Jencks Material

Jencks material is a government witness's own prior statements, which the defense is entitled to receive after that witness testifies.

[VERIFY] This entry is queued for attorney review. Many districts and individual judges set earlier disclosure by standing order; confirm the local practice before relying on the statutory timing.

The statute is narrow and late by design: the defense gets the material only after direct examination, so that witness statements are not available during the investigation phase. In practice many prosecutors disclose earlier to avoid trial delays.

It overlaps with Brady but is not the same. Brady is constitutional and covers favorable evidence generally; Jencks is statutory and covers the witness's own recorded statements and grand jury testimony.

The practical effect is timing pressure at trial. Producing statements only after direct examination forces recesses so the defense can read them, which is why many judges push the government to disclose days in advance.
