Chapter 13. Lower Federal Courts — District, Circuit, and the Real Work of Federal Judging

"The Supreme Court hears about sixty cases a year on the merits. The lower federal courts decide more than four hundred thousand cases a year. If you want to know what federal law actually does in the lives of Americans, you have to look down, not up." — Adapted from the language of the Federal Judicial Center's annual training materials.

13.1 The Court Most Americans Never Hear About

Open any introductory American Government textbook to the chapter on the federal judiciary. Count the pages devoted to the Supreme Court. Then count the pages devoted to the United States District Courts and the United States Courts of Appeals.

In most textbooks, the ratio is something like fifteen to one. In some, it is closer to fifty to one. The Supreme Court gets the marquee treatment — the nine justices, the marble columns, the great cases of the constitutional canon. The lower federal courts, where almost all federal litigation actually lives and dies, are typically a half-page footnote.

That ratio is, frankly, journalistic. It tracks what the public reads about, not what federal courts actually do. The data look nothing like that ratio.

Consider the workload. In a typical recent year, the Supreme Court has issued roughly fifty to seventy signed opinions on the merits. Over the same period, the federal district courts have terminated roughly 355,000 to 400,000 cases — about 280,000 civil and 75,000 criminal — and the federal courts of appeals have terminated about 40,000 cases. To put it differently: for every one case the Supreme Court decides on the merits, the lower federal courts decide somewhere between five and eight thousand.

Now consider the consequences. When a federal district judge in the Eastern District of Virginia sentences a defendant to fifteen years in federal prison, that is a consequential federal-law event. When a circuit panel in the Eleventh Circuit affirms or reverses an injunction against an Alabama statute, the law of the Southeast changes. When a single district judge in the Northern District of Texas issues an order that a federally approved drug must be pulled from the market nationwide, the country reads about it the next morning — and then mostly forgets that the dispositive ruling came from a district judge, not from a justice. The lower federal courts are where federal law actually meets American life.

This chapter is the book's attempt to make you a lower-court-literate citizen. By the end of it, you will know:

• the geography of the ninety-four federal districts and the thirteen circuits;
• the actual workload of district, magistrate, bankruptcy, and circuit judges, and what their days look like;
• the institutional realities of three-judge panels, en banc review, and the so-called shadow docket;
• the procedural mechanics of how a single district judge can — sometimes — halt a federal policy nationwide, why both political parties have benefited from and complained about that practice, and the bipartisan reform conversation surrounding it;
• how lower-court ideological composition is changing, with concrete numbers from the Trump-1 (2017–2021), Biden (2021–2025), and Trump-2 (2025–) administrations;
• how circuits develop institutional reputations, and how circuit splits drive the Supreme Court's docket.

We will also do something most American Government textbooks avoid: we will look at the lower federal courts as political institutions — not in the partisan sense (most lower-court rulings are not partisan), but in the institutional sense. Where judges come from, what they do, who pays attention, and how power flows around them are first-order questions for understanding American government, not afterthoughts.

A note on tone before we begin. The federal judiciary, including the lower courts, has been a stable American institution for more than two centuries. It has also become more politically salient, more demographically transformed, and more procedurally contested in the last fifteen years than at any point since the desegregation era. We will hold both of those facts at once. Stability and stress, mostly-routine judging and high-stakes litigation, the trial judge in Tampa with three hundred routine cases on her docket and the trial judge in Amarillo whose single ruling is on the morning's front page — they are all part of the same institution.

13.2 The Architecture of Article III

The Constitution establishes the federal judiciary in Article III, Section 1:

"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."

In plain English: the Constitution creates the Supreme Court directly, and authorizes Congress to create whatever lower federal courts it wants. The First Congress used that authority almost immediately, passing the Judiciary Act of 1789, which created thirteen district courts (one per state then in the Union) and three circuit courts (which originally had different functions than today's courts of appeals — they were trial courts as well, staffed by Supreme Court justices riding circuit on horseback). The basic two-tier-plus-Supreme-Court architecture has been with us, in evolving form, ever since.

Today the Article III judicial branch consists of:

• The Supreme Court of the United States — one court, nine justices.
• The United States Courts of Appeals — thirteen circuits.
• The United States District Courts — ninety-four districts.

Each of these courts is staffed by Article III judges: nominated by the President, confirmed by the Senate, holding their offices "during good Behaviour" (i.e., for life unless impeached), and constitutionally protected against having their salaries reduced. Article III protections matter because they are designed to insulate federal judges from political pressure. A judge who cannot be fired and cannot have her salary cut is, in theory, free to rule against the President who appointed her, against the Senate that confirmed her, and against the political mood of the moment. In practice, of course, judges are human beings with views; the Article III protections do not produce ideological neutrality, but they do produce a kind of structural independence that an at-will judge would not have.

Alongside the Article III courts, Congress has created a number of Article I courts and Article I judicial officers — judges who are not life-tenured and not protected by the salary clause, but who exercise federal judicial functions. The most numerous and important categories are magistrate judges (about 530 of them) and bankruptcy judges (about 340). We will return to both.

A simple mental map:

                    SUPREME COURT (Art. III)

We now walk down that map, starting at the bottom — where most federal litigation begins.

13.3 The District Courts: Where Federal Trials Happen

13.3.1 The geography of the ninety-four districts

Every state has at least one federal judicial district. Smaller-population states are a single district covering the whole state — Alaska is the District of Alaska, Maine is the District of Maine, Wyoming is the District of Wyoming. More populous states are divided into multiple districts.

California, the largest state, has four:

• Northern District of California (San Francisco, Oakland, San Jose) — Silicon Valley litigation, much of the federal antitrust and patent docket.
• Eastern District of California (Sacramento, Fresno, Bakersfield) — agriculture, the Central Valley, eastern Sierra Nevada.
• Central District of California (Los Angeles, Santa Ana, Riverside) — by some measures the busiest federal trial court in the country.
• Southern District of California (San Diego, Imperial County) — border, immigration, and trans-Pacific commerce.

Texas has four districts (Northern, Eastern, Southern, Western), New York has four (Northern, Southern, Eastern, Western), Florida has three (Northern, Middle, Southern), and so on. The basic logic is geographic: districts try to keep federal courthouses within reasonable travel distance for litigants, jurors, and witnesses.

