Mahlon Pitney is the New Jersey justice caught between two centuries. Taft's last appointment, a former congressman and state chief justice named in 1912, he is remembered — when he is remembered — as an enemy of organized labor, the author of Coppage v. Kansas, which struck down a ban on 'yellow-dog' contracts. Yet the same justice wrote the opinions upholding the first workers'-compensation laws, a paradox that makes him harder to place than his reputation allows. He has no full biography. Approach him through the Friedman & Israel chapter, the two lines of cases that define him, and the White Court histories.
The Bookshelf
The fullest life of a genuinely forgotten justice. The Chelsea House chapter recovers the New Jersey career — congressman, state senator, chief justice of the state supreme court — and the ten years in Washington, where a hardworking, unglamorous Pitney wrote steadily on labor, taxation, and procedure. It is honest about the reputation that has stuck to him, as labor's enemy, and honest too about the complication: that the author of Coppage also upheld workers' compensation. The starting point for a justice the literature otherwise skips.
The opinion that fixed Pitney's reputation. Kansas had made it a crime for an employer to require workers to promise not to join a union — the so-called 'yellow-dog' contract. Pitney, for the Court, struck the law down as a violation of liberty of contract, extending Lochner-era doctrine deep into labor relations; Holmes and Day dissented. For a generation Coppage was a chief obstacle to union organizing, undone only by the New Deal's labor statutes. The case that made Pitney labor's villain. Free online.
The opinion that complicates the caricature. On the same day in 1917, Pitney wrote for the Court upholding the constitutionality of state workers'-compensation laws against the claim that forcing employers to pay for workplace injuries without fault took their property without due process. Where Coppage read liberty of contract to shield employers, White let the states remake the law of industrial accident — a reminder that Pitney's conservatism was neither simple nor absolute. Read it against Coppage to see the whole justice. Free online.
The Holmes Devise volume for the White Court, where Pitney did all his work. Bickel and Schmidt set his labor and compensation opinions in the era's central struggle over how far the state could go in regulating the industrial economy — the argument that ran from Lochner through the New Deal. The best setting for a justice whose meaning lies entirely in that fight. Macmillan.
The leading modern study of Pitney — Belknap's case that the author of Coppage was no simple reactionary but a New Jersey progressive whose labor decisions were more mixed, and more principled, than the caricature.
The classic examination of the record Pitney is remembered for — the full run of his labor opinions, from Coppage to his quiet votes sustaining workmen's compensation. The evidence base for every later argument about him.

Where the Papers Are Kept
The Mahlon Pitney papers at the Library of Congress are modest; additional material survives in New Jersey repositories and in the records of his family, long prominent in the state's law and politics. A thin collection for a ten-year tenure. Visit →

Ideas for Further Research
- The divided conservative. Coppage v. Kansas and New York Central v. White sit awkwardly together: the same justice who used liberty of contract to strike an anti-yellow-dog law let the states impose no-fault liability on employers. Work out the principle, if there is one, that reconciles them — and ask whether 'Lochner-era conservatism' was ever as monolithic as the label suggests.
- The forgotten justice. Pitney is among the least-remembered men to serve a full decade on the Court, and he has no biography. Ask why some justices vanish from memory while contemporaries of similar weight endure, and what the absence of a Pitney biography tells us about how the Court's history gets written — around landmarks and personalities, not steady workhorses.
- The yellow-dog contract's long death. Coppage protected the yellow-dog contract in 1915; the Norris–LaGuardia Act (1932) and the Wagner Act (1935) finally killed it. Trace the twenty-year campaign, in Congress and the country, to overturn a single Supreme Court opinion — a case study in how the political branches answer the Court.
