With a December 3, 2026 execution date on the books, Blount County Circuit Court Judge David R. Duggan has ordered state-appointed experts to evaluate death-row inmate Gary Wayne Sutton, setting up a high-stakes fight over whether Tennessee can legally put him to death.
The order, issued after a hearing this week, directs that any interviews or psychological testing be recorded and that Sutton’s defense team get advance notice before the state’s experts sit down with their client. His lawyers argue those evaluations are central to their claim that Sutton is intellectually disabled and therefore constitutionally ineligible for execution. For now, the court is keeping an existing schedule in place as both sides gear up for the exams.
What The Judge Ordered
In court, Duggan emphasized that the only question on the table is whether Sutton meets the legal standard for intellectual disability and declined to widen the inquiry beyond that issue. He ordered that all evaluations be recorded and that prosecutors give at least 48 hours’ notice before any testing, so the defense can prepare, observe and lodge objections in real time.
Defense attorneys told the court those safeguards are needed to head off what they called “irrelevant tests” and to protect Sutton’s ability to challenge the process later. The ground rules for the exams, including the recording requirement and notice window, were detailed at the hearing, according to Death Penalty News and Updates.
Prosecutors' Evaluation And Contested Motions
Duggan denied a defense request to force the state to reveal, ahead of a previously agreed deadline, the names of its experts and the exact battery of tests they plan to use. Prosecutors will be able to hold that information until the scheduled disclosure date.
At the same time, the judge sided with Sutton’s lawyers on another front, granting a motion to quash the state’s effort to obtain Department of Children’s Services records tied to Sutton’s background. Duggan narrowed the scope of the state’s evaluations to the single issue of intellectual disability and ordered that all results be preserved on the record for potential use in later hearings or appeals, according to WATE 6 On Your Side.
Case Background And The Court Calendar
Sutton was convicted in the early 1990s in the killings of Tommy Griffin and Griffin’s sister, Connie Branan, and has been on Tennessee’s death row since the mid-1990s. The Tennessee Supreme Court reset his execution date to December 3, 2026 in a written order that also spells out how the Department of Correction must notify Sutton of his chosen method of execution.
His co-defendant, James Henderson Dellinger, was also sentenced to death and died in 2023 while awaiting execution. The reset order and related filings in Sutton’s case are publicly available through the Tennessee Supreme Court.
Why The Intellectual-Disability Claim Matters
Sutton’s lawyers point to long-standing IQ scores clustered around the 70-point mark, along with expert testimony about his adaptive functioning, as proof that he cannot legally be executed under the Eighth Amendment. A forensic neuropsychologist who previously evaluated Sutton described him as having “essentially no more than a 6th-grade education,” evidence the defense says reflects significantly impaired adaptive skills.
The U.S. Supreme Court has ruled that executing people with intellectual disability violates the Constitution, a precedent that looms over Sutton’s case and will guide Duggan’s review. That rule traces back to Atkins v. Virginia, and the current legal posture of Sutton’s claim has been detailed in coverage by Death Penalty News and Updates.
Where This Fits In Tennessee’s Death-Penalty Fight
The Sutton hearing is unfolding as Tennessee tries to restart executions after a statewide pause in 2022 and a subsequent overhaul of its lethal-injection protocol. That halt, along with a later switch to a single-drug pentobarbital protocol, has triggered fresh litigation and louder demands for transparency around how the state prepares for executions.
Advocacy groups and defense teams have urged courts and elected officials to scrutinize both the new procedures and the individual cases now moving back onto the calendar. The broader statewide backdrop, including the protocol changes and renewed legal challenges, has been chronicled by the Associated Press and analyzed by the Death Penalty Information Center.
Next Steps And What To Watch
Under Duggan’s order, state-appointed experts will conduct recorded evaluations of Sutton, with short advance notice to the defense. Those exam results could surface in future hearings or appeals, especially if the two sides clash over testing methods or how to interpret the findings.
If the court ultimately rules that Sutton is intellectually disabled, that finding would legally bar Tennessee from executing him. In the meantime, family members and supporters have been pressing elected officials to step in, organizing rallies at the State Capitol and urging the governor to review the case.
