Federal Rules of Criminal Procedure - Rule 26.2. Producing a Witness's Statement
(a) Motion to Produce.
After a witness other than the defendant has testified on direct examination, the court, on motion of a party who did not call the witness, must order an attorney for the government or the defendant and the defendant's attorney to produce, for the examination and use of the moving party, any statement of the witness that is in their possession and that relates to the subject matter of the witness's testimony.
(b) Producing the Entire Statement.
If the entire statement relates to the subject matter of the witness's testimony, the court must order that the statement be delivered to the moving party.
(c) Producing a Redacted Statement.
If the party who called the witness claims that the statement contains information that is privileged or does not relate to the subject matter of the witness's testimony, the court must inspect the statement in camera. After excising any privileged or unrelated portions, the court must order delivery of the redacted statement to the moving party. If the defendant objects to an excision, the court must preserve the entire statement with the excised portion indicated, under seal, as part of the record.
(d) Recess to Examine a Statement.
The court may recess the proceedings to allow time for a party to examine the statement and prepare for its use.
(e) Sanction for Failure to Produce or Deliver a Statement. If the party who called the witness disobeys an order to produce or deliver a statement, the court must strike the witness's testimony from the record. If an attorney for the government disobeys the order, the court must declare a mistrial if justice so requires.
