Every Key Decision

Blair sat on the court; the surviving evidence of exactly what each judge said is contested (the case was reported decades later from imperfect notes). Virginia's Court of Appeals asserted that courts could refuse to enforce legislative acts inconsistent with the constitution.

A direct state-court precursor to Marbury v. Madison, two decades early — though scholars caution that the record of Caton is murkier than the legend.

Cushing, as Chief Justice of Massachusetts, delivered the jury charge that abolished slavery in the state. Slavery is incompatible with the Massachusetts Constitution's declaration that "all men are born free and equal."

The first judicial abolition of slavery in American history. Rugg noted that the same "born free and equal" language appeared in Virginia's first constitution — and no Virginia court ever raised the question.

As a United States senator, Ellsworth was the principal draftsman. Created the federal district and circuit courts, fixed the size of the Supreme Court, and defined the jurisdiction of the federal judiciary — including the Section 25 power to review state-court judgments on questions of federal law.

The foundational statute of the federal court system, still the backbone of federal jurisdiction more than two centuries later.

Jay delivered the charge to the jury, telling them that while they should presume the judges were the best judges of law, "you have a right to take upon yourselves to judge of both, and to determine the law as well as the fact in controversy." After seriatim opinions on the injunction in 1792 (Jay wrote briefly), the case went to a jury trial before the full Supreme Court in 1794 — the only such trial in the Court's history.

The only jury trial ever conducted at the Supreme Court bar, and Jay's charge became a founding text in the long argument over jury nullification.

Johnson's lone written opinion as a justice — a procedural dissent. The Court granted an injunction concerning debts sequestered by Georgia during the Revolution.

The entirety of his Supreme Court paper trail: fourteen months, one dissent. His tenure is a case study in the early Court's structural dysfunction, not in jurisprudence.

Wilson and his circuit colleagues declined to perform non-judicial duties — an early assertion of separation of powers. Circuit courts (with Wilson among the judges) refused to act as pension commissioners subject to executive revision.

A precursor of judicial independence doctrine: federal judges may not be assigned duties subject to review by the other branches.

Jay, writing for the justices, politely refused Jefferson's request. The Supreme Court declined to give President Washington's cabinet an advisory opinion on twenty-nine questions of neutrality law.

Established the case-or-controversy principle that federal courts do not issue advisory opinions — a foundation of the separation of powers that has held for over two centuries.

Jay delivered the Court's unanimous decree. American admiralty courts — not French consuls sitting on American soil — have jurisdiction over prizes brought into U.S. ports.

A quiet but firm assertion of American judicial sovereignty during the Genet crisis: no foreign power would operate courts inside the United States.

Paterson presided, defining treason's scope in the young republic. Convictions of rebels for levying war against the United States.

The first major test of federal criminal authority against armed resistance.

One of the only decisions of Rutledge's brief August 1795 term as Chief Justice. The Court, under Chief Justice Rutledge, issued a prohibition against a federal district court exercising admiralty jurisdiction over a prize taken by a French privateer.

Rutledge's judicial record is almost entirely a record of absence: he resigned his associate seat before hearing a case, and his recess appointment as Chief lasted one term before the Senate rejected him. The significance is institutional — the first demonstration that the Senate's confirmation power is real.

Paterson's circuit charge is one of the era's fullest statements of judicial review before Marbury. A state statute inconsistent with the state constitution is void; property may not be taken without just compensation.

A cornerstone of pre-Marbury judicial review doctrine and an early articulation of constitutional property protections.

Chase wrote one of the seriatim opinions sustaining the tax. Congress's tax on carriages is an excise, not a 'direct tax' requiring apportionment among the states.

The Court weighed the constitutionality of an act of Congress seven years before Marbury — judicial review in practice before it had a name.

Chase wrote the leading seriatim opinion. The 1783 Treaty of Paris overrides Virginia's wartime confiscation of debts owed to British creditors; a national treaty prevails over conflicting state law.

The founding statement of treaty supremacy — argued and lost by John Marshall (§13), in his only appearance as an advocate before the Court he would later lead.

Ellsworth wrote for the Court. The Supreme Court's appellate jurisdiction and standard of review are defined by Congress; absent a statutory provision for reviewing facts, the Court is bound by the record below.

An early statement that the shape of federal appellate jurisdiction is Congress's to set — a principle of enduring importance.

Moore wrote a seriatim opinion — the only opinion of his Supreme Court tenure. France was an 'enemy' within the 1799 salvage act: the undeclared Quasi-War was a real war, though 'limited' and 'partial.'

Early authority that Congress may authorize a war without declaring one, still cited in war-powers debates.

Marshall wrote the opinion — while declining to issue the writ, avoiding a confrontation he could not win. The Court has the power to declare acts of Congress unconstitutional.

Judicial review. The single most important decision in the Court's history: "It is emphatically the province and duty of the judicial department to say what the law is."

Paterson wrote for the Court, six days after Marbury. Upheld Congress's repeal of the Judiciary Act of 1801 and the justices' circuit-riding duties.

The quiet companion to Marbury — the Court's strategic retreat that preserved its independence during the Jeffersonian assault on the judiciary.

Livingston, then a New York judge, dissented — he would have awarded the fox to the pursuing huntsman. Mere pursuit gives no property right in a wild animal; capture or mortal wounding does.

The first-possession chestnut that has opened Anglo-American property courses for two centuries; the majority's rule won, but Livingston's wit is why students remember the case.

Johnson concurred separately, resting on 'the reason and nature of things' rather than the Contract Clause — and voicing suspicion that the suit was feigned. Georgia could not revoke the corrupt Yazoo land grants once title had passed to innocent purchasers.

The first display of Johnson's independence in a landmark: agreeing with Marshall's (§13) result while refusing his reasoning.

Duvall dissented alone from Marshall's (§13) opinion. Hearsay evidence is inadmissible to prove a freedom-suit petitioner's descent from a free woman; the Queen family remained enslaved.

'It will be universally admitted that the right to freedom is more important than the right of property' — the lone dissent that redeems an otherwise silent tenure.

Story wrote for the Court. The Supreme Court has constitutional authority to review and reverse the decisions of state courts on questions of federal law.

Secured federal judicial supremacy over the states — a foundation stone of national union and of the Court's power.

Todd wrote for the Court — his first opinion, nine years after joining it. A land entry made within territory secured to the Cherokee by treaty was void under North Carolina's own entry laws and conveyed no title.

Western land law was nearly Todd's whole judicial output, and this was its opening statement: settlers could not claim what treaties had reserved.

Marshall wrote for a unanimous Court. Congress has implied powers under the Necessary and Proper Clause; states cannot tax federal instrumentalities.

"We must never forget that it is a constitution we are expounding." The foundation of implied federal power and of federal supremacy.

Livingston wrote for the Court. A slave ship brought into New Orleans was forfeit under the 1807 act barring the slave trade; a plea of distress did not excuse the voyage.

One of the early enforcement teeth of the federal slave-trade ban.

Livingston dissented alone: a capital crime, he insisted, must be defined by Congress itself. Congress may punish piracy 'as defined by the law of nations' without spelling out the definition in the statute.

A lonely early statement of legislative precision in capital cases — 'in a case affecting life, no apology can be necessary for expressing my dissent.'

