The Supreme Court of the United States, sometimes abbreviated SCOTUS, is a one-of-a-kind institution. While a look at the Supreme Court typically focuses on the nine justices themselves, they represent only the top layer of an entire branch of government that includes many administrators, lawyers, and assistants who contribute to and help run the overall judicial system. The Court has its own set of rules for choosing cases, and it follows a unique set of procedures for hearing them. Its decisions not only affect the outcome of the individual case before the justices, but they also create lasting impacts on legal and constitutional interpretation for the future.


The original court in 1789 had six justices, but Congress set the number at nine in 1869, and it has remained there ever since. There is one chief justice, who is the lead or highest-ranking judge on the Court, and eight associate justices. All nine serve lifetime terms, after successful nomination by the president and confirmation by the Senate.

The current court is fairly diverse in terms of gender, religion (Christians and Jews), ethnicity, and ideology, as well as length of tenure. Some justices have served for three decades, whereas others were only recently appointed by President Obama. Figure lists the names of the eight justices serving on the Court as of April 2016, along with their year of appointment and the president who nominated them.

A chart titled “Appointments of the Current Supreme Court Justices”. A horizontal timeline runs through the center of the chart. Starting from the left, the first point marked on the line is labeled “Anthony Kennedy, Appointed by Ronald Regan in 1988”. The label is colored blue and red to indicate both liberal and conservative. The second point is labeled “Clarence Thomas, Appointed by George H. W. Bush in 1991”. The label is colored red to indicate conservative. The third point is labeled “Ruth Bader Ginsburg, Appointed by Bill Clinton in 1993”. The label is colored blue to indicate liberal. The fourth point is labeled “Stephen Breyer, Appointed by Bill Clinton in 1994”. The label is colored blue to indicate liberal. The fifth point is labeled “John Roberts (Chief), Appointed by George W. Bush in 2005”. The label is colored red to indicate conservative. The sixth point is labeled “Samuel Alito, Appointed by George W. Bush in 2006”. The label is colored red to indicate conservative. The seventh point is labeled “Sonia Sotomayor, Appointed by Barack Obama in 2009”. The label is colored blue to indicate liberal. The eight point is labeled “Elena Kagan, Appointed by Barack Obama in 2010”. The label is colored blue to indicate liberal. The last point is labeled with an uncolored question mark.

With the death of Associate Justice Antonin Scalia in February 2016, there remain three current justices who are considered part of the Court’s more conservative wing—Chief Justice Roberts and Associate Justices Thomas and Alito, while four are considered more liberal-leaning—Justices Ginsburg, Breyer, Sotomayor, and Kagan (Figure). Justice Kennedy has become known as the “swing” vote, particularly on decisions like the Court’s same-sex marriage rulings in 2015, because he sometimes takes a more liberal position and sometimes a more conservative one. The replacement for Scalia’s spot on the court could swing many key votes in a moderate or liberal direction.

In fact, none of the justices works completely in an ideological bubble. While their numerous opinions have revealed certain ideological tendencies, they still consider each case as it comes to them, and they don’t always rule in a consistently predictable or expected way. Furthermore, they don’t work exclusively on their own. Each justice has three or four law clerks, recent law school graduates who temporarily work for him or her, do research, help prepare the justice with background information, and assist with the writing of opinions. The law clerks’ work and recommendations influence whether the justices will choose to hear a case, as well as how they will rule. As the profile below reveals, the role of the clerks is as significant as it is varied.

Profile of a United States Supreme Court Clerk

A Supreme Court clerkship is one of the most sought-after legal positions, giving “thirty-six young lawyers each year a chance to leave their fingerprints all over constitutional law.”Dahlia Lithwick. “Who Feeds the Supreme Court?” September 14, 2015. A number of current and former justices were themselves clerks, including Chief Justice John Roberts, Justices Stephen Breyer and Elena Kagan, and former chief justice William Rehnquist.

Supreme Court clerks are often reluctant to share insider information about their experiences, but it is always fascinating and informative to hear about their jobs. Former clerk Philippa Scarlett, who worked for Justice Stephen Breyer, describes four main responsibilities:“Role of Supreme Court Law Clerk: Interview with Philippa Scarlett.” IIP Digital. United States of America Embassy. (March 1, 2016).

Review the cases: Clerks participate in a “cert. pool” (short for writ of certiorari, a request that the lower court send up its record of the case for review) and make recommendations about which cases the Court should choose to hear.

Prepare the justices for oral argument: Clerks analyze the filed briefs (short arguments explaining each party’s side of the case) and the law at issue in each case waiting to be heard.

