Capital Punishment: Law and Debate (UGC-NET Unit VII)

For NET purposes, start with the split between retentionist and abolitionist states. A retentionist state keeps capital punishment in law and continues to use it for a narrow range of the most serious offences, almost always aggravated murder, and in some states also terrorism, treason or drug trafficking.

An abolitionist state has removed the penalty from law, or has not carried out an execution for so long that monitoring bodies such as Amnesty International classify it as abolitionist in practice even though the statute remains on the books.

The shift toward abolition is recent and uneven. Most of the world's states have exited the practice, concentrated from the 1960s onward and accelerating after 1990 as post-communist and Latin American states joined regional human rights treaties conditioning membership on abolition. A smaller, persistent minority, including some of the world's most populous countries, continues to retain and use the penalty.

Remember the pairing for MCQs: retentionist equals keeps and uses; abolitionist equals removed in law, or unused long enough to count as abolitionist in practice.

Three arguments support retention. The retributive argument holds that a person who has taken a life, especially with cruelty or premeditation, deserves a proportionate punishment, and that for the most extreme crimes only death is proportionate. This is a backward-looking desert claim, not a prediction about future crime. The incapacitative argument holds that execution removes any possibility the offender kills again, whether after release, escape, or inside prison against guards and other inmates.

The third and most contested argument is the deterrence hypothesis: that the prospect of execution deters potential murderers more effectively than the prospect of life imprisonment. Unlike the other two, this claim is empirical and can in principle be tested against crime data. It is also the argument criminologists treat with the greatest scepticism, for reasons the next section develops, even though retentionist governments invoke it regularly in public debate around especially violent crimes.

The abolitionist case begins with irreversibility. Every other criminal sanction can be partially remedied if a conviction is later overturned, since the wrongly imprisoned person can be released and, in many systems, compensated. An execution forecloses that remedy entirely. Because no criminal justice system has a zero error rate, abolitionists argue a punishment with no possibility of correction is incompatible with a fallible system.

Wrongful conviction is not hypothetical. Records kept in the United States, such as the National Registry of Exonerations, document death-row prisoners exonerated after new forensic testing, recanted testimony, or the discovery that prosecutors withheld exculpatory evidence, some after decades on death row. Abolitionists also point to arbitrariness and discrimination in how the sentence is applied in practice, arguing it falls disproportionately on the poor and on racial or religious minorities rather than tracking the objective severity of the offence.

The deterrence question has been studied for decades without producing reliable support for the hypothesis. A 2012 review by the National Research Council concluded that existing studies were not informative about whether capital punishment affects homicide rates, largely because researchers cannot isolate a deterrent effect from confounding factors such as clearance rates and the very low probability that any given murder results in execution.

Comparative data point the same way: jurisdictions that abolished the penalty generally saw homicide trends continue similarly to neighbouring retentionist jurisdictions, with no clear divergence attributable to the change in law.

International law has moved toward abolition alongside this evidence. The ICCPR Second Optional Protocol was adopted by the United Nations General Assembly in 1989; India, along with the United States and China, has not ratified it.

India's own sentencing law follows the rarest of rare doctrine from Bachan Singh v. State of Punjab (1980): a court may impose death only after weighing aggravating and mitigating circumstances and finding that life imprisonment is unquestionably foreclosed, a standard now applied under the Bharatiya Nyaya Sanhita, 2023.
