Chapter 12 — The Federal Courts: Judicial Review, Interpretation, and the Myth of Neutral Judging

"Judges are like umpires. Umpires don't make the rules; they apply them. The role of an umpire and a judge is critical. They make sure everybody plays by the rules. But it is a limited role. Nobody ever went to a ball game to see the umpire." — John G. Roberts Jr., Senate Judiciary Committee opening statement, September 12, 2005

"There is no position which depends on clearer principles, than that every act of a delegated authority, contrary to the tenor of the commission under which it is exercised, is void." — Alexander Hamilton, Federalist No. 78 (1788)

"It is emphatically the province and duty of the judicial department to say what the law is." — Chief Justice John Marshall, Marbury v. Madison, 5 U.S. (1 Cranch) 137, 177 (1803)

12.1 The branch the Founders worried about least

When Alexander Hamilton sat down to defend the proposed federal judiciary in Federalist No. 78, he had a problem. The Anti-Federalists — the loose coalition of pamphleteers and politicians who opposed the Constitution — had attacked the new courts as a likely engine of tyranny. They feared judges who could not be removed by elections, who would interpret a vague Constitution however they pleased, and who would gradually consolidate power in a tribunal accountable to nobody. Hamilton's defense, in one of the most quoted lines in American constitutional thought, was reassurance disguised as theory:

"The judiciary is beyond comparison the weakest of the three departments of power… it has no influence over either the sword or the purse… it can take no active resolution whatever. It may truly be said to have neither FORCE nor WILL, but merely judgment."¹

The argument was that the judiciary, having no army to enforce its rulings and no money to spend on its preferences, would always depend on the elected branches to make its decisions stick. It would therefore be the branch least likely to threaten liberty. Hamilton thought the Anti-Federalists had it exactly backwards. The real danger was an overpowered Congress, not a too-powerful court.

Two and a half centuries later, that prediction looks at best half right. The federal judiciary still has neither sword nor purse. Federal judges still cannot raise armies, levy taxes, or arrest violators of their orders without help from the executive branch. And yet today's federal courts — the 94 district courts, the 13 circuit courts of appeals, and the Supreme Court — exercise an authority over American life that Hamilton would have found startling. They have struck down roughly 180 acts of Congress and over 1,500 state laws.² They have ordered school desegregation in the South, decided presidential elections, redrawn legislative maps, declared and unmade rights to abortion, defined the constitutional limits of the regulatory state, and rewritten substantial portions of the country's social order. They are at the center of the most contested political conflicts of our time.

This chapter is the foundational architecture of that judicial branch — the design Article III gives us, the doctrine of judicial review the courts have given themselves, the structure of the federal court system, the way federal judges are chosen, and the long-running argument over what judges actually do when they "interpret" a statute or a constitutional provision. Chapter 13 covers the lower federal courts in operational detail. Chapter 14 covers the Supreme Court specifically. This chapter sets the stage for both.

The chapter's central argument is honest and contested: the popular picture of the federal judge as a neutral umpire, applying clear law to determined facts, is empirically dubious. The data show clearly that federal judges' votes correlate with the political party of the president who appointed them, especially on contested questions. That correlation does not mean judges are partisans in robes. It means that interpretive choices have ideological valence — that the choices between textualism and purposivism, between originalism and living constitutionalism, between deferring to Congress and deferring to agencies, are not politically neutral. Judges work in good faith within their interpretive traditions, and those traditions tilt toward different outcomes on the questions that divide the country. We will examine both the empirical reality and the formalist response that legal craft is real and constraining. Both views have honest defenders.

By the end of the chapter you should be able to:

• State the constitutional basis for the federal judiciary in Article III, including the cases-and-controversies requirement and the doctrines of justiciability.
• Explain the doctrine of judicial review — its theoretical foundation in Federalist No. 78, its establishment in Marbury v. Madison, and its extension to state courts in Martin v. Hunter's Lessee and Cohens v. Virginia.
• Describe the three-tier structure of the federal judiciary, including specialized courts and the constitutional distinction between Article III courts and Article I tribunals.
• Walk through the federal judicial selection process — nomination, vetting, Senate Judiciary Committee, floor confirmation, the blue slip, the nuclear option — and explain how that process has changed since 2013.
• Steel-man both originalism and living constitutionalism as constitutional-interpretation traditions, and steel-man both textualism and purposivism as statutory-interpretation traditions.
• Explain the doctrine of stare decisis, the factors courts use to decide whether to overrule precedent, and the contested question of when overruling is principled and when it is political.
• Assess the empirical evidence that federal judges' votes correlate with their appointing president's party, and articulate the strongest formalist response to that evidence.

12.2 What Article III actually says

Article III is by far the shortest of the Constitution's first three articles. Where Article I (Congress) runs to ten sections and includes a long list of enumerated powers, and Article II (the presidency) covers four sections of executive authority, Article III is a sparse three sections occupying less than a single page in most printings of the Constitution. The Founders left an enormous amount unspecified.

Section 1 is the vesting clause: "The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish." Two things to notice. First, the Constitution itself creates only the Supreme Court. The lower federal courts — every district court, every circuit court — exist because Congress chose to create them under its Article III authority. Congress could, in principle, abolish all lower federal courts tomorrow. (It will not. But in principle, it could.) Second, "judicial Power" is not defined. The Founders left the substance of what judges do to history and practice.

Section 1 also contains the famous tenure-and-salary protections: federal judges "shall hold their Offices during good Behaviour" and "shall, at stated Times, receive for their Services, a Compensation, which shall not be diminished during their Continuance in Office." This is the constitutional foundation for what is colloquially called life tenure for federal judges. Strictly speaking, judges hold office "during good behavior," which means they can be removed by impeachment for high crimes and misdemeanors. In practice, only 15 federal judges have ever been impeached by the House, and only 8 of those convicted by the Senate.³ The "salary protection" is also significant: Congress cannot reduce a judge's pay during their service, which prevents the elected branches from coercing judges through their wallets.

Section 2 is the scope of judicial power. It enumerates the kinds of "Cases" and "Controversies" the federal courts may hear:

• Cases arising under the Constitution, federal statutes, or treaties (the basis for federal-question jurisdiction).
• Cases affecting ambassadors and other foreign officials.
• Cases of admiralty and maritime jurisdiction.
• Controversies in which the United States is a party.
• Controversies between two or more states.
• Controversies between a state and citizens of another state (modified by the Eleventh Amendment).
• Controversies between citizens of different states (the basis for diversity jurisdiction).

Section 2 also distinguishes between the Supreme Court's original jurisdiction (cases the Court hears first, without lower-court review) and its appellate jurisdiction (cases that come up to the Court from lower courts). The Court's original jurisdiction is narrow: it covers cases involving ambassadors, foreign officials, and disputes between states. The vast majority of the Court's docket is appellate.

