Unchecked AI citations are getting expensive, and the bill is getting
personal. On September 25, 2026, Judge Angel Kelley of the District of
Massachusetts sanctioned a California lawyer, capped fees at $10,000
and revoked his permission to appear in the case, per the [court
order](https://docs.justia.com/cases/federal/district-courts/massachusetts/madce/1:2025cv12395/288446/155).
On October 9, 2026, Judge Katherine Polk Failla of the Southern
District of New York ordered a lawyer whose fake citations had already
cost his client the case to personally pay $38,877.59 to the opposing
lawyer who caught them.

## How Did a Rushed Brief End a Lawyer's Role in the Boston Case?

In Aguilar v. The Crawford Group, plaintiff's counsel Blake Lindemann
filed a 20-page opposition less than five hours after the defendants
filed their motion, according to the [court's
order](https://docs.justia.com/cases/federal/district-courts/massachusetts/madce/1:2025cv12395/288446/155).
Judge Kelley found that about half the citations in that brief
contained an error. It cited one First Circuit case six times for a
proposition the case does not support, attributed a quotation to a
fictitious Westlaw citation, and quoted cases for language they do not
contain. Later briefs repeated the problems, including a case the
court could not find on Westlaw, Lexis or Bloomberg.

Lindemann admitted using AI on the first brief and said he believed
the enterprise-level version of the tool he used did not hallucinate
cases. [Massachusetts Lawyers Weekly
reports](https://masslawyersweekly.com/2026/10/13/lawyer-ai-citations-pro-hac-vice-sanctions/)
that Lindemann described the tool as the "highest-grade enterprise
version of Claude." He also cited illness and a rush before vacation.
Anyone who has filed against a deadline will feel a flicker of
sympathy, but the court was not persuaded, noting that errors kept
appearing after defense counsel had flagged them by email and moved
for sanctions.

The judge was clear about where the line sits:

> "There is no rule against the use of AI in researching and drafting legal papers, but it must be utilized responsibly."

Lindemann's firm must pay the defendants' fees and costs for the
affected briefing, capped at $10,000, and his pro hac vice status is
revoked. The court did not sanction local counsel, because Lindemann
took sole responsibility, but it reminded him of his duty to supervise
out-of-state counsel.

## Why Did the New York Lawyer Have to Pay His Opponent?

In Flycatcher v. Affable Avenue, Judge Failla had already found in
February that defense counsel acted in bad faith by filing briefs with
fake AI-generated citations. As [Greenberg Traurig's eDiscovery Watch
summarizes](https://www.gtlaw-ediscoverywatch.com/2026/10/from-hallucination-to-sanctions-the-potential-costs-of-unverified-ai-citations/),
14 of the 60 cases in his motion to dismiss brief did not exist, and
the court struck his client's filings and entered default judgment.

The October 9 fee opinion awarded the plaintiff's lawyer who uncovered
the fake cases $38,877.59, payable by the offending lawyer personally.
The court found a $575 hourly rate reasonable, credited the time spent
investigating the fake citations, and cut the fees 10% because the
offending lawyer, a solo practitioner, had limited ability to pay. Its
reasoning: as AI citation problems spread, judges depend on opposing
counsel to catch them.

## What Are Judges Really Asking Lawyers?

Neither judge banned AI. Both just asked the question every partner
should ask: did you read the cases you cited? In Boston, the court
wrote that whether AI was used or not, the lawyer did not confirm his
citations. In New York, the court relied on the Second Circuit's rule
that lawyers must read the cases they cite.

Two details stand out if you manage litigators. The enterprise version
of a tool was no defense, so a business license is no guarantee of
accurate output. And the New York court paid the opponent who caught
the errors, which gives opposing counsel a financial reason to check
your citations.

## How Can Your Team Avoid Being the Next Order?

At a large firm, supervision is the exposure. The Boston order put
local counsel on notice, and partners who sign or sponsor briefs
drafted with AI can expect the same question about what they checked.

In-house litigation teams can ask outside counsel how they verify
AI-assisted citations before filing, and who signs off. A good answer
names a person and a step.

Small firms and solo practitioners carry the most risk, because there
is often no second reader. Build the cite check into the calendar, so
a deadline never forces the choice the Boston court described.

We rate this trend **Real**. Neither order creates a new rule, but the
costs are rising and landing on individual lawyers, so budget time to
check every citation, whatever tool drafted it.

## FAQ