Johnson wrote for the Court. The House of Representatives has an implied power to punish non-members for contempt, though imprisonment ends with adjournment.

Still the foundation of Congress's contempt power two centuries on.

Todd wrote for the Court. A Virginia military-warrant entry too vague for a later locator to find was void; in equity a claimant recovers on the strength of his own title.

One of the precision rules that brought order to the chaos of overlapping frontier claims.

Washington wrote the opinion for the circuit court in Pennsylvania. Article IV's Privileges and Immunities Clause protects a core of fundamental rights of citizenship — though New Jersey could still reserve its oyster fisheries to its own citizens.

His enumeration of 'fundamental' privileges became the most-quoted gloss on the clause, central to the framing debates of the Fourteenth Amendment.

Johnson wrote the circuit opinion — though the Judiciary Act left him unable to grant the sailor habeas relief. South Carolina's Negro Seamen Act, which jailed free Black sailors in Charleston harbor, was 'altogether irreconcilable' with the federal commerce power and treaty obligations.

An act of judicial courage delivered in Charleston itself; the state defied the ruling, rehearsing the nullification argument of the decade to come.

Washington wrote for the Court on rehearing. Kentucky's occupying-claimant laws violated the Virginia–Kentucky Compact of 1789, which the Contract Clause protects.

Extended the Contract Clause to interstate compacts — and set off years of Kentucky fury at the Court that shadowed Todd (§16) and Trimble (§20) at home.

Todd wrote for the Court. The contents of a lost or accidentally destroyed instrument may be proved by secondary evidence once its absence is honestly accounted for.

Still-good black-letter evidence law — quiet proof that Todd's craftsmanship outran his fame.

Thompson dissented alone. Maryland's license tax on importers fell as a duty on imports; goods in their 'original package' remain beyond state taxation.

His skepticism of the original-package doctrine anticipated the states'-rights commercial turn of the Taney (§24) years.

Trimble wrote for the Court. In the litigation's final decree, the surviving Africans not proven Spanish property were delivered to the United States — and freedom — while those adjudged Spanish property went to the claimants.

Closed the Court's most anguished slave-trade case; most of the survivors were resettled in Liberia.

Duvall wrote for the Court. A master's bequest of property to his slave works the slave's freedom by necessary implication.

Freed Nicholas Darnall — and stated a manumission principle that state courts drew on for decades.

Baldwin wrote for the Court. Spanish land grants made in Florida before the 1819 cession are property rights the treaty obliges the United States to respect.

His most substantial majority — the foundation of Florida land titles.

McLean wrote for the Court. There is no perpetual common-law copyright in published works; copyright in America is a creature of federal statute and its formalities.

The foundation of American copyright law — fittingly, a fight between two of the Court's own reporters.

Taney wrote for the Court in his first major opinion as Chief Justice. A legislative charter grants only what it expressly states; ambiguous grants are construed against private monopoly and in favor of the public interest.

A decisive turn away from Marshall's protection of vested corporate rights toward public power and economic competition — a foundational case in American property and corporate law.

Barbour wrote for the Court. New York could require masters of arriving ships to report their passengers: a police-power regulation of persons, not a regulation of commerce.

The Taney Court's opening statement on state power — 'persons are not the subject of commerce' — later repudiated by the Passenger Cases (1849) and Henderson v. New York (1876).

Thompson wrote for the Court. A federal court may issue mandamus compelling the Postmaster General to perform a purely ministerial duty.

The executive is not beyond judicial command — a cornerstone later generations reached for, from the steel-seizure case to the subpoena fights.

McKinley was the lone dissenter, adhering to his own circuit ruling that Taney's (§24) majority reversed. A corporation chartered in one state may contract and do business in another under interstate comity, unless the host state expressly forbids it.

The charter of interstate corporate enterprise in America — with McKinley cast as the last defender of state economic sovereignty.

Story wrote for the Court. Africans who seized the slave ship Amistad had been illegally enslaved and were free persons entitled to return home.

A landmark antislavery victory affirming that the illegal international slave trade could confer no legal title.

Story wrote for the Court. In commercial cases federal courts may apply a 'general' common law rather than the decisions of the state courts.

Governed the federal courts for nearly a century until overruled by Erie Railroad v. Tompkins (1938, Brandeis §67).

McKinley wrote for the Court. New states enter the Union on an equal footing with the original thirteen and take sovereign title to lands beneath their navigable waters.

The equal-footing doctrine — his one enduring majority, still the law of submerged lands.

Woodbury wrote for a unanimous Court, rejecting Salmon P. Chase's (§39) antislavery argument. The Fugitive Slave Act of 1793 was constitutional; an Ohio abolitionist was liable for harboring fugitives.

Slavery as one of the Constitution's 'sacred compromises' — the judicial settlement Uncle Tom's Cabin answered; Van Zandt became Stowe's Van Trompe.

Catron wrote two of the separate opinions. State licensing laws restricting liquor sales in Massachusetts, Rhode Island, and New Hampshire were upheld; six justices wrote seriatim with no opinion of the Court.

The muddled middle of the Taney Court's commerce doctrine — awaiting the synthesis Curtis (§32) would supply in Cooley.

Daniel wrote for the Court. A state's eminent domain power can take a chartered corporate franchise; compensation, not the Contract Clause, is the owner's protection.

The great counterweight to Dartmouth College: charters are property, and property yields to the sovereign on payment.

Woodbury agreed on the political question but dissented on martial law's reach. Which of Rhode Island's rival governments was legitimate is a political question for Congress, not the courts.

His partial dissent drew an early line against emergency power over individual rights.

Daniel dissented alone, holding to the English tidewater rule. Federal admiralty jurisdiction extends to the Great Lakes and navigable inland waters, not merely tidewater.

Taney's (§24) most nationalist opinion, with Daniel as the last agrarian holdout against commercial reality.

Grier presided with Judge Kane and charged the jury against constructive treason. Armed resistance to the Fugitive Slave Act at Christiana was riot or murder at most — not treason, which requires actually levying war.

The jury acquitted in minutes; the government abandoned some forty treason indictments, and constructive treason was finished in America.

Curtis wrote for the Court. Commerce subjects national in character demand exclusive congressional regulation; local subjects, like harbor pilotage, admit state regulation until Congress acts.

'Selective exclusiveness' — the foundation on which dormant-commerce doctrine still rests.

Daniel dissented, denying that a corporation could ever be a 'citizen.' A corporation's shareholders are presumed citizens of the chartering state, preserving corporate access to federal diversity jurisdiction.

The purest statement of his lifelong war on corporate access to the federal courts.

Taney wrote for a unanimous Court. State courts have no power to interfere with the federal courts or to free, on habeas corpus, a prisoner held under federal authority — here an abolitionist jailed under the Fugitive Slave Act.

A forceful assertion of federal judicial supremacy over the states — ironically deployed to enforce the Fugitive Slave Act.

Swayne wrote for the Court; Miller (§36) dissented. Municipal bonds valid under the state-court decisions in force when issued remain enforceable despite the state court's later reversal of doctrine.

'We shall never immolate truth, justice, and the law…' — the era's great bondholder-protection case and an early federal check on state judicial flip-flops.

