Ensuring Justice and Security: The Core Purpose of the Criminal Justice System

Every functioning democracy rests on one fundamental promise to its citizens: that the law will protect them, and that those who break it will be held accountable. In India, this promise is upheld – imperfectly, but persistently – by the Criminal Justice System (CJS). It is not a single institution but a network of agencies working in coordination: the police, the prosecution, the courts, and the correctional system. Understanding the core purpose of this system is the first step to understanding why it matters for every person in the country, not just lawyers or law enforcement officials.

What the criminal justice system is actually trying to do 🔗

At its most basic, the primary goals of the criminal justice system are to prevent and control crime, maintain public order and peace, protect the rights of victims and individuals involved in legal conflicts, punish and rehabilitate those found guilty, and safeguard life and property from criminal activity. These are not abstract ideals – they translate into concrete institutional functions every single day.

The system that deals with agencies of government responsible for enforcing the law, maintaining peace and harmony, and treating criminal conduct is known as the criminal justice system. Its aim is to ensure that every person who suffers injury or loss at the hands of others can present their case and seek justice. In simpler terms, it exists to answer three questions: Was a crime committed? Who is responsible? And what should happen next?

The four pillars carrying out the system’s purpose 🔗

India’s criminal justice system has four subsystems: the Legislature (Parliament), Enforcement (police), Adjudication (courts), and Corrections (prisons and community facilities). Each pillar has a specific function, and together they are meant to deliver end-to-end justice.

Police: the first responders to crime 🔗

The police are usually the first point of contact for anyone subjected to crime. Under Section 161 of the Code of Criminal Procedure, 1973, an investigating officer has the authority to question anyone who may possess information related to a case and record their statements. Their role is to investigate offences, gather evidence, and present accused persons before the court. The police serve the system’s protective purpose most directly – they are on the ground, responding to crime as it happens.

Prosecution: presenting the state’s case 🔗

Prosecutors formally charge individuals with crimes and attempt to establish guilt in a court of law. Importantly, in India’s adversarial system, the prosecutor represents the state – because a crime is considered an offence not just against one individual, but against society at large. The public prosecutor serves as a significant pillar of this system, with a duty to secure justice, not just convictions.

Courts: determining guilt and delivering justice 🔗

Courts sit at the centre of the CJS. They weigh evidence, hear arguments from both sides, and determine whether an accused person is guilty beyond a reasonable doubt. India follows the adversarial system inherited from British common law – a judge acts as a neutral fact-finder while prosecution and defence advocates argue before them. The system presumes the accused to be innocent until proven guilty, a cornerstone principle that protects individual liberty within the pursuit of justice.

Corrections: rehabilitation, not just punishment 🔗

Once a sentence is handed down, the correctional system – prisons and community facilities – takes over. Inmates in Indian prisons participate in programs aimed at reform and rehabilitation through education, vocational training, yoga, and meditation. The goal is to reintegrate offenders into society as functional citizens, reducing the likelihood of re-offending. Punishment alone has never been the end goal of a sound justice system.

Justice for both victims and offenders 🔗

One of the most important – and often overlooked – dimensions of the CJS’s purpose is the balance it must strike between the rights of the accused and the needs of the victim. This tension has been a subject of significant judicial and committee attention in India.

The Justice Malimath Committee, formed in 2000, submitted a report in 2003 with 158 recommendations, observing that the existing system placed too much weight on protecting the accused without adequately focusing on justice for victims. The Supreme Court and High Courts have since evolved remedies that go beyond punishment – including monetary compensation to victims. In one landmark ruling, a High Court held that the criminal justice system encompasses not just the penal code but also restitutive justice.

The landmark Hussainara Khatoon v. State of Bihar (1979) case brought the plight of undertrial prisoners to national attention when the Supreme Court found that thousands of individuals in Bihar jails had been detained for periods longer than the maximum sentence they could have received if convicted. The court ruled this a violation of the fundamental right to life under Article 21, making the case that justice delayed is justice denied – for victims and accused alike.

