Mithu v. State of Punjab

Supreme Court of India · 1983 · 1983 AIR 473; 1983 SCR (2) 690

This judgment struck down a law that automatically sentenced certain life-term prisoners to death for any murder committed in custody, without letting a judge weigh the circumstances. It reinforced that courts must always have the power to consider whether death is truly the appropriate punishment, rather than having it imposed as an automatic rule. This protected the fundamental right to a fair and individualized sentencing process, even for the most serious crimes.

The story

The facts

Mithu, a prisoner already undergoing a sentence of life imprisonment, was convicted of murdering another person while in custody. Under Section 303 of the Indian Penal Code, murder committed by a person under sentence of life imprisonment carried a mandatory death penalty, with no judicial discretion to impose any lesser sentence. Mithu challenged the constitutional validity of Section 303, arguing it violated his fundamental rights. The case was referred to a Constitution Bench given its significance following the earlier ruling in Bachan Singh v. State of Punjab.

The question before the court

Whether Section 303 IPC, which mandates a death sentence for murder committed by a person already under sentence of life imprisonment (removing all judicial discretion in sentencing), is constitutionally valid under Articles 14 and 21 of the Constitution.

The holding

A five-judge Constitution Bench unanimously struck down Section 303 IPC as unconstitutional. The Court held that the provision violated Articles 14 and 21 because it imposed a mandatory death sentence without permitting the judge to consider the facts and circumstances of the crime or the criminal, thereby denying a fair and reasonable sentencing procedure. The Court reasoned that if even in cases of murder simpliciter under Section 302, the death penalty could only be imposed in the 'rarest of rare' cases after weighing aggravating and mitigating circumstances (per Bachan Singh), it was wholly arbitrary and unjust to impose a mandatory death sentence merely because the accused was already serving a life sentence, without any judicial discretion whatsoever.

The principle it stands for

A statute prescribing a mandatory death penalty, which forecloses all judicial discretion to consider the circumstances of the offence and the offender before sentencing, offends the guarantee of a fair, just and reasonable procedure under Article 21 and the equality principle under Article 14. Sentencing discretion in capital cases, as mandated by Bachan Singh's 'rarest of rare' doctrine, is a constitutional necessity and cannot be legislatively excluded.
