McDaniel v. Brown

¶1with whom Justice Scalia joins, concurring.

¶2I join the per curiam because it correctly holds that the Ninth Circuit erred in departing from Jackson’s mandate that a federal habeas court confine its sufficiency-of-the-evidence analysis to “the evidence adduced at trial” and, specifically, to “ ‘all of the evidence admitted by the trial court.’ ” Ante, at 130, 131 (quoting Lockhart v. Nelson, 488 U. S. 33, 41 (1988)); see Jackson v. Virginia, 443 U. S. 307 (1979). I write separately because I disagree with the Court’s decision to complicate its analysis with an extensive discussion of the Mueller Report. See ante, at 127-132. Defense counsel commissioned that report 11 years after respondent’s trial. See ante, at 121. Accordingly, the report’s attacks on the State’s DNA testimony were not part of the trial evidence and have no place in the Jacksoninquiry. See Jackson, supra, at 318; Lockhart, supra, at 40-42. That is all we need or should say about the report in deciding this case.

¶3The Court’s opinion demonstrates as much. The Court’s lengthy discussion of the Mueller Report, see ante, at 127-130, is merely a predicate to asserting that “even if” the Court of Appeals could have considered the report in its Jacksonanalysis, the report “provided no warrant for entirely excluding the DNA evidence or Romero’s testimony from that court’s consideration” because the report “did not contest that the DNA evidence matched Troy” or otherwise show that the State’s DNA estimates were “unreliable,” ante, at 132. Based on these observations, the Court concludes that the Mueller Report did not undermine the State’s DNA tests as “powerful inculpatory evidence.” Ibid.That is true, but even if the report had completely undermined the DNA evidence — which the Ninth Circuit may have mistakenly believed it did, see Brown v. Farwell, 525 F. 3d 787, 795-796 (2008) — the panel still would have erred in considering the report to resolve respondent’s Jacksonclaim. The reason, as the Court reaffirms, is that Jacksonclaims must *138be decided solely on the evidence adduced at trial. See ante, at 131. Accordingly, the Court need not correct any erroneous impressions the Ninth Circuit may have had concerning the report’s impact on the State’s DNA evidence to resolve respondent’s Jacksonclaim.* Because that is the only claim properly before us, I do not join the Court’s dicta about how the Mueller Report’s findings could affect a constitutional analysis to which we have long held such post-trial evidence does not apply. See Jackson, supra, at 318.