Beyond the fifty states, the federal district court system covers the District of Columbia, Puerto Rico, the Virgin Islands, Guam, and the Northern Mariana Islands. Districts in the territories are slightly different in their judges' tenure (the Virgin Islands, Guam, and Northern Marianas have ten-year-term judges rather than life-tenured Article III judges), but they perform the same federal-court function.

13.3.2 Who staffs the district courts

There are approximately 673 authorized district judgeships across the ninety-four districts (Congress has not added a substantial new wave of judgeships since 1990, and there is bipartisan pressure to create more). Active judges — those carrying a full caseload — number around that figure when the seats are filled.

Above and beyond the active judges, the federal bench has senior judges: judges who have met statutory age-and-service requirements (the so-called Rule of 80, where a judge's age plus years of service equals at least 80, and they are at least 65) and who have elected senior status. Senior judges semi-retire — they keep an office and a courtroom, but they choose how much of a docket to carry. Some senior judges carry a near-full load; others handle a focused caseload of, say, prisoner habeas petitions or social-security appeals. Across the district courts, there are typically 200 to 300 senior judges active in any given year. They do an enormous amount of the system's work.

Add in magistrate judges — about 530 of them across the ninety-four districts — and the actual federal trial-court bench is closer to 1,400 judicial officers than the headline 673 number suggests.

13.3.3 The actual workload

In a recent typical fiscal year:

• Federal district courts received ~280,000 civil cases and ~70,000 to 75,000 criminal cases — about 355,000 case filings in total.
• The average per-judgeship caseload is thus roughly 430 to 500 weighted filings per active judge per year — though the Administrative Office of the U.S. Courts uses weighted filings, where, e.g., a complex multidistrict case counts more than a routine debt-collection case.

What a federal district judge actually does on a typical day:

• Rule on motions. This is the bulk of the work. Motions to dismiss, motions for summary judgment, discovery disputes, motions to suppress, sentencing motions, motions in limine. Many are routine; some are dispositive of the entire case.
• Manage cases. Schedule discovery, set trial dates, hold status conferences, encourage settlement. The Federal Rules of Civil Procedure place active case management in the judge's hands.
• Conduct evidentiary hearings. Suppression hearings, preliminary-injunction hearings, evidentiary hearings on disputed facts in habeas or asset-forfeiture cases.
• Try cases. Federal district courts are the only Article III courts where trials normally happen. But trials are rare — the so-called "vanishing trial" phenomenon. In a typical year, only about 1 percent of federal civil cases reach trial, and fewer than 3 percent of federal criminal cases reach trial. Almost everything settles or pleads.
• Sentence convicted defendants. A central part of the federal criminal docket. Sentencing has been an evolving area since United States v. Booker (2005), which made the U.S. Sentencing Guidelines advisory rather than mandatory. We return to this below.
• Write opinions. Mostly short — a four-page order denying a motion to dismiss, a ten-page summary-judgment opinion, occasionally a substantial opinion in a major case. Most district-court opinions are not formally published in the Federal Reporter and are not binding precedent — though they are often cited and influential.

The day-to-day pace is intense. A federal district judge at any given moment is responsible for several hundred open cases. Most are managed through the docket — a chronological list of every open matter, every deadline, every pending motion — and the judge moves through it the way a hospital chief of medicine moves through a service: triage, decision, next.

13.3.4 Magistrate judges: the unsung workhorses

Created in their modern form by the Federal Magistrates Act of 1968 (with major expansions in 1976 and 1979), magistrate judges are Article I judges appointed by the district judges of their court for eight-year renewable terms (or four years for part-time magistrates). They are not life-tenured; they are not nominated by the President or confirmed by the Senate. But they handle an enormous portion of federal court business.

What magistrates do:

• Pretrial matters in criminal cases. Initial appearances, detention hearings, search-warrant applications, arraignments, preliminary hearings.
• Discovery disputes in civil cases. When parties fight about whether one of them has to produce a particular set of documents, the dispute typically goes first to a magistrate.
• Social Security disability appeals. A massive subset of the federal civil docket; magistrates handle most of it on a referral system.
• Habeas corpus screening. Magistrates do the initial review of state-prisoner petitions.
• Settlement conferences. Parties often consent to a magistrate facilitating settlement.
• Civil trials with parties' consent. A litigant in federal court can consent to having her entire case — including a jury trial — heard by a magistrate judge. About 15 percent of federal civil trials are now conducted by magistrate judges on consent.

If you took every magistrate judge out of the system tomorrow, the federal trial courts would collapse within weeks. The magistrate bench is one of the great administrative innovations in the modern federal judiciary.

13.4 The Courts of Appeals: Thirteen Circuits, One Country

13.4.1 The map

The thirteen circuits are:

• First Circuit. Maine, Massachusetts, New Hampshire, Rhode Island, Puerto Rico. (Boston.)
• Second Circuit. New York, Connecticut, Vermont. (New York City.) Heavy financial-services and securities docket.
• Third Circuit. Pennsylvania, New Jersey, Delaware, the Virgin Islands. (Philadelphia.) Heavy corporate docket — Delaware is the corporate-charter capital of the country.
• Fourth Circuit. Maryland, Virginia, West Virginia, North Carolina, South Carolina. (Richmond.)
• Fifth Circuit. Louisiana, Mississippi, Texas. (New Orleans.)
• Sixth Circuit. Michigan, Ohio, Kentucky, Tennessee. (Cincinnati.)
• Seventh Circuit. Illinois, Indiana, Wisconsin. (Chicago.)
• Eighth Circuit. Minnesota, North Dakota, South Dakota, Nebraska, Iowa, Missouri, Arkansas. (St. Louis.)
• Ninth Circuit. California, Oregon, Washington, Nevada, Arizona, Montana, Idaho, Alaska, Hawaii, Guam, Northern Mariana Islands. (San Francisco.) The largest circuit by population, area, and judges.
• Tenth Circuit. Colorado, Wyoming, Utah, New Mexico, Kansas, Oklahoma. (Denver.)
• Eleventh Circuit. Florida, Georgia, Alabama. (Atlanta.) Created in 1981 by splitting the former (very large) Fifth Circuit.
• D.C. Circuit. Federal cases arising in the District of Columbia, plus a vast portion of administrative-law litigation involving federal agencies. (Washington, DC.)
• Federal Circuit. Nationwide jurisdiction over patents, federal claims, veterans' benefits appeals, and certain trade and government-employment cases. (Washington, DC.)

