What is the learned hand rule?
Asked by: Carson West | Last update: April 25, 2026Score: 4.7/5 (24 votes)
The Learned Hand Rule is a legal test for negligence, formulated as B < P x L, where liability for failing to prevent harm exists if the Burden (B) of taking precautions is less than the expected cost of the harm (the Probability (P) of injury multiplied by the Loss (L) if it occurs). Developed by Judge Learned Hand in the case U.S. v. Carroll Towing Co., it's a cost-benefit analysis to determine if a duty of care was breached, suggesting precautions should be taken if they're cheaper than the probable accident cost.

Presidents Taft, Coolidge, Hoover, and Roosevelt all passed him over for various reasons, often political or related to other candidates.
