What happened

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.