13.4.2 How a circuit court works

A federal court of appeals usually decides cases through three-judge panels. Panels are typically drawn at random from the active judges of the circuit, augmented by senior judges on the circuit (who sometimes elect to sit on panels) and visiting judges from other circuits or from the district courts within the circuit (assigned for particular sittings to manage workload).

After a panel decides a case, the losing party can:

1. Petition for panel rehearing — asking the same three judges to reconsider. Almost always denied.
2. Petition for rehearing en banc — asking the entire active membership of the circuit (or, in the Ninth Circuit, an eleven-judge "limited en banc" panel, given the circuit's size of twenty-nine active judgeships) to rehear the case. Granted rarely — usually less than 1 percent of cases — but consequential when granted.
3. Petition for certiorari at the Supreme Court. Granted on roughly 1 percent of petitions.

Most appeals are decided by panel without oral argument and without published opinion. Roughly 80 to 85 percent of federal appellate decisions are unpublished — they are nonprecedential dispositions, often a few pages, telling the parties who won and why, but not establishing binding doctrine for the circuit. The published, precedential decisions are the public face of the courts of appeals; the unpublished decisions are most of the actual work.

13.4.3 Senior, visiting, and active judges

Each circuit has an authorized number of active judgeships:

Plus senior judges, who often handle a substantial caseload. Across all thirteen circuits, the active appellate bench is about 180 judges; the working bench, including senior judges and visiting district judges, is closer to 300.

13.4.4 Why circuit identity matters: jurisprudential reputations

Different circuits have, over time, developed reputations — institutional cultures and ideological tilts that shape how cases are decided within them. These reputations are not stereotypes; they are tracked by political scientists and law-and-courts scholars using compositional data and ideal-point estimates of judicial voting (Epstein, Landes, and Posner; Sunstein; Boyd; Choi-Gulati-Posner; among others).

A few of the most institutionally significant circuit identities, as of 2026:

The Fifth Circuit (Louisiana, Mississippi, Texas). As of 2025, the Fifth Circuit is widely characterized as the most conservative federal court of appeals. Of its seventeen active judges, approximately twelve were appointed by Republican presidents — six by Donald Trump in his first term, two by George W. Bush, and several earlier. The circuit's docket includes a steady stream of major administrative-law and culture-war cases, in part because Texas is large, populous, conservative-leaning in its state government, and an active state-versus-federal-government litigant. Its prominence in nationwide-injunction litigation against federal policies during the Biden administration was a defining institutional feature of those years.

The Ninth Circuit (the West). Long perceived as the most liberal federal court of appeals — a reputation fueled by its size, its location, and high-profile reversals at the Supreme Court — the Ninth has shifted considerably over the past decade. Trump-1 nominees to the Ninth (ten of them, an unusually high number) substantially altered its composition; Biden nominees rebalanced it. As of 2025, the Ninth's active judges are roughly evenly split between Democratic and Republican appointees. The "wild-eyed Ninth Circuit" caricature — popular in 1990s and 2000s political commentary — does not describe the contemporary court.

The D.C. Circuit. Often called the "second-most-important court in the country" because of its specialized jurisdiction over administrative-law challenges to federal agency action. Statutes including the Clean Air Act, the Communications Act, the National Labor Relations Act, and many others designate the D.C. Circuit (sometimes exclusively) as the venue for review of the relevant agencies' decisions. The D.C. Circuit has historically been a primary "feeder" to the Supreme Court — Justices John Roberts, Clarence Thomas, Ruth Bader Ginsburg, Antonin Scalia, Brett Kavanaugh, and Ketanji Brown Jackson all served on the D.C. Circuit before their elevation. The D.C. Circuit's institutional culture emphasizes administrative-law expertise and a particular interest in how courts review agency interpretations of statutes.

The Fourth Circuit. Once known as one of the most conservative circuits in the late twentieth century, the Fourth has become substantially more moderate or liberal-leaning in the twenty-first, especially after a wave of Obama and Biden appointments. As of 2025, of its fifteen active judgeships, a majority are Democratic appointees — a striking change from 2000.

The Eleventh Circuit. Florida, Georgia, Alabama. Substantially conservative in its current composition, with Trump-1 having transformed its lineup. The circuit handles a steady stream of Florida-originating litigation that often has national salience.

The lesson is that circuit composition is not destiny but it matters. A litigant whose case can be filed in either the Ninth or the Fifth Circuit will get different oral-argument environments, different precedent, and (sometimes) different outcomes. That fact is the structural reality behind much of what we will discuss under the heading of forum-shopping.

13.4.5 Circuit splits as the engine of Supreme Court review

When the same federal-law question is decided differently in different circuits, the result is a circuit split. The Supreme Court's primary criterion for granting certiorari is the resolution of circuit splits — the Court's role in the federal hierarchy is to ensure uniform federal law, and the splits are where uniformity has broken down.

Three concrete recent examples:

1. Mifepristone access (2023–2024). The Fifth Circuit's narrow read of the statutory standing of medical-association plaintiffs and its skepticism of FDA approval procedures was in tension with rulings from other district courts. The Supreme Court granted certiorari and unanimously reversed in FDA v. Alliance for Hippocratic Medicine (June 2024), holding that the plaintiffs lacked Article III standing.

2. Section 230 and platform liability (2022–2023). Different circuits had given different readings of when an internet platform's algorithmic recommendations were "publication" within Section 230 of the Communications Decency Act. The Supreme Court resolved the Section 230 question relatively narrowly in Twitter v. Taamneh (2023) and Gonzalez v. Google (2023).

3. Bivens claims and federal officer liability (multiple recent terms). Whether and when a plaintiff can sue a federal officer for constitutional violations under the Bivens v. Six Unknown Named Agents (1971) doctrine has produced repeated circuit splits, with the Court generally narrowing Bivens (e.g., Egbert v. Boule, 2022).

Circuit splits are the link between the lower courts and the Supreme Court's docket. Most cases in the Supreme Court's merits docket arrive there because the circuits below disagreed. The lower courts are not just inferior tribunals; they are the doctrinal laboratories where federal law is initially worked out.

13.5 The Specialized Courts

In addition to the geographic district and circuit courts, the federal judiciary includes a number of specialized courts. These are sometimes Article I, sometimes Article III, depending on Congress's choices.