Research and draft judicial opinions: Clerks do detailed research to assist justices in writing an opinion, whether it is the majority opinion or a dissenting or concurring opinion.

Help with emergencies: Clerks also assist the justices in deciding on emergency applications to the Court, many of which are applications by prisoners to stay their death sentences and are sometimes submitted within hours of a scheduled execution.

The Supreme Court begins its annual session on the first Monday in October and ends late the following June. Every year, there are literally thousands of people who would like to have their case heard before the Supreme Court, but the justices will select only a handful to be placed on the docket, which is the list of cases scheduled on the Court’s calendar. The Court typically accepts fewer than 2 percent of the as many as ten thousand cases it is asked to review every year.“Supreme Court Procedures.” United States Courts. (March 1, 2016).

Case names, written in italics, list the name of a petitioner versus a respondent, as in Roe v. Wade, for example.Roe v. Wade, 410 U.S. 113 (1973). For a case on appeal, you can tell which party lost at the lower level of court by looking at the case name: The party unhappy with the decision of the lower court is the one bringing the appeal and is thus the petitioner, or the first-named party in the case. For example, in Brown v. Board of Education (1954), Oliver Brown was one of the thirteen parents who brought suit against the Topeka public schools for discrimination based on racial segregation.

Most often, the petitioner is asking the Supreme Court to grant a writ of certiorari, a request that the lower court send up its record of the case for review. Once a writ of certiorari (cert. for short) has been granted, the case is scheduled on the Court’s docket. The Supreme Court exercises discretion in the cases it chooses to hear, but four of the nine Justices must vote to accept a case. This is called the Rule of Four.

For decisions about cert., the Court’s Rule 10 (Considerations Governing Review on Writ of Certiorari) takes precedence.”Rule 10. Considerations Governing Review on Certiorari.” Rules of the Supreme Court of the United States. Adopted April 19, 2013, Effective July 1, 2013. The Court is more likely to grant certiorari when there is a conflict on an issue between or among the lower courts. Examples of conflicts include (1) conflicting decisions among different courts of appeals on the same matter, (2) decisions by an appeals court or a state court conflicting with precedent, and (3) state court decisions that conflict with federal decisions. Occasionally, the court will fast-track a case that has special urgency, such as Bush v. Gore in the wake of the 2000 election.Bush v. Gore, 531 U.S. 98 (2000).

Past research indicated that the amount of interest-group activity surrounding a case before it is granted cert. has a significant impact on whether the Supreme Court puts the case on its agenda. The more activity, the more likely the case will be placed on the docket.Gregory A. Caldeira and John R. Wright. 1988. “Organized Interests and Agenda-Setting in the U.S. Supreme Court,” American Political Science Review 82: 1109–1128. But more recent research broadens that perspective, suggesting that too much interest-group activity when the Court is considering a case for its docket may actually have diminishing impact and that external actors may have less influence on the work of the Court than they have had in the past.Gregory A. Caldeira, John R. Wright, and Christopher Zorn. 2012. “Organized Interests and Agenda Setting in the U.S. Supreme Court Revisited.” Presentation at the Second Annual Conference on Institutions and Lawmaking, Emory University. Still, the Court takes into consideration external influences, not just from interest groups but also from the public, from media attention, and from a very key governmental actor—the solicitor general.

The solicitor general is the lawyer who represents the federal government before the Supreme Court: He or she decides which cases (in which the United States is a party) should be appealed from the lower courts and personally approves each one presented (Figure). Most of the cases the solicitor general brings to the Court will be given a place on the docket. About two-thirds of all Supreme Court cases involve the federal government.“About the Office.” Office of the Solicitor General. The United States Department of Justice. (March 1, 2016).

The solicitor general determines the position the government will take on a case. The attorneys of his or her office prepare and file the petitions and briefs, and the solicitor general (or an assistant) presents the oral arguments before the Court.

Thurgood Marshall (a), who later served on the Supreme Court, was appointed solicitor general by Lyndon Johnson and was the first African American to hold the post. Donald B. Verrilli Jr. (b) is the forty-sixth solicitor general of the United States, starting his term of office in June 2011 when Elena Kagan left the post to join the Supreme Court.

In other cases in which the United States is not the petitioner or the respondent, the solicitor general may choose to intervene or comment as a third party. Before a case is granted cert., the justices will sometimes ask the solicitor general to comment on or file a brief in the case, indicating their potential interest in getting it on the docket. The solicitor general may also recommend that the justices decline to hear a case. Though research has shown that the solicitor general’s special influence on the Court is not unlimited, it remains quite significant. In particular, the Court does not always agree with the solicitor general, and “while justices are not lemmings who will unwittingly fall off legal cliffs for tortured solicitor general recommendations, they nevertheless often go along with them even when we least expect them to.”Ryan C. Black and Ryan J. Owens. “Solicitor General Influence and the United States Supreme Court.” Vanderbilt University. (March 1, 2016).