Davis wrote for the Court; Chase (§39), with Wayne (§23), Swayne (§35), and Miller (§36), would have allowed Congress to authorize such tribunals. Military commissions may not try civilians where the civil courts are open and functioning.

'A law for rulers and people, equally in war and in peace' — the great charter of civilian supremacy, cited in every wartime civil-liberties fight since.

Wayne joined Field's (§38) five-justice majority, as in Cummings v. Missouri. The federal test oath barring former Confederates from law practice was an unconstitutional bill of attainder and ex post facto law.

The wartime Unionist drew his line at punitive Reconstruction.

Chase wrote for the Court. A federal court has no jurisdiction to enjoin the President from carrying out his official duties, including enforcing the Reconstruction Acts.

An early and enduring statement of the separation of powers and the limits of judicial control over the executive.

Chase wrote for the Court. The United States is 'an indestructible Union, composed of indestructible States'; the ordinances by which the Confederate states purported to secede were legally void.

The definitive judicial rejection of secession and a foundational statement on the permanence of the Union.

Chase wrote the opinion striking down the paper-money system he had helped create as Treasury secretary. The Legal Tender Acts making paper 'greenbacks' legal tender for pre-existing debts were unconstitutional.

A rare instance of a Chief Justice repudiating his own handiwork; reversed one year later in the Legal Tender Cases (1871) after the Court's membership grew.

Nelson wrote for the Court. Congress cannot tax the salary of a state judicial officer.

The cornerstone of intergovernmental tax immunity — good law for nearly seventy years until Graves v. New York (1939).

Woods wrote the circuit opinion sustaining an Enforcement Act indictment for Klan-style violence. The rights secured by the first eight amendments are privileges of national citizenship that Congress may protect — even against private conspiracies.

The high-water mark of Fourteenth Amendment interpretation in the nineteenth century — still quoted in incorporation debates.

Bradley concurred, joined by Swayne (§35) and Field (§38): woman's 'paramount destiny' is 'the noble and benign offices of wife and mother.' Admission to the bar is not a privilege of national citizenship; Illinois could refuse Myra Bradwell a law license.

The most-quoted statement of separate-spheres constitutionalism — the concurrence modern equal-protection law defines itself against.

Hunt presided as circuit justice, fined her $100, and declined to imprison her — blocking any appeal. Anthony was guilty of unlawful voting; Hunt directed the jury's verdict and refused to poll it.

The most notorious trial of the suffrage era: Anthony's courtroom speech became a founding text of the movement, and Hunt its foil.

Waite wrote for the Court. The Fourteenth Amendment restrains only state action, not private violence; the federal charges against the perpetrators of the Colfax Massacre could not stand.

Crippled federal enforcement of Black civil rights and helped usher in the era of racial terror and Jim Crow.

Hunt was the lone dissenter on the constitutional merits. The Enforcement Act's voting-protection sections exceeded the Fifteenth Amendment's warrant.

As the Court began dismantling Reconstruction's voting protections, the machine politician from Utica was the one justice who objected.

Field wrote for the Court. A state court cannot enter a binding personal judgment against a defendant outside its borders who was not served within the state.

The foundational decision on personal jurisdiction, still taught to every first-year law student.

Waite wrote for a unanimous Court. The Free Exercise Clause protects religious belief but not conduct; a religious duty is no defense to the federal ban on polygamy.

The first major free-exercise decision, and the origin of the belief-conduct distinction that still shapes religious-liberty law.

Strong wrote for the Court, as in the companion Ex parte Virginia. A statute excluding Black citizens from jury service violates the Equal Protection Clause.

The strongest equal-protection holdings of the nineteenth century — a floor that survived even the Jim Crow Court, in principle if rarely in practice.

Swayne wrote for a unanimous Court. The Civil War income tax was not a 'direct tax' requiring apportionment; direct taxes are capitations and taxes on land.

The income-tax precedent Pollock overturned fourteen years later — and the Sixteenth Amendment restored.

Woods wrote for the Court. The Ku Klux Act's criminal-conspiracy section was unconstitutional; the Fourteenth Amendment does not reach private violence.

The author of Hall dismantled Hall — federal protection against Klan terror ended by the judge who had once supplied it.

Gray wrote for the Court; Harlan (§44) dissented, joined by Woods (§45). A Native American born into a tribe is not 'subject to the jurisdiction' of the United States and gains no birthright citizenship.

The exclusionary reading of the Citizenship Clause — not undone for Native Americans until the Indian Citizenship Act of 1924.

Miller wrote for a unanimous Court. Congress may punish private violence against Black voters in federal elections.

The rare Gilded Age victory for federal enforcement — the Klan-era precedent voting-rights lawyers reached back to for a century.

Matthews wrote for the Court; Harlan (§44) dissented alone. Due process does not require states to charge felonies by grand-jury indictment.

Due process as evolving fundamental fairness — the framework, and the Harlan counter-position, that structured the incorporation debate into the 1960s.

Gray wrote for the Court; Field (§38) dissented alone. Congress may make Treasury notes legal tender in peacetime, as an incident of the borrowing and sovereign powers.

Closed the legal-tender wars for good — paper money as a permanent constitutional fact.

Bradley wrote the opinion. Compelling production of private papers to prove a charge violates the Fourth and Fifth Amendments.

The fountainhead of modern search-and-seizure and self-incrimination doctrine.

Woods wrote for the Court. The Second Amendment limits only the federal government; states may ban private armed parades.

The nineteenth-century baseline of Second Amendment law, undisturbed until the incorporation ruling in McDonald (2010).

Miller wrote for the Court. States may not regulate rates on interstate shipments, even for the portion within their borders.

Created the regulatory vacuum Congress filled within a year with the Interstate Commerce Act — the beginning of the federal administrative state.

Matthews wrote for a unanimous Court. A facially neutral ordinance administered 'with an evil eye and an unequal hand' denies equal protection — which extends to Chinese non-citizens.

The founding case of discriminatory-enforcement doctrine, and the era's clearest statement that the Constitution protects persons, not just citizens.

Lamar wrote for a unanimous Court. Manufacture is not commerce; Iowa could bar a distillery even though its entire output shipped interstate.

'Manufacture is transformation' — the production/commerce line that governed the commerce power from E.C. Knight to the New Deal.

Blatchford wrote for a 6–3 Court; Bradley (§41) in dissent said it practically overruled Munn. A rate scheme that makes commission-set rates final, with no judicial review of reasonableness, violates due process.

Opened the federal courts to rate-regulation review — the beginning of substantive due process in economic regulation.

Lamar dissented, joined by Chief Justice Fuller (§50): no statute authorized the protection, so habeas should not lie. The majority held a deputy marshal protecting Justice Field (§38) acted under federal authority and was immune from state murder charges.

An early marker in the debate over inherent executive power — the dissent insisting that authority must come from Congress.

Blatchford wrote for a 6–3 Court; Brewer (§51) dissented, with Field (§38) and Brown (§52). New York's legislatively fixed grain-elevator rates were constitutional, reaffirming Munn.

The counterweight to his own Chicago, Milwaukee opinion — regulation by legislature stands where regulation beyond review fell.

Brewer wrote for a unanimous Court. The contract-labor act did not reach a church's hiring of an English pastor; a statute's spirit controls its letter.