• United States Tax Court (Article I). Hears cases challenging IRS deficiency determinations. Nineteen judges, fifteen-year terms.
• United States Court of Federal Claims (Article I). Hears monetary claims against the United States — government-contract disputes, takings claims, certain tax refunds. Sixteen judges, fifteen-year terms.
• United States Court of International Trade (Article III). New York-based. Hears trade-related disputes — tariffs, customs, antidumping duties. Nine judges.
• Foreign Intelligence Surveillance Court (FISC) (Article III). The notorious "FISA Court." Sits in Washington, DC. Composed of eleven federal district judges designated by the Chief Justice on a part-time, rotating basis. Reviews surveillance applications by the federal government against suspected agents of foreign powers.
• United States Court of Appeals for Veterans Claims (Article I). Reviews decisions of the Board of Veterans' Appeals. Nine judges, fifteen-year terms.
• United States Court of Appeals for the Armed Forces (Article I). The civilian appellate court for military justice. Five judges, fifteen-year terms.

A note on the Federal Circuit's patent monopoly. Since 1982, the Federal Circuit has had exclusive nationwide appellate jurisdiction over patent cases — appeals from any district court patent ruling go to the Federal Circuit, not to the regional circuit. The justification was uniformity: before 1982, different regional circuits had developed inconsistent patent doctrines, leading to forum-shopping and uncertainty. The result has been doctrinally consequential. Some scholars (including Mark Lemley and others in the patent-law academy) argue that concentrating patent law in a single circuit has produced doctrinally idiosyncratic outcomes — particular tilts in claim construction, in injunction doctrine, in the patent-eligibility requirements under § 101 — that may not have emerged with multi-circuit competition. Other scholars defend the consolidation as having produced predictability the prior regime lacked. The debate is ongoing. The point for our purposes is structural: when Congress concentrates a doctrinal area in a single circuit, the institutional consequences can be substantial and not always anticipated.

13.6 Bankruptcy Courts and the Constitutional Puzzle

The roughly 340 bankruptcy judges are Article I judges, appointed by the courts of appeals for fourteen-year terms, attached administratively to the district courts. They hear bankruptcy filings under the Bankruptcy Code (Title 11 of the United States Code) — about 400,000 to 500,000 bankruptcy cases per year, mostly Chapter 7 (liquidation) and Chapter 13 (individual reorganization), plus a smaller but high-stakes Chapter 11 (corporate reorganization) docket.

The constitutional puzzle: if bankruptcy judges are not Article III judges and do not have life tenure, what powers can they constitutionally exercise? The Supreme Court addressed this in Stern v. Marshall (2011), an opinion arising out of the Anna Nicole Smith inheritance dispute. The Court held that a bankruptcy judge could not constitutionally enter final judgment on a state-law counterclaim that was not necessary to the resolution of the bankruptcy claim — that final judgment on such matters had to be entered by an Article III judge, even if the bankruptcy judge could submit proposed findings.

Stern v. Marshall did not destroy the bankruptcy-court system, but it created a category of "Stern claims" — issues on which a bankruptcy judge cannot enter final judgment without consent — and added a significant procedural complexity to bankruptcy litigation. The doctrine remains contested and the boundary cases continue to be litigated. The lesson is that the constitutional architecture of Article III matters not just symbolically but operationally: who can decide what is itself a structural question.

13.7 Confirmation Politics and the Composition of the Lower Courts

13.7.1 The 2013 nuclear option and what it changed

In November 2013, the Senate Democratic majority, frustrated by Republican filibusters of executive-branch and judicial nominees, invoked the so-called "nuclear option" — a parliamentary maneuver to lower the cloture threshold for ending debate on most nominations from sixty votes to a simple majority. The change applied to executive-branch nominees and to Article III judicial nominees other than Supreme Court nominees.

In April 2017, with the Republican majority unable to break a Democratic filibuster of Neil Gorsuch's Supreme Court nomination, the Senate Republican majority extended the nuclear option to Supreme Court nominations as well.

The combined effect: every federal judicial nomination, from district court through Supreme Court, can now be confirmed by a simple-majority Senate vote. The filibuster is not available to the minority for any judicial nomination. This is the single most consequential structural change to the federal judiciary in the past two decades.

13.7.2 Confirmation totals by administration (post-nuclear option)

The numbers across the most recent administrations:

Trump 1 (2017–2021):

• 234 federal Article III judicial confirmations across four years.
• 3 Supreme Court justices (Gorsuch 2017, Kavanaugh 2018, Barrett 2020).
• 54 circuit court judges — a record pace, transforming several circuits.
• 174 district court judges.

Biden (2021–2025):

• 235 federal Article III judicial confirmations across four years — narrowly exceeding the Trump-1 pace.
• 1 Supreme Court justice (Jackson 2022).
• 45 circuit court judges.
• 187 district court judges.
• The Biden cohort was the most demographically diverse in federal-judiciary history: a majority of confirmees were women, and a substantial majority were people of color. About a quarter of confirmees were former public defenders or civil-rights lawyers, a deliberate departure from the prosecutor-and-corporate-lawyer pipeline that had dominated prior administrations.

Trump 2 (2025–):

• Confirmations ongoing as of 2026. Pace and composition tracking comparable to Trump 1, with Senate Republican majority and the post-nuclear-option process.

A few institutional observations:

1. Both parties have used the post-2013 simple-majority rule to confirm judges at historically high rates. Both have transformed the lower courts they inherited.
2. The demographic and ideological characteristics of the cohorts differ. Trump-era confirmees skew younger (mean age in early forties at confirmation), more ideologically conservative (often with Federalist Society backgrounds), and more uniformly drawn from prosecutorial or executive-branch backgrounds. Biden-era confirmees skew slightly older, more demographically diverse, and more drawn from public-defender, civil-rights-litigation, and academic backgrounds.
3. The competing visions are about both who the judges are and what kinds of cases they have prepared for. A federal judge whose pre-confirmation career was as a federal prosecutor will, on average, approach criminal sentencing differently from a federal judge whose pre-confirmation career was as a federal defender. Neither is right or wrong; the point is that the bench's experience profile is changing in measurable ways.

13.7.3 Blue slips and the senatorial-courtesy tradition

For more than a century, the Senate has observed a custom called the "blue slip" for district-court (and historically circuit-court) nominations. When the President nominates a district-court judge, the Senate Judiciary Committee chairman sends a blue-colored form to each home-state senator. The senators return the blue slips indicating support, opposition, or no objection.

