## 📖 Dataset Summary

This dataset contains **1,059 fully structured and verified sections** extracted, parsed, and unified from India's three landmark criminal justice reform acts passed in December 2023. These three acts together replaced the colonial-era Indian Penal Code (IPC, 1860), the Code of Criminal Procedure (CrPC, 1973), and the Indian Evidence Act (IEA, 1872). They received Presidential assent on **December 25, 2023** and came into force on **July 1, 2024** — representing the most sweeping overhaul of India's criminal justice system in over 150 years. They are named as 2023 acts because that is the year of their parliamentary passage and enactment.

> [!IMPORTANT]
> **Verified Accuracy:** This dataset contains exactly **1,059 unified sections** mapping the complete current framework of modern Indian criminal law across all three acts, structured in a consistent JSON schema designed for immediate use in RAG pipelines, fine-tuning workflows, and legal NLP research.

<div align="center">

| Act | Full Name | 🔄 Replaces | 📚 Chapters | 📄 Sections |
| :--- | :--- | :--- | :---: | :---: |
| **BNS 2023** | Bharatiya Nyaya Sanhita, 2023 | Indian Penal Code, 1860 | 20 | 358 |
| **BNSS 2023** | Bharatiya Nagarik Suraksha Sanhita, 2023 | Code of Criminal Procedure, 1973 | 39 | 531 |
| **BSA 2023** | Bharatiya Sakshya Adhiniyam, 2023 | Indian Evidence Act, 1872 | 12 | 170 |
| **Total** | | | **71** | **1,059** |

</div>

All three acts operate together in every criminal case in India. The **BNS** defines what constitutes a crime and prescribes the punishment for it. The **BNSS** governs the entire criminal procedure from FIR registration through investigation, bail, charge, trial, judgment, and execution of sentence. The **BSA** determines what evidence is admissible in court and how it must be proved. This dataset unifies all 1,059 sections from all three acts into a single consistent machine-readable JSON format.

---

## 🏛️ Background: Why These Acts Matter

India's criminal justice system was governed for over 160 years by three laws written under British colonial administration. The Indian Penal Code (1860) defined crimes, the Code of Criminal Procedure (1973) governed how those crimes were investigated and tried, and the Indian Evidence Act (1872) governed what could be presented as proof in court.

The BNS, BNSS, and BSA were passed by the Parliament of India in the Winter Session of December 2023. They modernize the criminal justice framework by introducing:

- ⚖️ Provisions for organised crime and terrorism as distinct offences
- 💻 Electronic records recognized as **primary evidence** (not secondary)
- ⏱️ Mandatory timelines for investigation and trial completion
- 🤝 Community service introduced as a form of punishment
- 📋 Zero FIR provisions allowing registration at any police station regardless of jurisdiction
- 🆔 Updated definitions of offences to reflect 21st-century realities

For AI and NLP researchers, legal technologists, and developers building Indian legal AI systems, these three acts are the foundational texts of modern Indian criminal law and the correct source for any system targeting the current legal framework.

## 🗂️ Dataset Structure

### JSON Schema

Each of the 1,059 entries is a JSON object with the following structure:

```json
{
  "chunk_id": "BNS_101",
  "text": "[Context: This section is from BNS 2023, CHAPTER VI OF OFFENCES AFFECTING THE HUMAN BODY. It covers Section 101: Murder.]\n\n101. Murder.— Except in the cases hereinafter excepted, culpable homicide is murder,—\n(a) if the act by which the death is caused is done with the intention of causing death; or\n(b) if the act by which the death is caused is done with the intention of causing such bodily injury as the offender knows to be likely to cause the death of the person to whom the harm is caused; or\n...",
  "section_number": "101",
  "section_title": "Murder",
  "chapter": "CHAPTER VI OF OFFENCES AFFECTING THE HUMAN BODY",
  "act": "BNS 2023",
  "source_label": "Section 101, BNS 2023"
}
```

