In California was the first state where the diminished capacity defense recognized first time in the case People v. Wells [13]
Insanity and diminished responsibility defense are linked at their ideological hip by men rea. So in order to understand the concept of diminished responsibility firstly, I should have to discuss the insanity defense. As in Pakistan we have the insanity defense for the accused that are suffered from some sort of mental illness and not diminished responsibility defense. At the end of this dissertation paper I will give some suggestion to amend the law on insanity with respect to diminished responsibility.
The concept of “not guilty by reason of insanity” was first time introduced in the era of Prophet (PBUH).