The specific weight given to blue slips has varied by chairman. Some chairmen treated a negative blue slip as a veto — no hearing, no vote. Others treated it as advisory. As of the recent past, the convention has tilted toward giving home-state senators substantial deference for district-court nominations (where geographic and local-bar familiarity matters) but less deference for circuit-court nominations (where the seat covers multiple states).

The blue-slip tradition is one of the few surviving forms of senatorial courtesy in the modern judicial-confirmation process. It remains important especially for district-court nominations in states with senators from the opposite party of the President. A Republican president nominating a district judge for, say, the District of Connecticut, has historically had to consult with Connecticut's Democratic senators — and a Democratic president nominating a district judge for, say, the Eastern District of Texas, has historically had to consult with Texas's Republican senators.

13.7.4 The judicial-vacancy backlog

As of 2026, federal judicial vacancies number in the dozens at any given time. The Federal Judicial Vacancy List published by the Administrative Office of the U.S. Courts tracks current openings. Vacancies create caseload pressure: when a district has a vacant judgeship, the remaining judges absorb the caseload, and senior judges and visiting judges often fill in. Long-term vacancies have become a source of administrative stress, especially in districts with already-high caseload-per-judge ratios (the Eastern District of California has been the most-cited example for nearly a decade).

The pattern of vacancies is partly a function of presidential-and-Senate alignment. When the same party controls both, confirmations move quickly. When they are split, vacancies accumulate.

13.8 Where Lower-Court Politics Happens

We turn now to four phenomena that have made the lower federal courts more politically salient in the past decade than they were in the prior generation. Each of them is institutional, not personal — they are about how the system is organized, not about any particular judge's politics.

13.8.1 Nationwide injunctions and the "single-judge division" problem

A federal district court is a trial court. By traditional doctrine, a trial court's remedy in a case is limited to the parties before it — the order runs against the named defendant on behalf of the named plaintiff. But for several decades, federal district courts have, with increasing frequency, issued nationwide injunctions (also called "universal injunctions"): orders that purport to halt the operation of a federal policy not just as to the parties in the case but as to anyone in the country.

The practice is not limited to one party's policies:

• Against the Trump-1 administration: Federal district courts in California, Hawaii, Maryland, Washington State, and elsewhere issued nationwide injunctions against versions of the Trump-1 travel ban, against the rescission of DACA, against various immigration-enforcement policies, against the family-separation policy, and against various contraception-mandate accommodations.
• Against the Biden administration: Federal district courts in Texas, Louisiana, Florida, and elsewhere issued nationwide injunctions against the federal vaccine mandates for federal contractors, against the OSHA emergency temporary standard, against federal student-loan-forgiveness orders, against various immigration-enforcement policies, against rules issued under the Affordable Care Act and Title IX, and against the FDA's approval of mifepristone (in part).
• Against the Trump-2 administration (early 2025–2026): Federal district courts have already issued nationwide and broad-form injunctions against several Trump-2 immigration policies, against executive orders attempting to limit federal grant programs, and against some workforce-restructuring orders. The institutional pattern is now more than a decade old and shows no sign of slowing under any party.

The pattern is bipartisan. Litigants on both sides have pursued — and obtained — district-court orders that halt federal policy nationwide. Both administrations have complained, often in identical language, that a single unelected district judge should not be able to halt the policy of a nationally elected administration. The Solicitor General's Office under both Republican and Democratic administrations has filed substantively similar emergency-stay applications complaining about the same structural feature — only the policies at issue change.

The doctrinal critique of nationwide injunctions is also bipartisan in legal academia. Sam Bray (UCLA, then Notre Dame) argued in a series of influential articles, beginning with his 2017 Harvard Law Review piece "Multiple Chancellors: Reforming the National Injunction," that nationwide injunctions are inconsistent with traditional equitable-remedies doctrine, with the constitutional limits on Article III judicial power, and with sound policy. Bray's central argument is historical: equity courts traditionally issued relief running between the parties, not at large; the modern nationwide injunction is a doctrinal innovation of roughly the past sixty years, not a long-standing federal-court tool. Howard Wasserman (FIU) has elaborated the structural critique in subsequent work, distinguishing universal injunctions (which run against everyone) from precedential injunctions (which bind only the named parties but produce stare-decisis effects). On the other side, Mila Sohoni (Stanford) defended the practice in "The Lost History of the 'Universal' Injunction," arguing that the historical record is more mixed than Bray suggests and that practical necessity sometimes requires broader relief. Amanda Frost (UVA) has written that bipartisan use of the practice undermines partisan critiques and that workable reforms must address the underlying problem of inconsistent regulation, not just the remedy.

Within the Supreme Court, the issue has produced unusual cross-ideological convergence. Justice Gorsuch, in a series of concurring and dissenting opinions including Department of Homeland Security v. New York (2020) and Trump v. Hawaii (2018, concurring), has argued that nationwide injunctions exceed the constitutional authority of district courts and should be sharply limited or abolished. Justice Thomas has written similarly. Justice Kagan, in a widely cited 2022 Northwestern Law speech, expressed her own reservations: "It just can't be right that one district judge can stop a nationwide policy in its tracks and leave it stopped for the years that it takes to go through normal process." When Justices Kagan, Gorsuch, and Thomas agree that a procedural device is institutionally suspect, the cross-ideological signal is genuine.

The countervailing argument: when a federal policy is plainly unlawful and would cause widespread harm, an injunction limited to the named plaintiffs would leave equally situated parties to relitigate the same issue thousands of times. The administrative-state machinery cannot, in practice, comply with a federal rule for some people but not others — the IRS cannot apply one tax rule to the named plaintiff and a different rule to everyone else without producing chaos. The argument is not frivolous; it explains why nationwide injunctions have persisted despite the doctrinal critique. Defenders also note that narrowing the remedy without addressing class-action restrictions and standing doctrine would leave plaintiffs without effective relief in many cases — the doctrine functions as a release valve in a remedial system that has, for separate reasons, become harder to use at class-wide scale.