The classic citation for purposive statutory interpretation — and, for its 'Christian nation' passage, a permanent flashpoint.

Blatchford wrote for a unanimous Court. The Fifth Amendment privilege extends to grand-jury witnesses; an immunity statute must be as broad as the privilege.

Still the baseline of immunity law — every grant of witness immunity is measured against Counselman.

Shiras wrote for a 5–4 Court over dissents by Brewer (§51), Field (§38), Jackson (§54), and White (§55). North Dakota's grain-elevator rate regulation was constitutional under Munn and Budd.

Held the Munn line for regulation in the teeth of the era's laissez-faire tide.

Brewer wrote for a unanimous Court. The federal courts could enjoin the Pullman strike and jail Eugene Debs for contempt; the government may protect interstate commerce and the mails in equity.

The charter of the labor injunction — organized labor's chief legal grievance until the Norris–LaGuardia Act of 1932.

Fuller wrote for the Court. The Sherman Antitrust Act does not reach a sugar-refining monopoly, because manufacturing is not interstate 'commerce.'

Crippled early antitrust enforcement and exemplified the narrow commerce doctrine later swept away by the New Deal Court.

Shiras wrote the opinion. Congress may not impose imprisonment at hard labor on aliens without a judicial trial; the Fifth and Sixth Amendments protect all persons.

A rare exclusion-era vindication of aliens' constitutional rights — decided the same term as Plessy.

Peckham wrote for a unanimous Court. The Fourteenth Amendment's 'liberty' includes freedom of contract; Louisiana's insurance restriction fell.

The first liberty-of-contract strike-down — the doctrinal seed of the Lochner era.

Brown wrote for the Court; Brewer (§51) and Peckham (§56) dissented. Utah's eight-hour law for miners and smeltermen was a valid police-power protection of workers in dangerous trades.

The pre-Lochner path not taken — protective labor legislation sustained, seven years before the bakers' case.

Gray wrote the 6–2 majority; Fuller (§50) dissented, with Harlan (§44). A child born in the United States to Chinese immigrant parents is a citizen at birth under the Fourteenth Amendment.

The foundation of American birthright citizenship — decided at the height of Chinese exclusion, against the political wind.

Brown announced the judgment for a fractured 5–4 Court; the 'incorporation' doctrine came from White's (§55) concurrence. Puerto Rico was not 'part of the United States' for the Constitution's uniformity clause.

The keystone Insular Case — the Constitution does not follow the flag, a regime still governing the territories today.

Peckham wrote the opinion; Harlan (§44) dissented. Federal courts may enjoin state officers from enforcing unconstitutional state laws, sovereign immunity notwithstanding.

The procedural engine of constitutional litigation ever since — every suit against a state officer runs through Young.

Moody wrote a substantial dissent defending the commerce power. The Court struck the 1906 federal railroad-injury act, 5–4, as reaching employees outside interstate commerce.

Congress promptly re-enacted the statute on Moody's terms — the FELA that still governs railroad injuries today.

Fuller wrote for the Court. A union boycott in restraint of interstate trade violates the Sherman Antitrust Act, exposing union members to treble damages.

Turned antitrust law against organized labor — a blow to the union movement until Congress responded with the Clayton Act.

Brewer wrote for a unanimous Court, crediting Louis Brandeis's (§67) data-laden brief by name. Oregon's ten-hour law for women in laundries was constitutional, Lochner notwithstanding.

The 'Brandeis brief' enters constitutional law — social science as legal argument, from the Court's staunchest conservative.

Moody wrote the 8–1 majority; Harlan (§44) dissented alone. The Fifth Amendment self-incrimination privilege does not apply against the states through the Fourteenth Amendment.

Its framework for what due process absorbs steered incorporation doctrine until Malloy v. Hogan (1964) overruled it.

McKenna wrote for a short-handed Court, 4–2, over dissents by White (§55) and Holmes (§58). The Philippine cadena punishment was cruel and unusual; the Eighth Amendment is progressive, not frozen at 1791.

The origin of 'evolving standards' Eighth Amendment law — quoted in every modern punishment case from Trop to the death-penalty docket.

Lurton wrote for the Court, 7–2. Congress cannot bind a new state's choice of its own capital as a condition of admission; new states enter equal in sovereignty.

The classic statement of the equal-footing doctrine — Oklahoma moved its capital, and the Union stayed a union of equals.

Lamar wrote for a unanimous Court. The contempt sentences against Gompers and his AFL colleagues were set aside on procedural grounds, while the injunction power over the boycott stood.

Spared the labor movement's leaders jail while preserving the weapon used against them — the era's labor settlement in miniature.

White wrote for the Court, announcing the 'rule of reason.' The Sherman Antitrust Act prohibits only 'unreasonable' restraints of trade; the Standard Oil monopoly is one, and must be dissolved.

Broke up the era's greatest trust while establishing the reasonableness standard that still governs American antitrust law.

Lurton wrote for the Court. The combination controlling all rail terminal facilities at St. Louis violated the Sherman Act unless opened to every carrier on equal terms.

The seed of the essential-facilities doctrine in antitrust law.

McKenna wrote for a unanimous Court. The Mann Act was constitutional; Congress may bar interstate transportation for immoral purposes.

With Hipolite Egg, the commerce clause as national police power — the doctrinal road the New Deal later widened.

Day wrote for a unanimous Court. Evidence seized from a home without a warrant must be excluded from a federal prosecution.

The birth of the exclusionary rule — extended to the states in Mapp v. Ohio nearly a half-century later.

Pitney wrote the 6–3 majority; Holmes (§58) dissented alone, Day (§59) with Hughes (§62). A state may not forbid employers to condition employment on staying out of a union; liberty of contract protects the yellow-dog contract.

The constitutional shield of the anti-union workplace until the New Deal cases dissolved it.

Pitney wrote the 7–2 majority; Holmes (§58) and Hughes (§62) dissented. Leo Frank's mob-shadowed trial did not entitle him to federal habeas relief; state corrective process sufficed.

Eight years later Moore v. Dempsey adopted the dissent, founding modern federal habeas review — Frank himself had been lynched within months.

White wrote for the Court. Oklahoma's 'grandfather clause,' exempting from a literacy test those whose ancestors could vote before 1866, is an unconstitutional evasion of the Fifteenth Amendment.

A rare Fifteenth Amendment victory in the Jim Crow era, striking one of the devices used to disenfranchise Black voters.

Lamar wrote for the majority; Day (§59) dissented. The President could withdraw public oil lands from private claim; long executive practice with congressional acquiescence implies authority.

'Government is a practical affair' — a cornerstone of implied executive power, cited from the steel seizure to modern emergencies.

Day wrote for a unanimous Court. Louisville's block-by-block residential segregation ordinance violated Fourteenth Amendment due process.

Framed as property rights rather than racial equality — but it stopped the spread of segregation-by-ordinance at the height of Jim Crow.

Pitney wrote the 5–4 majority, as he had the unanimous New York Central v. White for New York's scheme weeks earlier. Washington's compulsory state-fund workers' compensation system was constitutional.

The author of Coppage secured the workmen's-compensation revolution — the era's alignments were never simple.

Day wrote the 5–4 majority; Holmes (§58) dissented, joined by McKenna (§57), Brandeis (§67), and Clarke (§68). The federal child-labor act exceeded the commerce power; regulation of production belongs to the states.

