Path to the Supreme Court

Samuel Freeman Miller practiced medicine for a decade in Kentucky — an M.D. from Transylvania — before the law and antislavery conviction carried him to Keokuk, Iowa. Lincoln nominated the frontier lawyer on July 16, 1862, and the Senate confirmed him within half an hour: the first justice from west of the Mississippi. Over twenty-eight years and some six hundred opinions he became the dominant figure of the Chase and Waite Courts, and was seriously pushed for Chief Justice in 1873.

On the Supreme Court

Miller wrote the opinion that set the Fourteenth Amendment's course: Slaughter-House read the Privileges or Immunities Clause down to nearly nothing five years after ratification, and Reconstruction constitutionalism never fully recovered — the ruling is still relitigated every time the clause is invoked. The rest of the ledger is formidable in both directions: Bradwell v. Illinois let states bar women from the practice of law; Loan Association v. Topeka voided taxes raised for private benefit; Ex parte Yarbrough — nearly alone among the era's cases — sustained federal power to punish Klan violence against Black voters; and Wabash struck down state regulation of interstate rates, summoning the Interstate Commerce Commission into existence. He died in harness in October 1890: the strongest judicial mind of his generation, and the author of its most consequential retreat.

The Voting Record

No breakdown by subject is shown here. The Supreme Court Database sorts cases into categories — criminal procedure, economic activity, federalism — that were designed for the modern Court and, by the database’s own account, fitted to eighteenth- and nineteenth-century decisions as best it could afterwards. The overall figures above rest only on whether each vote was coded liberal or conservative, which is the same judgment in every era. The subject bars would not be.

Across the whole career Miller voted with Waite more than with anyone else — the same side of the judgment in 66.3% of their 326 divided cases — and with Clifford least, at 48.5%. See this Court →Compared against the 6 colleagues Miller shared at least 300 divided cases with.

Key Decisions

Slaughter-House Cases

1873

Holding · The Fourteenth Amendment's Privileges or Immunities Clause protects only rights of national citizenship, narrowly conceived; Louisiana's slaughterhouse monopoly stood.

Role · Miller wrote the 5–4 majority over dissents by Field (§38), Bradley (§41), and Swayne (§35).

The decision that hollowed the amendment's central clause within five years of its ratification — the fork in the road of Reconstruction constitutionalism.

Loan Association v. Topeka

1874

Holding · Taxation must serve a public purpose; municipal bonds issued to subsidize a private manufacturer were void.

Role · Miller wrote for the Court; Clifford (§34) dissented alone.

The public-purpose doctrine — judicial limits on the fiscal favors of the subsidy age.

Ex parte Yarbrough

1884

Holding · Congress may punish private violence against Black voters in federal elections.

Role · Miller wrote for a unanimous Court.

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

Wabash, St. Louis & Pacific Railway v. Illinois

1886

Holding · States may not regulate rates on interstate shipments, even for the portion within their borders.

Role · Miller wrote for the Court.

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

◆ Best Biography

Samuel Miller is a rarity among Reconstruction-era justices: a man with not one but two real biographies. Start with Michael A. Ross's Justice of Shattered Dreams (LSU Press, 2003), the modern, readable life that frames Miller as a self-made free-labor Republican whose Civil War hopes for the Court were, in the end, shattered. Then turn to the monument — Charles Fairman's Mr. Justice Miller and the Supreme Court, 1862–1890 (Harvard, 1939), still the definitive account and a landmark of Supreme Court historiography in its own right.

The Bookshelf

Best Place to Start

The modern biography and the natural first read — the first full life of Miller in over sixty years. Ross recovers him as a self-made free-labor Republican: the Kentucky physician who taught himself law, left a slaveholding state for free-soil Iowa, and reached the Court in 1862 as an intellectual force with no prior judicial experience. Ross's argument is that Miller's disappointments — with Reconstruction, and with a Court that would not go as far as he had hoped — are the key to the man, and that even the narrow Slaughter-House majority flows from a coherent free-labor constitutionalism rather than a betrayal of it. LSU Press, Conflicting Worlds series; 323 pp.

