Bases of opinion testimony by experts

activein force · 2026-09-24 – presentact-effective-date

An expert may base an opinion on facts or data in the case that the expert has been

made aware of or personally observed. If experts in the particular field would

reasonably rely on those kinds of facts or data in forming an opinion on the subject, they

need not be admissible for the opinion to be admitted. But if the facts or data would

otherwise be inadmissible, the proponent of the opinion may disclose them to the jury

only if their probative value in helping the jury evaluate the opinion substantially

outweighs their prejudicial effect.