The high wall of dual federalism — and the target of one of Holmes's greatest dissents — until United States v. Darby leveled it in 1941.

White wrote for a unanimous Court. The military draft for the First World War is a constitutional exercise of Congress's power to raise armies and does not impose 'involuntary servitude.'

Settled the constitutionality of conscription — the legal foundation for the draft in every subsequent war.

Holmes wrote for a unanimous Court, coining the phrase and the 'shouting fire in a theatre' image. Speech creating a 'clear and present danger' of harms Congress may prevent — such as obstructing wartime conscription — is not protected.

The origin of the 'clear and present danger' test and the starting point of modern First Amendment law.

Van Devanter wrote for the Court, 7–2; Holmes (§58) dissented, joined by Brandeis (§67). Applying the income tax to a sitting federal judge's salary unconstitutionally diminishes judicial compensation.

The high-water mark of judicial-compensation protection, pared back in 1939 and formally overruled in United States v. Hatter (2001).

Pitney wrote the 6–3 majority; Brandeis (§67) dissented, with Holmes (§58) and Clarke (§68). The Clayton Act's labor provisions do not shield secondary boycotts from federal injunction.

Kept the labor injunction alive for another decade, until Norris–LaGuardia (1932).

Taft wrote for the Court. Congress cannot use its taxing power as a pretext to regulate matters — here, child labor — reserved to the states.

Part of the pre-New Deal line limiting federal power over the economy; effectively overtaken after 1937.

Sutherland wrote the majority; Taft (§69), joined by Sanford (§72), and Holmes (§58) dissented. The District of Columbia's minimum wage for women violated liberty of contract.

The doctrinal peak of liberty of contract — overruled by West Coast Hotel in 1937, over Sutherland's own dissent.

McReynolds wrote the 7–2 majority; Holmes (§58) dissented. Nebraska's ban on teaching modern foreign languages violated Fourteenth Amendment liberty.

Liberty 'to marry, establish a home and bring up children' — the wellspring of substantive-liberty doctrine from Griswold to Obergefell.

Sanford wrote the 7–2 majority; Holmes (§58) and Brandeis (§67) dissented. Gitlow's conviction stood — but the Court assumed that First Amendment speech and press liberties bind the states through the Fourteenth Amendment.

The assumption became the incorporation doctrine — nearly every liberty Americans hold against their states traces to this sentence.

McReynolds wrote for a unanimous Court. Oregon's compulsory public-school law unconstitutionally interfered with parents' control of their children's education.

'The child is not the mere creature of the State' — the charter of educational liberty and of every school-choice argument since.

Taft, drawing on his own experience as President, wrote for the Court. The President has the constitutional power to remove executive officers he has appointed, without the Senate's consent.

A foundational and still-contested decision on presidential control of the executive branch, central to modern separation-of-powers disputes.

Sutherland wrote the 6–3 majority, over the silent dissents of his fellow Horsemen. Comprehensive municipal zoning is a valid exercise of the police power.

The constitutional foundation of every zoning code in America — written by the Court's arch-conservative.

Sanford wrote for a unanimous Court. Kansas's criminal-syndicalism act, as applied to an organizer with no evidence of advocacy of violence, denied due process.

The first Supreme Court victory for a free-speech claimant against a state.

Van Devanter wrote for a unanimous Court in the Senate's Teapot Dome-era probe of the Justice Department. Congress has implied power to compel private persons to testify in aid of its legislative function.

The foundation of congressional investigative power — cited in every subpoena battle from Watergate to the present.

Butler wrote the 6–3 majority; Holmes (§58) dissented — 'freedom for the thought that we hate.' A pacifist unwilling to promise to bear arms could be denied naturalization.

Overruled in 1946 — but immortal as the provocation for Holmes's final great dissent.

Hughes wrote for the Court. Government may almost never impose a prior restraint forbidding publication; a law authorizing courts to shut down 'malicious' newspapers is unconstitutional.

The foundational free-press decision against prior restraint, later decisive in the Pentagon Papers case.

Brandeis dissented. (Dissenting) A state may regulate entry into the ice business; a 'single courageous State may, if its citizens choose, serve as a laboratory' for social and economic experiment.

Coined the enduring idea of the states as 'laboratories of democracy,' a cornerstone of American federalism.

Sutherland wrote the 7–2 majority; Butler (§71) and McReynolds (§66) dissented. Due process required the effective appointment of counsel for the Scottsboro defendants in a capital case.

The beginning of the constitutional right to counsel — the road that leads to Gideon.

Roberts wrote the 5–4 majority over the Four Horsemen's dissent. New York's milk-price regulation was constitutional; price control is valid if reasonably related to public welfare.

The first crack in the old economic constitution — three years before the switch it foreshadowed.

McReynolds wrote the Horsemen's dissent — and reportedly declared from the bench that the Constitution 'as we have known it, is gone.' The 5–4 majority sustained the abrogation of gold clauses in private contracts.

The old order's cry of despair, delivered extemporaneously as the New Deal's monetary policy survived.

Butler wrote the majority. New York's minimum wage for women fell, 5–4, under Adkins.

Liberty of contract's last stand — overturned within a year by West Coast Hotel.

Roberts wrote the 6–3 majority; Stone (§73) answered that 'the only check upon our own exercise of power is our own sense of self-restraint.' The Agricultural Adjustment Act's processing tax invaded the states' reserved powers.

The 'T-square' passage became the standard citation for mechanical jurisprudence — usually by its critics.

Sutherland wrote the 7–1 majority. The arms-embargo delegation was valid; the President is the 'sole organ' of the nation in international relations.

The most-cited foundation of executive foreign-affairs power — its sweeping dicta debated in every war-powers and foreign-policy fight since.

Cardozo wrote for the Court. The old-age benefits program of the Social Security Act is a constitutional exercise of Congress's power to spend for the general welfare.

Upheld the heart of Social Security and the constitutional basis of the modern welfare state.

Hughes wrote for the Court. Congress may regulate labor relations in manufacturing under the Commerce Clause because industrial strife affects interstate commerce.

Upheld the Wagner Act and vastly expanded federal commerce power — a constitutional cornerstone of the New Deal order.

Cardozo wrote for the Court. Only those provisions of the Bill of Rights 'implicit in the concept of ordered liberty' apply against the states through the Fourteenth Amendment.

Set out the theory of 'selective incorporation' that governed which federal rights bind the states — the framework of incorporation doctrine for a generation.

Cardozo wrote for the Court. The federal-state unemployment compensation scheme financed by a payroll tax is constitutional.

Sustained the second pillar of Social Security, confirming Congress's broad power to tax and spend for social welfare.

Brandeis wrote for the Court, overruling Swift v. Tyson (1842, Story §18). In diversity cases federal courts must apply state law; 'there is no federal general common law.'

One of the most important decisions on the structure of the federal courts, reshaping the relationship between state and federal law.

Stone wrote for the Court, and wrote the footnote. Economic regulation is presumed constitutional — but the presumption may narrow for laws touching the political process or aimed at 'discrete and insular minorities' (the celebrated Footnote Four).

Footnote Four became the blueprint for modern civil-rights and civil-liberties law and the tiers of judicial scrutiny.

