criminal responsibility

a defendant’s ability to formulate criminal intent (see mens rea) at the time of the crime with which he or she is charged; it must be proved in court before the person can be convicted. Criminal responsibility may be excluded for reason of insanity (see Durham rule; irresistible impulse rule; M’Naghten rule) or mitigated for a number of other reasons (see diminished capacity; diminished responsibility).
