Understanding the Learned-Treatise Rule: A Key Legal Doctrine
Definition & Meaning
The learned-treatise rule is a legal principle that allows certain published texts to be considered authoritative sources of information in court. This rule is an exception to the hearsay rule, meaning that statements from recognized treatises, periodicals, or pamphlets can be admitted as evidence. These statements are primarily used to support the examination or cross-examination of expert witnesses. However, while the statements can be read in court, they cannot be submitted as physical exhibits. To qualify as a reliable authority under this rule, the text must be the type of material that experts in the relevant field typically rely on.
