Whitton v. Dixon: Improper Use of Post-Trial DNA Evidence

This episode details a Supreme Court of the United States decision to vacate a lower court's ruling in the capital case of Gary Richard Whitton. The central dispute involves a Giglio violation concerning a jailhouse informant who provided false testimony about his criminal history during Whitton’s murder trial. While the Eleventh Circuit acknowledged the testimony was false, it denied relief by citing post-trial DNA evidence to prove that any error was harmless. The Supreme Court ruled this analysis improper, asserting that evidence never seen by the jury cannot be used to determine if a constitutional error influenced the original verdict. In a sharp dissent, Justice Thomas argued that the error was inconsequential given the other evidence and criticized the Court for prioritizing a "technicality" over more significant cases.