### 📋 Field Descriptions

| Field | Type | Description |
| :--- | :---: | :--- |
| `chunk_id` | string | Unique identifier in format `ACT_SectionNumber`. BNS: `BNS_1`→`BNS_358`. BNSS: `BNSS_1`→`BNSS_531`. BSA: `BSA_1`→`BSA_170`. Prefixed per act, not globally sequential. |
| `text` | string | Complete self-contained section text. Includes a prepended context header identifying the act and chapter, followed by the full section body with all sub-clauses, illustrations, exceptions, explanations, and provisos. Primary content field. |
| `section_number` | string | Official section number as it appears in the act (e.g., `"101"`, `"47"`, `"3"`). |
| `section_title` | string | Official title of the section as it appears in the act (e.g., `"Murder"`, `"Arrest without warrant"`). |
| `chapter` | string | Full chapter heading under which this section falls within its respective act. |
| `act` | string | Source act. Exactly one of: `"BNS 2023"`, `"BNSS 2023"`, or `"BSA 2023"`. |
| `source_label` | string | Human-readable citation string (e.g., `"Section 101, BNS 2023"`). Designed for direct use as a citation tag in RAG outputs. |

### 🧱 Text Field Design

Every `text` field is intentionally structured with a context header prepended before the section content, making each chunk fully self-contained for RAG pipelines:

```
[Context: This section is from BNS 2023, CHAPTER VI OF OFFENCES AFFECTING THE HUMAN BODY.
It covers Section 101: Murder.]

101. Murder.— Except in the cases hereinafter excepted, culpable homicide is murder,—
(a) if the act by which the death is caused is done with the intention of causing death; or
(b) if the act by which the death is caused is done with the intention of causing such bodily
injury as the offender knows to be likely to cause the death of the person to whom the harm is caused; or
...
Exception 1.— Culpable homicide is not murder if the offender, whilst deprived of the power of
self-control by grave and sudden provocation...
Illustration.
(a) A shoots Z with the intention of killing him. Z dies in consequence. A commits murder.
```

## 🎯 Intended Uses

> [!NOTE]
> This dataset was built with three primary use cases in mind — RAG pipelines, fine-tuning, and multi-agent legal AI systems.

**🔍 RAG Systems for Indian Legal Q&A**
Each chunk is fully self-contained with its context header, making it directly usable with embedding models such as `BAAI/bge-base-en-v1.5`, `sentence-transformers/all-MiniLM-L6-v2`, or `intfloat/multilingual-e5-base`, and vector databases such as ChromaDB, FAISS, Pinecone, LanceDB, or Weaviate. The `source_label` field is designed for direct use as a citation tag in generated outputs.

**🤖 Fine-tuning Legal Language Models**
The structured format with section titles, chapter context, act attribution, and full legal text including illustrations and exceptions is well-suited for generating synthetic instruction-response pairs for supervised fine-tuning (SFT) of small language models on Indian criminal law.

**🕸️ Legal AI Agents and Multi-Agent Systems**
The per-act structure enables building multi-agent systems where specialized agents handle different aspects of a legal query — a BNS agent for crime identification and punishment, a BNSS agent for procedural guidance, and a BSA agent for evidence requirements.

**📊 Legal NLP Research**
Section classification, legal named entity recognition, cross-act relationship mapping, legal question answering, and Indian criminal law language modeling.

**📚 Legal Education and Reference Tools**
Building tools that help law students, legal aid workers, journalists, and citizens understand the new criminal laws of India.

> [!WARNING]
> This dataset is intended for research, education, and development purposes only. It must not be used as a substitute for qualified legal advice. The dataset represents the text of the acts as extracted via automated PDF parsing and may contain minor formatting artifacts. Users should verify critical legal text against the official Government of India Gazette notifications.

## 🔧 Source and Parsing Methodology

**Source:** Official text of BNS 2023, Bharatiya Nagarik Suraksha Sanhita 2023, and Bharatiya Sakshya Adhiniyam 2023 as published by the Government of India.

**Enactment timeline:** All three acts were passed by the Parliament of India in the Winter Session of December 2023. They received Presidential assent on December 25, 2023. They are named as 2023 acts because that is the year of parliamentary passage and enactment. They came into force on **July 1, 2024**, replacing the IPC, CrPC, and IEA from that date.

**Parsing methodology:** PDF documents were parsed using `pdfplumber` for text extraction. Section boundaries were identified using rule-based chunking that detects section number patterns in the extracted text. Each section was extracted with its complete content including all sub-clauses, illustrations, exceptions, explanations, and provisos. A context header was prepended to each chunk for RAG compatibility. All 1,059 sections across the three acts were validated for completeness and correct attribution before final export to JSON.