Section 3 defines treason narrowly — the only crime defined in the Constitution itself — limits who may be punished for it, and forbids "corruption of blood" (the old English practice of disinheriting a traitor's family). This section will not detain us; it has been litigated rarely.

Notice what Article III does not say. It does not specify how many justices sit on the Supreme Court. It does not establish the lower federal courts. It does not describe the writ of certiorari, the process for reviewing state court decisions, the rules of standing, the doctrine of justiciability, or — most consequentially — the power to declare acts of Congress unconstitutional. Almost everything we associate with the modern federal judiciary is either statutory (Congress filled in the framework with the Judiciary Act of 1789 and many subsequent statutes) or judicially developed (the courts created the doctrines themselves through their decisions over time).

This is one of the structural facts that makes the federal judiciary distinctive. The institution is, to a significant degree, what its members have made of it.

12.3 The cases-and-controversies requirement

The phrase "Cases" and "Controversies" in Article III, Section 2 has been read by the Supreme Court to impose serious limits on what federal courts may do. They are not, in this reading, free-roving constitutional advisors. They decide actual disputes between parties with real stakes. The collection of doctrines that operationalize this requirement is called justiciability.

Standing. A plaintiff has constitutional standing to sue in federal court only if they can show three things: (1) an injury in fact that is concrete, particularized, and actual or imminent; (2) a causal connection between the injury and the defendant's conduct; and (3) a likelihood that the injury can be redressed by the relief the court could provide. The leading modern case is Lujan v. Defenders of Wildlife (1992), in which Justice Antonin Scalia spelled out this three-part test in close to the form the Court still uses.⁴ Standing has become one of the most consequential doctrines in modern federal practice. Cases that the public might assume are clear constitutional questions get dismissed because no plaintiff has standing to bring them.

Ripeness. A case must be ready for judicial decision. A claim that depends on events that may or may not happen is not ripe. The federal courts will not, for example, hear a constitutional challenge to a statute that has not yet been enforced and may never be, where the threat of enforcement is too speculative.

Mootness. A case that was once a live dispute but is no longer one — because the parties have settled, the law has been repealed, or the underlying conduct has ended — is moot, and federal courts will dismiss it. There are exceptions: cases "capable of repetition yet evading review" (a doctrine famously applied in Roe v. Wade because pregnancy normally ends before litigation does), voluntary cessation that does not eliminate the possibility of recurrence, and class actions where the named plaintiff's claim becomes moot but the class's does not.

Political question. Some constitutional questions, the Court has held, are committed by the Constitution itself to the political branches and are therefore not appropriate for judicial resolution. The classic statement is Baker v. Carr (1962), which set out six factors for identifying a non-justiciable political question.⁵ Foreign affairs disputes, impeachment procedures (Nixon v. United States, 1993, regarding the impeachment of Judge Walter Nixon, not President Richard Nixon), and partisan-gerrymandering claims (Rucho v. Common Cause, 2019) have all been held non-justiciable on political-question grounds. Race-based gerrymandering claims, by contrast, remain justiciable.

These doctrines do real work. They keep federal courts focused on concrete disputes. They also operate, as critics across the spectrum note, as gatekeeping devices: a court that wants to avoid deciding a politically uncomfortable question can find that the plaintiff lacks standing or that the matter is a political question. Whether the doctrines have been applied consistently is contested.

12.4 Judicial review: the power not in the Constitution

The single most important power of the federal judiciary — the power to declare acts of Congress, of state legislatures, and of the executive branch unconstitutional — is not mentioned in the Constitution. Article III speaks of "judicial Power" without defining it. The Constitution's supremacy clause (Article VI) declares that the Constitution and federal laws made under it are the supreme law of the land, and that judges in every state are bound by it — but the supremacy clause does not say that federal courts may strike down legislation. The doctrine that gives the courts this authority — judicial review — was established by the Supreme Court itself, in two acts of judicial assertion that took the better part of two decades.

Hamilton's argument in Federalist 78

The intellectual foundation was laid before the Constitution was ratified. In Federalist No. 78, Hamilton argued that judicial review followed naturally from the structure of a written constitution. If the Constitution is law, and if a statute conflicts with the Constitution, then a court bound to apply law must follow the Constitution rather than the statute. To do otherwise, Hamilton wrote, would be to allow the legislature to be "the constitutional judges of their own powers, and that the construction they put upon them is conclusive upon the other departments." That, Hamilton argued, would defeat the entire point of a written constitution that limits the legislature.

Hamilton's argument is elegant but not airtight. Critics in the founding era and since have pointed out that nothing in the text or structure of the Constitution clearly assigns the duty of constitutional enforcement to the judiciary in particular. Why not let each branch interpret the Constitution for its own purposes — Congress when it legislates, the president when it administers, the courts when it adjudicates? This is the position called departmentalism, and it had serious advocates in the founding generation, including Thomas Jefferson and James Madison at various points. Even Andrew Jackson, decades later, took something like this position when he reportedly refused to enforce Worcester v. Georgia in the Cherokee Removal context: "John Marshall has made his decision; now let him enforce it."

Hamilton won the historical argument. But the argument was won not by his pen but by the Marshall Court's willingness to act on it.

Marbury v. Madison (1803)

The case that established judicial review of acts of Congress, Marbury v. Madison, is the subject of Case Study 1 of this chapter, and we will treat it more fully there. The compressed version: in the chaotic transition from John Adams's Federalist administration to Thomas Jefferson's Democratic-Republican administration (1801), Adams attempted to fill many federal judgeships at the last minute — the famous "midnight judges." William Marbury was one of those would-be appointees. His commission had been signed but not delivered when Jefferson took office. Jefferson's secretary of state, James Madison, refused to deliver the commission, and Marbury sued in the Supreme Court for a writ of mandamus to compel delivery.

Chief Justice John Marshall's opinion is one of the great works of strategic legal architecture in American history. Marshall agreed that Marbury had a right to the commission. He agreed that there should be a remedy. But — here is the maneuver — Marshall held that the Supreme Court could not issue the writ of mandamus, because the statute purporting to give the Court that power (Section 13 of the Judiciary Act of 1789) had improperly expanded the Court's original jurisdiction beyond what Article III allowed. Section 13, in Marshall's reading, was unconstitutional. The Court therefore could not act.

The genius of the move is that Marshall established the power of judicial review — the power to declare a federal statute unconstitutional — in a case where the exercise of judicial review actually limited the Court's own authority. The Jefferson administration had no occasion to defy the ruling, because the ruling went in their favor on the immediate question. But in announcing that the Court would not enforce an unconstitutional act of Congress, Marshall established a precedent that the Court has cited ever since.

