Bixler v. Church of Scientology International

California Court of Appeal, Second Appellate District, Division Five · Cal. Ct. App. · California bar guidance

Conduct

Here counsel conceded the respondents' brief was prepared with AI tools; the court's order cited appellants' count of at least ten authorities miscited or mischaracterized.

Consequence

The Court of Appeal gave notice it was considering monetary sanctions; its opinion did not address them, and the register of actions shows no ruling on the notice.

Lesson

Here the conceded citation errors drew a formal sanctions notice, but the register shows no ruling on it before the appeal ended.

Summary

Chrissie Carnell Bixler and four other plaintiffs sued the Church of Scientology International and others; the defendants appealed the denial of their anti-SLAPP motions. The plaintiffs, as respondents, filed their brief on July 30, 2025, through Boies Schiller Flexner LLP and John Kucera. On February 19, 2026, the court filed an order stating that respondents' counsel "have conceded as follows: counsel prepared the Brief of Respondents, filed on July 30, 2025, with the aid of artificial intelligence tools; controls and policies to protect against the risk of improper use of those tools failed; and the filed brief included material citation errors that were correctly identified by appellants in their reply brief." The order added that appellants' reply brief "specifically identifies (in Attachment A at pages 41-48) at least ten purported case authorities that have been miscited or mischaracterized in more than fifteen places in respondents' brief." Earlier, on September 19, 2025, respondents had moved for leave to file a corrected brief; appellants opposed, the Association of Southern California Defense Counsel applied to file an amicus letter opposing it, and on November 21, 2025 the court denied both the motion and the application. The docket entries do not state the court's reasons for that denial.

How did the court address the AI-related conduct?

The February 19 order gave respondents' counsel notice under California Rules of Court, rule 8.276(c), "that the court is considering the imposition of monetary sanctions on respondents' counsel for the foregoing conduct," citing Noland v. Land of the Free, Schlichter v. Kennedy, Shayan v. Shakib, and rules 8.276(a)(4), 8.204(a)(1)(B), and 8.1115(a). Respondents could oppose within 10 days, and sanctions were to be argued with the merits. The docket shows respondents' response filed March 2, 2026, argument on March 3, and Kucera's withdrawal as counsel on March 9. The court's unpublished opinion of May 19, 2026 modified the order to grant the anti-SLAPP motions as to two short passages, affirmed as modified, and ordered each side to bear its own costs. The opinion does not mention sanctions, the citation errors, or artificial intelligence, and the full register of actions shows no order ruling on the notice; its only later reference is an April 1, 2026 notice of change of address for Kucera "limited to sanctions order." The court denied appellants' rehearing petition on June 15, 2026; the California Supreme Court denied review (S297235) on August 12, 2026; and the remittitur issued on September 8, 2026.

Why does Bixler v. Church of Scientology International matter for law firms using AI?

The only court act on the citations in Bixler is the February 19, 2026 order, and its substance is a concession rather than a finding. The order records that respondents’ counsel conceded three things: that the respondents’ brief was prepared “with the aid of artificial intelligence tools,” that “controls and policies to protect against the risk of improper use of those tools failed,” and that the brief “included material citation errors that were correctly identified by appellants in their reply brief.” It then quantified the problem by reference to the appellants’ reply: at least ten purported authorities “miscited or mischaracterized in more than fifteen places.” The order does not itself list the authorities, and it names no AI tool.

The court proceeded under the California Rules of Court rather than a free-standing order to show cause. It gave notice under rule 8.276(c) that it was “considering the imposition of monetary sanctions on respondents’ counsel,” invited an opposition within 10 days, and set the question for argument with the merits. Among its authorities it cited three 2025 Court of Appeal decisions (Noland v. Land of the Free, Schlichter v. Kennedy, and Shayan v. Shakib) and three rules, described in its own brackets as covering “sanctions for unreasonable violations of rules of court,” “failure to support contentions with citations to legal authority,” and the “prohibition on citing unpublished authority.” The order does not say which of the miscited authorities implicated which rule.

The court then did not rule on the notice. Its May 19, 2026 opinion decided the anti-SLAPP appeal, largely in the respondents’ favor, with each side bearing its own costs, and it says nothing about sanctions or the brief. Rehearing and review were denied and the remittitur has issued, so on this record no ruling on the notice appears and no reasons are stated. Firms documenting compliance may wish to consider that, here, a conceded failure of AI-use controls put a firm’s counsel under a formal sanctions notice through argument, even though the court ultimately did not act on it.

Implications for your firm

Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.

  • Document the controls that govern AI-assisted drafting. Here the court's order recited counsel's concession that "controls and policies to protect against the risk of improper use of those tools failed."
  • Review an opponent's catalog of citation errors promptly. The court's order relied on an attachment to appellants' reply brief that identified the miscited and mischaracterized authorities.
  • Consider that a motion to replace a filed brief may be denied. Here the court denied respondents' September 2025 motion for leave to file a corrected brief; the docket gives no reason and does not say what the correction addressed.
  • Consider that an appellate sanctions notice under rule 8.276(c) can be argued with the merits. Here the notice set sanctions for argument at the merits hearing.

Unverified claims:
  • The AI concession is as recited in the court's February 19, 2026 order; counsel's own filings (the September 19, 2025 motion for leave to file a corrected brief and the March 2, 2026 response to the sanctions notice) were not read, and no AI tool is named anywhere read.
  • Whether and why the court resolved the sanctions notice is unknown: the May 19, 2026 opinion is silent on it, and the full register of actions (read 2026-09-30) shows no order resolving it. An April 1, 2026 entry records a change-of-address notice for former counsel Kucera "limited to sanctions order," which the register does not explain.
  • The Charlotin tracker says the sanctions question was before the California Supreme Court; the Supreme Court docket shows the petition for review (S297235) denied on August 12, 2026, and does not state the issues presented, which were not verified.
