D.N.M.: Does Brady apply to suppression hearings?

If Brady likely applies to suppression motions, there was no showing that the evidence was sufficiently impeaching to change the outcome. United States v. Harmon, 871 F. Supp. 2d 1125 (D. N.M. 2012).*

Circuit courts have split on the issue whether Brady v. Maryland’s restrictions apply to suppression hearings, although it is not likely that a prosecutor must disclose impeachment evidence before a suppression hearing in light of the Supreme Court’s conclusion in United States v. Ruiz that a prosecutor does not have to disclose impeachment evidence before the entry of a guilty plea. In an unpublished opinion, the Tenth Circuit, without discussing whether Brady v. Maryland applies to a suppression hearing, rejected a defendant’s argument that the prosecution violated Brady v. Maryland by failing to disclose impeachment evidence before a suppression hearing on the basis that the evidence was not impeachment evidence and not material. See United States v. Johnson, 117 F.3d 1429, 1997 WL 381926 at *3 (10th Cir. 1997) (unpublished table decision). …

The United States Court of Appeals for the District of Columbia has recognized that “it is hardly clear that the Brady line of Supreme Court cases applies to suppression hearings,” because “[s]uppression hearings do not determine a defendant’s guilt or punishment, yet Brady rests on the idea that due process is violated when the withheld evidence is ‘material either to guilt or to punishment.'” United States v. Bowie, 198 F.3d 905, 912 (D.C. Cir. 1999). Without deciding the issue and in an unpublished opinion, the United States Court of Appeals for the Sixth Circuit quoted with approval this language from United States v. Bowie. See United States v. Bullock, 130 F.App’x 706, 723 (6th Cir. 2005) (unpublished) (“Whether the suppression hearing might have come out the other way, however, is of questionable relevance to the Brady issues at stake here.”). The Fifth Circuit and the United States Court of Appeals for the Ninth Circuit held, before the Supreme Court issued its United States v. Ruiz decision, that Brady v. Maryland restrictions apply to suppression hearings. See United States v. Barton, 995 F.2d 931, 935 (9th Cir. 1993) (“[W]e hold that the due process principles announced in Brady and its progeny must be applied to a suppression hearing involving a challenge to the truthfulness of allegations in an affidavit for a search warrant.”); Smith v. Black, 904 F.2d 950, 965-66 (5th Cir. 1990) (“Timing is critical to proper Brady disclosure, and objections may be made under Brady to the state’s failure to disclose material evidence prior to a suppression hearing.”), vacated on other grounds, 503 U.S. 930 (1992)). The United States Court of Appeals for the Seventh Circuit held that, under its precedent and the law from other circuits, it was not “obvious” for clear-error purposes that “Brady disclosures are required prior to suppression hearings.” United States v. Scott, 245 F.3d 890, 902 (7th Cir. 2001).
