In Turner v. United States, No. 15-1503, and Overton v. United States, No. 15-1504 -- post-conviction cases arising from the District of Columbia and involving a murder conviction and seven petitioners -- the Supreme Court held that certain evidence possessed by the government but not disclosed to the defense was not "material" for purposes of Brady v. Maryland. In an opinion by Justice Breyer, the Court "examine[d] the trial record, evaluat[ed] the withheld evidence in the context of the entire record, and determine[d] in light of that examination" that there was no "reasonable probability that, had the evidence been disclosed, the result of the proceeding would have been different."
Justice Gorsuch did not participate. Justices Kagan and Ginsburg dissented.
