Established by Article Three of the United States Constitution, the composition and procedures of the Supreme Court were initially established by the 1st Congress through the Judiciary Act of 1789. As later set by the Judiciary Act of 1869, the Court consists of the Chief Justice of the United States and eight associate justices. Each justice has lifetime tenure, meaning they remain on the Court until they resign, retire, die, or are removed from office.^[4] When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice. Each justice has a single vote in deciding the cases argued before it. When in majority, the chief justice decides who writes the opinion of the court; otherwise, the most senior justice in the majority assigns the task of writing the opinion.

The Court meets in the Supreme Court Building in Washington, D.C. Its law enforcement arm is the Supreme Court Police.

A term of the Supreme Court commences on the first Monday of each October, and continues until June or early July of the following year. Each term consists of alternating periods of around two weeks known as "sittings" and "recesses". Justices hear cases and deliver rulings during sittings; they discuss cases and write opinions during recesses.

Case selection

Nearly all cases come before the court by way of petitions for writs of certiorari, commonly referred to as "cert". The Court may review any case in the federal courts of appeals "by writ of certiorari granted upon the petition of any party to any civil or criminal case".^[163] The Court may only review "final judgments rendered by the highest court of a state in which a decision could be had" if those judgments involve a question of federal statutory or constitutional law.^[164] The party that appealed to the Court is the petitioner and the non-mover is the respondent. All case names before the Court are styled petitioner v. respondent, regardless of which party initiated the lawsuit in the trial court. For example, criminal prosecutions are brought in the name of the state and against an individual, as in State of Arizona v. Ernesto Miranda. If the defendant is convicted, and his conviction then is affirmed on appeal in the state supreme court, when he petitions for cert the name of the case becomes Miranda v. Arizona.

There are situations where the Court has original jurisdiction, such as when two states have a dispute against each other, or when there is a dispute between the United States and a state. In such instances, a case is filed with the Supreme Court directly. Examples of such cases include United States v. Texas, a case to determine whether a parcel of land belonged to the United States or to Texas, and Virginia v. Tennessee, a case turning on whether an incorrectly drawn boundary between two states can be changed by a state court, and whether the setting of the correct boundary requires Congressional approval. Although it has not happened since 1794 in the case of Georgia v. Brailsford,^{[165]A term of the Supreme Court commences on the first Monday of each October, and continues until June or early July of the following year.

Although it has not happened since 1794 in the case of Georgia v. Brailsford,^[165] parties in an action at law in which the Supreme Court has original jurisdiction may request that a jury determine issues of fact.^[166] Georgia v. Brailsford remains the only case in which the court has empaneled a jury, in this case a special jury.^[167] Two other original jurisdiction cases involve colonial era borders and rights under navigable waters in New Jersey v. Delaware, and water rights between riparian states upstream of navigable waters in Kansas v. Colorado.

A cert petition is voted on at a session of the court called a conference. A conference is a private meeting of the nine Justices by themselves; the public and the Justices' clerks are excluded. The rule of four permits four of the nine justices to grant a writ of certiorari. If it is granted, the case proceeds to the briefing stage; otherwise, the case ends. Except in death penalty cases and other cases in which the Court orders briefing from the respondent, the respondent may, but is not required to, file a response to the cert petition.

The court grants a petition for cert only for "compelling reasons", spelled out in the court's Rule 10. Such reasons include:

When a conflict of interpretations arises from differing interpretations of the same law or constitutional provision issued by different federal circuit courts of appeals, lawyers call this situation a "circuit split". If the court votes to deny a cert petition, as it does in the vast majority of such petitions that come before it, it does so typically without comment. A denial of a cert petition is not a judgment on the merits of a case, and the decision of the lower court stands as the case's final ruling.

To manage the high volume of cert petitions received by the Court each year (of the more than 7,000 petitions the Court receives each year, it will usually request briefing and hear oral argument in 100 or fewer), the Court employs an internal case management tool known as the "cert pool". Currently, all justices except for Justices Alito and Gorsuch participate in the cert pool.^{cert pool". Currently, all justices except for Justices Alito and Gorsuch participate in the cert pool.[168][169][170][171]}

When the Court grants a cert petition, the case is set for oral argument. Both parties will file briefs on the merits of the case, as distinct from the reasons they may have argued for granting or denying the cert petition. With the consent of the parties or approval of the Court, amici curiae, or "friends of the court", may also file briefs. The Court holds two-week oral argument sessions each month from October through April. Each side has thirty minutes to present its argument (the Court may choose to give more time, though this is rare),^[172] and during that time, the Justices may interrupt the advocate and ask questions. The petitioner gives the first presentation, and may reserve some time to rebut the respondent's arguments after the respondent has concluded. Amici curiae may also present oral argument on behalf of one party if that party agrees. The Court advises counsel to assume that the Justices are familiar with and have read the briefs filed in a case.

