The sleepwalking defense is not applicable to which type of offenses?

• A. Strict liability offenses
• B. Civil offenses
• C. Misdemeanors
• D. Violations of probation

Answer: (A)

A sleepwalking defense rests on the absence of mens rea, the mental state needed to commit a crime. It only works for offenses that require a person to have intended or known that they were violating the law. Strict liability offenses, however, punish the prohibited act regardless of any mental state. The statute holds someone liable simply for the act itself, even if done while asleep or without awareness. Because there is no required mental state to prove, the sleepwalking defense cannot excuse liability in strict liability cases. Civil offenses aren’t crimes and don’t involve criminal defenses like automatism, so the defense wouldn’t apply there. In offenses that do involve a mental-state requirement, the defense could be more relevant, but for strict liability, the lack of mens rea makes the sleepwalking defense ineffective.
