Crimes and punishments; persons liable for punishment; modifying list of exceptions; effective date.

HB 3890 amends Oklahoma's criminal code to update the legal definition of who is exempt from criminal liability due to specific circumstances. It revises the list of exceptions (such as for children under 14, individuals with intellectual disabilities or mental illness who couldn't understand wrongfulness, and those acting under involuntary subjection) without adding new categories. The bill takes effect on November 1, 2026, and affects criminal cases where defendants may claim these specific exemptions.