The famous passage:

"It is emphatically the province and duty of the judicial department to say what the law is. Those who apply the rule to particular cases, must of necessity expound and interpret that rule. If two laws conflict with each other, the courts must decide on the operation of each. So if a law be in opposition to the constitution; if both the law and the constitution apply to a particular case, so that the court must either decide that case conformably to the law, disregarding the constitution; or conformably to the constitution, disregarding the law; the court must determine which of these conflicting rules governs the case. This is of the very essence of judicial duty."

For a thorough treatment of the case's political and legal architecture, see Case Study 1.

Extending review to the states: Martin v. Hunter's Lessee and Cohens v. Virginia

Marbury established federal judicial review of acts of Congress. It did not establish federal judicial review of state court decisions. That came in two cases — Martin v. Hunter's Lessee (1816) and Cohens v. Virginia (1821) — and was at least as politically consequential.

Martin v. Hunter's Lessee arose from a dispute over land in Virginia that had been confiscated from a British loyalist during the Revolution. The Virginia Court of Appeals had ruled in favor of the state's confiscation; the U.S. Supreme Court reversed. The Virginia court then refused to obey the Supreme Court's mandate, asserting that the state's high court was the final word on questions of state law within the state. Justice Joseph Story, writing for the Supreme Court in 1816, emphatically rejected this. Section 25 of the Judiciary Act of 1789, Story held, validly empowered the Supreme Court to review state court decisions on questions of federal law. Without such authority, federal law could mean different things in different states, and the Constitution's promise of uniform federal supremacy would be empty.

Cohens v. Virginia, five years later, reinforced the same principle in a different procedural posture. The Cohens brothers had been convicted in Virginia state court of selling lottery tickets in violation of state law; they argued that federal law authorized the lottery and preempted the state prohibition. Virginia argued that the Supreme Court had no power to review a state criminal conviction. Marshall, again writing for the Court, again rejected the argument: when state courts decide questions of federal law, federal courts have appellate jurisdiction to ensure uniform interpretation.

These cases — Marbury, Martin, Cohens — together established the modern doctrine of judicial review. The federal courts can review acts of Congress for constitutionality. They can review state laws for conformity to federal law. They can review state court decisions on federal questions. These three doctrines, taken together, made the federal judiciary an active participant in defining the limits of every other actor in the constitutional system.

How often do the federal courts strike laws down?

A common impression — fed by media coverage of the most charged Supreme Court terms — is that federal courts are constantly striking laws down. The actual rate is quite a bit lower. Across the entire 230-plus-year history of the federal judiciary, the Supreme Court has invalidated roughly 180 acts of Congress in whole or in part.⁶ That averages out to fewer than one per year. The pace has accelerated in modern terms — the Roberts Court (2005–present) has struck down federal statutes at a higher rate than several earlier Courts — but even now the absolute number is small relative to the volume of federal legislation.

The number for state and local laws is much higher: well over 1,500 state and local enactments have been struck down by the federal courts over the same period.⁷ This asymmetry reflects two things. First, there are vastly more state and local laws than federal ones — every legislature in every state plus thousands of municipalities and counties. Second, the structure of constitutional federalism makes states subject to constraints (the Bill of Rights as incorporated through the Fourteenth Amendment, the Commerce Clause's "dormant" restrictions on state regulation of interstate commerce, the Equal Protection Clause) that have generated extensive case law about state power.

Whether 180 over 230 years is a lot or a little depends on what you compare it to. Compared to the volume of federal legislation, it is small. Compared to other countries' constitutional courts, the United States Supreme Court has historically been moderately active, more aggressive than the courts of, say, the United Kingdom (which until recently had no power of judicial review at all) but less aggressive than the German Federal Constitutional Court (which strikes down legislation more frequently). The empirical literature here is rich and contested; what is clear is that the United States is somewhere in the middle of comparable democracies in the active use of judicial review.

12.5 The federal court structure

The modern federal judiciary is a three-tier hierarchy with several specialized courts attached. The structure is mostly the product of statute, not Constitution; Congress has created and reorganized the lower federal courts repeatedly over more than two centuries.

District courts. At the trial level, the United States is divided into 94 federal judicial districts, each with its own district court.⁸ Most states have a single district (Wyoming, Utah, Massachusetts), but several states have multiple districts (California has four, Texas four, New York four, and so on). Each district has at least one judgeship; larger districts have many. Across the system, there are about 670 authorized district court judgeships, plus about 540 magistrate judges who handle a substantial fraction of the workload (more on magistrates below).

District courts are general-jurisdiction federal trial courts. They hear federal criminal prosecutions, civil cases arising under federal statutes, constitutional challenges, diversity-jurisdiction cases (where the parties are from different states and the amount in controversy exceeds $75,000), and a long list of specific federal causes of action. The district court is where the actual fact-finding happens — witnesses testify, juries deliberate, evidence gets admitted or excluded.

Circuit courts of appeals. The country is divided into 13 federal judicial circuits.⁹ Eleven of the circuits are geographic, numbered 1 through 11; together they cover all 50 states, the District of Columbia, and the territories. The First Circuit, for example, includes Maine, Massachusetts, New Hampshire, Rhode Island, and Puerto Rico. The Ninth Circuit, the largest, includes California, Oregon, Washington, Arizona, Nevada, Idaho, Montana, Alaska, Hawaii, Guam, and the Northern Mariana Islands. The District of Columbia Circuit is its own circuit, with jurisdiction primarily over federal-government and administrative-agency cases (it is sometimes called the "second-most-important court in the country" for this reason). The Federal Circuit hears specialized cases — patents, certain federal claims, and appeals from specialized courts.

The 13 circuits collectively have about 180 authorized circuit judgeships. Circuit court cases are normally heard by three-judge panels. In rare cases of special importance, the full circuit may hear the case en banc (all active judges of the circuit sitting together). Circuit courts are appellate; they review the decisions of district courts, and in administrative cases they review the decisions of federal agencies. They do not retry the facts; they review for legal error.

Supreme Court. At the apex sits the Supreme Court of the United States, with 9 justices. The number of justices is set by statute (the Judiciary Act of 1869), not by the Constitution. The Court has fluctuated in size from 6 justices originally (Judiciary Act of 1789) to as many as 10 (briefly in the 1860s). The number of seats has been a recurring point of political fight; the proposals from the 2020–22 period to expand the Court (often called "court packing" by opponents and "court expansion" by supporters) reflect the long history of treating Court size as a political question. President Franklin Roosevelt's 1937 plan to add up to six justices to a Supreme Court he considered hostile to the New Deal was decisively rejected by his own Democratic Senate. Whether a similar proposal could pass today is contested; we will revisit court reform in Chapter 38.

