Global Sentencing Standards: How International Norms Shape Justice

Every time a judge pronounces a sentence in a criminal court, that moment is shaped not just by national law, but also by a wider web of international norms and standards. These global frameworks – developed over decades through the United Nations and multilateral treaties – set the floor for how states must treat offenders, what punishments are permissible, and how the most vulnerable groups like juveniles deserve special protection. For law students in India, understanding these international norms is essential, because they directly inform constitutional values, judicial reasoning, and the ongoing evolution of India’s criminal justice system.

Why international sentencing norms matter 🔗

Sentencing is perhaps the most consequential stage of any criminal proceeding. Yet for a long time, it was treated as purely a domestic affair – each country doing as it saw fit. The post-World War II era changed that. The establishment of the United Nations and the adoption of binding human rights treaties created a shared global language for justice. States began accepting obligations to treat offenders with dignity, to limit the use of harsh punishments, and to pursue rehabilitation over mere retribution. These are not abstract ideals – they are codified norms that courts and legislators are expected to follow.

The International Covenant on Civil and Political Rights (ICCPR) 🔗

The cornerstone of international human rights law as it relates to criminal justice is the International Covenant on Civil and Political Rights (ICCPR), adopted by the UN General Assembly on 16 December 1966 and entering into force on 23 March 1976. India ratified the ICCPR in 1979 and is therefore bound by its provisions.

From a sentencing standpoint, several ICCPR articles are directly relevant. Article 6 protects the right to life and strictly limits the application of the death penalty – it may only be imposed for the “most serious crimes” and cannot be applied retroactively. Article 7 absolutely prohibits torture and cruel, inhuman, or degrading treatment or punishment. Article 10 requires that all persons deprived of liberty be treated with humanity and dignity. It explicitly mandates that prisons focus on reform and rehabilitation rather than punishment alone. Article 14 guarantees fair trial rights, including the right to appeal a conviction or sentence to a higher tribunal. Article 15 prohibits retrospective criminal penalties and requires the imposition of the lesser sentence where laws have changed between the time of the offence and conviction.

Compliance with the ICCPR is monitored by the UN Human Rights Committee, which reviews state reports and holds governments accountable for how these rights are implemented in practice.

The Second Optional Protocol: pushing towards abolition of the death penalty 🔗

While Article 6 of the ICCPR permits the death penalty under strict conditions, many states have gone further by ratifying the Second Optional Protocol to the ICCPR, which was adopted on 15 December 1989 and entered into force on 11 July 1991. States that ratify this Protocol commit themselves to completely abolishing the death penalty. As of December 2024, 92 states have ratified it.

The Protocol leaves virtually no room for exceptions. Article 2 permits only one reservation – states may retain capital punishment for the most serious military crimes committed during wartime, and even that must be declared at the time of ratification. The UN Human Rights Committee has consistently stressed that the death penalty in practice frequently involves violations of other ICCPR rights, including fair trial guarantees and the prohibition of torture.

India’s position: India has not ratified the Second Optional Protocol. India remains a retentionist country, meaning it retains the death penalty in law. Indian courts award capital punishment for a narrow category of crimes, but only in the “rarest of rare” cases – a judicially evolved standard that, while not abolishing the penalty, reflects an attempt to limit its use in the spirit of international norms.

The Convention Against Torture (CAT) 🔗

The Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (CAT), adopted in 1984 and in force since 1987, is a critical international instrument that directly shapes sentencing norms. CAT prohibits any form of torture – not just as a method of investigation, but also as a form of punishment. This has concrete implications for sentencing: sentences that involve corporal punishment, or prison conditions that amount to degrading treatment, are inconsistent with CAT standards.

CAT also reinforces the prohibition on extraditing or deporting a person to a country where they face a real risk of torture. The CAT Committee, which monitors compliance, has frequently flagged concerns about countries that set the age of criminal responsibility too low, as subjecting very young children to the criminal process can itself amount to degrading treatment.

India signed CAT in 1997 but has not ratified it. Nevertheless, the principles of CAT are reflected in Indian constitutional protections – Article 21 of the Constitution of India, which guarantees the right to life and personal liberty, has been interpreted by the Supreme Court to prohibit inhuman or degrading treatment in custody.

The Tokyo Rules: rethinking imprisonment 🔗

A landmark UN instrument that has directly shaped modern sentencing philosophy is the United Nations Standard Minimum Rules for Non-Custodial Measures, adopted by the UN General Assembly in 1990. Named after the city where discussions originated, they are popularly called the Tokyo Rules.

