Justice Benjamin Nathan Cardozo was an American jurist who served as Chief Judge of the New York Court of Appeals and then as an Associate Justice of the United States Supreme Court from 1932 until his death in 1938. He is widely regarded as one of the most influential judges in American history, and his opinions on product liability, negligence, fiduciary duty, and the reach of federal power are still read in nearly every American law school. His central idea was that legal rules have to evolve with the society they govern, and his career was a sustained demonstration of what that looks like in practice.
Early Life and Path to the Bench
Cardozo was born on May 24, 1870, into a prominent Sephardic Jewish family in New York City. His father, Albert Jacob Cardozo, sat on the New York Supreme Court but was forced to resign in 1872 under threat of impeachment because of ties to Boss Tweed’s Tammany Hall machine. The disgrace shadowed the family, and many who knew Benjamin believed it drove his lifelong attention to personal integrity and judicial ethics.
He entered Columbia University at fifteen and graduated in 1889, then studied at Columbia Law School for two years without completing a degree. He was admitted to the New York bar shortly after and spent roughly two decades in private practice, where he built a reputation for intellectual rigor and command of complex arguments.1Justia.

The New York Opinions That Still Define Private Law
Three of Cardozo’s opinions from his years on the Court of Appeals permanently reshaped American private law. They are the cases most lawyers associate with his name.
MacPherson v. Buick Motor Co. (1916)
MacPherson bought a Buick from a dealer. A defective wooden wheel collapsed while he was driving, and he was thrown from the car. Buick argued it owed him no duty because he had bought the car from a dealer rather than the manufacturer, which under the old rule cut off liability past the first buyer.3New York State Courts. MacPherson v Buick Motor Co
Cardozo swept that rule aside. If a product is reasonably certain to endanger life when negligently made, and the manufacturer knows it will be used by people beyond the original buyer, the manufacturer has a duty to build it carefully regardless of any contract. The decision effectively created modern product liability law and forced manufacturers across the country to take responsibility for the safety of goods reaching consumers.3New York State Courts. MacPherson v Buick Motor Co
Palsgraf v. Long Island Railroad Co. (1928)
Where MacPherson expanded liability, Palsgraf defined its outer boundary. Helen Palsgraf was standing on a railroad platform when guards helped a running passenger board a moving train. The passenger dropped a package that turned out to contain fireworks. The blast knocked over heavy scales at the far end of the platform and injured her.4New York State Unified Court System. Palsgraf v Long Is RR Co
Writing for a 4–3 majority, Cardozo held that the railroad owed Palsgraf no duty because her injury was not a foreseeable result of helping a man with an ordinary-looking package. “The risk reasonably to be perceived defines the duty to be obeyed,” he wrote. Negligence liability extends only to harms within a foreseeable zone of danger, not to every remote consequence of an act. Palsgraf remains the most taught case in American tort law.4New York State Unified Court System. Palsgraf v Long Is RR Co
Meinhard v. Salmon (1928)
Walter Salmon and Morton Meinhard had formed a joint venture to lease and operate the Hotel Bristol in New York. Salmon ran the property; Meinhard put up half the money. As the lease neared its end, Salmon quietly negotiated a lucrative new lease covering the Bristol site and several adjoining properties, keeping the opportunity entirely for himself and saying nothing to Meinhard.5New York State Unified Court System. Meinhard v Salmon
Cardozo held that joint venturers owe each other “the duty of the finest loyalty,” something far stricter than ordinary marketplace ethics. “Not honesty alone,” he wrote, “but the punctilio of an honor the most sensitive, is then the standard of behavior.” The opinion set what is still the governing standard for fiduciary duty in American business law.5New York State Unified Court System. Meinhard v Salmon
How He Thought About Judging
Cardozo believed that law is a living instrument that has to adapt as society changes. When existing rules fail to address a new situation, he argued, a judge must act as a cautious legislator, filling gaps with attention to both historical continuity and social welfare. Clinging to an old rule after it has stopped serving any useful purpose was, to him, itself a kind of injustice.
He set out this philosophy in The Nature of the Judicial Process, published in 1921 and drawn from his Storrs Lectures at Yale. The book is unusually candid about how judges actually decide cases. Cardozo identified four methods that compete for a judge’s attention: logic, which pushes toward consistency with existing principles; history, which traces where a rule came from; tradition, which draws on community custom and settled expectations; and sociology, which asks what outcome best serves justice and social welfare. Different cases call for different emphases, and the judge’s work is weighing them against each other. The book remains a staple of legal education because it refuses to pretend judging is mechanical while also refusing to surrender to the human element.