The structural concern about single-judge divisions layers onto the nationwide-injunction problem. Several federal districts have geographic divisions in which only one judge sits. The most-cited examples:

• The Amarillo Division of the Northern District of Texas. Judge Matthew Kacsmaryk, appointed by President Trump in 2019, is the only active judge sitting in the Amarillo Division. As a structural matter, every civil case filed in Amarillo is assigned to him at a 100 percent rate. The division is therefore a venue choice that produces a judicial choice — not by formal design, but by geographic and assignment realities.
• The Wichita Falls Division of the Northern District of Texas. Judge Reed O'Connor (G.W. Bush appointee, 2007) sits as the sole active judge there. Wichita Falls has been the venue for several major recent cases, including Texas v. United States, the 2018 ACA challenge that produced an initial district-court ruling striking down the entire Affordable Care Act (later substantially modified by the Fifth Circuit and ultimately reversed by the Supreme Court on standing grounds in California v. Texas, 2021).
• The Marshall Division of the Eastern District of Texas. Long famous as a patent-litigation venue (the docket of Judge T. John Ward in the 2000s was a major patent forum), Marshall has more recently been chosen for non-patent civil-rights and administrative-law challenges. Currently a small number of judges sit in Marshall; the assignment lottery is therefore not single-judge but is small enough that strategic filing can shift the probability distribution materially.

Critics of the practice (across the spectrum) argue that this allows litigants to effectively choose their judge, undermining the appearance of judicial neutrality. The argument has been made by Sam Bray, by Stephen Vladeck (University of Texas, then Georgetown) in his shadow-docket work, and by Steve Calabresi (Northwestern, co-founder of the Federalist Society) in a notable 2023 op-ed that surprised many on the right. Vladeck's empirical work documents that progressive litigators have used analogous strategies in California's Northern District (San Francisco) for environmental and immigration challenges, where the active-judge composition is more favorable to plaintiffs seeking to halt federal action against state and local interests. The practice is bidirectional: the venue strategy and the single-judge-division strategy are tools, and tools have been used by litigants on both sides.

To pair the examples concretely: the Northern District of California has been used heavily by progressive state attorneys general and immigration-rights organizations during Republican administrations to obtain injunctions against federal policies. The Amarillo and Wichita Falls divisions have been used heavily by conservative state attorneys general and faith-based organizations during Democratic administrations to obtain injunctions against federal policies. The judges in question — Kacsmaryk, O'Connor, and several Northern California judges — have been singled out by partisans on the opposite side as illegitimate; defenders of each have responded that the judges are following the law as they read it. The institutional question is not whether any individual judge is acting in good faith but whether the system's design produces venue effects that the system did not intend and cannot easily justify.

In response, the Judicial Conference of the United States (the policymaking body for the federal judiciary, chaired by the Chief Justice) issued guidance in March 2024 recommending that civil cases of broad national importance be assigned at random across the entire district, rather than within a single division. The guidance came from the Conference's Committee on Court Administration and Case Management; it was endorsed publicly by Chief Justice Roberts in his 2024 year-end report. The guidance was formally voluntary; some districts adopted it (the Northern District of Texas declined to adopt it as a matter of formal policy), others did not. The guidance itself became politically contested — defenders of the existing system argued that the Judicial Conference was responding to political pressure rather than principle, that the existing assignment rules had been in place for decades, and that the guidance singled out conservative-friendly venues; critics of the existing system argued that the guidance was overdue, modest, and consistent with the practice already used in many districts. Senator John Cornyn (R-TX) and Senator Charles Schumer (D-NY) both expressed concerns about the guidance, but for opposite reasons. The structural issue does not have an obvious bipartisan resolution.

Case study 02 of this chapter walks through the mifepristone case in detail, including the structural critique and the institutional response. The point for now is that nationwide injunctions and forum-shopping are bipartisan phenomena that have generated bipartisan reform proposals. They are not "one party's problem."

13.8.2 The transformation of the Fifth Circuit

We have already given the numbers: as of 2025, approximately twelve of seventeen active Fifth Circuit judges are Republican appointees, six of them appointed by President Trump in his first term. The transformation has changed the institutional character of the circuit. It now decides administrative-law cases against federal agency action, statutory cases under federal civil-rights statutes, and constitutional cases on social policy in ways that, on average, are noticeably different from how the Fifth Circuit decided such cases fifteen years ago.

The compositional shift is best understood as the cumulative result of three factors: (1) the post-2013 simple-majority confirmation rule, which made any blocked-by-filibuster strategy unavailable, (2) an aggressive Trump-1 nomination pace combined with a Senate Republican majority willing to confirm rapidly, and (3) the geographic incidence of vacancies — the Fifth Circuit had several seats turn over during a single four-year period, allowing one administration to reshape the bench substantially. None of these factors is unique or unprecedented; the combination, in those years, was unusual.

A short list of recent Fifth Circuit decisions that illustrate the institutional shift includes the panel ruling in Alliance for Hippocratic Medicine v. FDA (2023, modified panel decision on mifepristone), the en banc ruling in Jarkesy v. SEC (2022, finding the SEC's in-house adjudication of certain securities-fraud cases unconstitutional, later affirmed by the Supreme Court in 2024), and the panel decision in Texas v. United States on the OSHA emergency temporary standard (2022). Each of these was reviewed (or stayed) by the Supreme Court; the Court has affirmed the Fifth Circuit on some questions and reversed it on others, sometimes by 9–0 margins. The relevant institutional fact is not that the Fifth Circuit always wins or always loses at the Supreme Court, but that it has become the most consequential circuit for administrative-law and culture-war litigation against federal policy during Democratic administrations.

This is not a value judgment. Other circuits have undergone analogous transformations in other directions. The Fourth Circuit, in 2000, had a strongly conservative reputation and was widely cited as the place to file for plaintiffs seeking conservative outcomes; the Fourth Circuit, in 2025, has a Democratic-appointee majority and a different institutional reputation. The Eleventh Circuit moved in the opposite direction, becoming substantially more conservative through Trump-1 appointments. The Ninth Circuit moved toward the center. The point is institutional: circuit composition is consequential, it changes over time, and the rate of change is accelerated by the post-2013 simple-majority confirmation rule. A reader who wants to understand the contemporary federal judiciary cannot rely on circuit reputations from twenty years ago; the bench has changed.

13.8.3 The shadow docket

The "shadow docket" is a term coined by William Baude (University of Chicago) in 2015 to describe the Supreme Court's non-merits orders — emergency stays, denials of cert, summary reversals, applications for injunctive relief. Most of these orders are short, often unsigned, and issued without full briefing or oral argument.

Many shadow-docket orders are inconsequential. But a growing subset are not: they are emergency rulings on applications that originated in the lower federal courts, in which a party has obtained or been denied an injunction, and the Supreme Court is asked to stay or vacate that injunction pending further proceedings. The Court's stay decision often has the practical effect of resolving the case — federal policy either continues or is halted for a year or two, by which time the litigation may have evolved or become moot.

