My original reaction to the proposal to vacate and remand in the light of United States v. Mandujano, 425 U.S. 564d 212 (1976), was exactly that expressed by Mr. Justice MARSHALL in dissent. For as a Circuit Judge I had the experience of trying to decipher similar delphic orders, and I agree completely that a constitutional holding is not controlling on a question involving nothing more than an exercise of an appellate court's supervisory power. Nevertheless, there is an omission in the Court of Appeals opinion which makes it appropriate for that court to re-examine its holding.
grand jury witness adequate warnings does not lead inexorably to the conclusion that the witness cannot be prosecuted for perjury. Cf. United States v. Knox, 396 U.S. 77, 82. The Court of Appeals opinion seems to assume that the conclusion necessarily follows from the premise. Since I think it would be appropriate for that court to address that precise point in the first instance, I acquiesce in the remand.
decision which did not assume the existence of such a constitutional right. And it is clear that the well-established supervisory power of the courts of appeals over the district courts in their respective jurisdictions is not limited to enforcing constitutional rights. See, e. g., Cupp v. Naughten, 414 U.S. 141, 146 (1973); Barker v. Wingo, 407 U.S. 514, 530 n. 29 (1972); United States v. Thomas, 146 U.S.App.D.C. 101, 449 F.2d 1177, 1185-1187 ( 1971) (en banc); cf. e. g., Ristaino v. Ross, 424 U.S. 589, 597 n. 9, 96 S. Ct. 1017 (1976); Murphy v. Florida, 421 U.S. 794, 797-798 (1975); id., at 804 (Burger, C. J., concurring).
[Footnote *] The Court of Appeals determined that it is the universal practice of United States Attorneys in the Second Circuit to warn a grand jury witness who is the target of an investigation. Respondent was called before the grand jury by a Strike Force attorney operating in the Eastern District of New York but based in Washington. She received no warning.
