A Clayton County prosecutor has formally apologized to the Georgia Supreme Court after acknowledging that artificial‑intelligence tools were used to generate legal citations that do not exist, a rare and highly public misstep that has put Atlanta’s legal community at the center of a growing national debate over AI’s role in the courtroom.
The revelation, first reported by WSB‑TV, came during a high‑profile murder appeal and prompted an internal investigation, a corrective filing, and renewed scrutiny over how attorneys verify AI‑assisted work before submitting it to the courts. [wsbtv.com]
What Happened
According to WSB‑TV and court records, Clayton County Assistant District Attorney Deborah Leslie prepared and filed a proposed legal order for the Georgia Supreme Court in the murder appeal of Hannah Payne, who was convicted in the 2019 killing of motorist Kenneth Herring.
During oral arguments, Georgia Supreme Court Chief Justice Nels S. D. Peterson flagged multiple citations in the prosecution’s filing that could not be found in any legal database. He identified:
- At least five case citations that do not exist
- Five additional citations that did not support the propositions for which they were cited
- Three quotations attributed to cases that could not be verified
After questions from the bench, the Clayton County District Attorney’s Office launched an internal review. Leslie later acknowledged that she used artificial‑intelligence tools as part of her legal research and failed to independently verify the AI‑generated citations before including them in the filing. She submitted a written apology to the court, and nine citations were formally withdrawn. [wsbtv.com], [ajc.com]

Official Response from the DA’s Office
Clayton County District Attorney Tasha Mosley confirmed that the use of AI violated office policy and emphasized that AI‑generated work is not a substitute for professional verification. In statements obtained by WSB‑TV and FOX 5 Atlanta, Mosley said bluntly that misleading the court—intentionally or not—is unacceptable and that disciplinary action is being taken.
Mosley also told reporters the office is expanding its internal policies on technology use, including artificial intelligence, to prevent similar incidents in the future. [wsbtv.com], [fox5atlanta.com]

Why This Matters in Atlanta
Atlanta is one of the Southeast’s largest legal and technology hubs, home to major law firms, law schools, startups, and a high‑volume court system. The integration of AI tools into legal drafting and research is already common across metro Atlanta—from public defender offices to corporate firms downtown and in Midtown.
This incident highlights a central tension: while AI can speed up research and drafting, it is also known to produce “hallucinations”—confident‑sounding but false information—including fabricated case law. In legal contexts, those errors can undermine judicial trust, slow proceedings, and carry serious ethical consequences.
The Georgia Supreme Court episode underscores that human review remains an ethical obligation, not an optional step, even when technology accelerates the process.
A Broader Legal Reckoning with AI
Atlanta’s case is not isolated. Courts across the country have disciplined attorneys for submitting AI‑generated legal citations without verification. Legal scholars and judges increasingly warn that AI is a drafting tool, not an authority.
For readers looking to understand why AI systems fabricate plausible‑sounding citations, policy groups like Brookings provide accessible explanations of AI hallucinations and their limits:

In Georgia, guidance is likely to come from the State Bar of Georgia, which oversees attorney ethics and continuing legal education requirements. While no new rule has yet been formally announced, bar officials and legal educators are closely watching the case.

What Comes Next
At this stage:
- The Georgia Supreme Court has not imposed sanctions, but it has ordered explanations and corrections.
- The contested citations have been withdrawn.
- The underlying murder appeal has not yet been ruled on, and officials say the erroneous citations did not alter the court’s understanding of the substantive record.
The Larger Takeaway
Seen one way, the episode is a cautionary tale about moving too quickly with new technology. Seen another, it’s a stress test—one that Atlanta’s legal system can use to develop stronger safeguards, training, and transparency around AI use.
Atlanta has the capacity to lead on this issue. With its mix of technical talent, legal expertise, and civic institutions, the city is well‑positioned to define responsible AI adoption in law—one that improves efficiency without eroding accuracy or trust.
For now, the message from the bench is unmistakable: AI may assist lawyers, but it cannot replace their duty to verify every word placed before a judge.
We’ll continue to track updates as court orders, bar responses, or policy changes emerge.