The Supreme Court hears a small fraction of the cases brought to it. It receives about 7,000–8,000 petitions for certiorari each term and grants full review to about 60–80.¹⁰ The Court therefore disposes of roughly 99 percent of petitions without merits review. Chapter 14 covers the Supreme Court's processes — cert grants, oral argument, opinion drafting, the role of clerks — in operational detail.

Specialized courts. Several federal courts handle specialized subject matter:

• The U.S. Court of Federal Claims hears monetary claims against the United States.
• The U.S. Tax Court hears disputes over federal tax assessments.
• The U.S. Court of International Trade hears customs and trade cases.
• The Foreign Intelligence Surveillance Court (FISA Court) reviews surveillance applications under the Foreign Intelligence Surveillance Act of 1978.
• Military courts (courts-martial under the Uniform Code of Military Justice) have jurisdiction over service members.
• Bankruptcy courts are units of the district courts and handle bankruptcy proceedings.

Some of these are Article III courts (the Court of International Trade, for example), and some are not. That distinction — Article III versus Article I — matters constitutionally.

12.6 Article III courts vs. Article I tribunals

Not every body that calls itself a "court" in the federal system is an Article III court. Some — including bankruptcy courts, the Tax Court, the Court of Federal Claims, military courts, and various administrative tribunals — are Article I tribunals, created by Congress under its various Article I powers (the bankruptcy power, the taxing power, the power to govern the armed forces, and so on). The constitutional distinction matters.

Judges on Article III courts have life tenure during good behavior and salary protection. They cannot be removed except by impeachment. Their independence from the elected branches is constitutionally guaranteed.

Judges on Article I tribunals do not have these protections. Bankruptcy judges, for example, serve 14-year renewable terms, appointed by the courts of appeals. Tax Court judges serve 15-year terms, appointed by the president. They can be reappointed, or not. They can have their pay adjusted. They are, in important ways, less independent than Article III judges.

This raises a constitutional question: when does Article III require that a particular kind of case be decided by an Article III court? The Supreme Court has wrestled with this question for two centuries. The general principle: matters of "private right" — disputes between private parties about traditional common-law claims — generally must be heard by Article III courts. Matters of "public right" — disputes between private parties and the government over benefits, taxes, regulatory matters, and the like — may be heard by Article I tribunals.

The line is genuinely fuzzy, and the modern Court has sharpened it in recent cases. Stern v. Marshall (2011) held that bankruptcy courts could not constitutionally decide certain state-law counterclaims — even within bankruptcy proceedings — because doing so would intrude on Article III's commitment of the "judicial Power" to courts whose judges have life tenure and salary protection.¹¹ Wellness International Network v. Sharif (2015) held that parties could consent to bankruptcy-court adjudication of such claims, softening the Stern rule somewhat.¹² These cases matter for thousands of bankruptcy proceedings every year and for the broader question of how much of the federal judicial workload Congress can delegate to non-Article-III adjudicators.

The Article III/Article I distinction is more than a constitutional curiosity. The federal regulatory state runs on administrative adjudication — by administrative law judges within agencies who are not Article III judges. Securities and Exchange Commission enforcement cases, Social Security disability hearings, immigration removal proceedings, and many more are decided in the first instance by adjudicators who lack Article III protections. Whether and when this is constitutional is a live question. The Roberts Court has begun pulling back on agency adjudication in cases like SEC v. Jarkesy (2024), which held that the Seventh Amendment's right to a jury trial requires that certain SEC enforcement actions involving civil penalties be tried in federal court rather than before agency administrative law judges. Chapter 14 returns to this question in the context of the major-questions doctrine and the broader administrative-law revolution under way in the Roberts Court.

12.7 Magistrates and bankruptcy judges: the workforce

If the public picture of federal judging is the Article III judge in the marble courtroom, the operational reality is that an enormous fraction of federal judicial work is done by magistrate judges and bankruptcy judges — about 540 magistrates and 350 bankruptcy judges nationwide, all of them Article I officers.

Magistrate judges are appointed by the district courts to eight-year renewable terms. They handle pretrial matters in civil and criminal cases (initial appearances, detention hearings, search-warrant applications, pretrial conferences, discovery disputes), conduct settlement conferences, hear misdemeanors, and — with the consent of the parties — preside over civil trials. In many districts, the magistrate workload is what keeps the docket moving. When you read a published district court opinion, you are seeing the visible part of the iceberg; magistrate judges are doing the work that never reaches the published-opinion stage.

Bankruptcy judges are appointed by the courts of appeals to 14-year renewable terms. They handle the entire universe of bankruptcy cases — Chapter 7 liquidations, Chapter 11 reorganizations, Chapter 13 individual repayment plans. American bankruptcy law is voluminous, technical, and consequential; bankruptcy judges decide cases that determine whether companies survive, whether creditors get paid, and whether individuals can discharge debts. The volume is staggering — about 400,000 bankruptcy filings per year as of the mid-2020s.¹³

Both magistrate and bankruptcy judges are Article I officers. They are not constitutionally guaranteed independence the way Article III judges are. But they are part of the federal judicial workforce, and any honest description of how the federal courts operate has to include them.

12.8 Selecting federal judges: the process

Article II, Section 2, Clause 2 provides that the president shall nominate, and "by and with the Advice and Consent of the Senate, shall appoint… Judges of the supreme Court." The same clause, by judicial gloss and statutory practice, applies to lower federal judges. The process has six rough stages.

Identification. When a vacancy opens (because a judge dies, retires, takes "senior status," or — more rarely — resigns), the White House counsel's office and the Department of Justice's Office of Legal Policy generate a list of candidates. Different administrations have different sources. Republican administrations since the Reagan era have drawn heavily from the Federalist Society, a network of conservative and libertarian lawyers founded in 1982 that has become the principal pipeline for conservative judicial appointments. Democratic administrations have drawn from a more diffuse set of sources, including the American Constitution Society (a progressive counterpart to the Federalist Society, founded in 2001), academic networks, civil-rights organizations, and the personal networks of administration lawyers.

Vetting. Candidates are subjected to extensive background investigation. The FBI conducts a full-field background check. The candidate fills out a long Senate Judiciary Committee questionnaire detailing their professional history, judicial philosophy, financial holdings, and writings. The American Bar Association rates the candidate as "well qualified," "qualified," or "not qualified" — though some recent Republican administrations have de-emphasized or bypassed the ABA rating, arguing that the ABA's evaluations have leaned Democratic.¹⁴ The candidate's published writings, speeches, and judicial opinions (if any) are scrutinized for ideological signals.

Nomination. When the president formally nominates a candidate, the nomination is referred to the Senate Judiciary Committee for hearings. The committee chair sets the hearing schedule and controls the committee process. Whether the nomination moves at all depends substantially on the chair's choices.

