A federal judge in Mississippi read the briefs on both sides of her courtroom, found fabricated cases on every one, and did something no court had done before: removed all four lawyers, plaintiff and defense, for trusting the same machine.
On June 8, 2026, Senior U.S. District Judge Sharion Aycock looked at the briefs filed on both sides of her courtroom and called one lawyer's conduct "a prime example of the risk associated with serving as a rubberstamp when acting as local counsel." Then she did something no federal judge had done before. She removed every attorney from the case. Plaintiff and defense. All four.
The case was Withers v. City of Aberdeen, a civil matter in the Northern District of Mississippi. It is the kind of docket that never makes headlines. It made one anyway.
The trouble was in the citations. Briefs from both sides leaned on cases that did not exist. The quotes were invented. The holdings were invented. The reporter volumes pointed nowhere. Aycock read them, checked them, and found the same fingerprint on filings from opposing camps that agreed on nothing else. Generative AI had written the law, and no human had checked whether the law was real.
Four lawyers signed those filings. Aycock named each one.
Kathleen M. Wilson, admitted pro hac vice from Louisiana, led for the plaintiff. Shauncey Hunter Ridgeway, a Mississippi attorney, served as her local counsel. Kathryn Y. Williams, admitted pro hac vice from Texas, led for the defense. Mark McClinton, also of Mississippi, was her local counsel. Two out-of-state specialists. Two in-state names on the signature block whose job was to stand behind the work.
That second job is where Aycock's anger settled. Local counsel exists so that someone licensed in the district vouches for what gets filed. The signature is a promise. Aycock found the promise empty. The local lawyers had passed the briefs through without reading the cases inside them. In an era of rampant unverified AI usage, she wrote, the rubberstamp is the risk.
The court did not accept the defense that nobody understood the tool. You do not get to sign a federal filing, put fabricated precedent in front of a judge, and then plead that the machine did it. The signature is yours. The duty to verify is yours. The machine has no bar card.

So Aycock priced the failure.
Wilson drew the heaviest fine, $3,500. Williams drew $2,500. The two local-counsel signatures, Ridgeway and McClinton, drew $1,000 apiece. The dollar figures are small. The next part is not.
Wilson and Williams, the two out-of-state lead attorneys, lost their pro hac vice status in the case and were barred from practicing in the Northern District of Mississippi for two years. A federal court closed its doors to them. Two years is a long time to explain to a client why you cannot appear in a district where their matter sits.
Read the order on the public docket and the symmetry is the story. Judges have sanctioned plaintiff lawyers for AI fabrications before. Judges have sanctioned defense lawyers for the same. What no court had done until June 8 was strike both sides of a single case in one order for the same sin. Aycock did not find a villain and a victim. She found a courtroom where every brief on the table was built on cases that were never decided.
A model wrote the law. A lead lawyer trusted it. A local lawyer signed it. A federal judge caught it.
The mechanism that failed is older than AI. Local counsel was the last human check, the licensed set of eyes that read what gets filed in a district court. That check was supposed to catch exactly this. It caught nothing. The briefs flowed up from a generative model, through an out-of-state lead, past a local name that signed without looking, and onto a federal judge's desk as if they were law.
The defense team here did not lose on the merits. It lost the right to appear. Outside counsel bills for judgment, for the human act of confirming that a cited holding exists and says what the brief claims it says. In Withers, that act never happened. The client's case caption now sits on a sanctions order, and the firm hired to protect that caption is the reason it is there.
The fines will be paid and forgotten. The two-year bar will not. Four lawyers walked into Withers v. City of Aberdeen on opposite sides. They walked out on the same one, removed by the same judge, for trusting the same machine. Aycock wrote the word that explains all of it. Rubberstamp. The court is closed to them now. The room is gone.
