Description: California immigration attorneys Mike Singh Sethi and William Rounds were reportedly sanctioned in LNU v. Blanche after Ninth Circuit filings included purportedly fabricated and materially inaccurate legal authorities. The court said unauthorized generative AI use by unlicensed brief writers was probable and found that the attorneys failed to verify the filings and repeatedly lacked candor about the errors' source.
Editor Notes: Timeline note: The incident ID date is 10/20/2025, based on the oral argument at which the Ninth Circuit examined the purportedly fabricated citations and possible generative AI use because the briefs' exact filing date has not been established. A disciplinary order filed on 06/03/2026 detailed the probable AI involvement and imposed sanctions. The incident ID was created on 07/06/2026.