Senatorial courtesy and the blue slip. For district court nominations specifically (and historically for some circuit court nominations), the blue slip tradition gives home-state senators a powerful voice. The Judiciary Committee chair sends a literal blue slip of paper to each home-state senator asking whether they support the nominee. Historically, a negative blue slip (or a withheld blue slip) from a home-state senator could effectively kill the nomination at the committee stage. This practice has weakened over time. Different chairs have applied it differently. Senator Patrick Leahy (D-VT) honored blue slips strictly during his Judiciary chairmanship; Senator Chuck Grassley (R-IA) honored them for district courts but not always for circuit courts; Senator Lindsey Graham (R-SC) and his successors have applied the practice with varying strictness. The current state of the blue slip is contested and depends on whichever party controls the Senate. Senatorial courtesy is the broader, less formal practice in which home-state senators expect to be consulted on district court nominations; it has been around since the Washington administration.

Hearings and committee vote. The Judiciary Committee holds a public hearing at which the nominee testifies and answers questions. For lower-court nominees, the hearings are usually short and routine. For Supreme Court nominees, the hearings have become major political events, watched live by tens of millions of viewers, with sustained questioning over multiple days. The committee then votes on whether to report the nomination favorably to the floor.

Floor action. The Senate as a whole votes on confirmation. A simple majority is required to confirm. Until 2013, there was an effective 60-vote threshold for cloture (cutting off debate) on lower-court nominations, meaning a determined minority of 41 senators could block a nominee. In 2013, the Democratic Senate majority, frustrated by what they saw as unprecedented Republican obstruction, used the nuclear option — a parliamentary maneuver that changed the cloture threshold for executive-branch and lower-court nominations from 60 votes to a simple majority. In 2017, the Republican Senate majority extended the same change to Supreme Court nominations in order to confirm Justice Neil Gorsuch over a Democratic filibuster. Both changes were enacted by majority vote — the original Senate rule that 67 votes were required to change Senate rules was itself overridden by majority vote, the parliamentary equivalent of pulling oneself up by one's bootstraps.

The consequence: federal judges can now be confirmed by simple majority vote. The 60-vote threshold for legislation remains, but for nominations, the chamber has effectively abandoned the supermajority requirement.

Confirmation patterns and trends

The confirmation process has become slower and more partisan over the past two decades. Several measurable trends:

Time-to-confirm. Median days from nomination to confirmation has grown substantially. In the 1980s and earlier, lower-court nominees were typically confirmed within 60–90 days. By the 2010s, the median had stretched to 200–300 days. Both parties have contributed; the trend is not solely the work of one side.

Margin of confirmation. Once-routine confirmations now produce close partisan votes. Justice Sandra Day O'Connor was confirmed 99–0 in 1981. Justice Antonin Scalia was confirmed 98–0 in 1986. Justice Ruth Bader Ginsburg was confirmed 96–3 in 1993. Compare this to recent confirmations: Justice Brett Kavanaugh, 50–48 in 2018; Justice Amy Coney Barrett, 52–48 in 2020; Justice Ketanji Brown Jackson, 53–47 in 2022. The shift is real and is bipartisan; both parties' nominees now face nearly party-line opposition.

Failed and withdrawn nominations. A small but growing number of nominations fail or are withdrawn. Justice Robert Bork's 1987 nomination was rejected 42–58 by the Senate after sustained ideological opposition. Justice Harriet Miers's 2005 nomination was withdrawn before a hearing in the face of conservative concerns about her qualifications. Garland's 2016 Supreme Court nomination by President Obama never received a hearing or a vote, because the Republican Senate majority under Mitch McConnell declined to consider it; the Garland nomination expired with the end of the 114th Congress in January 2017. The Garland episode is one of the most contested cases of constitutional hardball in modern Senate history, and we discuss it further in Chapter 14.

12.9 Who is a federal judge? Demographics and background

A purely formal description of who federal judges are tells only part of the story. The empirical demographic and professional profile of the federal judiciary is, itself, a site of contested political claim.

Race and gender. Federal judges have grown more diverse over time. As of the mid-2020s, about 35–40 percent of active federal judges are women, and about 25–30 percent are non-white. These figures reflect substantial change from the federal judiciary of the 1970s, which was about 95 percent male and about 95 percent white. Each presidential administration since Carter has emphasized diversity in different ways. Carter created the merit-selection commissions and substantially increased the number of women and minority judges. Reagan reduced the emphasis. Clinton increased it again. Both Obama and Biden made diversity an explicit priority. Trump's first-term appointments had high credentialed quality (almost all from elite law schools) but were demographically less diverse than Obama's; Biden's appointments were the most diverse cohort in federal judicial history by several measures. Trump's second-term appointments, ongoing as of 2026, are following a pattern more like the first term.¹⁵

Professional background. Here the picture is striking. Federal judges are drawn overwhelmingly from two professional backgrounds: former federal prosecutors (Department of Justice or U.S. Attorney's offices) and lawyers from large corporate law firms. The combined share of these two backgrounds, across the federal judiciary, is well over 70 percent. By contrast, lawyers from the public defender ranks, from criminal defense practice, from civil rights legal aid, from plaintiffs' employment law, and from labor unions are substantially underrepresented. Of the roughly 670 active district court judges as of recent counts, the number with substantial public-defender experience is in the low double digits.¹⁶

Whether this matters is contested. One view — held by many criminal-defense and civil-rights advocates — is that a judiciary drawn so heavily from the prosecutorial and corporate-defense bar will systematically tilt rulings on criminal procedure, on civil-rights enforcement, and on access-to-court doctrines. Empirical work has produced some support for this hypothesis, particularly on criminal-procedure questions; judges with prior public-defender experience appear to rule somewhat more favorably to defendants than judges without such experience, even controlling for appointing-president party.¹⁷

The other view is that professional background is a proxy for skill and experience that correlates with diversity of viewpoint less strongly than critics suppose. Many former prosecutors have served as defense counsel earlier in their careers; many corporate lawyers have done extensive pro bono civil-rights work. The legal professionalism that all federal judges share, this view holds, is more important than the specific firm or office they came from.

The Biden administration, more than any prior administration, made an explicit effort to nominate former public defenders, civil-rights lawyers, and labor lawyers — about 30 percent of Biden's appointments came from these backgrounds, more than triple the rate under any prior president. Whether that shift will translate into measurable doctrinal changes remains to be seen.

12.10 The myth of neutral judging

Now we come to the chapter's central argument. The popular picture of the federal judge is the Roberts umpire metaphor: a neutral arbiter who applies clear law to determined facts and renders a result that, ideally, any other competent judge applying the same law would reach. This picture is taught in civics class. It animates much of the public discourse about what judges should do. And the empirical evidence does not support it as a complete description of how federal judging actually works on the politically charged questions.

