The document summarizes the legal concept of automatism and provides examples of cases where the defense of automatism was used or rejected. It discusses the definition of automatism as an act done without control of the mind, such as a reflex. It then provides 3 rules from the Bailey case that determine when the defense can be used for specific vs. basic intent crimes and how recklessness affects the defense. Examples are given of cases where the defense was accepted, such as for post-traumatic stress or effects of medication, and rejected, such as for a condition causing partial loss of control.
