- Why the court cared
- Misrepresented: Case Law | Opening brief relied on an excerpt of Scripps Health (pp. 335–336) to assert threats must be immediate; the court explained the cited excerpt does not address that issue. || Fabricated: Case Law | Opening brief cited a non-existent case 'Montebello Unified School District v. State Board of Education (1991) 226 Cal.App.3d 1685'; counsel later conceded in a notice of errata that the citation does not appear to exist and attributed its inclusion to AI editing. || Fabricated: Case Law | Opening brief cited 'R.D. v. P.M. (2021) 68 Cal.App.5th 1012', a citation the County could not locate and the court concluded does not exist as presented. || Misrepresented: Case Law | Counsel misrepresented the holding of United States v. Rahimi, stating it invalidated a federal statute when Rahimi actually upheld the statute as applied in that case. || Misrepresented: Case Law | Counsel cited People v. Zermeno as supporting labor-speech protections and the proposition that strongly worded workplace criticism is protected, but Zermeno concerned gang-enhancement issues and does not support those propositions. || Misrepresented: Case Law | Brief cited Bookout v. Nielsen at page 1143 to claim reversal for lack of immediacy, but Bookout ends at page 1142 and the Court of Appeal affirmed the restraining order; counsel miscited and mischaracterized the case.
