Why this matter is tracked
In this contract dispute, the California Court of Appeal affirmed a $32,314.34 judgment against a pro se appellant. The court found the appellant's brief relied on numerous fabricated case citations and misattributed quotations. The court noted that while it suspected the use of artificial intelligence to generate these invalid authorities, it declined to issue sanctions at this stage, noting the respondent did not participate in the appeal. The court emphasized that pro se litigants are held to the same procedural standards as attorneys and that citing nonexistent authority violates California Rules of Court, rule 8.204(a)(1)(B). The judgment was affirmed due to the appellant's failure to provide an adequate record to demonstrate trial court error.