His courtroom opinions carried the same approach. In MacPherson he asked whether a rule designed for an era of simple goods still made sense in the age of automobiles. In Palsgraf he used careful reasoning to draw a workable boundary around negligence. His gift was making those adjustments feel principled rather than improvised.
Appointment to the United States Supreme Court
On February 15, 1932, President Herbert Hoover nominated Cardozo to the Supreme Court to replace the retiring Oliver Wendell Holmes Jr.6Supreme Court Historical Society. Benjamin Nathan Cardozo, 1932-1938 Hoover was a Republican nominating a Democrat, and the Court already had two New Yorkers and one Jewish justice. None of it slowed the confirmation. The Senate Judiciary Committee approved him unanimously, and the full Senate confirmed him by voice vote without debate or a roll call.
On the Court, Cardozo joined Justices Louis Brandeis and Harlan Fiske Stone to form the liberal bloc known as the “Three Musketeers.”7U.S. Capitol Visitor Center. US Supreme Court, Photograph, 1937 They often voted together to uphold federal and state economic regulations during the Great Depression, against a conservative bloc that fought to strike down New Deal legislation. The resulting 5–4 splits defined a generation of constitutional conflict over how much power the federal government could exercise over the economy.
The Supreme Court Opinions That Mattered Most
Upholding Social Security
Cardozo’s most consequential Supreme Court opinions involved the Social Security Act. In Steward Machine Co. v. Davis (1937), he wrote for a 5–4 majority upholding the federal unemployment tax, rejecting the argument that the tax coerced states into adopting federally approved unemployment programs in violation of the Tenth Amendment.8Legal Information Institute. Chas C Steward Mach Co v Davis In the companion case of Helvering v. Davis, decided the same day, he wrote the majority opinion upholding the Act’s old-age benefits. He read Congress’s power to tax and spend for the general welfare broadly, writing that the concept of general welfare “is not static” and that needs once local could become national as the country evolved. Whether Social Security was wise policy, he said, was a question for Congress; the judicial role was limited to whether Congress had the power to enact it.
Palko v. Connecticut and Ordered Liberty
In Palko v. Connecticut (1937), Cardozo addressed one of the structural questions at the heart of American constitutional law: which protections in the Bill of Rights apply to state governments through the Fourteenth Amendment? Frank Palko had been convicted of second-degree murder, the state appealed and won a new trial, and he was then convicted of first-degree murder. He argued this was double jeopardy.9Justia. Palko v Connecticut, 302 US 319 (1937)
Cardozo wrote that not every right in the Bill of Rights automatically limits the states. Only rights “implicit in the concept of ordered liberty,” those so fundamental that neither liberty nor justice could exist without them, are absorbed into the Fourteenth Amendment’s due process guarantee. He concluded that the ban on double jeopardy, while important, was not “of the very essence of a scheme of ordered liberty” and so did not restrict state prosecutions. The specific holding on double jeopardy was eventually overruled, but the “ordered liberty” framework shaped decades of incorporation doctrine and remains one of the most cited formulations in constitutional law.9Justia. Palko v Connecticut, 302 US 319 (1937)
Schechter Poultry and the Limits of Delegation
Cardozo was not an automatic vote for federal power. In A.L.A. Schechter Poultry Corp. v. United States (1935), the Court unanimously struck down the National Industrial Recovery Act, a centerpiece of the early New Deal. Cardozo agreed with the result and wrote a separate concurrence to sharpen the reasoning. He warned that the Act gave the President essentially unlimited authority to approve industry-written codes governing wages, hours, and trade practices, with no meaningful standards to guide or constrain that power. His phrase has become one of the most famous lines in administrative law: “This is delegation running riot.”10Justia. ALA Schechter Poultry Corp v United States, 295 US 495 (1935)
The concurrence shows the balance in his thinking. He was willing to uphold expansive federal programs when Congress set real standards, as in the Social Security cases. When the legislature tried to hand off its lawmaking power wholesale without meaningful guardrails, he drew the line. Power had to be, in his words, “canalized within banks that keep it from overflowing.”10Justia. ALA Schechter Poultry Corp v United States, 295 US 495 (1935)
Death and Legacy
Cardozo served on the Supreme Court for only six years. His health declined sharply at the end, and he died on July 9, 1938, at the age of sixty-eight.6Supreme Court Historical Society. Benjamin Nathan Cardozo, 1932-1938 His New York opinions in MacPherson, Palsgraf, and Meinhard are still taught as foundational cases in torts and business law. His Supreme Court opinions helped establish the constitutional footing for federal social welfare programs and the selective incorporation of the Bill of Rights. The Nature of the Judicial Process gave later generations of judges permission to acknowledge what had always been true: judging requires human judgment, not mechanical rule-following. His father left the bench in disgrace; Benjamin Cardozo left it as one of the most respected jurists in the country’s history.
