1. Photocopy of the advertisement
The advertisement is relevant to what Gallery represented, Pedro’s reliance, and the asserted contract terms. When offered to show that Gallery made the representation or its effect on Pedro, its assertion about the painting need not be true, so that use is not hearsay. If offered against Gallery for its truth and attributable to Gallery, it may also qualify as an opposing-party statement under Rule 801(d)(2).
Authentication requires evidence sufficient to support a finding that the item is what the proponent claims. Pedro’s recognition of the advertisement he saw, its logo, and its circumstances can provide that foundation. A trade inscription affixed in the course of business indicating origin can also be self-authenticating under Rule 902(7), depending on the foundation for this item. The logo does not independently prove every assertion printed beside it.
The best-evidence rule applies when proving the contents of a writing. Rule 1003 generally admits a duplicate to the same extent as an original unless there is a genuine question about the original’s authenticity or circumstances make using the duplicate unfair. No altered copy or genuine authenticity dispute is stated. The court properly could admit the photocopy, subject to the ordinary foundation and Rule 403 balance; damaging relevance is not unfair prejudice.
2. Pedro’s valuation testimony
A property owner often may give a lay opinion about value if grounded in personal knowledge and helpful under Rule 701. Ownership does not authorize a conduit for inadmissible expert conclusions. Pedro expressly derived his $10,000 figure by averaging three dealers’ appraisals rather than by an identified independent basis such as his own familiarity with comparable sales or the painting market.
The appraisals are out-of-court valuations offered to establish the painting’s value. No business-record or other exception is established. An average of three hearsay statements does not cure the hearsay, and Pedro has not been qualified as an expert entitled to rely under Rule 703 on otherwise inadmissible material. His $200,000 purchase price is within his personal knowledge; his separately stated appraisal-based valuation should be excluded or stricken absent a sufficient independent foundation.
3. Rex’s testimony
Under Rule 702 and the court’s gatekeeping function, expert testimony must come from a qualified witness, help the factfinder, rest on sufficient facts or data, and use reliable principles and methods reliably applied. A chemistry professor with experience retained by four galleries to date paintings has relevant scientific qualifications; he need not be an art dealer to analyze material age.
Rex tested the XYZ method against paintings of known age and obtained corresponding results. He also described its use by most experts. Testability and general acceptance support reliability, along with his application of the method to this painting. The record does not provide every possible Daubert consideration, such as error rate and peer review, but the factors are flexible rather than a mandatory checklist. The court should assess the actual foundation rather than assume either that a professor is automatically reliable or that a conflicting publication requires exclusion.
The age of the paint is relevant to whether a claimed seventeenth-century original is instead a modern reproduction. The testimony likely is admissible on this foundation, subject to the judge’s reliability determination. Whether Rex has a sufficient basis for an artistic-authorship conclusion beyond chemical age should be examined separately. Marie’s disagreement supplies contrary evidence rather than an automatic retrospective invalidation of the admission.
4. Learned-treatise excerpt
Rule 803(18) permits a statement in a reliable treatise, periodical, or pamphlet when relied on by an expert on direct examination or called to an expert’s attention on cross-examination, and the publication’s authority is established by expert admission or testimony, another expert, or judicial notice. Marie is stipulated to be an expert and identifies the publication as generally recognized reliable authority. Her discussion of its criticism of the method is relevant expert use, provided she relied on it in her direct testimony as the rule requires.
An admissible learned-treatise statement may be read into evidence but may not be received as an exhibit. The court could allow the properly founded quotation, but receiving the excerpt itself as an exhibit was error. This restriction prevents the jury from giving unsupervised written expert material disproportionate weight. Qualification of the publication does not remove the restriction.
5. Rex’s journal article
The article contradicts Rex’s testimony that XYZ is reliable and is relevant to impeach him on a central issue, not a collateral matter. It must first be authenticated as his work. He is a witness, not a party, so his authorship does not itself create an opposing-party admission against Pedro. The article also was not made under oath at a trial, hearing, deposition, or other qualifying proceeding and therefore does not become substantive evidence through Rule 801(d)(1)(A).
For this February 2023 exam, the then-existing Rule 613(b) required an opportunity for the witness to explain or deny the inconsistent statement and for the adverse party to examine him about it, unless justice otherwise required. It did not impose the later December 2024 rule’s usual sequencing requirement. Rex already was excused and left; the facts do not show the opportunity was supplied or that justice excuses it. The court ordinarily should withhold the extrinsic impeachment unless Rex can be recalled and the foundation completed. His departure is not proof that recall is impossible.
As substantive learned-treatise evidence, Rex’s article would require a separate Rule 803(18) foundation identifying it as reliable authority and proper expert use. His own experience and authorship do not establish that foundation automatically, and Marie qualified a different publication. Even if that foundation were later supplied, the admissible statement could be read, not admitted as a physical exhibit. Thus the article is not unconditionally admissible for its truth or as an exhibit on the stated facts.