The empirical picture

Cass Sunstein and his collaborators have, over more than two decades, conducted some of the most systematic empirical work on judicial voting patterns. The findings are robust across many specifications and many areas of law:¹⁸

• On politically charged questions — including affirmative action, campaign finance, environmental regulation, employment discrimination, and First Amendment claims — federal judges' votes correlate substantially with the political party of the appointing president.
• The effect is stronger when judges sit with ideologically similar colleagues and weaker (a phenomenon Sunstein calls the "panel effect") when judges sit with colleagues of the opposite party — three-judge panels with mixed-party composition produce less ideologically polarized outcomes than panels with same-party composition.
• The effect varies by area of law. Statutory interpretation produces moderate ideological splits; constitutional cases produce larger ones. Cases turning on procedural or technical questions (whether to admit certain evidence, for example) produce smaller splits.
• The effect appears at every level of the federal judiciary — district court, circuit court, and Supreme Court — though it is largest at the Supreme Court.

Recent empirical work has confirmed and extended Sunstein's findings. Kevin Cope and Joshua Fischman, Adam Bonica, and others have produced ideal-point estimates of judicial ideology that map well onto the appointing-president variable.¹⁹ The Martin-Quinn scores for Supreme Court justices, derived from voting patterns, show clear ideological clusters that correspond to appointing-president party.²⁰

This is what is meant when scholars say judicial votes correlate with appointing-president party. They are not claiming that judges are partisans, that they take orders from political parties, or that they decide cases in bad faith. They are reporting a statistical regularity that is robust to many alternative explanations.

What this does and does not mean

It does not mean federal judges are corrupt. It does not mean they decide cases by checking how the Republican or Democratic Party would prefer they vote. It does not mean they are political operatives. The careful empirical literature is unanimous that the appointing-president effect is mediated through interpretive philosophy, not through direct political instruction.

It does mean that interpretive choices have ideological valence. When a judge chooses textualism over purposivism in statutory interpretation, that choice systematically produces certain kinds of outcomes more than others. When a judge chooses originalism over living constitutionalism in constitutional interpretation, that choice systematically produces certain kinds of outcomes more than others. The choices are not politically random. Within each interpretive tradition, judges work in good faith. But the tradition itself is doing political work.

A worked example: textualism in statutory interpretation tends to produce narrower readings of civil-rights statutes than purposivism does, because civil-rights statutes were typically written with broad remedial purposes that the literal text does not always fully capture. Bostock v. Clayton County (2020), in which Justice Neil Gorsuch wrote a textualist opinion holding that Title VII's prohibition on discrimination "because of sex" includes discrimination against gay and transgender employees, is sometimes cited as a counterexample — a textualist methodology producing what is conventionally read as a "liberal" outcome. The case is real, and important, and shows that the correlation is statistical, not deterministic. But on average, across many cases, textualism and originalism tilt toward conservative outcomes; purposivism and living constitutionalism tilt toward liberal ones. The tilt is the political valence of the interpretive choice.

Steel-manning the realist view

The legal-realist view holds that politics influences judging substantially and that the formalist denial of this is itself a political move. Realists point to the empirical evidence reviewed above. They point to the fact that confirmation battles are now nearly always partisan, suggesting that everyone — senators, presidents, advocates — understands that judging is political in fact even if it is not supposed to be in theory. They point to the existence of ideologically organized vetting infrastructures (the Federalist Society, the American Constitution Society) on both sides, which would not exist if judging were genuinely apolitical. They point to the predictability of how individual justices vote on contested issues, often years before those issues reach the Court.

The strongest version of the realist view is not "judges are partisans." It is "law underdetermines outcomes on the contested questions, and what fills the gap is judicial philosophy, which is itself politically inflected." This is a careful and defensible claim. Many sophisticated lawyers and legal scholars, across the spectrum, accept some version of it.

Steel-manning the formalist view

The formalist view does not deny the empirical patterns. It holds that legal craft is real and constraining, that judges who behave like partisans are recognizable as such and are widely criticized within the profession, and that the tradition of careful legal reasoning — reading statutes attentively, applying precedent honestly, distinguishing relevant from irrelevant facts — exerts a genuine discipline on judicial behavior even when it does not eliminate ideological influence.

The strongest version of the formalist view points to the many cases that defy the appointing-president prediction. Justice Scalia's textualist reading of the Confrontation Clause in Crawford v. Washington (2004) gave criminal defendants a substantial new right at the expense of prosecutors. Bostock (above). Chief Justice Roberts's vote to uphold the Affordable Care Act in NFIB v. Sebelius (2012). Justice Gorsuch's opinions on Native American sovereignty (McGirt v. Oklahoma, 2020) that aligned with traditionally liberal positions. Justice Kagan's votes against expansive readings of standing in environmental cases. Each of these was the result of the justice applying legal craft to the case in front of them, and the legal craft pulled in a direction the appointing-president variable would not have predicted.

Both views capture something true. The realist view captures the statistical regularity. The formalist view captures the within-tradition discipline that keeps law from being purely political. The honest description is that judicial decision-making is a hybrid: politically inflected at the macro level, but constrained at the micro level by the actual demands of legal craft.

The Roberts umpire metaphor is best understood as an aspiration — a description of what judges should strive for, not a description of what they always achieve. Whether we should expect the aspiration to be more closely approximated than it is, and what reforms (if any) might help, is a contested question that we will return to in Chapter 38.

12.11 Statutory interpretation: textualism vs. purposivism

When a federal court interprets a statute, it must choose among methodologies. The two leading traditions are textualism and purposivism.

Textualism holds that the meaning of a statute is the meaning of its text, as understood by an ordinary speaker of English at the time of enactment. The interpreter's job is to read the words carefully, apply the standard canons of construction (interpretive rules like expressio unius — the expression of one thing implies the exclusion of others — and the rule against absurdity), and reach the ordinary public meaning. Legislative history — committee reports, floor speeches, conference reports — is generally disfavored, on the ground that what Congress enacted was the text, not the surrounding commentary about the text. Justice Antonin Scalia, in collaboration with Bryan Garner in Reading Law: The Interpretation of Legal Texts (2012), produced the most systematic modern statement of textualism.²¹

Purposivism holds that the interpreter's job is to identify the purpose Congress was pursuing in enacting the statute and read the statutory text in light of that purpose. Where the text is ambiguous, purposivists turn to legislative history, statutory structure, and the broader policy goals the statute was designed to serve. The classic statement of purposivism is the Hart and Sacks legal-process school of the mid-twentieth century — Henry Hart and Albert Sacks's "Legal Process" materials at Harvard.²² Justices John Paul Stevens and Stephen Breyer were notable purposivist voices on the modern Court.

