J.D. v. Superior Court

Court of Appeal of California, Fifth Appellate District · Cal. Ct. App. · California bar guidance

Conduct

A father's writ petition quoted Welfare and Institutions Code section 350(b) for a proposition the statute does not contain; the court could not verify any source for the quoted text.

Consequence

No sanction. The court reminded counsel that knowingly presenting nonexistent statutory authority violates the duty of candor and may lead to sanctions reportable to the State Bar.

Lesson

Here the court checked a quoted statute against its text, and warned that knowledge of presenting nonexistent authority may be inferred from the circumstances.

Summary

A father, J.D., petitioned for an extraordinary writ under California Rules of Court, rule 8.452, challenging a Kern County juvenile court order that terminated his reunification services and set a Welfare and Institutions Code section 366.26 hearing for his two children. He argued he had not received proper notice of the Kern County Department of Human Services' recommendation because the report deadline should have been extended for out-of-state mailing. To support that extension, the petition quoted Welfare and Institutions Code section 350, subdivision (b), as providing that, "Except where otherwise provided by this code, the procedures for the trials or hearings shall be in accordance with that prescribed by law for civil cases." The court wrote: "Section 350, subdivision (b) does not so provide, and we have been unable to verify the legal source for this quotation." The father also relied on Code of Civil Procedure section 1013, subdivision (a), which the court held does not apply in dependency proceedings absent an express provision. The opinion lists David G. Duket of the Law Office of David G. Duket as counsel for the petitioner. It does not mention artificial intelligence.

What did the court warn about?

In a nonpublished opinion by the court (Franson, Acting P. J., Meehan, J., and Snauffer, J.), the Fifth Appellate District denied the petition and the request to stay the section 366.26 hearing, holding that substantial evidence supported the finding that notice was proper, that any notice defect was harmless given the father's lack of contact with the department, and that reasonable services were provided. On the quotation, footnote 3 states that "Counsel is reminded" of the duty under rule 3.3(a)(1) of the Rules of Professional Conduct and Business and Professions Code section 6068, subdivision (d), not to knowingly make a false statement of law, that "[t]his duty is violated when counsel knowingly presents statutory authority to the court that does not exist," and that knowledge "may be inferred from the circumstances." It adds that nonexistent authority may be treated as a matter "not reasonably material to the appeal's determination" under rule 8.276(a)(2), and that failure to adhere to these standards "may result in sanctions which themselves may be mandatorily reportable to the California State Bar." The court imposed no sanction.

Why does J.D. v. Superior Court matter for law firms using AI?

J.D. v. Superior Court is a dependency writ in which the defective authority was a statute, not a case. The father argued that out-of-state mailing should have added time to the 10-day deadline for the department’s report in Welfare and Institutions Code section 366.21, subdivision (c). His petition bridged the dependency statutes to the Code of Civil Procedure’s mailing extension by quoting section 350, subdivision (b), as saying hearings follow the procedures “prescribed by law for civil cases.” The court checked the statute and found that it “does not so provide,” adding that it had “been unable to verify the legal source for this quotation.”

The court then decided the notice argument on the merits. It held that dependency proceedings are special proceedings to which the Code of Civil Procedure does not apply unless the Welfare and Institutions Code says so, that substantial evidence supported the juvenile court’s notice finding, and that any defect was harmless under In re A.D. because the father had not maintained contact or participated meaningfully in his case plan. It also rejected his reasonable-services challenge and denied the petition and the requested stay.

The response to the quotation sits in footnote 3. The court reminded counsel of the duty not to knowingly make a false statement of law to a tribunal, said the duty is violated when counsel knowingly presents statutory authority that does not exist, and noted that knowledge may be inferred from the circumstances. It did not find that counsel acted knowingly, did not mention AI, and imposed no sanction. Firms documenting compliance may wish to consider that, in this case, the court framed an unverifiable statutory quotation as a candor issue and pointed to the State Bar reporting consequences a sanction could carry.

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.

  • Verify every quotation of a statute against the official code text. Here the court found that section 350, subdivision (b) "does not so provide" and that it was "unable to verify the legal source" of the quoted language.
  • Review rule 8.452 writ petitions with the same citation checks as full appeals. This petition challenged an order setting a section 366.26 hearing, and the court still addressed the unverifiable quotation in a footnote.
  • Consider that the court tied its reminder to rule 3.3(a)(1) and Business and Professions Code section 6068, subdivision (d), and noted that sanctions may be mandatorily reportable to the State Bar under section 6068, subdivision (o)(3).

Primary sources

Unverified claims:
  • AI attribution is a Charlotin tracker inference ("Implied"). The opinion says only that section 350, subdivision (b) "does not so provide" and that the court could not verify the source of the quotation; it does not mention AI or explain how the quotation came to be in the petition.
  • The footnote 3 reminder is addressed to "Counsel" without a name. The entry identifies David G. Duket only as the attorney the opinion lists for the petitioner, whose petition contained the quotation; the opinion does not otherwise name who drafted it.
