Nipun Law Explained – Complete Guide to the New Indian Criminal Laws 2026
Complete explanation of the Nipun laws (Bharatiya Nyaya Sanhita, BNSS, and Bharatiya Sakshya Adhiniyam). Learn how the new criminal laws replace IPC, CrPC, and Evidence Act in India.
India has replaced its colonial-era criminal laws with three new comprehensive codes effective from 1 July 2024. The Bharatiya Nyaya Sanhita (BNS) replaces the IPC, the Bharatiya Nagarik Suraksha Sanhita (BNSS) replaces the CrPC, and the Bharatiya Sakshya Adhiniyam (BSA) replaces the Indian Evidence Act.
The three new laws represent the most significant overhaul of India's criminal justice system since independence. The reforms aim to make laws more relevant to contemporary challenges, speed up justice delivery, and prioritize the rights of victims. The laws were passed by Parliament in December 2023 and came into effect from 1 July 2024.
In Kolkata, all courts including the Calcutta High Court, Bankshall Court, and subordinate courts now operate under these new laws.
Bharatiya Nyaya Sanhita (BNS) 2023
The BNS replaces the Indian Penal Code (IPC) of 1860. With 358 sections (down from 511 in IPC), the BNS simplifies and modernizes criminal offences. Key changes include: community service as a punishment, separate offences for organized crime and terrorism, expanded definition of rape to include digital evidence, and stricter punishment for crimes against women and children.
The BNS introduces new offences including organized crime (Section 111), petty organized crime (Section 112), and the use of a deadly weapon during snatching (Section 304).
Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023
The BNSS replaces the Code of Criminal Procedure (CrPC) of 1973. Key changes include: mandatory forensic investigation for offences punishable with 7+ years, timeline for investigation (60-90 days depending on the offence), videography of search and seizure proceedings, and provision for summary trial of petty cases.
The BNSS also introduces the concept of zero FIR (FIR can be filed at any police station regardless of jurisdiction), electronic summons, and mandatory audio-video recording of statements of victims of sexual offences.
Bharatiya Sakshya Adhiniyam (BSA) 2023
The BSA replaces the Indian Evidence Act of 1872. The new law expands the definition of evidence to include electronic records, digital documents, and electronic communications. Electronic records are now treated as primary evidence (not secondary as under the old law).
The BSA also provides for admissibility of call detail records, messages, emails, and server logs as evidence if accompanied by a certificate under Section 63.
Key Changes for Kolkata Litigants
Zero FIR: File FIR at any Kolkata police station irrespective of jurisdiction
Electronic evidence: WhatsApp messages, emails, and call records are now primary evidence
Forensic mandatory: Crime scene forensic examination mandatory for all serious offences
Timelines: Police must complete investigation within 60-90 days

Understanding Your Legal Rights Under the Constitution
The Constitution of India guarantees fundamental rights to all citizens under Part III. These rights include the right to equality (Article 14), right to freedom (Article 19), right to life and personal liberty (Article 21), right against exploitation (Articles 23-24), right to freedom of religion (Articles 25-28), cultural and educational rights (Articles 29-30), and the right to constitutional remedies (Article 32). These rights form the bedrock of India's democratic legal system.
Article 21, the right to life and personal liberty, has been interpreted expansively by the Supreme Court and the Calcutta High Court to include the right to live with dignity, right to health, right to a clean environment, right to livelihood, right to privacy, and right to speedy trial. This provision has been the foundation of numerous landmark judgments that have expanded the scope of individual rights in India.
In Kolkata, the Calcutta High Court has been particularly active in protecting fundamental rights. Through its writ jurisdiction under Article 226, the High Court can issue writs of habeas corpus, mandamus, prohibition, certiorari, and quo warranto to enforce fundamental rights and other legal rights. Citizens who believe their rights have been violated can approach the High Court directly for relief.
◆ Fundamental rights can be enforced directly in the Supreme Court under Article 32
◆ The Calcutta High Court can issue writs under Article 226 for any legal right, not just fundamental rights
◆ Rights are not absolute and can be subject to reasonable restrictions in the interest of public order
◆ The right to information under the RTI Act is a statutory right that complements fundamental rights
◆ Public Interest Litigation (PIL) can be filed to enforce the rights of disadvantaged groups
Legal Remedies When Your Rights Are Violated
When your legal rights are violated, the Indian legal system provides multiple avenues for redress. The most common remedy is filing a case before the appropriate court. For criminal violations, you can file an FIR at the local police station or file a criminal complaint before a Magistrate. For civil violations, you can file a civil suit seeking damages, injunction, or specific performance.
In addition to court remedies, there are specialized tribunals and authorities that handle specific types of violations. For example, the National Human Rights Commission (NHRC) and the West Bengal State Human Rights Commission handle complaints of human rights violations. The Consumer Disputes Redressal Commissions handle consumer rights violations. The Labour Courts handle employment-related disputes.
Kolkata has a well-developed ecosystem of legal aid services. The West Bengal State Legal Services Authority (WBSLSA) provides free legal aid to eligible persons. The Kolkata District Legal Services Authority (KDLSA) operates out of the Alipore Court complex and provides legal aid, mediation services, and legal awareness programs. Our legal team can guide you to the appropriate authority for your specific grievance.

Under the Hindu Marriage Act, 1955, the grounds for divorce include adultery, cruelty, desertion, conversion to another religion, unsoundness of mind, leprosy, venereal disease, renunciation of the world, and presumption of death. The Act also provides for divorce by mutual consent under Section 13B.
Under the Special Marriage Act, 1954, which applies to interfaith marriages and civil marriages, the grounds for divorce are similar but also include the fact that the parties have not cohabited as husband and wife for a period of one year or more after a decree of judicial separation. The Indian Divorce Act, 1869 governs divorce for Christians, while the Parsi Marriage and Divorce Act, 1936 applies to Parsis.
Muslim law provides for different modes of divorce including talaq (unilateral divorce by the husband), khula (divorce at the instance of the wife with her consent), mubarat (divorce by mutual consent), and judicial divorce under the Dissolution of Muslim Marriages Act, 1939. The grounds for judicial divorce for Muslim women include the husband's impotence, cruelty, desertion, failure to maintain, and imprisonment.
◆ Divorce by mutual consent requires a minimum waiting period of 6 months (can be waived by the court)
◆ The court must attempt reconciliation before granting a contested divorce
◆ Adultery as a ground for divorce requires proof of both opportunity and inclination
◆ Cruelty can be physical, mental, or emotional, and includes verbal abuse and harassment