McReynolds wrote for a unanimous Court. A sawed-off shotgun, absent evidence of militia utility, is not protected by the Second Amendment.

The Supreme Court's only substantial Second Amendment holding for nearly seventy years, until Heller (2008).

Murphy wrote the 8–1 majority. Peaceful labor picketing is speech protected by the First Amendment.

Labor's great free-speech victory — the ex-governor who refused to break the Flint strike constitutionalized the picket line.

Byrnes wrote for a unanimous Court; Douglas (§79) and Jackson (§82) concurred on right-to-travel grounds. California's law criminalizing the transport of indigent migrants into the state violated the Commerce Clause.

The Depression's 'anti-Okie' laws fell — persons, Byrnes wrote, are not 'a moral pestilence' to be quarantined at state lines.

Stone wrote for a unanimous Court. Congress may set national wage and hour standards under the Commerce Clause; Hammer v. Dagenhart is overruled.

Completed the New Deal constitutional settlement, removing judicial barriers to federal economic regulation for decades.

Murphy wrote for a unanimous Court. 'Fighting words' — insults likely to provoke immediate violence — fall outside First Amendment protection.

Still the framework for every categorical exception to free speech — endlessly cited, steadily narrowed.

Douglas wrote for the Court. A law ordering the sterilization of certain repeat criminals violates equal protection; procreation is 'one of the basic civil rights of man.'

An early recognition of fundamental rights and heightened scrutiny, and a repudiation of the eugenic thinking of Buck v. Bell.

Rutledge wrote for the Court. Child-labor laws may be applied to a child distributing religious literature over a free-exercise objection.

'Parents may be free to become martyrs themselves. But it does not follow they are free… to make martyrs of their children' — still the touchstone for state power over children's welfare.

Reed wrote the 8–1 majority — reassigned from Frankfurter (§78) so a southern Protestant Democrat would speak for the Court. The Texas Democratic Party's whites-only primary violated the Fifteenth Amendment; Grovey v. Townsend was overruled.

The beginning of the end of the white primary — the first great modern voting-rights decision.

Rutledge wrote the 5–4 majority. Texas could not require union organizers to register before making an organizing speech.

The 'preferred position' of First Amendment freedoms — the phrase and the priority both trace here.

Reed wrote the 5–4 majority; Black (§76) answered with his total-incorporation dissent. The Fifth Amendment's self-incrimination privilege did not apply to the states through the Fourteenth Amendment.

The stage for the incorporation debate that consumed the next two decades — Reed's holding fell in Malloy v. Hogan (1964).

Vinson wrote for the Court (three justices recused). Judicial enforcement of a racially restrictive covenant is state action forbidden by the Equal Protection Clause.

Struck a major legal prop from residential segregation and prefigured the Court's turn against Jim Crow.

Burton wrote for a unanimous Court. Segregated railroad dining-car arrangements violated the Interstate Commerce Act.

Decided the same day as Sweatt and McLaurin — the 1950 trilogy that set the table for Brown.

Vinson wrote for a unanimous Court. A hastily created 'separate' Black law school was not equal to the University of Texas's, which the state must therefore integrate.

One of the graduate-education cases that undermined 'separate but equal' and set the stage for Brown v. Board of Education.

Minton wrote the 5–3 majority. A warrantless search of the arrestee's premises incident to a lawful arrest was reasonable under the Fourth Amendment.

Governed search-incident doctrine for two decades until Chimel v. California (1969) — and Frankfurter's (§78) dissent became the law.

Vinson wrote the plurality opinion. The First Amendment does not bar convicting Communist Party leaders under the Smith Act for conspiring to advocate the overthrow of the government.

The high-water mark of Cold War restrictions on political speech, later sharply narrowed as the 'clear and present danger' test gave way to stronger speech protections.

Minton wrote the 6–3 majority; Black (§76) and Douglas (§79) dissented. New York's Feinberg Law, barring members of listed subversive organizations from teaching, was upheld.

The high-water mark of loyalty-era deference — effectively overruled by Keyishian (1967), which made academic freedom 'a special concern of the First Amendment.'

Jackson's concurrence set out the famous three-tier framework for presidential power. (Concurring) The President lacked power to seize the steel mills; presidential authority is 'at its lowest ebb' when he acts against the will of Congress.

The single most influential opinion on the separation of powers, cited in virtually every modern dispute over executive authority.

Burton dissented, joined by Reed (§77): baseball was plainly interstate commerce. Baseball's judge-made antitrust exemption was reaffirmed, 7–2, on congressional inaction.

The dissent nearly every later court and commentator has sided with — the exemption survives as an acknowledged anomaly.

Harlan wrote for a unanimous Court. The state may not compel the NAACP to disclose its membership lists; freedom of association is protected by the First and Fourteenth Amendments.

Established the constitutional freedom of association, shielding civil-rights and other groups from state harassment.

Whittaker wrote the majority; Douglas (§79) dissented alone. An informant's tip, corroborated in detail by the arresting officer's own observations, supplies probable cause for a warrantless arrest.

Still a staple of probable-cause doctrine — his one securely remembered opinion.

Clark wrote the majority (6–3 in judgment, five justices on the Fourth Amendment holding). Evidence obtained by unconstitutional search and seizure is inadmissible in state court; Wolf v. Colorado overruled.

The criminal-procedure revolution's opening gun — the exclusionary rule nationalized.

Harlan dissented from the Court's refusal to reach the merits. (Dissenting) The Constitution's guarantee of 'liberty' is a 'rational continuum' protecting intimate personal decisions, including a married couple's use of contraceptives.

The intellectual foundation of the right to privacy soon adopted in Griswold (1965, Douglas §79), and a touchstone of substantive due process.

Black wrote for the Court. Official prayer composed for recitation in the public schools violates the Establishment Clause.

Removed state-sponsored prayer from public schools — one of the most controversial and enduring church-state rulings.

Clark wrote the 8–1 majority; Stewart (§92) dissented. School-sponsored Bible reading and prayer violate the Establishment Clause.

The secular purpose and primary-effect test — the core of establishment doctrine for the next half-century.

Black wrote for a unanimous Court, vindicating his own dissent from twenty years earlier. The Sixth Amendment right to counsel applies to the states; a poor defendant facing serious charges is entitled to a court-appointed lawyer.

Guaranteed legal representation to millions of indigent defendants — a pillar of modern criminal justice.

Goldberg wrote the majority. Automatically stripping citizenship for draft evasion is punishment that requires a criminal trial.

'While the Constitution protects against invasions of individual rights, it is not a suicide pact' — the balance-in-crisis line quoted ever since.

Goldberg wrote the 5–4 majority. Once an investigation focuses on a suspect in custody, denial of counsel during interrogation violates the Sixth Amendment.

The direct precursor of Miranda — the interrogation room's door opened to lawyers.

Clark wrote for a unanimous Court, as in the companion Katzenbach v. McClung. The Civil Rights Act's public-accommodations title was valid under the commerce power.

The constitutional green light for the Second Reconstruction, delivered by a Texan two months after the Act passed.

Stewart concurred: 'I know it when I see it, and the motion picture involved in this case is not that.' An Ohio obscenity conviction was reversed; only 'hard-core pornography' may be criminalized.

