Ex parte Allen Michael Lee, No. 10-22-00281-CR (Tex. App.—Waco July 19, 2023) (published)
In the Tenth Court of Appeals of Texas, Chief Justice Tom Gray held that appellant Lee's brief cited three published cases that do not exist, noted the Argument section may have been AI-prepared, and overruled the issue as inadequately briefed. The court imposed no penalty and expressly declined a show-cause order or State Bar referral.

- Conduct
- Appellant's counsel filed a habeas/bail-reduction appeal brief whose Argument section cited three published Texas Court of Criminal Appeals cases that do not exist; each citation was a jump-cite into an unrelated case, two of them from Missouri. The State flagged the citations and counsel never corrected them. The court observed the Argument section may have been prepared by AI.

What was fabricated or misused
- Ex parte Vasquez, 248 S.W.3d 454 (Tex. Crim. App. 2008) — did not exist; citation led to In re Rodriguez, 248 S.W.3d 444 (Tex. App.—Dallas 2008, no pet.)
- Ex parte Clayton, 592 S.W.2d 494 (Tex. Crim. App. 1979) — did not exist; citation led to M.H. Siegfried Real Estate, Inc. v. Renfrow, 592 S.W.2d 488 (Mo. App. 1979)
- Ex parte Martinez, 340 S.W.3d 642 (Tex. Crim. App. 2011) — did not exist; citation led to Cochran v. Cochran, 340 S.W.3d 638 (Mo. App. 2011)
What the court said
“None of the three published cases cited actually exist in the Southwest Reporter.”
“Each citation provides the reader a jump-cite into the body of a different case that has nothing to do with the propositions cited by Lee.”
“These deficiencies, although brought to the Court's and to Lee's attention by the State in its brief to this Court, were neither contested nor corrected by Lee in any kind of reply, amended, or supplemental brief.”
“it appears that at least the “Argument” portion of the brief may have been prepared by artificial intelligence (AI).”
Timeline
- Trial court signed the order denying Lee’s habeas application for bail reduction.
- Court clerk warned counsel that noncompliant briefs would be stricken.
- Court of Appeals affirmed after holding the sole issue inadequately briefed.
Why this case matters
Ex parte Lee is an early state appellate entry in the tracker and it differs from Mata v Avianca in outcome. The court identified nonexistent Texas criminal cases and noted possible AI drafting, but it had no information explaining why the brief was illogical. It therefore declined both a show-cause order and a State Bar referral. That makes the record useful beside Morgan and Thomas: fabricated authorities can lead to waiver and affirmance even when no sanction follows. The opinion also preserves the State’s citation-by-citation check, showing exactly how reporter jump-cites to unrelated cases can make false authority look real.
Practice note
Appellate counsel should verify each cited case in the named reporter before filing and compare the cited page with the proposition in the brief. If the State flags invalid authorities, counsel should file a reply, amended brief or correction rather than leave the point uncontested. Any AI-drafted language needs a human check in print reporters or traditional legal databases before submission.
