Evidence; artificial intelligence expert testimony; effective date.

HB 2016 amends Oklahoma evidence law to establish specific standards for admitting and challenging artificial intelligence system outputs as testimony in court. It requires the party introducing AI-generated evidence (the "proponent") to demonstrate it meets four criteria: it helps the court understand evidence, uses reliable data, applies sound methods, and reflects consistent reliability. The bill also treats AI outputs similarly to human hearsay statements, allowing parties to challenge their accuracy using evidence like inconsistent prior outputs. This law applies directly to courts, lawyers, and parties in legal cases using AI systems, effective November 1, 2025.