Some have credited Donald B. Verrilli, the current solicitor general, with holding special sway over the five-justice majority ruling on same-sex marriage in June 2015. Indeed, his position that denying homosexuals the right to marry would mean “thousands and thousands of people are going to live out their lives and go to their deaths without their states ever recognizing the equal dignity of their relationships” became a foundational point of the Court’s opinion, written by Justice Kennedy.Mark Joseph Stern., “If SCOTUS Decides in Favor of Marriage Equality, Thank Solicitor General Don Verrilli,” April 29, 2015. With such power over the Court, the solicitor general is sometimes referred to as “the tenth justice.”


Once a case has been placed on the docket, briefs, or short arguments explaining each party’s view of the case, must be submitted—first by the petitioner putting forth his or her case, then by the respondent. After initial briefs have been filed, both parties may file subsequent briefs in response to the first. Likewise, people and groups that are not party to the case but are interested in its outcome may file an amicus curiae (“friend of the court”) brief giving their opinion, analysis, and recommendations about how the Court should rule. Interest groups in particular can become heavily involved in trying to influence the judiciary by filing amicus briefs—both before and after a case has been granted cert. And, as noted earlier, if the United States is not party to a case, the solicitor general may file an amicus brief on the government’s behalf.

With briefs filed, the Court hears oral arguments in cases from October through April. The proceedings are quite ceremonial. When the Court is in session, the robed justices make a formal entrance into the courtroom to a standing audience and the sound of a banging gavel. The Court’s marshal presents them with a traditional chant: “The Honorable, the Chief Justice and the Associate Justices of the Supreme Court of the United States. Oyez! Oyez! Oyez! [Hear ye!] All persons having business before the Honorable, the Supreme Court of the United States, are admonished to draw near and give their attention, for the Court is now sitting. God save the United States and this Honorable Court!”“The Court and its Procedures.” Supreme Court of the United States. May 26, 2015. It has not gone unnoticed that the Court, which has defended the First Amendment’s religious protection and the traditional separation of church and state, opens its every public session with a mention of God.

During oral arguments, each side’s lawyers have thirty minutes to make their legal case, though the justices often interrupt the presentations with questions. The justices consider oral arguments not as a forum for a lawyer to restate the merits of his or her case as written in the briefs, but as an opportunity to get answers to any questions they may have.“Supreme Court Procedures.” United States Courts. (March 1, 2016). When the United States is party to a case, the solicitor general (or one of his or her assistants) will argue the government’s position; even in other cases, the solicitor general may still be given time to express the government’s position on the dispute.

When oral arguments have been concluded, the justices have to decide the case, and they do so in conference, which is held in private twice a week when the Court is in session and once a week when it is not. The conference is also a time to discuss petitions for certiorari, but for those cases already heard, each justice may state his or her views on the case, ask questions, or raise concerns. The chief justice speaks first about a case, then each justice speaks in turn, in descending order of seniority, ending with the most recently appointed justice.“Supreme Court Procedures.” United States Courts. (March 1, 2016). The judges take an initial vote in private before the official announcement of their decisions is made public.

Oral arguments are open to the public, but cameras are not allowed in the courtroom, so the only picture we get is one drawn by an artist’s hand, an illustration or rendering. Cameras seem to be everywhere today, especially to provide security in places such as schools, public buildings, and retail stores, so the lack of live coverage of Supreme Court proceedings may seem unusual or old-fashioned. Over the years, groups have called for the Court to let go of this tradition and open its operations to more “sunshine” and greater transparency. Nevertheless, the justices have resisted the pressure and remain neither filmed nor photographed during oral arguments.Jonathan Sherman. “End the Supreme Court's Ban on Cameras.” New York Times. 24 April 2015.


A unique institution, the U.S. Supreme Court today is an interesting mix of the traditional and the modern. On one hand, it still holds to many of the formal traditions, processes, and procedures it has followed for many decades. Its public proceedings remain largely ceremonial and are never filmed or photographed. At the same time, the Court has taken on new cases involving contemporary matters before a nine-justice panel that is more diverse today than ever before. When considering whether to take on a case and then later when ruling on it, the justices rely on a number of internal and external players who assist them with and influence their work, including, but not limited to, their law clerks, the U.S. solicitor general, interest groups, and the mass media.
