Which statement about learned treatises use is true?

• A. They may be read to the jury but not admitted as evidence
• B. They must be admitted as evidence in all cases
• C. They cannot be used on cross-examination
• D. They can replace expert testimony

Answer: (A)

Learned treatises function as background authority that experts may rely on, not as independent proof. Courts permit a learned treatise to be read to the jury or cited on the stand to show the basis for an expert’s opinion, helping the jury understand why the expert believes what they do. But the treatise itself isn’t admitted into evidence as substantive proof; it doesn’t become independent evidence on its own. The key is that the expert’s testimony, grounded in the treatise (and the treatise’s authority), remains the evidentiary anchor. This material can also be used during cross-examination to challenge or limit the expert’s conclusions, but it cannot replace the need for expert testimony entirely. It’s not required in every case, and it’s not correct to say it can replace an expert’s testimony or that it must be admitted as evidence in all situations.
