Supreme Court Justice Clarence Thomas said Monday that the High Court had intervened in a death row case unnecessarily, as the bench weighed arguments over an allegedly false statement used to convict a man of murder and DNA evidence presented years later.
The case, Whitton v. Dixon, centers on Gary Whitton, who was convicted of murder and sentenced to death. At trial, prosecutors relied in part on testimony from a jailhouse informant who claimed Whitton had confessed and asserted that he had no prior criminal history. That statement was later shown to be false based on records already in the prosecution’s possession.
Whitton argued that the reliance on this testimony violated his constitutional rights under Giglio v. United States, a landmark precedent that bars prosecutors from knowingly presenting false testimony. The central legal question before the courts was whether that false testimony could have influenced the jury’s verdict.
Thomas, however, disagreed with the Supreme Court’s involvement in the matter entirely.
“It is unfortunate that the Court chose to intervene at the request of a convicted murderer to correct the Eleventh Circuit’s inconsequential foot fault,” he wrote in his dissent, joined by fellow conservative Samuel Alito.
“What makes it even worse is that the Court does so even while it refuses to correct far more consequential errors for law-abiding citizens, such as the discriminated-against families in Boston, Staff Sergeant Beck’s widow, and the students seeking to challenge university censorship,” Thomas concluded, pointing to other cases the court has decided not to hear.
Who Is Gary Whitton?
Whitton is a Florida man who was convicted and sentenced to death for the 1990 murder of his friend, James Maulden, in a case that has been litigated for decades in state and federal courts.
According to court records, Whitton was with Maulden on the night of the killing, helping him withdraw more than $1,100 from his bank account before taking him to a motel, where Maulden was later found dead.
Prosecutors argued that Whitton killed Maulden inside the motel room after gaining access to his money, pointing to a combination of physical evidence, witness testimony, and inconsistencies in Whitton’s own account of events.
Whitton testified in his own defense, claiming he returned to the motel later and found Maulden already dead, and that any blood on his clothing came from encountering the scene after the fact.
A jury rejected that explanation, convicting Whitton of murder and recommending a death sentence.
While the Supreme Court case now before the justices focuses on whether false testimony from a jailhouse informant violated Whitton’s rights, the underlying conviction rests on what lower courts have repeatedly described as extensive evidence tying him to the killing.
What the Court Decided
In a brief, unsigned opinion, the Supreme Court ruled that a federal appeals court made a critical error by considering new DNA evidence—discovered years after Whitton’s trial—when determining whether the false testimony materialized into a prejudicial impact.
The U.S. Court of Appeals for the Eleventh Circuit had previously acknowledged that the informant’s testimony was false and that prosecutors were aware of its inaccuracy. Still, the appellate court upheld Whitton’s conviction, citing “overwhelming evidence” of guilt, which included DNA test results obtained long after the original trial concluded.
The Supreme Court rejected that approach, emphasizing that the governing legal standard strictly focuses on the impact of the error on the specific jury that heard the case. Because the new DNA evidence “was not presented to the jury,” the court noted, it “could not have influenced the jury’s verdict” and should not have factored into the appellate court’s decision.

What Clarence Thomas Said
Thomas dissented from the majority, arguing the court stepped in unnecessarily over what he described as a minor issue that did not affect the ultimate outcome of the case.
The justice contended the appellate court’s reference to the subsequent DNA evidence amounted to nothing more than a passing mention and was not central to its core reasoning. He maintained that the conviction was robustly supported by “overwhelming evidence,” including physical evidence and witness testimony, independent of the disputed informant’s statements.
Thomas also argued Whitton was procedurally barred from relief because he failed to properly raise this specific claim in state court—a strict statutory requirement for securing federal habeas corpus relief.
More broadly, he criticized the court for intervening to correct what he framed as a technical error while simultaneously declining to review other cases he views as far more consequential. He suggested the ruling would likely have little practical effect on the litigation, noting that the lower courts could easily reach the same conclusion on remand.
What Happens Next
The case now returns to the Eleventh Circuit, which must decide whether the false testimony could have affected the jury’s verdict based solely on the evidence presented at trial.
That determination could shape whether Whitton ultimately gets a new trial, though the Supreme Court left that question entirely open.