Supreme Court bar

In order to plead before the court, an attorney must first be admitted to the court's bar. Approximately 4,000 lawyers join the bar each year. The bar contains an estimated 230,000 members. In reality, pleading is limited to several hundred attorneys. The rest join for a one-time fee of $200, earning the court about $750,000 annually. Attorneys can be admitted as either individuals or as groups. The group admission is held before the current justices of the Supreme Court, wherein the chief justice approves a motion to admit the new attorneys.^[173] Lawyers commonly apply for the cosmetic value of a certificate to display in their office or on their resume. They also receive access to better seating if they wish to attend an oral argument.^[174] Members of the Supreme Court Bar are also granted access to the collections of the Supreme Court Library.^[173] Lawyers commonly apply for the cosmetic value of a certificate to display in their office or on their resume.

Decision

At the conclusi

At the conclusion of oral argument, the case is submitted for decision. Cases are decided by majority vote of the Justices. It is the Court's practice to issue decisions in all cases argued in a particular term by the end of that term. Within that term, however, the Court is under no obligation to release a decision within any set time after oral argument. At the conclusion of oral argument, the Justices retire to another conference at which the preliminary votes are tallied, and the most senior Justice in the majority assigns the initial draft of the Court's opinion to a Justice on his or her side. Drafts of the Court's opinion, as well as any concurring or dissenting opinions,^[176] circulate among the Justices until the Court is prepared to announce the judgment in a particular case. Since recording devices are banned inside the courtroom of the Supreme Court Building, the delivery of the decision to the media is done via paper copies and is known as the Running of the Interns.^[177][178]

It is possible that, through recusals or vacancies, the Court divides evenly on a case. If that occurs, then the decision of the court below is affirmed, but does not establish binding precedent. In effect, it results in a return to the status quo ante. For a case to be heard, there must be a quorum of at least six justices.^[179] If a quorum is not available to hear a case and a majority of qualified justices believes that the case cannot be heard and determined in the next term, then the judgment of the court below is affirmed as if the Court had been evenly divided. For cases brought to the Supreme Court by direct appeal from a United States District Court, the chief justice may order the case remanded to the appropriate U.S. Court of Appeals for a final decision there.^[180] This has only occurred once in U.S. history, in the case of United States v. Alcoa (1945).^[181]

The Court's opinions are published in three stages. First, a slip opinion is made available on the Court's web site and through other outlets. Next, several opinions and lists of the court's orders are bound together in paperback form, called a preliminary print of United States Reports, the official series of books in which the final version of the Court's opinions appears. About a year after the preliminary prints are issued, a final bound volume of U.S. Reports is issued. The individual volumes of U.S. Reports are numbered so that users may cite this set of reports (or a competing version published by another commercial legal publisher but containing parallel citations) to allow those who read their pleadings and other briefs to find the cases quickly and easily.

As of January 2019^{As of January 2019[update], there are:}

As of March 2012^[update], the U.S. Reports have published a total of 30,161 Supreme Court opinions, covering the decisions handed down from February 1790 to March 2012.^{[citation needed]} This figure does not reflect the number of cases the Court has taken up, as several cases can be addressed by a single opinion (see, for example, Parents v. Seattle, where Meredith v. Jefferson County Board of Education was also decided in the same opinion; by a similar logic, Miranda v. Arizona actually decided not only Miranda but also three other cases: Vignera v. New York, Westover v. United States, and California v. Stewart). A more unusual example is The Telephone Cases, which are a single set of interlinked opinions that take up the entire 126th volume of the U.S. Reports.

Opinions are also collected and published in two unofficial, parallel reporters: Supreme Court Reporter, published by West (now a part of Thomson Reuters), and United States Supreme Court Reports, Lawyers' Edition (simply known as Lawyers' Edition), published by Supreme Court Reporter, published by West (now a part of Thomson Reuters), and United States Supreme Court Reports, Lawyers' Edition (simply known as Lawyers' Edition), published by LexisNexis. In court documents, legal periodicals and other legal media, case citations generally contain cites from each of the three reporters; for example, citation to Citizens United v. Federal Election Commission is presented as Citizens United v. Federal Election Com'n, 585 U.S. 50, 130 S. Ct. 876, 175 L. Ed. 2d 753 (2010), with "S. Ct." representing the Supreme Court Reporter, and "L. Ed." representing the Lawyers' Edition.^[185][186]

Lawyers use an abbreviated format to cite cases, in the form "vol U.S. page, pin (year)", where vol is the volume number, page is the page number on which the opinion begins, and year is the year in which the case was decided. Optionally, pin is used to "pinpoint" to a specific page number within the opinion. For instance, the citation for Roe v. Wade is 410 U.S. 113 (1973), which means the case was decided in 1973 and appears on page 113 of volume 410 of U.S. Reports. For opinions or orders that have not yet been published in the preliminary print, the volume and page numbers may be replaced with "___".

