and (2) Justice 
Ginsburg’s position on the key issue in the case. The cases in these three tables are listed 
alphabetical y  by year, and are categorized under the following subject areas: 
  Abortion Law 
  Administrative Law 
  Business Law (including issues arising in antitrust, banking, bankruptcy and debt 
collection, consumer law, contract law, intel ectual property law, and securities 
law) 
  Civil  Rights Law (including issues arising under the Fourteenth Amendment and 
civil actions brought under 42 U.S.C. §1983) 
                                              
7 Cases  preceding Chief Justice Roberts’s elevation to the Supreme Court are less  likely to reflect the current dynamics 
of the Court —and, by  extension, are less likely to illuminate the effect that Justice Ginsburg’s  successor  might have on 
those dynamics. See, e.g., Caitlin E. Borgmann, Holding Legislatures  Constitutionally Accountable Through Facial 
Challenges, 36 HASTINGS CONST. L.Q. 563, 589 (2009) (opining that “ the Roberts Court has heralded  a rightward 
ideological  shift on the bench, from a split in which Justice  O’Connor served as the swing  vote and Justice Kennedy 
was  counted in the conservative half, to one in which a solidly conservative four face off against the four more liberal 
Justices,  with Justice  Kennedy functioning as the swing  vote”); Amelia T homson-DeVeaux, The Supreme Court Might 
Have Three Swing Justices Now,  FIVET HIRTYEIGHT (July 2, 2019) (positing that with Justice Kennedy’s retirement and 
the ascension of Justices  Gorsuch  and Kavanaugh to the High Court in recent years, there may be “ a newly cemented 
conservative majority on the court” and that while these new Justices  shifted the Court’s center rightward, they are not 
uniform in their individual approach to issues,  suggesting  that “the days of a single  ‘swing’   justice may be  over”). 
8 T hese cases were  obtained using  three methods: 
• searching Washington University School of Law’s Supreme Court Database for 5-4, 5-3, 4-3, and 4-2 cases in 
which Justice  Ginsburg  voted with the majority or plurality from the October 2005 through October 2019 
terms; 
• referencing SCOTUSBlog’s  “Stat Pack” compendia of 5-4 cases from October Term 2005 onward, available at 
http://www.scotusblog.com/reference/stat -pack/ (last visited Sept. 23, 2020); and 
• searching LexisNexis’s database of Supreme Court cases from October 2005 onward in which one or more 
Justices  recused  themselves. 
9 For example, the tally excludes  Laboratory Corp. of America Holdings v. Metabolite Laboratories, Inc., 548 U.S.  124 
(2006) (per curiam opinion joined by Alito, Ginsburg,  Kennedy, Scalia  and T homas, JJ., dismissing  writ of certiorari as 
improvidently granted).

For purposes of brevity, no more than two subject areas are identified as relevant to a particular 
case. While these categorizations are intended to provide a helpful guide to readers in identifying 
the subject matters of decisions, they do not necessarily reflect the full range of legal issues a 
judicial  opinion may involve. 
Table 1, Table 2, and Table 3 also identify the composition of Justices hearing a listed case, 
dividing the members of the Court who participated in the case into two categories: (1) Justices 
making up the majority or controlling plurality, including those who concurred with the Court’s 
judgment; and (2) Justices who dissented in whole or in part from the judgment of the Court. The 
author of the primary opinion is designated with an asterisk (*). Authors of concurring and 
dissenting opinions are identified with plus signs (+). Justice Ginsburg’s name has been 
capitalized throughout for the reader’s convenience. For ease of reference, Justices are listed in 
alphabetical order, rather than order of seniority.

a.  In the 62 cases listed in Table 1, the three most common voting groups of Justices in the majority  or control ing plurality were (1) Breyer,  GINSBURG, Kagan, 
Kennedy, and Sotomayor (21 cases); (2) Breyer,  GINSBURG, Kennedy, Souter, and Stevens (11 cases); and (3) Breyer,  GINSBURG, Kagan, Roberts, and Sotomayor 
(4 cases).  
b.  The separate elements  of the Court’s holding in National Federation of Independent Business v. Sebelius,  567 U.S. 519 (2012), were each joined by a distinct group 
of Justices. Chief Justice Roberts and Justices Scalia, Kennedy, Thomas, and Alito  agreed that the individual mandate was not au thorized under the Commerce 
Clause. 
Justices Scalia, Kennedy, Thomas, and Alito did not join in Chief Justice Roberts’s  opinion, however,  but arrived  at the same conclusion in a dissenting opinion. 567 
U.S. at 646 (Scalia, J., joined by Kennedy, Thomas, and Alito  JJ.). Chief Justice Roberts, joined by Justices Ginsburg, Breyer,  Sotomayor,  and Kagan, agreed that the 
individual mandate was a valid exercise  of Congress’s  taxing power.  Id. at 574. Justice Ginsburg wrote a separate partial concurrence, in which she also would have 
upheld the Affordable Care Act’s individual mandate under both the taxing power and the Commerce  Clause, and the Medicaid expansion provision  under the 
Spending Clause. Id. at 589 (Ginsburg, J., joined by Breyer,  Kagan, and Sotomayor,  JJ.). Justice Sotomayor  joined in the entirety of Justice Ginsburg’s opinion, and 
Justices Breyer  and Kagan joined in the opinion as to the individual mandate but not to the Medicaid expansion provision.

a.  In the 45 cases listed in Table 2, the three most common voting groups of Justices in the majority  or control ing plurality were (1) Breyer,  GINSBURG, Kagan, 
Kennedy, and Sotomayor (8 cases); (2) Breyer,  GINSBURG, Kennedy, Souter, and Stevens (7 cases); and (3) Breyer,  GINSBURG, Kagan, Roberts, and Sotomayor  (4 
cases).  
b.  The Supreme Court fractured markedly  in League of United American  Latin American  Citizens v. Perry,  resulting in six different opinions that reached a variety of 
different legal conclusions. This chart therefore  reflects only the legal positions  adopted in a majority  opinion joined by J ustice Ginsburg. In addition to that opinion, 
Justice Ginsburg also was part of a three-Justice plurality that concluded that appel ants did not establish that a state legislature’s  decision to override  a valid, court-
drawn restricting plan used political  classifications in a way that caused unconstitutional political gerrymanders.  548 U.S. 399, 439 (Kennedy, J., joined  by Souter and 
Ginsburg, JJ.). See also id. at 492-93 (Roberts, C.J.,  joined by Alito,  J., concurring in judgment regarding statewide chal enge).