The most famous shrug in the U.S. Reports — candor about definition that doctrine never escaped.

Brennan wrote for the Court. A public official cannot recover for defamation without proving 'actual malice' — knowledge of falsity or reckless disregard for the truth.

Transformed American libel law and gave constitutional protection to robust, even erroneous, criticism of government — 'uninhibited, robust, and wide-open.'

Warren wrote for the Court; he called it the most important decision of his tenure. The Equal Protection Clause requires state legislative districts to be roughly equal in population — 'one person, one vote.'

Reordered representative government in every state, ending rural over-representation and reshaping American democracy.

Warren, a former prosecutor, wrote for the Court. Before custodial interrogation, police must warn suspects of their rights to silence and to counsel; statements taken without such warnings are inadmissible.

Made 'you have the right to remain silent' part of American life and the law of police interrogation.

Clark wrote the 8–1 majority. Massive, unrestrained pretrial and trial publicity denied Sam Sheppard due process.

The charter of fair-trial/free-press balance — trial judges must control the 'carnival atmosphere.'

Fortas wrote the majority. Juveniles facing delinquency proceedings are entitled to notice, counsel, confrontation, and the privilege against self-incrimination.

Due process reached the juvenile court — 'the condition of being a boy does not justify a kangaroo court.'

Stewart wrote the majority. Wiretapping a public phone booth is a Fourth Amendment search requiring a warrant.

'The Fourth Amendment protects people, not places' — the foundation of privacy doctrine in the electronic age.

Warren wrote for a unanimous Court. State laws banning interracial marriage violate the Equal Protection and Due Process Clauses.

Struck down anti-miscegenation laws nationwide and later became a cornerstone of the argument for marriage equality in Obergefell (§104).

Fortas wrote for the Court. Arkansas's ban on teaching evolution violated the Establishment Clause.

Scopes's ghost finally laid — the state may not tailor the curriculum to any religious doctrine.

Marshall wrote for the Court. The government may not criminalize the private possession of obscene material in one's own home.

A landmark of privacy and freedom of thought — 'a State has no business telling a man, sitting alone in his own house, what books he may read.'

Fortas wrote the majority. Students wearing black armbands against the Vietnam War engaged in protected speech; schools may punish only substantial disruption.

The schoolhouse-gate line — still the framework for every student-speech case.

Harlan wrote for the Court. A state may not punish the wearing of a jacket bearing an offensive antiwar slogan; 'one man's vulgarity is another's lyric.'

A cornerstone of free-speech law, protecting offensive and emotive expression from government censorship.

Burger wrote for the Court, creating the three-part 'Lemon test.' State aid to religious schools is unconstitutional unless it has a secular purpose, does not principally advance religion, and avoids 'excessive entanglement' with religion.

Governed Establishment Clause law for half a century before the Court abandoned it in 2022.

Burger wrote for a unanimous Court. Federal courts may order busing and other broad remedies to dismantle stubbornly segregated school systems.

Authorized the busing era of school desegregation, among the most consequential and contested remedies in civil-rights law.

Douglas dissented in a landmark of environmental thought. (Dissenting) Natural objects — valleys, rivers, trees — should have legal standing, through guardians, to sue for their own protection.

The most famous argument in American law for the 'rights of nature,' cited worldwide in environmental jurisprudence.

Burger wrote for a unanimous Court (Rehnquist §100 recused). Executive privilege is not absolute and must yield to the need for evidence in a criminal trial; the President must produce the subpoenaed Watergate tapes.

Reaffirmed that not even the President is above the law's demand for evidence; it forced Nixon's resignation.

Stewart announced the judgment in the joint lead opinion with Powell (§99) and Stevens (§101). Guided-discretion capital statutes are constitutional; the death penalty resumed.

With Furman, Stewart authored both poles of American capital-punishment law.

White wrote for the Court. A law is not unconstitutional under the Equal Protection Clause merely because it has a racially disproportionate impact; proof of discriminatory purpose is required.

One of the most consequential doctrines in equal-protection law, sharply limiting constitutional challenges to facially neutral policies.

Powell's solo controlling opinion held the balance on a Court split four to four. Rigid racial quotas in admissions are unconstitutional, but race may be considered as one factor among many in pursuit of a diverse student body.

His 'diversity' rationale became the law of university admissions from Bakke through Grutter (2003, O'Connor §102) until the Court rejected it in 2023.

Stevens wrote for the Court. When a statute is ambiguous, courts must defer to any reasonable interpretation by the agency that administers it.

For forty years the foundation of administrative law and the balance of power between courts and agencies, until overruled in Loper Bright Enterprises v. Raimondo (2024).

Powell wrote for the Court. Statistical evidence of systemwide racial disparity in capital sentencing does not prove unconstitutional discrimination in a particular case.

A pivotal death-penalty ruling; Powell later told his biographer it was the vote he would change.

Scalia dissented alone. (Dissenting) The independent-counsel law violates the separation of powers by stripping the President of control over executive functions; 'this wolf comes as a wolf.'

Derided at the time, his dissent's theory of the 'unitary executive' steadily gained force and is now widely regarded as vindicated.

Blackmun dissented. (Dissenting) The state's failure to protect a boy from a violent father — leaving him permanently brain-damaged — should not escape constitutional accountability. 'Poor Joshua!'

One of the most emotionally powerful dissents in the U.S. Reports, and a landmark in the debate over whether law should speak in the language of feeling.

Brennan wrote for the Court. Burning the American flag in political protest is expressive conduct protected by the First Amendment.

A powerful affirmation that government may not punish a symbol's desecration; it has withstood repeated efforts to overturn it by constitutional amendment.

Scalia wrote for the Court. A neutral, generally applicable law does not violate the Free Exercise Clause merely because it burdens a religious practice.

Sharply narrowed constitutional protection for religious exercise, prompting Congress to pass the Religious Freedom Restoration Act and igniting a debate that continues today.

Blackmun dissented alone, at the end of his career. (Dissenting from denial of certiorari) The death penalty cannot be administered consistently with the Constitution; 'I shall no longer tinker with the machinery of death.'

His final renunciation of capital punishment, joining Marshall (§96) and Brennan (§90) in categorical opposition.

Rehnquist wrote for the Court. Congress exceeded its commerce power in banning guns near schools; the Commerce Clause has judicially enforceable limits.

The first decision since 1937 to strike a federal statute as beyond the commerce power — the keystone of the modern federalism revival.

Ginsburg wrote for the Court. The state's exclusion of women from the Virginia Military Institute violates equal protection; sex-based classifications require an 'exceedingly persuasive justification.'

The capstone of the sex-equality revolution she had led as an advocate, near the high-water mark of constitutional protection against sex discrimination.

Rehnquist wrote for the Court. There is no constitutional right to physician-assisted suicide; substantive due process protects only rights deeply rooted in the nation's history and tradition.

A landmark limiting the expansion of unenumerated rights, central to modern due-process debates including Dobbs (§110).

Rehnquist, a longtime Miranda skeptic, wrote for the Court. Miranda v. Arizona is a constitutional rule that Congress cannot legislatively overrule.

A striking instance of institutional stewardship overriding a Chief Justice's own doctrinal instincts.

Breyer wrote the 5–4 majority. Nebraska's 'partial-birth abortion' ban, lacking a health exception, was unconstitutional.