The shadow docket and the lower federal courts are tightly connected. An emergency Supreme Court order is meaningful only because there is a lower-court order to stay. The growth in shadow-docket activity is partly a function of how often lower courts have been issuing nationwide injunctions and emergency orders in politically salient cases. Stephen Vladeck's 2023 book The Shadow Docket documents the trend in detail and offers a critique. Defenders of the Court's emergency-order practice argue that the Court has to act quickly when lower courts issue nationwide injunctions on emergency timelines.

13.8.4 District judges and Supreme Court precedent

The traditional answer to the question "must a federal district judge follow Supreme Court precedent?" is yes, always, without exception. Hutto v. Davis (1982) put the rule plainly: lower federal courts must follow Supreme Court precedent until the Supreme Court itself overrules it.

In the past few years, a small number of high-profile district-court rulings have been read as straining against this rule — distinguishing binding Supreme Court precedent on grounds that critics describe as artificial, or signaling discomfort with binding precedent in language that goes beyond mere distinction. These are exceptional cases, not the norm. The overwhelming majority of district-court rulings every year hew faithfully to Supreme Court doctrine.

But the cases that strain are noticed, and they generate institutional concern. The traditional model — district judges as faithful agents of binding Supreme Court doctrine — depends on a norm of fidelity that, like other norms in American government, can erode. We mention the issue here because it is part of the contemporary lower-court landscape, not because it is the dominant feature.

13.8.5 Recent contested cases: a tour through the lower-court docket

To make the abstract concrete, here is a brief tour of recent and ongoing high-profile lower-court litigation. These are cases that have shaped, are shaping, or will shape American government during this textbook's adoption period. We pick them because they illustrate the institutional dynamics already discussed — venue, panel composition, emergency stays, en banc review — not because they are the most ideologically interesting.

The mifepristone litigation (2022–2024). Filed in the Amarillo Division of the Northern District of Texas in November 2022 by a coalition of medical organizations opposed to abortion. Judge Kacsmaryk issued a preliminary order in April 2023 staying the FDA's 2000 approval of mifepristone. The Fifth Circuit (panel: Ho, Elrod, Wilson — all Republican appointees) modified the order, narrowing it to the FDA's 2016 and 2021 modifications of the approval. The Supreme Court stayed the rulings, granted certiorari, and unanimously reversed in FDA v. Alliance for Hippocratic Medicine (June 2024) on the ground that the medical-association plaintiffs lacked Article III standing because they could not demonstrate any individualized injury. The case is the central recent example of the venue-selection-and-nationwide-injunction dynamic. Case study 02 walks through it in detail.

The Trump 2024 federal prosecutions. Two federal criminal cases against former (and at the time of indictment) presidential candidate Donald Trump moved through the lower federal courts during 2023 and 2024: the documents case in the Southern District of Florida (Judge Aileen Cannon, Trump appointee) and the January 6 case in the District of Columbia (Judge Tanya Chutkan, Obama appointee). Both cases produced novel rulings on presidential immunity and on the scope of Special Counsel authority. The Supreme Court intervened in Trump v. United States (July 2024), holding that former presidents have presumptive immunity for official acts and absolute immunity for "core" constitutional functions. The cases were affected by the November 2024 election and were dismissed by the Department of Justice in early 2025 following Trump's reelection, in keeping with the Department's longstanding position that a sitting president cannot be criminally prosecuted. Whatever one's views of the prosecutions, the institutional point is that two district judges of opposite-party appointments produced rulings that the Supreme Court substantially modified — a reminder that the lower federal courts and the Supreme Court are in continual interaction.

Student loan litigation (2022–2024). The Biden administration's student-loan-forgiveness orders (originally announced in August 2022) were challenged in multiple federal district courts. The Eastern District of Missouri ruled against the program; the Fifth Circuit affirmed; the Supreme Court reviewed and held in Biden v. Nebraska (June 2023) that the HEROES Act did not authorize the mass loan-discharge program. The administration then pursued alternative regulatory pathways, which were also challenged in district court and partially enjoined. The pattern — major-questions-doctrine-type cases reaching the Supreme Court via the lower courts, with the lower-court venue and panel composition mattering greatly to the timing and shape of relief — is recurring under both administrations.

State election-administration challenges (2020–2024). Federal lawsuits over state election rules — voter-ID laws, registration deadlines, mail-ballot procedures, drop-box availability, signature-verification standards — number in the dozens every election cycle. Most originate in federal district courts of the affected states, are appealed to the relevant circuit, and may or may not reach the Supreme Court. The 2020 election produced a wave of post-election challenges, almost all of which were rejected by federal district courts on standing or merits grounds; the lower courts' uniform rejection of those challenges, often by Republican-appointed judges, was a significant institutional fact about the integrity of the federal judicial process under stress. (We return to this in chapter 37, "Democratic Erosion.") The 2024 cycle produced its own wave of pre-election and post-election lawsuits, with similar patterns of rejection.

Title IX and gender-identity rules. The Department of Education's 2024 Title IX rule on protections for LGBTQ students was challenged in multiple federal district courts. Different districts produced different injunctions covering different sets of states; one nationwide injunction was issued and partially modified on appeal. Whatever one's views of the underlying rule, the litigation pattern — a single regulation, multiple lawsuits in different districts, inconsistent injunctions, uncertainty about which states the rule applies in — is a vivid illustration of why the nationwide-injunction debate matters. Citizens, schools, and state agencies in 2024 had to navigate a regulatory environment in which the legal status of a federal rule depended on which federal district they happened to be in.

Trump-2 administration challenges (2025–2026). As of this textbook's revision, federal district courts have already ruled on early Trump-2 executive orders concerning birthright citizenship, federal grants and contracting, executive-branch personnel restructuring, and immigration enforcement. The pattern from the Trump-1 years — district-court injunctions in Democratic-leaning districts (the District of Columbia, the Northern District of California, the District of Massachusetts), accelerated emergency-stay applications to the Supreme Court — has resumed. The structural dynamics are the same; the policies are different. A reader who has internalized the lessons of this chapter should be able to predict, in rough outline, how a litigation challenge to any contemporary federal policy will move through the system.

