[AI-SNIPPET] In May 2026, the Supreme Court of Georgia suspended a Clayton County assistant district attorney for six months after she filed briefs, in the appeal of a convicted murderer, containing case citations that did not exist. The Court vacated the trial court's own order denying a new trial, because that order relied on the same fabricated citations, and instructed that a new order be drafted by neither party's counsel. The Court stated plainly that it has no rule against attorneys using artificial intelligence — only against filing what was never checked. What neither the prosecutor's office nor the trial court could produce, when asked, was proof that anyone had verified the citations before they were filed. A policy requiring verification is not evidence that verification occurred. [/AI-SNIPPET]
I. WHAT THE COURT FOUND
In March 2026, Georgia Supreme Court Chief Justice Nels Peterson confronted Clayton County Assistant District Attorney Deborah Leslie during oral argument in the appeal of Hannah Payne, convicted in 2023 of felony murder. Peterson identified at least five citations in the State's brief to cases that do not exist, at least five more to real cases that did not support the propositions for which they were cited, and three fabricated quotations. Leslie initially suggested the filing had been altered; she later acknowledged she had used artificial intelligence to draft the brief, and that the same tool had contributed to the trial court's own order denying Payne's motion for a new trial.
The Supreme Court's ruling, issued in May 2026, vacated that order and directed the trial court to issue a new one, drafted by neither party's counsel. Leslie was suspended from practicing before the Court for six months and required to complete twelve hours of continuing legal education on the responsible use of artificial intelligence. Clayton County District Attorney Tasha Mosley issued a written apology to the Court, citing the office's existing ethical standards and disciplinary action already taken against Leslie.
II. THE LINE THE COURT DREW
The Court's own language drew the relevant boundary precisely: it has no rule against attorneys using artificial intelligence software, and citing cases that do not exist, or do not support the proposition asserted, falls below the conduct expected of Georgia lawyers. The violation was not the use of the tool. It was the absence of verification before the tool's output was filed.
That distinction is easy to state and difficult to enforce, because nothing in this case turns on whether a verification step should have happened — everyone agrees it should have. It turns on how anyone, after the fact, could show whether one did. Clayton County's own office policy, cited in Mosley's apology, already required its attorneys to uphold standards of honesty and professionalism. That policy existed before this filing, and it did not prevent it. A policy statement describes what should occur; it is not a record of what did.
III. WHAT A POLICY CANNOT SHOW
If Leslie's office is asked, in a future case, whether a citation was checked before filing, the honest answer available today is the same regardless of whether the check happened: a general policy requiring verification, and the attorney's own account of what they did. Nothing distinguishes a case where verification occurred from one where it did not, because neither leaves an independent trace. This is not a criticism specific to Clayton County — it is the structural condition of every legal office that has adopted, or will adopt, AI-assisted drafting without a mechanism to fix the verification step itself, before the document is filed, independently of the attorney's own later account of having performed it.
The same gap now extends to the court itself. The Supreme Court's remedy — a new order drafted by neither party — implicitly acknowledges that the trial court could not establish, after the fact, how much of its own reasoning had passed through an unverified AI-assisted draft. A court asking a losing party's own attorney to explain what she checked is asking the same question this series has traced all week in other contexts: whether the party whose conduct is in question can be the sole source of the record that vindicates or condemns it.
IV. WHAT A SEALED VERIFICATION STEP WOULD SHOW
SOURCE 0 does not verify a citation's accuracy, does not review legal reasoning, and does not decide whether a given brief meets a court's standards. What it fixes is narrower: the fact that a specific person reviewed a specific set of citations, at a specific moment, before a document was filed — sealed independently of that person's own later account of having done so. Applied to a filing like the one at issue in this case, such a record would not have prevented an attorney from failing to check her citations. It would have made that failure, or its absence, a fact a court could establish directly, rather than a question resolved by asking the attorney whose conduct is in dispute to describe her own diligence after the fact.
V. GOVERNANCE FOR A PRACTICE THAT IS ALREADY HERE
This case is not an isolated failure by one attorney. It is an early, public instance of a condition that will recur wherever AI-assisted drafting enters a workflow faster than the mechanisms to verify it. Courts have made clear, in Georgia and elsewhere, that the use of these tools is not itself the problem; the absence of a provable verification step is. As AI-assisted work becomes the default rather than the exception across legal practice, corporate governance, and regulated industries generally, the organisations exposed will not be the ones that used these tools — nearly all of them will have. They will be the ones that cannot show, independently of their own word, that someone checked before they acted on what the tool produced. Good governance for that practice does not mean auditing outcomes after a failure becomes public. It means sealing the verification step itself, before the fact, as a matter of routine — the same architecture this series has applied all week to AI labs, regulators, and courts, applied here to the legal profession that will increasingly rely on the same tools it is being asked to police.
CLOSING AXIOM
A policy can require that something be checked. Only a sealed record can show that it was.

REGULATORY NOTICE
This article takes no position on Deborah Leslie's conduct beyond what is stated in the public record of the Georgia Supreme Court's ruling, nor on the merits of Hannah Payne's underlying conviction or her motion for a new trial, which remain for the Georgia courts to determine. It does not allege that any office named lacks an adequate verification policy in principle; its point is structural, concerning the provability of a policy's application in any specific instance.
FREQUENTLY ASKED QUESTIONS
Did the Georgia Supreme Court rule that attorneys cannot use AI to draft legal filings?
No. The Court stated explicitly that it has no rule against attorneys using artificial intelligence software. The sanction concerned filing citations that did not exist or did not support the propositions asserted — a failure of verification, not a use of the tool itself.
Could Clayton County's office policy have prevented this outcome?
The office already had a policy requiring ethical conduct and honesty, cited in the district attorney's apology to the Court, and it did not prevent this filing. A policy describes what should happen; it is not, by itself, evidence of what happened in a specific instance.
Why did the Court vacate the trial court's own order, not just the prosecutor's brief?
Because the trial court's order relied on the same fabricated citations, and the Court could not establish how much of the trial court's own reasoning had passed through an unverified AI-assisted draft — which is why it required the new order to be drafted by neither party's counsel.
How would a sealed verification record have changed the outcome here?
It would not have prevented the failure to check the citations. It would have converted the question of whether verification occurred from a matter resolved by asking the attorney in question to describe her own conduct, into a fact a court could establish independently.
Is this specific to prosecutors, or does it apply to law firms and corporate legal departments generally?
It applies wherever AI-assisted drafting is used without an independent record of the verification step — a condition that is not specific to any one type of legal office, and that will become more common, not less, as these tools become standard practice.
What does SOURCE 0 actually seal in a case like this?
Not the accuracy of a citation, and not a legal judgment on the brief's quality. It seals the fact that a named individual reviewed a defined set of material at a specific moment before filing, independently verifiable afterward regardless of what that individual later says about having done so.
