Expert Opinion Without Underlying Facts
Oakley Osei, a forensic accountant retained by Orion Technologies, took the stand in a contract dispute. He stated his conclusion that the defendant had overstated revenues without first describing the specific ledgers or calculations supporting that view. Defense counsel then cross-examined him about those underlying materials.
Improper Allusion During Examination
Orla O'Malley represented Otis Olsen at trial. While questioning a witness on the stand, she alluded to an alleged prior settlement offer that she could not reasonably expect to prove with admissible evidence. The court sustained the objection and instructed the jury to disregard the reference.
No Adverse Inference Instruction
Odin Obeng chose not to testify in his criminal trial. Upon timely request, the court instructed the jury that it must draw no adverse inference from his decision to remain off the stand. The instruction prevented the prosecutor from commenting on his silence.
Deposition Used as Live Testimony
Orion Orlov's deposition was read at trial after he became unavailable. The court treated the transcript as if Orlov were present and testifying on the stand, provided the testimony satisfied the Federal Rules of Evidence.
Spousal Privilege Invocation
Orlando Okafor's spouse was called to testify against him in a criminal proceeding. She invoked the privilege and refused to take the stand, preventing any compelled testimony about confidential marital communications.
Out-of-Court Statement as Hearsay
Oakridge Manufacturing sought to introduce a supplier's earlier statement through a third-party witness. Because the supplier had not made the statement while testifying on the stand at the current trial, the court analyzed it under the hearsay definition.
Common questions
Frequently Asked
6
May an expert witness state an opinion on the stand without first disclosing the underlying facts or data?+
Yes. Under the governing rule an expert may state an opinion and give the reasons for it without first testifying to the underlying facts or data unless the court orders otherwise. The expert may still be required to disclose those facts or data on cross-examination.

What ethical limits apply to a lawyer's statements while a witness is on the stand?+
A lawyer must not allude to any matter the lawyer does not reasonably believe is relevant or that will not be supported by admissible evidence. The lawyer also may not assert personal knowledge of facts in issue except when testifying as a witness or state a personal opinion about the credibility of a witness.
Is a criminal defendant entitled to an instruction when choosing not to take the stand?+
Yes. Upon timely request a non-testifying defendant is constitutionally entitled to an instruction that the jury must not draw any adverse inference from the failure to testify.
Supporting sources
When may a deposition be used in place of live testimony from the stand?+
A deposition may be used at a hearing or trial to the extent it would be admissible under the Federal Rules of Evidence if the deponent were present and testifying on the stand, provided the party against whom it is offered was present or had reasonable notice of the deposition.
Supporting sources
May one spouse be compelled to testify against the other while the witness spouse is on the stand?+
No. A married person may not be compelled to testify against her spouse in any criminal proceeding. In federal court the privilege belongs to the witness spouse, who may choose to testify, while in most state courts the party spouse may prevent the testimony.
Supporting sources
When is an out-of-court statement considered hearsay because the declarant is not on the stand?+
A statement is hearsay if the declarant does not make it while testifying at the current trial or hearing and a party offers it to prove the truth of the matter asserted.
