Case Law Analysis On Plea Of Insanity In Nepalese Courts
1. Introduction: Plea of Insanity in Nepalese Criminal Law
The plea of insanity is a legal defense where an accused claims they were mentally incapable of understanding the nature or wrongfulness of their acts at the time of committing a crime.
Legal Basis in Nepal
Nepal Penal Code, 2017
Section 16: Criminal liability requires mens rea (intention).
Section 16(2): Persons who cannot understand the nature of the act or distinguish right from wrong due to mental illness are exempt from criminal liability.
Criminal Procedure Code, 2017
Sections 134–135: Procedure for medical evaluation in cases of alleged insanity.
Constitutional Protection
Article 16: Right to personal liberty and fair trial ensures proper medical and legal evaluation.
Key Principles
Burden of proof: Accused must prove insanity at the time of the offense.
Medical evaluation: Psychiatric assessment is crucial.
Partial vs. total insanity: Full insanity may absolve liability; partial may mitigate sentence.
State protection: Even if exempted from punishment, courts may order institutionalization for public safety.
