The D.C. Circuit today answered a question that it hadn’t addressed before — whether a grand jury witness has a right to read the transcript of his testimony in preparation for another appearance before the grand jury. The court held that the witness does indeed have that right. The court also mentioned that the district court may (or may not) allow the witness’s lawyer to accompany him to the transcript review. And it distinguished the situation in which a witness asks for a take-home copy of the transcript. In re Grand Jury, No. 06-3078 (D.C. Cir. June 22, 2007).