The current Supreme Court has trended strongly textualist. Justice Scalia drove much of this shift; Justice Gorsuch, Justice Kavanaugh, and Justice Barrett are all self-identified textualists. Justice Kagan, in her 2015 Harvard lecture, said memorably "we are all textualists now."²³ Whether her statement was accurate or aspirational is debated, but the direction of the Court's methodology is clear. The shift has practical consequences: judges who used to look first at legislative history now look first at dictionaries, corpus-linguistics evidence, and structural arguments from the surrounding text.

The textualism-purposivism divide produced striking disagreements in the Roberts Court era. King v. Burwell (2015), the Affordable Care Act case, turned on whether the phrase "exchange established by the State" included federal exchanges; Chief Justice Roberts, writing for the Court, used a purposivist approach (Congress's evident purpose was to make the exchanges work) to reach a result Justice Scalia in dissent attacked as "interpretive jiggery-pokery" inconsistent with textualist principles. Bostock v. Clayton County (2020) was the inverse — Justice Gorsuch's textualist majority opinion produced an outcome Justice Alito's textualist dissent attacked as inconsistent with how an ordinary speaker would have read the statute in 1964. The cases together show that methodology is not destiny: judges within both traditions can disagree, and judges within one tradition can produce outcomes that surprise their usual allies.

12.12 Constitutional interpretation: originalism, living constitutionalism, and the alternatives

Statutory interpretation is hard. Constitutional interpretation is harder, because the Constitution is older, sparer, and far less responsive to ordinary amendment than any statute. The American legal tradition has developed several methodological approaches to constitutional interpretation, each with sophisticated defenders.

Originalism holds that the Constitution should be interpreted according to the meaning it had at the time of its enactment. There are several internal disagreements within the originalist family:

• Original intent originalism focuses on what the framers and ratifiers of a particular provision actually intended. This is the older, less-defended form, criticized for difficulties of evidence and for the problem of multiple framers with multiple intentions.
• Original public meaning originalism focuses on how an ordinary, reasonably informed reader at the time of enactment would have understood the provision. This is the dominant form of modern originalism, defended by Justice Scalia, Justice Thomas, Larry Solum, Randy Barnett, Steven Calabresi, John McGinnis, and others. The argument is that the public meaning is what was actually ratified — the framers' private intentions are not law unless they were also publicly understood meanings.
• Original methods originalism holds that we should interpret the Constitution using the interpretive methods that were standard at the time of enactment, which themselves may include things like "vague terms should be given their evolving content" — meaning that even an originalist methodology can sometimes look like a living-constitutionalist outcome.

Originalism has a coherent intellectual structure. The argument is that a written constitution is intelligible as binding law only if its meaning is fixed at enactment; otherwise, what binds is not the text but whatever current judges decide the text means. Originalists also argue that originalism constrains judicial discretion: a judge committed to original public meaning cannot simply read their own preferences into vague constitutional language.

Living constitutionalism holds that the Constitution's meaning evolves with changing circumstances and changing societal understandings. The argument is that the framers wrote the Constitution in deliberately broad language ("liberty," "equal protection," "due process," "cruel and unusual") precisely because they expected the meaning to develop over time. Justice William Brennan's "Speech to the Text and Teaching Symposium" (1985) is the most famous defense.²⁴ David Strauss's The Living Constitution (2010) is the most accessible modern statement, defending what Strauss calls common-law constitutionalism: the Constitution evolves through case-by-case judicial development, the way the common law has always evolved, with courts adapting principles to new facts.²⁵ Jack Balkin's Living Originalism (2011) attempts to reconcile original public meaning with evolving application.²⁶

Living constitutionalism is sometimes caricatured as "judges making it up." The strongest version is more disciplined. Strauss argues that common-law constitutionalism is in fact more constraining than originalism, because it requires judges to work within an evolving body of precedent and reasoned argument that originalism's appeal to historical evidence does not. Brennan argued that living constitutionalism is the only way to apply timeless principles to circumstances the framers could not have foreseen — surveillance technology, biological engineering, mass communication.

Pluralism / passive virtues. Alexander Bickel's The Least Dangerous Branch (1962) developed an alternative tradition, in which the Court's job is sometimes to avoid deciding constitutional questions — to use justiciability doctrines, abstention, and other "passive virtues" to allow democratic processes to work themselves out. Bickel's view is sometimes called "judicial minimalism" or "constitutional avoidance." It has had an influence on a wide range of justices, including Felix Frankfurter and (in different forms) Cass Sunstein. The idea is that the Court should not always rush to resolve constitutional questions, especially when democratic deliberation is producing genuine learning.

Common-law constitutionalism. Strauss's term for an approach that combines living constitutionalism with the discipline of case-by-case adjudication, working from precedent and analogy rather than from grand interpretive theory. Common-law constitutionalism in this sense draws on Edmund Burke and Friedrich Hayek as well as on traditional Anglo-American legal practice.

Steel-manning each

The strongest case for originalism. Originalism takes seriously the claim that a written constitution is law only if its meaning is fixed. If meaning shifts with the times, then judges become a continuing constitutional convention, rewriting the Constitution by interpretation rather than by amendment. Originalism also produces a decision rule — look to public meaning at enactment — that constrains judicial discretion in a way no other methodology has equaled. Originalists argue that the alternative methods give judges too much room to read their preferences into the text. The fact that originalism sometimes produces outcomes that originalist judges personally dislike (Scalia's Crawford, for example, gave criminal defendants a new constitutional right) is offered as evidence that originalism actually constrains rather than rationalizes.

The strongest case for living constitutionalism. Living constitutionalism takes seriously the impossibility of applying eighteenth-century language to twenty-first-century circumstances without some interpretive evolution. The framers wrote "unreasonable searches and seizures" in 1789; how is that to be applied to electronic surveillance, drones, algorithmic policing? The framers wrote "cruel and unusual punishments"; how is that to be applied to twenty-five-year solitary confinement, to lethal injection protocols, to capital punishment of juveniles? Living constitutionalists argue that the choice is not between fidelity and judicial activism — it is between two kinds of interpretive choice, both of which require judgment, and that the "evolving" approach is at least honest about what is happening. Living constitutionalists also argue that the historical record on which originalists rely is itself a construction of modern advocates — that "the original public meaning" of contested clauses is often genuinely uncertain, and that originalist methodology gives the appearance of rigor without the substance.

The honest reader's takeaway. Both traditions are serious. Both have sophisticated defenders. Both can be applied in good faith and both can be applied as covers for ideological preference. The reader's job — and certainly the constitutional law student's job — is to engage with each on its own strongest terms, recognize when an interpreter is doing real work and when they are reaching for a methodology that conveniently produces a preferred outcome, and form judgments accordingly.

12.13 Stare decisis: when is overruling principled?

Stare decisis — Latin for "to stand by things decided" — is the doctrine that courts should follow their own previous decisions. The doctrine is not absolute; courts have always recognized that they can overrule precedent in the right circumstances. The contested question is when overruling is principled and when it is merely political.

