CASE ENTRY
Last Revised • July 4, 2026
Smith v. Cain reaffirmed and strengthened the constitutional principles established in Brady v. Maryland. The United States Supreme Court held that evidence affecting the credibility of a key prosecution witness must be disclosed when there is a reasonable probability that the outcome of the trial would have been different had the evidence been provided to the defense.

Cited to Support
Lyle C. May alleges that material impeachment and exculpatory evidence concerning key prosecution witnesses and the underlying investigation arising from the 1997 Asheville, North Carolina case was withheld from the defense. May cites Smith v. Cain to support the principle that undisclosed evidence affecting the credibility of a critical prosecution witness may be material under Brady when there is a reasonable probability that disclosure would have affected the outcome of the trial. May relies upon this authority to support his claim that suppressed evidence bearing upon witness credibility, reliability, and truthfulness undermines confidence in the verdict rendered against the Defendant.
