Under New York rules, cross-examination credibility may be addressed if the opposing expert

• A. They may only be cross-examined about their name
• B. Their credibility is never a topic on cross
• C. Cross-examination can address credibility if relied on by opposing expert
• D. Only direct testimony can discuss credibility

Answer: (C)

The main idea is that in New York, you can challenge an opposing expert’s credibility on cross-examination, but only to the extent that the opposing expert’s opinion relies on the credibility of the witness you’re cross-examining. If the other side’s expert has based their conclusions on that witness’s testimony or findings, you may question the witness’s reliability, bias, or basis to test how much weight the opposing expert’s opinion should carry. If the opposing expert hasn’t relied on that witness, then cross-examining for credibility isn’t the right vehicle. This keeps credibility challenges tethered to the actual foundations of the opposing party’s expert opinion. So the correct approach is that cross-examination can address credibility if relied on by the opposing expert. The other options are flawed: cross-examining a witness solely about their name is not the issue; credibility can be a topic on cross under the right circumstances; and credibility is not confined to direct testimony—cross-examination is a primary way to probe credibility.
