A Fort Lee attorney in New Jersey was recently fined $3,000 after submitting fake legal citations generated by AI. The federal court ruling sends a strong warning to all lawyers about relying on AI without verification.
On September 18, Magistrate Judge José R. Almonte sanctioned attorney Sukjin Henry Cho for including non-existent case law in his court filings. Cho admitted that he used AI tools alongside traditional legal research databases.
The Risks of Using AI in Legal Research
Judge Almonte highlighted the growing issue of AI misuse in courts, stating that AI can produce citations that appear authentic but are completely fabricated.
“AI made it up. And those who rely on AI blindly, do so at their own peril,” the judge said.
Legal professionals often cite previous court rulings to support arguments. Fake or unverified citations can mislead judges, breach ethical standards, and result in sanctions against attorneys.
Attorney’s Response and Preventive Measures
Cho explained in court filings that he relied on AI-assisted tools along with LexisNexis searches due to tight deadlines. He has now implemented stricter internal safeguards to prevent future errors.
The court acknowledged Cho’s prompt admission, apology, and corrective measures, but also referenced past incidents where lawyers were fined $1,000 to $6,000 for submitting AI-generated fake case law.
Court Ruling and Requirements
Judge Almonte determined that a $3,000 fine was appropriate to deter future misuse. Cho is required to:
- Pay the fine within 14 days
- Notify his client about the sanction
- Self-report the sanctions to the state bar authorities
Cho has declined to comment publicly on the ruling.