The core premise of the Tokyo Rules is straightforward: imprisonment causes harm, and wherever possible, alternative measures should be preferred. The Rules call on criminal justice systems to develop a wide range of non-custodial options – from pre-trial diversion and bail, to probation, community service, suspended sentences, and conditional release at the post-sentencing stage. Pre-trial detention is to be used as a measure of last resort, and any non-custodial measure selected must be tailored to the offender’s background, the gravity of the offence, and the needs of society.

The Tokyo Rules also emphasise non-discrimination: they must be applied without distinction based on race, sex, age, religion, national origin, or any other status. Supervision of offenders placed on non-custodial measures must aim at reducing reoffending and facilitating reintegration into society, not mere surveillance. The Rules explicitly state that imprisonment should be reserved for more serious and dangerous offenders – a principle that directly challenges the tendency in many legal systems to default to incarceration.

For India, the Tokyo Rules are relevant in the context of ongoing debates about prison overcrowding, undertrials, and the excessive use of remand custody. The Juvenile Justice (Care and Protection of Children) Act, 2015 and the expansion of bail reforms reflect the influence of these principles in domestic law.

The Beijing Rules: a dedicated framework for juvenile sentencing 🔗

When the accused is a minor, a separate – and more protective – set of international standards applies. The United Nations Standard Minimum Rules for the Administration of Juvenile Justice, adopted by the UN General Assembly on 29 November 1985, are known as the Beijing Rules after the city where they were discussed during preparatory meetings.

The Beijing Rules start from the premise that juveniles are fundamentally different from adult offenders – their characters are not fully formed, they are more susceptible to rehabilitation, and the stigma of formal conviction can itself cause lasting harm. The Rules accordingly call for a strong preference for diversion – removing young offenders from the formal criminal justice process altogether wherever possible, and redirecting them to community-based support. Where formal proceedings do occur, they must be conducted in an atmosphere of understanding that allows the juvenile to participate meaningfully.

Sentencing principles for juveniles under the Beijing Rules 🔗

Rule 17 of the Beijing Rules sets out detailed principles for sentencing. The guiding idea is proportionality – the response must be proportionate to the offence and to the circumstances of the offender. Importantly, capital punishment is expressly prohibited for any offence committed by a juvenile, a standard consistent with Article 6(5) of the ICCPR. Corporal punishment is also absolutely prohibited, in alignment with Article 7 of the ICCPR and the Convention Against Torture.

Probation is strongly preferred over institutional placement. The Rules ask that juveniles be placed in closed institutions only as a last resort and for the shortest possible period. Even where institutional placement occurs, the focus must be on educational and correctional goals – not punishment. Deprivation of liberty for a juvenile should be a disposition of last resort and limited to exceptional cases, with the length of any sentence determined by the judicial authority.

India’s Juvenile Justice (Care and Protection of Children) Act, 2015 was modelled significantly on the Beijing Rules. The Act created Juvenile Justice Boards for adjudicating cases involving children in conflict with the law, emphasising rehabilitation and reintegration over punitive sentencing. Even when a child above sixteen is tried as an adult for heinous offences, the Act retains procedural safeguards inspired by these international norms.

How these norms interact with Indian law 🔗

India occupies an interesting position in relation to these international instruments. It has ratified the ICCPR and the Convention on the Rights of the Child (CRC), incorporated many of these principles into domestic legislation, but has not ratified CAT or the Second Optional Protocol. This creates a partial alignment – Indian courts regularly invoke international human rights norms as persuasive authority in interpreting fundamental rights under the Constitution, even when the specific treaty has not been ratified.

The Supreme Court of India has, over the decades, used ICCPR provisions and the broader framework of UN rules to expand the content of Article 21. Cases dealing with prison conditions, undertrials, the death penalty, and juvenile justice have all drawn from this international reservoir of norms. The Court’s development of the “rarest of rare” doctrine for capital punishment, for instance, resonates with the ICCPR’s requirement that the death penalty be restricted to only the most serious crimes.

Key takeaways for law students 🔗

Understanding international sentencing norms is not just an academic exercise. These instruments – the ICCPR, the Second Optional Protocol, CAT, the Tokyo Rules, and the Beijing Rules – collectively represent the global consensus on what humane, fair, and proportionate justice looks like. They reflect a shift away from purely punitive models of sentencing toward frameworks that prioritise rehabilitation, dignity, and community reintegration. India’s domestic law has absorbed many of these principles, but gaps remain – particularly around the death penalty, the ratification of CAT, and the treatment of undertrials. As future legal professionals, engaging critically with these gaps is part of what makes the study of criminal justice both urgent and meaningful.

What do you think? India has ratified the ICCPR but continues to retain the death penalty and has not ratified the Second Optional Protocol – does the “rarest of rare” doctrine adequately bridge this gap between international norms and domestic practice? And given the Tokyo Rules’ strong preference for non-custodial measures, how should India address the persistent problem of undertrial overcrowding in its prisons?