Institutional powers and constraints

The Federal court system and the judicial authority to interpret the Constitution received little attention in the debates over the drafting and ratification of the Constitution. The power of judicial review, in fact, is nowhere mentioned in it. Over the ensuing years, the question of whether the power of judicial review was even intended by the drafters of the Constitution was quickly frustrated by the lack of evidence bearing on the question either way.^[187] Nevertheless, the power of judiciary to overturn laws and executive actions it determines are unlawful or unconstitutional is a well-established precedent. Many of the Founding Fathers accepted the notion of judicial review; in Federalist No. 78, Alexander Hamilton wrote: "A Constitution is, in fact, and must be regarded by the judges, as a fundamental law. It therefore belongs to them to ascertain its meaning, as well as the meaning of any particular act proceeding from the legislative body. If there should happen to be an irreconcilable variance between the two, that which has the superior obligation and validity ought, of course, to be preferred; or, in other words, the Constitution ought to be preferred to the statute."

The Supreme Court firmly established its power to declare laws unconstitutional in Marbury v. Madison (1803), consummating the American system of checks and balances. In explaining the power of judicial review, Chief Justice John Marshall stated that the authority to interpret the law was the particular province of the courts, part of the duty of the judicial department to say what the law is. His contention was not that the Court had privileged insight into constitutional requirements, but that it was the constitutional duty of the judiciary, as well as the other branches of government, to read and obey the dictates of the Constitution.^[187]

Since the founding of the republic, there has been a tension between the practice of judicial review and the democratic ideals of egalitarianism, self-government, self-determination and freedom of conscience. At one pole are those who view the Federal Judiciary and especially the Supreme Court as being "the most separated and least checked of all branches of government".^[188] Indeed, federal judges and justices on the Supreme Court are not required to stand for election by virtue of their tenure "during good behavior", and their pay may "not be diminished" while they hold their position (Section 1 of Article Three). Though subject to the process of impeachment, only one Justice has ever been impeached and no Supreme Court Justice has been removed from office. At the other pole are those who view the judiciary as the least dangerous branch, with little ability to resist the exhortations of the other branches of government.^[187]

The Supreme Court, it is noted, cannot directly enforce its rulings; instead, it relies on respect for the Constitution and for the law for adherence to its judgments. One notable instance of nonacquiescence came in 1832, when the state of Georgia ignored the Supreme Court's decision in Worcester v. Georgia. President Andrew Jackson, who sided with the Georgia courts, is supposed to have remarked, "John Marshall has made his decision; now let him enforce it!";^[189] however, this alleged quotation has been disputed.^{[citation needed]} Some state governments in the South also resisted the desegregation of public schools after the 1954 judgment Brown v. Board of Education. More recently, many feared that President Nixon would refuse to comply with the Court's order in United States v. Nixon (1974) to surrender the Watergate tapes.^{[190][citation needed]} Nixon, however, ultimately complied with the Supreme Court's ruling.

Supreme Court decisions can be (and have been) purposefully overturned by constitutional amendment, which has happened on five occasions:

When the Court rules on matters involving the interpretation of laws rather than of the Constitution, simple legislative action can reverse the decisions (for example, in 2009 Congress passed the Lilly Ledbetter act, superseding the limitations given in Ledbetter v. Goodyear Tire & Rubber Co. in 2007). Also, the Supreme Court is not immune from political and institutional consideration: lower federal courts and state courts sometimes resist doctrinal innovations, as do law enforcement officials.^[191]

In addition, the other two branches can restrain the Court through other mechanisms. Congress can increase the number of justices, giving the President power to influence future decisions by appointments (as in Roosevelt's Court Packing Plan discussed above). Congress can pass legislation that restricts the jurisdiction of the Supreme Court and other federal courts over certain topics and cases: this is suggested by language in Section 2 of Article Three, where the appellate jurisdiction is granted "with such Exceptions, and under such Regulations as the Congress shall make." The Court sanctioned such congressional action in the Reconstruction case ex parte McCardle (1869), though it rejected Congress' power to dictate how particular cases must be decided in United States v. Klein (1871).

On the other hand, through its power of judicial review, the Supreme Court has defined the scope and nature of the powers and separation between the legislative and executive branches of the federal government; for example, in United State

On the other hand, through its power of judicial review, the Supreme Court has defined the scope and nature of the powers and separation between the legislative and executive branches of the federal government; for example, in United States v. Curtiss-Wright Export Corp. (1936), Dames & Moore v. Regan (1981), and notably in Goldwater v. Carter (1979), (where it effectively gave the Presidency the power to terminate ratified treaties without the consent of Congress). The Court's decisions can also impose limitations on the scope of Executive authority, as in Humphrey's Executor v. United States (1935), the Steel Seizure Case (1952), and United States v. Nixon (1974).

