Here are the materials in United States v. Henderson (D. Mont.):
The Court agrees with Henderson that if the jury would have heard the undisclosed impeaching evidence relating to Cabanas, they may have changed the way they viewed Cabanas’s testimony. The Court finds, however, that the absence of such evidence had no impact on the jury’s verdict given the relative insignificance of Cabanas’s testimony compared to the other witnesses, and the overwhelming weight of evidence against Henderson provided by other witnesses.