The list could be substantially longer; these examples are meant to be representative, not exhaustive. The shared institutional point is that when federal policy is contested, federal district courts — selected by the litigants, in venues chosen for their expected receptivity — are the first stop. The circuits are the second stop. The Supreme Court is the third, and it filters heavily: of the hundreds of federal-policy challenges filed every year, only a handful reach merits review at One First Street.

13.9 The Day-to-Day: What Federal Judging Looks Like

It is easy to read political-science writing about the federal courts and conclude that federal judging is mostly about high-stakes constitutional decisions. Almost none of it is.

A federal district judge in a midsized district might in a single week:

• Conduct a sentencing hearing in a multi-defendant fentanyl-distribution case.
• Hold a pretrial conference in a civil-rights case challenging a county jail's medical-care policies.
• Rule on cross-motions for summary judgment in a sex-discrimination case under Title VII.
• Sign forty routine orders extending discovery deadlines, granting unopposed motions, approving stipulated protective orders.
• Conduct a guilty-plea colloquy in a wire-fraud case (the colloquy ensures the plea is knowing and voluntary).
• Hold a competency hearing in a federal kidnapping prosecution.
• Issue a written opinion denying a motion to suppress in a Fourth Amendment case.
• Conduct a settlement conference in a contract dispute between two corporations.
• Hold an evidentiary hearing on a habeas petition by a federal prisoner.

None of these are constitutional landmarks. All of them are federal-law-and-American-life moments. The judges who do this work for fifteen, twenty, thirty years do not typically appear on cable news. They are nevertheless among the most consequential public officials in the country, in the aggregate.

Two specific features of the day-to-day docket are worth a closer look.

13.9.1 Plea bargaining and the criminal docket

Federal prosecutors charge — and federal grand juries indict — about 75,000 criminal cases per year. Of those, roughly 95 to 97 percent are resolved by guilty plea, not by trial. The federal criminal trial is a rare event in most districts.

The dominance of plea bargaining is structural: federal sentencing exposure is high, the federal Sentencing Guidelines (advisory after Booker) still anchor sentencing ranges, and the post-Booker practice of acceptance-of-responsibility reductions creates a substantial differential between the sentence on a plea and the sentence after conviction at trial. The "trial penalty" — the difference in sentence between a defendant who pleads and a defendant who exercises the constitutional right to trial and is convicted — is empirically large. Critics across the ideological spectrum (the Cato Institute, the National Association of Criminal Defense Lawyers, the American Bar Association, the National District Attorneys Association in measured form) have argued that the trial penalty is too high and pressures defendants into pleas.

Defenders of the plea system point out that without plea bargaining, the federal docket would collapse — a system that tried 95 percent of the cases it currently disposes of by plea would require ten times the courtrooms and judges. The federal criminal-justice system is, structurally, a plea-bargaining system with a small trial appendage.

13.9.2 Sentencing after Booker

In United States v. Booker (2005), the Supreme Court held that the U.S. Sentencing Guidelines, which had been mandatory since the Sentencing Reform Act of 1984, were unconstitutional in their mandatory form because they allowed a judge (rather than a jury) to find facts that increased the sentencing range. The Court's remedy was to make the Guidelines advisory: judges still calculate the Guidelines range, but they are not required to sentence within it.

The post-Booker practice has been uneven. In some districts, judges sentence within the Guidelines in the substantial majority of cases. In others, downward variances (sentences below the Guidelines range) are common. The First Step Act of 2018 introduced bipartisan sentencing reforms, including retroactive application of the Fair Sentencing Act of 2010's reduction in crack-cocaine sentencing disparities.

Sentencing has become, in many ways, the single most consequential discretionary decision an Article III judge makes routinely. A judge sentencing a defendant on a drug-distribution conviction has discretion that can mean the difference between a five-year sentence and a fifteen-year sentence — a discretion that is constrained by Guidelines and statutory mandatory minimums but, after Booker, is genuinely substantial. The variation across districts and across judges has been studied extensively (the Sentencing Commission publishes annual data) and is a major area of empirical legal scholarship.

13.10 The Lower Courts and the Rule of Law

We close with a question that has been latent throughout this chapter: what is the role of the lower federal courts in maintaining the rule of law in the United States?

Three observations.

First, the lower federal courts are the primary mechanism by which constitutional rights are vindicated for individual Americans. The Supreme Court hears sixty cases a year. The Supreme Court does not hear individual habeas petitions on the merits; it does not hear most civil-rights claims; it does not retry sentencing decisions. The rule of law for individual federal litigants is, in practice, lower-court rule of law.

Second, the lower federal courts are the institutional place where statutory and regulatory law is operationalized. When Congress passes a statute and an agency issues a rule, the day-to-day question of what the statute and the rule mean — in this factual context, against this objection, for this defendant — is answered by lower-court judges. The Supreme Court provides occasional clarification on systemic questions; the lower courts run the rest.

Third, the lower federal courts are the place where Supreme Court precedent gets stress-tested. When the Court issues a decision, the next decade of lower-court rulings tells us what the decision actually means. Brown v. Board in 1954 was operationalized, or not operationalized, by the lower federal courts of the South over the next twenty years (case study 01). Citizens United in 2010 was operationalized by lower-court rulings on disclosure, contribution limits, and coordination. Dobbs in 2022 has been operationalized — and continues to be — by lower-court rulings on standing, severability, and statutory implementation across more than thirty states.

The lower federal courts are, in this sense, the connective tissue between the Constitution and American life. Most Americans will never appear before the Supreme Court; many will, directly or indirectly, be affected by the work of a federal district judge or a federal magistrate or a federal court of appeals.

A democratic citizen who wants to understand how American government actually works needs to know what these courts are, who staffs them, how they decide what they decide, and where the institutional pressures on them come from. That is the project of this chapter.

The next chapter — Chapter 14 — turns to the Supreme Court itself. But you should now read that chapter knowing that the Court sits atop a vast lower-court system whose work it depends on. The Justices read the briefs that lower-court judges produced the records for. They cite the circuit rulings as the doctrinal trail. They review (or decline to review) the orders that lower courts entered. The Supreme Court is the apex of the federal judiciary — but the lower federal courts are most of the federal judiciary. Now you know where to look.

Looking ahead. Chapter 14 turns to the Supreme Court of the United States. We will examine the cert process, oral argument, conference and vote, opinion-writing, and the Roberts Court of 2026 in particular. Read it knowing what you now know about the lower courts: the cases the Court reviews come from the courts you have just learned about, and the doctrines the Court announces are operationalized by those courts in the years that follow.
