Which provision governs the disclosure of witness statements for use in trial and appellate proceedings?

• A. Giglio
• B. Rule 16
• C. Brady v. Maryland
• D. Jencks Act

Answer: (D)

The Jencks Act governs the disclosure of witness statements after that witness has testified, to enable cross-examination and potential appellate review of trial conduct. In federal prosecutions, once a government witness has testified on direct examination, the government must produce the witness’s prior statements that relate to the subject matter of the testimony for the defense to review and use during cross-examination. This mechanism ensures the defense can challenge credibility and accuracy by accessing statements the witness previously made. Brady v. Maryland is about disclosure of exculpatory evidence favorable to the defense, which can include but is not limited to witness statements. Giglio v. United States extends Brady to impeaching information about a witness’s credibility, including some statements, but neither framework provides the specific post-testimony production requirement that the Jencks Act establishes. Rule 16 covers broader pretrial discovery, not the focused production of a witness’s prior statements after testimony for use at trial.
