INCIDENT TYPE UNVERIFIED
AI OUTPUT
CASE SUMMARY

A court filing prepared with assistance from generative AI contained citation and quotation errors that were not adequately verified before the filing was submitted.

CASE Hill v. Foundation Media LLC
COURT U.S. District Court
Southern District of New York
AI TOOL Harvey
LAW FIRM Shapiro Arato Bach LLP
JUDGE Arun Subramanian
OUTCOME No sanctions imposed
INCIDENT RECORD 01.01

The incident arose in Hill v. Foundation Media LLC, a copyright case in federal court in New York. Attorneys representing Foundation Media submitted a filing that contained problems with legal citations and quotations. The court questioned whether unchecked use of artificial intelligence had contributed to those errors (Scarcella, 2026).

Cynthia Arato, an attorney representing Foundation Media, later told the court that another lawyer at Shapiro Arato Bach had prepared the initial draft and finalized the filing. According to Arato, the lawyer failed to properly verify AI-generated material before submission. The firm subsequently disclosed that tools developed by Harvey had been used to assist in preparing the filing (Scarcella, 2026).

Judge Arun Subramanian ultimately declined to sanction the attorneys, but used the incident to warn about relying on AI-generated legal work without careful human review. His September 29, 2026 order emphasized that citations, quotations, and legal propositions produced with AI assistance must be checked for accuracy (Hill v. Foundation Media LLC, 2026).

CASE 1728 INCIDENT RECONSTRUCTION / DOCUMENT 03

03 / WHAT WENT WRONG

Reconstruct the
failure.

ANALYSIS PROCESS
FAILURE
RECONSTRUCTION

The incident was not the result of a single action. The available records show a sequence in which AI-assisted legal work moved through the drafting process without adequate verification before reaching the court (Scarcella, 2026).

CASE 1728 / FAILURE POINT

WHAT WENT
WRONG?

FAILURE POINT HUMAN
VERIFICATION

AI-assisted material passed through the professional workflow without being adequately checked before submission.

INCIDENT RECONSTRUCTION CASE 1728
03.01
RECONSTRUCTION FINDING The critical checkpoint was verification.

The available evidence points to a breakdown between AI-assisted drafting and final human review. The technology produced or assisted with material that required verification, but the professional workflow failed to catch the problems before submission (Scarcella, 2026).

CASE STATUS NO
SANCTIONS
AFTER DISCOVERY

Once the citation and quotation problems were brought before the court, the incident shifted from a filing error into a broader examination of professional responsibility, AI safeguards, and the role of human review.

01
COURT REVIEW SEPT. 2026

The errors were questioned.

The court identified problems involving citations and quotations in Foundation Media's filing and questioned whether unchecked use of artificial intelligence had contributed to them (Scarcella, 2026).

COURT INTERVENTION
02
FIRM RESPONSE COURT RECORD

The firm responded.

Cynthia Arato apologized to the court and explained that another lawyer at Shapiro Arato Bach had worked on the initial draft and finalization of the filing. Her declaration stated that the AI-generated citations had not been properly verified (Scarcella, 2026).

EXPLANATION SUBMITTED
03
COURT DECISION SEPT. 29, 2026

The judge declined sanctions.

Judge Arun Subramanian decided that no further action would be taken against the attorneys. However, he described the incident as a "wakeup call" and emphasized that AI-assisted legal work must still be carefully checked by lawyers (Hill v. Foundation Media LLC, 2026).

NO FURTHER ACTION
04
RESPONSE & SAFEGUARDS AFTER INCIDENT

New safeguards were promised.

Arato stated that the conduct was contrary to the firm's existing policies and training and that additional safeguards would be implemented following the incident (Scarcella, 2026).

PROCESS REVIEW
04.01
THE WARNING WENT BEYOND THIS CASE

AI accuracy was only part of the concern.

Judge Subramanian also raised a longer-term concern: increasing reliance on AI could interfere with the development of junior lawyers if they no longer gain experience researching, reasoning through, and drafting legal arguments themselves (Hill v. Foundation Media LLC, 2026).

ANALYSIS
ANALYST NOTE

The following section represents my personal assessment of the incident based on the evidence presented throughout this case file.

05.01 / PRIMARY FINDING
The failure was not using AI. The failure was trusting its output without verification.
MY ANALYSIS CASE
1728
PERSONAL ASSESSMENT

In terms of the problem revolving around this case, it wasn't the use of AI but the misuse of it by taking it at it's word, even though the Harvey AI platform is designed specifically for use within the legal system it doesn't mean it's perfect and this isn't the only instance of this happening (RAGbase Legal Research Team, 2026). There are multiple examples like Mata v. Avianca, Inc where AI made up cases that were used to file legal motions (Goswami, 2023). and the only way to fix this is through the use of human verification. Verification is one of the core tenants of proper AI usage and it could've avoided many situations like these if someone took the time to verify the validity of the information provided by AI.

05.02 / THE CHECKPOINT

AI output should be a starting point.

01 GENERATE Use AI to assist with research or drafting.
→
02 QUESTION Treat the output as information to evaluate.
→
03 VERIFY Check claims against reliable sources.
→
04 USE Only rely on information after verification.
05.03
CONNECTION / PROMPTING PLAYBOOK

Verification is part of using AI well.

This incident directly connects to the verification principle in my AI Prompting Playbook. Regardless of how specialized or capable an AI system may be, its output still needs to be checked before it is relied upon.

FINAL ASSESSMENT CASE 1728

AI can assist the work. It cannot replace responsibility for the work.
