In what circumstances will a grand jury be bound by secrecy?

We are aware of these arguments, and recognize that an emphasis on secrecy may impair other values. For example, since grand jury proceedings are ex parte in nature, they lack the fundamental protections of due process and may generate misleading or ambiguous information that would likely be corrected in an adversary proceeding. See United States v. Scully, 225 F.2d 113, 116 (2d Cir.), cert. denied, 350 U.S. 897, 76 S.Ct. 156, 100 L.Ed. 788 (1955) (in grand jury proceedings "there is no right to counsel, no right of confrontation, no right to cross-examine or to introduce evidence in rebuttal and ordinarily no requirement that the evidence introduced be only such as would be admissible upon a trial" (citation omitted)).