The Standard Biography

The monument, and still unsurpassed. Fairman's 1939 book is not only the definitive account of Miller — built on the justice's own candid letters to his Galveston kinsman William Pitt Ballinger — but one of the founding works of modern Supreme Court historiography, the book that showed a justice's life could be written as serious institutional history. Where Ross gives you the readable modern life, Fairman gives you the whole Court across Miller's twenty-eight years, opinion by opinion. Harvard University Press, viii + 456 pp.; reprinted by the Lawbook Exchange (2003).

The Pivotal Opinion

Miller's one indispensable opinion, and among the most consequential — and contested — in the Court's history. For a 5–4 majority he read the new Fourteenth Amendment narrowly, holding that its privileges-or-immunities clause protected only the rights of national citizenship and left the great body of civil rights where they had always been, with the states. He meant to guard the federal balance; the unintended legacy was an amendment left too weak to protect the freedpeople it was written for. Swayne (§35) and Field dissented; John Archibald Campbell (§33) had argued the losing broad reading at the bar. History has drifted toward the dissenters. Free online.

The Reconstruction Court

Three decades after the biography, Fairman returned to Miller's Court on the largest possible canvas — the standing institutional frame for this site from Clifford forward. Here Miller is no longer the sole subject but the dominant presence: the legal-tender wars, the habeas and Reconstruction-statute docket, and the Slaughter-House term all set in their full setting. Between the 1939 life and these volumes, no justice of the era has been more completely served by a single scholar. Macmillan; vol. 6 (1971), vol. 7 completed 1987.

The Great Opinion

The definitive study of Miller's most consequential opinion — the 1873 decision that first construed the Fourteenth Amendment and narrowed it for a century. Reviewers treat it and Ross's biography as the paired core of the modern Miller literature; it also appears on Campbell's shelf, for the man who argued the other side. University Press of Kansas.

The Reference Entry

The standard modern biographical encyclopedia of the Court: a signed essay on each of the 110 justices from Jay to Alito, alphabetically arranged, by a named scholar or journalist. Length tracks reputation — two pages for Thomas Johnson, three for Woods, eleven for Holmes — which is itself a rough map of who the literature has bothered with. It is not a substitute for a biography, and for the justices who have never had one it is often the most careful short account in print. Borrow it free at the Internet Archive.

The Reference Entry
The Oxford Companion to the Supreme Court of the United States
(2nd ed., 2005) by Hall, Kermit L., et al., eds.

The one-volume reference on the Court: more than a thousand signed entries on cases, doctrines, institutions and the justices, current to 2005. Cases and people share one alphabet, so a citation can be followed without changing volumes, and the biographical entries are short, written by specialists, and better than a longer sketch at carrying the historiography — what the argument about a justice currently is.

Ideas for Further Research

  • The self-made intellect of the post-war Court. A Kentucky doctor (Transylvania M.D., 1838) who taught himself law at thirty-one, left a slaveholding state for free-soil Keokuk, Iowa, and reached the Court in 1862 with no prior judicial experience — then became the justice contemporaries and historians alike rank as the dominant mind of the Reconstruction bench. He took his seat on July 21, 1862, in Peter Daniel's old chair (§28).
  • Slaughter-House and the Fourteenth Amendment's road not taken — the thread that carries the Gilded era. Miller wrote the 5–4 majority (1873) that narrowed the amendment; Swayne (§35) called the rival reading "a new Magna Charta" in dissent; Campbell (§33) argued that broad reading at the bar and lost. The enduring puzzle — pressed hardest by Ross — is how an antislavery free-labor Republican came to write the opinion later used to hollow out Reconstruction, and whether that was betrayal or principled federalism.
  • Twice almost Chief Justice — and the making of a biographical monument. Miller was seriously in contention for the center chair in 1864 (Chase got it) and again in the messy 1874 vacancy that runs through the Failed Nominations list before Waite. He is also the rare Reconstruction justice with two full biographies, the elder of them — Fairman 1939 — a landmark that helped invent the modern judicial biography. A redemption-and-ambition cousin to Swayne (§35), but with the record to justify the ambition.
