| Holding | |
| The Court of Appeals erred in holding that the prosecutor's failure to disclose evidence that could have been used effectively to impeach important Government witnesses requires automatic reversal. Such nondisclosure constitutes constitutional error and requires reversal of the conviction only if the evidence is material in the sense that its suppression might have affected the outcome of the trial. | |
