Learned Hand

Learned Hand (1872–1961) was an American federal judge whose opinions shaped free-speech law, statutory interpretation, and negligence doctrine.

United States v. Carroll Towing Co.: A 1947 negligence case in which Hand described a cost-benefit formula for determining whether precautions are required. Hand’s opinion supplied the negligence formula most closely associated with his name.
Hand formula: A negligence test comparing the burden of precautions with the probability and severity of harm. It formalizes the risk-balancing approach in Hand’s Carroll Towing opinion.
Oliver Wendell Holmes Jr.: An American jurist whose opinions and legal philosophy profoundly influenced twentieth-century law. Holmes’s free-speech opinions provided a major point of reference for Hand’s own thinking.
Negligence: A failure to exercise the care that a reasonably prudent person would use under the circumstances. Hand’s formula gave courts an influential economic account of when negligent conduct occurs.
Originalism: A method of constitutional interpretation that emphasizes the text’s original public meaning or understanding. Hand resisted treating abstract constitutional commitments as licenses for judges to impose personal convictions.
Masses Publishing Co. v. Patten: A 1917 case in which Hand distinguished advocacy of resistance from direct incitement under the Espionage Act. Hand’s narrow free-speech test later became a touchstone for debate over wartime censorship.
Statutory interpretation: The process of determining the meaning and legal effect of enacted legislation. Hand treated statutory language, purpose, and context as constraints on judicial interpretation.
Felix Frankfurter: An American legal scholar and Supreme Court justice known for judicial restraint and attention to institutional limits. Frankfurter promoted Hand’s judicial reputation and shared his concern about judicial overreach.
United States free speech law: The body of constitutional doctrine governing restrictions on expression under the First Amendment. Hand’s opinions and critiques helped shape debates over the proper limits of speech protection.
Textualism: A method of statutory interpretation that gives primary weight to the enacted text’s ordinary meaning. Hand’s contextual approach to statutes differs from modern textualism’s stronger emphasis on ordinary textual meaning.
