MS HB1337

Requires all new criminal offenses enacted after July 1, 2015 to specify the degree of mental culpability (intent) required for commission; any offense failing to specify culpability is void from the beginning

Defines four levels of culpable mental states: purposely (specific intention), knowingly (awareness conduct will probably cause result), recklessly (heedless indifference to substantial risk), and negligently (failure to perceive risk due to lapse in due care)

Establishes that when a statute neither specifies culpability nor indicates strict liability, the default standard is recklessness for elements related to knowledge or intent

Allows strict criminal liability only when a statute plainly indicates that purpose and does not specify any degree of culpability

Provides that voluntary intoxication cannot be used as a defense to negate the mental state element of a crime, though evidence of intoxication may show physical incapacity to perform an act
