HB2538: Providing an exception to criminal liability when a defendant has a mental disease or defect so as not to know the nature of the act or that such act was wrong.

• The bill would provide an exception to criminal liability for defendants with a mental disease or defect that affects their understanding of the act's nature or wrongfulness. • This exception would apply only when the defendant has a mental condition that prevents them from knowing the nature of their actions or that they're doing something wrong. • The bill does not specify what constitutes a 'mental disease or defect' or how it would be determined in court.