The Supreme Court's modern stare decisis analysis typically considers several factors:²⁷

• Workability. Has the precedent proved difficult or impossible to apply? Has it produced inconsistent results across jurisdictions?
• Reliance. Have private parties or government actors substantially relied on the precedent in arranging their affairs? Reversing a precedent that many decisions have built on is more disruptive than reversing one that has been little relied upon.
• Doctrinal coherence. Does the precedent fit with the surrounding body of law? Has subsequent doctrine eroded the precedent's foundations?
• Factual changes. Have the empirical facts on which the precedent rested changed materially?
• Quality of reasoning. Was the original reasoning persuasive on its own terms?

These factors do not produce algorithmic answers. Reasonable judges applying the same factors can reach different conclusions about whether to overrule.

A list of major modern overrulings:

• Brown v. Board of Education (1954) overruled Plessy v. Ferguson (1896), rejecting "separate but equal" in public education.
• Lawrence v. Texas (2003) overruled Bowers v. Hardwick (1986), finding a substantive due process right to consensual same-sex intimate conduct.
• Citizens United v. FEC (2010) overruled Austin v. Michigan State Chamber of Commerce (1990) and parts of McConnell v. FEC (2003), holding that corporate independent expenditures are protected First Amendment speech.
• South Dakota v. Wayfair (2018) overruled Quill Corp. v. North Dakota (1992), allowing states to require sales-tax collection from out-of-state online retailers.
• Janus v. AFSCME (2018) overruled Abood v. Detroit Board of Education (1977), holding that public-sector union "fair share" fees on non-members violate the First Amendment.
• Dobbs v. Jackson Women's Health Organization (2022) overruled Roe v. Wade (1973) and Planned Parenthood v. Casey (1992), holding that the Constitution does not contain a right to abortion.
• Loper Bright Enterprises v. Raimondo (2024) overruled Chevron U.S.A. v. NRDC (1984), eliminating the doctrine of judicial deference to agency interpretation of ambiguous statutes.

Notice the political distribution. Some of these overrulings are widely celebrated by liberals (Brown, Lawrence) and resisted by conservatives. Others are celebrated by conservatives (Citizens United, Janus, Dobbs, Loper Bright) and resisted by liberals. Both progressives and conservatives have defended overruling precedent when the overruling cuts their way and complained about it when it cuts the other way.

This is the contested terrain of stare decisis doctrine. Is Brown a more legitimate overruling than Dobbs? Defenders of Brown argue yes: Plessy was originally wrongly decided, the factual premises of Plessy (about Black inferiority and the harms of segregation) were always false, and the Fourteenth Amendment's text was inconsistent with Plessy from the moment of enactment. Defenders of Dobbs argue something structurally similar: Roe was originally wrongly decided, the constitutional text contains no right to abortion, and the doctrinal foundations Roe purported to rest on (the substantive due process tradition through Lochner v. New York, 1905, and beyond) were already in disarray. Critics of Dobbs respond that the reliance interest was massive (50 years of women planning their lives around the Roe framework), that the workability factor cut against overruling (the Casey "undue burden" framework was working in lower courts), and that the speed of the change was destabilizing.

There is no method-neutral way to resolve these debates. The reader should grasp that stare decisis involves judgment, that judgment is influenced by interpretive philosophy, and that interpretive philosophy correlates (imperfectly but reliably) with appointing-president party. Whether a particular overruling was principled or political often depends on which side of the underlying issue you started on.

12.14 The federal courts and the political system

A common mistake is to think of the federal courts as the final and definitive interpreter of the Constitution. They are, on a great many questions, the most prominent. But they are not the only constitutional interpreter, and they are not the only branch with views about constitutional meaning.

Congress interprets the Constitution every time it passes legislation. The president interprets the Constitution every time the executive branch enforces or declines to enforce a statute. The states interpret federal constitutional questions in their own courts. Private actors — companies, unions, advocacy organizations — make constitutional arguments about how their behavior is or is not protected. Constitutional meaning emerges from the interaction of all these actors, of which the federal courts are one important participant.

The counter-majoritarian difficulty

The classic problem of federal judicial review is what Alexander Bickel called the counter-majoritarian difficulty. Why should an unelected, life-tenured judiciary be permitted to overturn the decisions of the people's elected representatives? In a democracy, the argument goes, the legitimate source of constitutional meaning is the political process — elections, legislative deliberation, executive accountability. Letting judges override that process is, on this view, an inherent tension within democratic government.

Bickel's The Least Dangerous Branch (1962) is the canonical statement. Bickel did not argue for abolishing judicial review; he argued that the Court should exercise it cautiously, with attention to its anti-democratic character. His "passive virtues" — abstention, justiciability doctrines, certiorari denials, narrow rulings — were tools the Court could use to minimize its anti-majoritarian footprint.

The majoritarian difficulty

In recent years, scholars including Keith Whittington, Robert Dahl, and others have pointed to a contrasting concern: the majoritarian difficulty. The Supreme Court, despite Bickel's worries, has historically tracked national majorities reasonably well over time. Justices are appointed by elected presidents and confirmed by elected senators. The Court's composition lags national politics by a decade or two but does not depart from it indefinitely. Whittington's argument is that the more interesting puzzle is not why an anti-majoritarian institution would have so much power but why a generally majoritarian institution is treated as a check on majorities.²⁸

The majoritarian view sees the Court as part of the political coalition that controls the elected branches, with judicial review functioning more often to facilitate majority preferences (by, for example, striking down state laws that conflict with national majorities) than to frustrate them.

Both views capture something. The Court is anti-majoritarian relative to current legislatures (as Bickel emphasized). It is also majoritarian relative to long-run national coalitions (as Whittington emphasized). Whether the gap between these — the gap between the Court's composition today and the country's preferences today — is small enough to make judicial review legitimate is one of the deep contested questions of American constitutional theory.

12.15 Looking ahead

This chapter has laid out the architecture. Chapter 13 covers the lower federal courts in operational detail — how cases get filed, how district courts manage their dockets, how circuit courts process appeals, and how the federal courts handle the most consequential kinds of cases (criminal trials, civil-rights litigation, administrative review). Chapter 14 covers the Supreme Court specifically — its docket, its processes, its current composition, the Roberts Court's distinctive jurisprudence, and the current debates over Court reform.

We will keep returning to the central tension of this chapter. Federal judges are members of an institution whose authority depends on its perceived neutrality. The empirical evidence is that judicial decisions correlate with political variables in ways that make pure neutrality untenable as a description. The honest position — that judges work in good faith within interpretive traditions that themselves have ideological valence — is harder to communicate than either "judges are umpires" or "judges are politicians." But it is the position the evidence supports, and it is the position from which serious thinking about the federal courts has to begin.
