Civil proceedings; duties of attorneys and legal advisor; duties concerning exhibits believed to be false, misleading, or manipulated; sanctions or disciplinary action; effective date.
Summary
HB4348 would update Oklahoma law governing attorneys and civil pretrial practice to address false, misleading, or manipulated evidence, including material altered or generated by artificial intelligence. It amends the attorney-duty statute to expressly prohibit lawyers from knowingly encouraging, introducing, or producing such evidence without disclosure, and it adds a duty to exercise reasonable diligence to verify the authenticity of evidence before offering it to the court. The bill also bars attorneys from knowingly citing fictitious court authorities.
In civil actions, the bill authorizes district courts to hold pretrial conferences or hearings focused on the authenticity and admissibility of exhibits. It requires parties to raise concerns if they reasonably suspect an opponent’s exhibits are falsified, misleading, or manipulated, and it requires disclosure when a party knows or has reason to know its own exhibits are affected. If an attorney offers evidence without disclosure after failing to use reasonable diligence, the court may impose sanctions, and the Supreme Court may pursue disciplinary action. The bill would take effect November 1, 2026.
Impact
The bill would amend 5 O.S. 2021, Section 3, and 12 O.S. 2021, Section 2016, creating explicit statutory duties for attorneys and litigants in civil cases regarding AI-generated or otherwise manipulated evidence. It would expand pretrial procedure to allow courts to address exhibit authenticity before trial and would give courts and the Supreme Court additional enforcement tools through sanctions and professional discipline. The practical effect is to impose clearer disclosure and verification obligations on lawyers and parties handling digital or potentially synthetic evidence.
Sentiment
Based on the bill text and available context, the measure appears to be framed as a professional-integrity and court-process safeguard rather than a controversial policy change. There is no recorded committee debate or vote history in the provided materials, so no formal opposition or support is documented. The overall tone of the bill is preventive and regulatory, reflecting concern about the growing use of artificial intelligence in litigation and the need to preserve evidentiary reliability.
Contention
The main potential point of contention is the scope and enforceability of the new diligence and disclosure requirements, especially the standard of what an attorney “should have known” or what constitutes reasonable suspicion that evidence is manipulated. Another possible issue is how courts will distinguish ordinary evidentiary disputes from AI-related falsification, and whether the sanctions and disciplinary provisions could chill advocacy or increase pretrial litigation over authenticity. No specific opposing or supporting groups are identified in the available record.