Maintaining societal order: the broader function 🔗

Beyond individual cases, the CJS serves a macro-level purpose: maintaining the social fabric. An efficient criminal justice system is critical for creating a society based on order and justice. When it functions well, it deters crime, assures people that wrongdoing will not go unchecked, and reinforces social trust. When it falters, the consequences are far-reaching.

Research shows that crime victimization significantly undermines trust in major public bodies, including politicians, justice-related institutions, and governments. The same research documents a negative spillover effect – local crime erodes public perception of institutions even among those who are not direct victims. Combating crime is therefore crucial not just for individual safety, but to restore citizen trust and enhance governance quality.

The real challenges standing in the way 🔗

Acknowledging the purpose of the CJS is one thing; recognising the gap between that purpose and reality is equally important. India’s system faces several persistent structural challenges.

Crime underreporting 🔗

A 2015 survey by the Commonwealth Human Rights Initiative found that approximately 53.2% of crime cases in Delhi and 58.2% in Mumbai went unreported. The reasons range from social stigma – particularly for gender-based crimes – to a simple lack of trust in the police. A practice known as “burking,” where police deliberately avoid registering FIRs to show lower crime rates, further distorts the picture. The Supreme Court addressed this directly in Lalita Kumari v. Govt. of Uttar Pradesh (2013), directing that registration of FIRs be made mandatory for cognisable offences.

Judicial delays and case backlog 🔗

As of September 2024, approximately 4.2 crore cases remain pending in various Indian courts, with criminal cases making up 33.4% of this backlog. Delays erode the deterrent effect of justice – if conviction takes years, the message to potential offenders is weakened. The conviction rate for rape stood at just 17.9%, while murder convictions came in at 42.5%, pointing to serious gaps in how effectively the system translates investigation into accountability.

Public trust deficit 🔗

Delayed trials, political interference, inefficient investigations, and low conviction rates hinder the timely delivery of justice and erode public trust. The police, in particular, face a colonial legacy of institutional mistrust that hampers their ability to gather evidence, secure witness cooperation, and perform investigations effectively. Without public trust, the system cannot fulfil its core mandate of protecting the community.

Recent reforms: shifting toward nyaya (justice) 🔗

India has taken significant steps to modernise its criminal justice framework. The Bharatiya Nyaya Sanhita (BNS), which came into effect on July 1, 2024, replaced the colonial-era Indian Penal Code of 1860. Alongside it, the Bharatiya Nagarik Suraksha Sanhita replaced the CrPC and the Bharatiya Sakshya Adhiniyam replaced the Indian Evidence Act.

The new laws place victims at the centre of the justice process – for instance, it is now mandatory that the victim be heard before prosecution is withdrawn. Community service has been introduced as a form of punishment for the first time, reflecting a shift from purely punitive to reformative justice. Zero FIRs, the ability to report crimes at any police station regardless of jurisdiction, and the acceptance of digital evidence on par with paper records are among the practical reforms aimed at making justice more accessible.

These changes signal a clear intent: to reorient the system from a punishment-first model to one that genuinely delivers nyaya – justice – to every citizen, whether victim or accused.

Why the purpose of the CJS matters beyond the courtroom 🔗

The criminal justice system’s purpose is not confined to prosecuting criminals. It shapes the quality of everyday life. A judicial backlog of over 4 crore pending cases delays justice and reduces deterrence against crime. Property values fall in high-crime areas. Investment retreats. Communities lose cohesion. The health of the CJS is, ultimately, an indicator of the health of the state itself.

Conversely, a system that works – that detects crime efficiently, prosecutes fairly, adjudicates promptly, and rehabilitates effectively – creates the conditions for people to live without fear. That sense of security is not a luxury; it is a basic right.

What do you think? Given the massive pendency of cases in Indian courts, should fast-tracking criminal trials be treated as a constitutional priority under the right to speedy justice? And with growing underreporting of crimes, what structural changes do you think would most effectively restore public trust in the police and the broader criminal justice system?
