Courts cracking down on error-strewn AI-assisted legal briefs

Several federal and state courts are implementing new requirements for attorneys to disclose the use of generative AI in their legal filings. These measures follow a series of incidents where lawyers submitted briefs containing fake case citations and fabricated legal precedents produced by large language models. The rules aim to ensure professional accountability and preserve the integrity of court records by forcing legal practitioners to certify that human oversight has verified all cited information.
