Criminal law in India is the foundation of public order, safety, and justice. It protects society from harm by deterring wrongful acts and penalizing offenders. Understanding these laws helps citizens recognize their legal rights and avoid legal violations. This blog details what is criminal law, its purpose, major laws and examples to provide a comprehensive understanding.

What is Criminal Law?

Criminal law deals with offences that harm public order or societal interests. These laws address both minor and serious offences such as robbery, rape, and murder, as recognised by legislation. It imposes penalties such as fines, imprisonment, and the death penalty to regulate criminal justice procedures. Criminal law empowers the state to prosecute offenders on behalf of society and impose penalties.

Why Criminal Laws Exist?

Criminal law helps maintain social order and ensure justice for citizens across India's diverse population. It fosters trust in governance among its citizens by providing fair trials. The purpose of criminal law is also to support victims by providing restitution and holding offenders accountable. Recent reforms addressing cybercrime threats and refining offence categorisations have strengthened the criminal laws in India.

Major Criminal Laws in India

The importance of criminal law in India lies in its ability to maintain order, deter crime, and ensure justice through codified statutes. These statutes include the Indian Penal Code (IPC), the Criminal Procedure Code (CrPC), and the Indian Evidence Act. They have been replaced by the Bharatiya Nyaya Sanhita (BNS), the Bharatiya Nagarik Suraksha Sanhita (BNSS), and the Bharatiya Sakshya Adhiniyam (BSA), which came into force on July 1, 2024.

Below is the list of criminal law in India:

  • The Bharatiya Nyaya Sanhita (BNS)

The Bharatiya Nyaya Sanhita is the new criminal code that replaces the Indian Penal Code, 1860. The BNS modernizes India’s legal framework by restructuring the definitions of offences and punishments. The law formally recognizes and penalizes new offenses such as petty organized crime and organized crime syndicates.

  • The Bharatiya Nagarik Suraksha Sanhita (BNSS)

The Bharatiya Nagarik Suraksha Sanhita is the new law that replaces the Criminal Procedure Code 1973. It provides procedures for prosecution, arrest, bail, investigation, and trials. The law requires a forensic investigation to be mandatory for all crimes punishable by a jail sentence of seven years or more.

  • The Bharatiya Sakshya Adhiniyam (BSA)

The Bharatiya Sakshya Adhiniyam replaces the Indian Evidence Act. The purpose of the BSA is to transform how evidence is handled in the nation. This new law accepts electronic records, including emails, electronically recorded spoken testimony, device-saved files, messages, and location data.

Types of Crimes in India

Crimes in India are broadly classified into several main categories based on the nature of the offence and the harm caused. Below are the primary types of crimes in India:

Crimes Categorised Under the Bharatiya Nyaya Sanhita (BNS)

  • Bailable: Minor crimes with bail as a right
  • Non-Bailable: Serious crimes requiring court discretion for bail
  • Cognizable: The police can arrest the suspect without a warrant for these crimes, e.g., murder.
  • Non-Cognizable: These crimes require a magistrate's order for arrest, e.g., defamation.
  • Compoundable: These are less serious offences where the victim can reach a private settlement with the accused, e.g., minor assault, petty theft.
  • Non-Compoundable: The state must prosecute in these cases, e.g. murder, rape.

Classification of Crimes Based on Their Nature

  • Offences against the human body: Includes murder, homicide, rape, kidnapping, and assault.
  • Offences against women and children: Rape, acid attacks, stalking, child abandonment.
  • Property crimes: Includes theft, robbery, burglary, dacoity, and criminal breach of trust.
  • Crimes against the state/public: Sedition, waging war, offences against public tranquillity.
  • White-collar crimes: Financial crimes such as fraud, insider trading, and corruption.

Cybercrimes, economic offences, and terrorism are also major types of crimes in India.

Criminal Law vs Civil Law: Key Differences

This section explores the criminal law vs civil law differences. Civil laws handle disputes between individuals seeking compensation from the offender. This includes offences like breach of contract, personal injury, family matters (divorce, custody), and property disputes. Most of the time, resolutions for these cases are settled with monetary remedies.

Criminal laws deal with offences against the state. These include murder, theft, assault, fraud, drug offences, and cybercrimes. Penalties for civil laws include fines, imprisonment, and the death penalty. Criminal law requires a higher standard of proof than civil law, because it punishes offences against society and can lead to imprisonment.

Key Examples of Criminal Laws

Below are some examples of criminal law and the offences:

  • Murder (Section 103): Intentionally causing death is a non-bailable offence punishable by death or life imprisonment.
  • Rape (Section 63): Non-consensual sexual intercourse can lead to penalties of life imprisonment or death. In aggravated cases (e.g., gang rape of minors), emphasis is on victim rights and fast-track trials.​
  • Organised crime (Section 111): Syndicate-based acts like kidnapping, extortion, cyber-crimes, or trafficking can lead to death or life imprisonment with a fine starting from β‚Ή5 lakh.
  • Terrorism (new provision): Acts threatening national unity, security, or public terror are punishable by death or life imprisonment with fine.
  • Mob lynching (Section 103 (2)): Murder or grievous hurt by five or more persons on grounds of caste, race, or belief can lead to death or life imprisonment plus fine.​
  • Petty organised crime: Gang-based theft, pick-pocketing, or exam paper leaks;1-7 years imprisonment plus a fine, harsher than individual acts.​

Conclusion