Each Supreme Court justice hires several law Clerks to review petitions for writ of certiorari, research them, prepare bench memorandums, and draft opinions. Associate justices are allowed four clerks. The chief justice is allowed five clerks, but Chief Justice Rehnquist hired only three per year, and Chief Justice Roberts usually hires only four.^[192] Generally, law clerks serve a term of one to two years.

The first law clerk was hired by Associate Justice Horace Gray in 1882.^[192][193] Horace Gray in 1882.^[192][193] Oliver Wendell Holmes, Jr. and Louis Brandeis were the first Supreme Court justices to use recent law school graduates as clerks, rather than hiring a "stenographer-secretary".^[194] Most law clerks are recent law school graduates.

The first female clerk was Lucile Lomen, hired in 1944 by Justice William O. Douglas.^[192] The first African-American, William T. Coleman, Jr., was hired in 1948 by Justice Felix Frankfurter.^[192] A disproportionately large number of law clerks have obtained law degrees from elite law schools, especially Harvard, Yale, the University of Chicago, Columbia, and Stanford. From 1882 to 1940, 62% of law clerks were graduates of Harvard Law School.^[192] Those chosen to be Supreme Court law clerks usually have graduated in the top of their law school class and were often an editor of the law review or a member of the moot court board. By the mid-1970s, clerking previously for a judge in a federal court of appeals had also become a prerequisite to clerking for a Supreme Court justice.^[195]

Nine Supreme Court justices previously clerked for other justices: Byron White for Frederick M. Vinson, John Paul Stevens for Wiley Rutledge, William Rehnquist for Robert H. Jackson, Stephen Breyer for Arthur Goldberg, John Roberts for William Rehnquist, Elena Kagan for Thurgood Marshall, Neil Gorsuch for both Byron White and Anthony Kennedy, Brett Kavanaugh also for Kennedy, and Amy Coney Barrett for Antonin Scalia. Justices Gorsuch and Kavanaugh served under Kennedy during the same term. Gorsuch is the first justice to serve alongside a justice for whom he or she clerked, serving alongside Kennedy from April 2017 through Kennedy's retirement in 2018. With the confirmation of Justice Kavanaugh, for the first time a majority of the Supreme Court was composed of former Supreme Court law clerks (Roberts, Breyer, Kagan, Gorsuch and Kavanaugh, now joined by Barrett).

Several current Supreme Court justices have also clerked in the federal courts of appeals: John Roberts for Judge Henry Friendly of the United States Court of Appeals for the Second Circuit, Justice Samuel Alito for Judge Leonard I. Garth of the United States Court of Appeals for the Third Circuit, Elena Kagan for Judge Abner J. Mikva of the United States Court of Appeals for the District of Columbia Circuit, Neil Gorsuch for Judge David B. Sentelle of the United States Court of Appeals for the District of Columbia, Brett Kavanaugh for Judge Walter Stapleton of the United States Court of Appeals for the Third Circuit and Judge Alex Kozinski of the United States Court of Appeals for the Ninth Circuit, and Amy Coney Barrett for Judge Laurence Silberman of the U.S. Court of Appeals for the D.C. Circuit.

Clerks hired by each of the justices of the Supreme Court are often given considerable leeway in the opinions they draft. "Supreme Court clerkship appeared to be a nonpartisan institution from the 1940s into the 1980s," according to a study published in 2009 by the law review of Vanderbilt University Law School.^[196][197] "As law has moved closer to mere politics, political affiliations have naturally and predictably become proxies for the different political agendas that have been pressed in and through the courts," former federal court of appeals judge J. Michael Luttig said.^[196] David J. Garrow, professor of history at the University of Cambridge, stated that the Court had thus begun to mirror the political branches of government. "We are getting a composition of the clerk workforce that is getting to be like the House of Representatives," Professor Garrow said. "Each side is putting forward only ideological purists."^[196]

According to the Vanderbilt Law Review study, this politicized hiring trend reinforces the imp

According to the Vanderbilt Law Review study, this politicized hiring trend reinforces the impression that the Supreme Court is "a superlegislature responding to ideological arguments rather than a legal institution responding to concerns grounded in the rule of law".^[196] A poll conducted in June 2012 by The New York Times and CBS News showed just 44% of Americans approve of the job the Supreme Court is doing. Three-quarters said justices' decisions are sometimes influenced by their political or personal views.^[198]

The Supreme Court has been the object of criticisms on a range of issues. Among them:
