Justice Manual § 9-27.750

The attorney for the government should disclose to defense counsel, reasonably in advance of the sentencing hearing, any factual material not reflected in the presentence investigation report that he/she intends to bring to the attention of the court.

Comment. Due process requires that the sentence in a criminal case be based on accurate information. See, e.g., Moore v. United States, 571 F.2d 179, 182-84 (3d Cir. 1978). Accordingly, the defense should have access to all material relied upon by the sentencing judge, including memoranda from the prosecution (to the extent that considerations of informant safety permit), as well as sufficient time to review such material and an opportunity to present any refutation that can be mustered. See, e.g., United States v. Perri, 513 F.2d 572, 575 (9th Cir. 1975); United States v. Rosner, 485 F.2d 1213, 1229-30 (2d Cir. 1973), cert. denied, 417 U.S. 950 (1974); United States v. Robin, 545 F.2d 775 (2d Cir. 1976). JM 9-27.750 is intended to facilitate satisfaction of these requirements by providing the defendant with notice of information not contained in the presentence report that the government plans to bring to the attention of the sentencing court.
