Federal Court Suspends a Pennsylvania Lawyer Six Months for AI-Fabricated Citations
In Twigg v. BSN Sports, Chief Judge Matthew W. Brann of the Middle District of Pennsylvania fined a plaintiff's lawyer $1,500 and suspended him from practice in that court for six months over AI-generated citations that did not exist, finding a violation of Rule 11.
The story of AI sanctions has had one predictable shape for two years. A lawyer files a brief with citations invented by a chatbot, the court catches it, and the penalty is a few thousand dollars and a lecture. Everyone winces, nobody's license is touched, and the practice continues. The Middle District of Pennsylvania has now changed the shape. Chief Judge Matthew W. Brann did fine the attorney, but the fine was almost beside the point at $1,500. What he added is the part that should stop a room: a six-month suspension from practicing before the court. That is not a cost of doing business. That is the court telling a lawyer he cannot appear.
The underlying conduct is by now familiar. As reported in the Legal Intelligencer, the court found the attorney had "violated Rule 11 by submitting fabricated and inaccurate case citations." Rule 11 is the provision that makes your signature on a filing a certification to the court that your legal contentions are warranted and that you have done the diligence to back them. Fabricated citations break that certification at its root, because the lawyer is representing that authorities exist and say things when they do not exist at all.
Why does a six-month suspension matter more than the fine?
Because a fine ends when you pay it and a suspension does not. A monetary sanction is absorbed, sometimes by the firm, and forgotten. A suspension from a federal court is a professional-record event. It has to be disclosed on other bar applications and pro hac vice motions, it can trigger reciprocal discipline inquiries in the lawyer's home jurisdiction, and it sits in the public docket where opposing counsel and future clients can find it. When courts move from fining conduct to suspending over it, they are reclassifying that conduct from careless to serious. That is exactly the reclassification happening to AI fabrication in real time.
What pushed the court past a fine?
Two threads run through these escalating orders, and both appear here. The first is the fabrication itself, which courts increasingly view not as an accident but as a failure to do the most basic thing a signing lawyer must do, which is confirm that the cases cited are real. The second is what the lawyer does when caught. According to the reporting, Judge Brann was unimpressed by the attorney's effort to shift responsibility for the citations onto the tool rather than owning the filing he signed. That posture, "the AI did it," is precisely the argument that turns a manageable sanction into a severe one. The court does not care that a model produced the text. The lawyer signed it.
Is this binding on other courts?
State the ceiling plainly. This is a trial-court sanctions order. It binds the parties and the attorney in front of Judge Brann, it suspends him from that specific court, and it rests on a Rule 11 finding. It is not a Third Circuit opinion that every district must follow. So do not overstate it as new circuit law. What it is, and this is the useful part, is another rung on a ladder the whole federal bench is climbing. Read alongside six-figure fines elsewhere and multi-year bar sanctions in other states, the Pennsylvania order shows that the range of consequences for AI fabrication now runs all the way to losing your ability to practice.
What should a litigator take from this?
The duty has not moved, only the stakes. Verify every citation you sign against the real reporter, read the holding, and confirm every quotation against the actual text before the brief goes out. Treat any AI-drafted research as an unverified starting point that must be checked case by case, never as authority you can rely on. And drop the instinct to blame the tool if something slips. The one argument that consistently makes these outcomes worse is the one that tries to move responsibility off the person who signed the filing. Own the verification, build it into your process, and keep a record that you did it. The Pennsylvania order is the clearest sign yet that the alternative is no longer just expensive. It can be disqualifying.
Questions professionals are asking
What sanction did the court impose?
Chief Judge Matthew W. Brann fined the attorney $1,500 and suspended him from practicing before the U.S. District Court for the Middle District of Pennsylvania for six months, based on a finding that he violated Rule 11 by submitting fabricated and inaccurate case citations generated with AI.
Why is a suspension a bigger deal than a fine?
A fine ends when it is paid. A suspension is a professional-record event. It must be disclosed on other bar and pro hac vice applications, it can trigger reciprocal discipline in the lawyer's home jurisdiction, and it sits in the public docket. Moving from fining conduct to suspending over it reclassifies that conduct from careless to serious.
Does this decision bind other courts?
No. It is a trial-court sanctions order that binds the parties and the attorney before that judge and suspends him from that specific court. It is not a Third Circuit opinion of general application. It is significant as part of a clear trend toward harsher remedies for AI fabrication across the federal bench.
Does blaming the AI tool help?
No, and it tends to make things worse. Reporting indicates the judge was unimpressed by the attorney's attempt to shift responsibility onto the tool. Rule 11 attaches to the person who signs the filing. Courts consistently treat the "the AI did it" defense as a reason to escalate, not to excuse.
