Under New York rules, direct examination may show the basis for an expert's opinion.

• A. Not allowed on direct
• B. Allowed on direct
• C. Only after cross-examination
• D. Only with judicial notice

Answer: (B)

In New York, the basis for an expert’s opinion may be shown on direct examination. This allows you to ask the expert to explain the data, facts, or methods he relied on to form the opinion—such as lab results, measurements, or established standards. Revealing the basis on direct helps the jury understand why the expert believes the conclusion is valid and how to evaluate its reliability. It isn’t restricted to cross-examination, nor is it contingent on judicial notice.
