Used for these tasks
Each task page says how far AI may help with the task and what the lawyer must review.
How AI may be used
A tool may insert the case caption, the charge as the charging document prints it, and the prosecutor's name from the appearance.
AI may
- Fill the caption from the charging document
- Leave the federal or state block the lawyer did not select out of the draft the lawyer is editing
- List Rule 16 categories only in a federal draft
AI must not
- Must not recite a factual account of the offense
- Must not tell a state prosecutor that Justice Manual 9-5.001 binds that office
- Must not demand witness statements that Rule 16(a)(2) excludes, beyond 18 U.S.C. 3500
- Must not send the letter
The lawyer checks
- The forum block matches the court
- The Brady paragraph quotes the holding that was opened, including materiality to guilt or punishment
- The Giglio paragraph is about information that bears on a witness's credibility, of the kind in that case
- The lawyer has read the reciprocal-discovery warning before a federal Rule 16 request goes out
Method: how the Green, Yellow and Red levels are decided. This is guidance for planning, not legal advice.