The Casey framework applied at its edge — partially superseded by Gonzales v. Carhart (2007) after O'Connor's (§102) retirement.

O'Connor wrote for the Court, adding that she expected such preferences to be unnecessary within twenty-five years. A university may consider race as one factor in a holistic admissions process to achieve the educational benefits of diversity.

The high-water mark of affirmative action, embracing Powell's (§99) Bakke rationale, until the Court ended race-conscious admissions in 2023 — two decades ahead of her timetable.

Kennedy wrote for the Court, overruling Bowers v. Hardwick (1986, White §93). Laws criminalizing intimate conduct between adults of the same sex violate the liberty protected by the Due Process Clause.

The heart of the gay-rights revolution he authored, grounded in liberty and dignity rather than narrow doctrine.

O'Connor wrote the plurality opinion. A U.S. citizen detained as an enemy combatant is entitled to due process — notice and a meaningful chance to contest the detention. 'A state of war is not a blank check.'

A landmark check on executive power in the war on terror, insisting on the courts' role even in wartime.

Souter wrote the 5–4 majority. Courthouse Ten Commandments displays with a predominantly religious purpose violate the Establishment Clause.

The neutrality principle stated at full strength — decided the same day the Texas monument survived in Van Orden.

Ginsburg read her dissent aloud from the bench and called on Congress to act. (Dissenting) The majority's cramped reading of the deadline for pay-discrimination claims ignores how such discrimination actually works.

Congress responded with the Lilly Ledbetter Fair Pay Act of 2009 — a dissent that directly rewrote the law.

Breyer wrote the seventy-seven-page principal dissent, reading it from the bench. Voluntary race-conscious school-assignment plans in Seattle and Louisville were struck down.

'It is not often in the law that so few have so quickly changed so much' — his most impassioned moment on the bench.

Kennedy wrote for the Court. The First Amendment bars the government from restricting independent political spending by corporations and unions.

Transformed American campaign finance and remains among the most debated decisions of the era — the swing vote at its most conservative.

Roberts broke with the other conservatives to write the controlling opinion, saving the ACA. The Affordable Care Act's individual mandate exceeds Congress's commerce power but is valid as an exercise of the taxing power.

The defining act of his institutionalism — and, to critics, of result-driven reasoning.

Alito wrote for the Court. Closely held for-profit corporations with religious objections may opt out of the contraceptive-coverage requirement under the Religious Freedom Restoration Act.

A landmark of the modern religious-liberty expansion, extending conscience protections to businesses.

Sotomayor dissented from the bench. (Dissenting) 'The way to stop discrimination on the basis of race is to speak openly and candidly on the subject of race' — not to forbid its consideration.

Her direct answer to Chief Justice Roberts's (§109) colorblind formula, framing the argument the Court returned to in 2023.

Breyer dissented, joined by Ginsburg (§107), calling for full briefing on the death penalty's constitutionality. Oklahoma's lethal-injection protocol was upheld, 5–4.

'I believe it highly likely that the death penalty violates the Eighth Amendment' — the modern abolition argument, stated from the bench.

Kennedy wrote for a five-to-four Court. The Constitution guarantees same-sex couples the right to marry nationwide.

The culmination of a twenty-year arc, and one of the most consequential civil-rights rulings of the century.

Sotomayor dissented, in a passage that broke from the record into direct address. (Dissenting) Admitting evidence from an unlawful police stop because officers later found an outstanding warrant licenses exactly the arbitrary stops that fall hardest on communities of color.

Her most celebrated dissent, a landmark of the modern debate over policing and dignity.

Breyer wrote the 5–3 majority. Texas's admitting-privileges and surgical-center requirements imposed an undue burden and were struck down.

Undue-burden review with teeth — benefits weighed against burdens, evidence against assertion.

Kagan wrote for the Court. North Carolina unconstitutionally used race to draw two congressional districts.

A significant racial-gerrymandering precedent and a display of the craft beneath her reputation — building a cross-ideological majority on technical terrain.

Roberts wrote the controlling opinion, joining the liberals on the decisive point. The administration's stated reason for adding a citizenship question to the census 'appears to have been contrived' and cannot stand on this record.

A rare judicial check on executive rationale, and a clear example of Roberts's institutional caution.

Kavanaugh wrote for the Court. A prosecutor's repeated exclusion of Black jurors across six trials of the same defendant violated the Constitution.

A notable early majority, applying the rule against racial discrimination in jury selection.

Kagan wrote the dissent. (Dissenting) Partisan gerrymandering claims are justiciable and demand a remedy; 'for the first time in this Nation's history, the majority declares that it can do nothing.'

Her signature dissent, a passionate warning that the Court was leaving a proven constitutional wrong without remedy.

Gorsuch wrote the majority opinion. Title VII's prohibition on discrimination "because of sex" protects gay and transgender employees.

Textualism yielding a result that surprised textualism's political patrons — the clearest demonstration that Gorsuch follows the words, not the coalition.

Gorsuch wrote the majority, joined by the four liberals. The Creek Nation's reservation in eastern Oklahoma was never disestablished by Congress and remains Indian Country for federal criminal jurisdiction.

"On the far end of the Trail of Tears was a promise." If Congress wants to take something enormous away from a sovereign people, it must say so clearly — the size of the consequence does not loosen the clarity required of the text.

Kavanaugh concurred, setting out a framework for stare decisis. (Concurring) A criminal conviction requires a unanimous jury; a precedent should be overruled only after weighing how wrong it was, the reliance it created, and the consequences of keeping it.

His most substantial writing on when the Court should overrule precedent — a question at the heart of the modern Court.

Thomas wrote for the Court. Gun regulations are constitutional only if consistent with the nation's historical tradition of firearm regulation; New York's restrictive licensing scheme fails that test.

Remade Second Amendment litigation nationwide and marked the arrival of Thomas's long-held method at the center of the law.

Kagan wrote the dissent. (Dissenting) The 'major questions doctrine' wrongly strips agencies of authority Congress gave them, making the Court 'the decision-maker on climate policy.'

The leading liberal defense of the administrative state against the conservative Court's assault on agency power.

Jackson joined the majority and wrote a concurrence grounding the Voting Rights Act in the Fourteenth Amendment's original purpose. Alabama's congressional map likely violates the Voting Rights Act by diluting Black voting strength.

A surprising liberal victory preserving a core tool of the Voting Rights Act; Jackson's concurrence turned the originalist method toward racial justice.

Barrett pressed her own colleagues on method. (Concurring in part) History and tradition can inform but should not mechanically decide a constitutional question; courts also need workable principles.

Evidence of a justice thinking hard about how originalism should actually operate — willing to challenge Thomas (§106) and the majority on it.

Roberts wrote the majority; Gorsuch's 25-page concurrence traced delegated-power doctrine from English corporate charters (Kirk v. Nowill, 1786) through 19th-century railroad commissions — and chided Barrett's concurrence for intellectual imprecision. IEEPA does not authorize the President to impose tariffs.

A landmark separation-of-powers ruling against the defining policy of the president who appointed him. The concurrence argues the major questions doctrine is not a judicial invention but a restoration of principles the common law always applied to extraordinary delegations — Article I's last defense against executive accumulation.
