 Introduction Fingerprints are one of the most reliable forms of forensic evidence used in criminal investigations. Since every individual has unique fingerprints, their development and preservation are essential for identifying suspects and solving crimes. Various scientific methods are used to make latent (invisible) fingerprints visible on different surfaces. These methods are broadly classified into physical and chemical techniques. Key Points at a Glance • Fingerprint development is essential for crime investigation • Methods are classified into physical and chemical techniques • Choice of method depends on the surface type • Modern technology has improved accuracy in fingerprint detection Meaning of Fingerprint Development Fingerprint development refers to the process of making latent fingerprints visible so that they can be photographed, preserved, and analyzed. Latent prints are usually invisible to the naked eye and require special techniques to be detected. The selection ...

Introduction Fingerprint examination is one of the most reliable methods of personal identification in forensic science. The scientific study of fingerprints used to identify individuals is called dactyloscopy. Fingerprints are unique, permanent, and universal, making them a powerful tool in criminal investigations. Fundamental Principles of Fingerprints Fingerprint science is based on the following principles: 1. Individuality (Uniqueness):  No two individuals have identical fingerprints. Each fingerprint pattern is unique. 2. Permanence: Fingerprints develop in the womb around the third month and remain unchanged until death. 3. Persistence: Fingerprint ridge patterns remain stable throughout life. 4. Classifiability: Fingerprints can be systematically classified into different patterns for identification. 👉 A minimum of 8–9 matching points is generally required for fingerprint identification. Personal Identification through Fingerprints Fingerprint identification is widely used...

Introduction The concept of Burden of Proof is a fundamental principle of evidence law. Under the Bharatiya Sakshya Adhiniyam, 2023, the burden of proof determines which party is legally bound to prove a fact in court. In criminal as well as civil cases, the success or failure of a case largely depends upon the proper discharge of this burden. The law relating to burden of proof ensures fairness in trials and prevents arbitrary convictions. What is Burden of Proof? In simple terms, burden of proof means the obligation to prove a fact. It lies on the party who asserts the existence of a fact. If a person makes an allegation, that person must prove it. If he fails to do so, the court will not accept the claim. There are two essential aspects: 1. Burden of proof as a matter of law 2. Burden of proof as a matter of fact (onus probandi) General Principle of Burden of Proof The basic rule is: “He who asserts must prove.” In criminal cases, the prosecution carries the burden to prove the guil...

Introduction The principle embodied in Res Gestae is contained under Section 6 of the Bharatiya Sakshya Adhiniyam, 2023, which corresponds to Section 6 of the Indian Evidence Act, 1872. The term Res Gestae is derived from Latin, meaning “things done”. This doctrine forms an exception to the rule against hearsay evidence. Ordinarily, hearsay evidence is inadmissible; however, statements or acts that form part of the same transaction are admissible because they are considered spontaneous and closely connected with the main fact in issue. Meaning of Res Gestae Res Gestae includes those facts, declarations, or acts which are so intimately connected with the main occurrence that they form part of the same transaction. Such statements are admitted not because they are declarations, but because they are natural, spontaneous, and contemporaneous reactions to the event. Scope of Section 6 (BSA) According to Section 6, facts forming part of the same transaction are relevant, whether they occurre...

 (Previously under the Indian Evidence Act, 1872) Introduction The law of evidence plays a crucial role in the administration of justice. It determines which facts may be proved before a court and how such facts are to be established. Under Indian law, the concept of relevancy of facts forms the foundation of evidentiary rules. With the repeal of the Indian Evidence Act, 1872, the law relating to evidence is now governed by the Bharatiya Sakshya Adhiniyam, 2023 (BSA). Although the structure of the law remains largely similar, it has been modernised to meet contemporary legal requirements. Meaning of Relevancy of Facts A fact is said to be relevant when it has a logical connection with the fact in issue and helps the court in arriving at a conclusion. Not all facts are admissible in evidence; only those facts which are relevant under the provisions of the Bharatiya Sakshya Adhiniyam may be proved. Relevancy acts as a filter, ensuring that only meaningful and connected facts are plac...

Introduction to Bharatiya Sakshya Adhiniyam, 2023 The Bharatiya Sakshya Adhiniyam, 2023 (BSA) is India’s new evidence law governing the admissibility, relevance and proof of evidence in judicial proceedings. It replaces the Indian Evidence Act, 1872 which was in force for over 150 years. This new statute modernizes and codifies principles of evidence law to reflect developments in technology, electronic evidence, and contemporary judicial needs. However, many foundational concepts from the old Evidence Act are still valid and integrated into the new law. Why a New Evidence Law Was Needed Before the new law was enacted: ● Evidence rules were based on a colonial-era statute (IEA 1872) ● Modern scientific evidence (digital data, cloud storage, metadata) lacked clear statutory recognition ● Courts had to rely on judicial interpretation to admit electronic evidence The new law now consolidates: ✔ Traditional evidence rules ✔ Technology-driven evidence (digital, electronic) ✔ Contemporary ev...

Introduction Crime Scene Investigation (CSI) is a systematic process used to preserve, document, collect, and analyze physical evidence from a crime scene. The 7 S’s of Crime Scene Investigation provide a scientific and legal framework to ensure evidence is not contaminated and remains admissible in court. 7 S’s of Crime Scene Investigation 1. Securing the Scene Securing the crime scene is the responsibility of the first responding police officer (first responder). Key Points: ● Safety of individuals is the first priority ● Preservation of evidence is the second priority ● Unauthorized persons must be restricted from entering the crime scene ● A security log must be maintained of everyone who enters the scene ● The first responder may call additional expert teams if required 2. Separating the Witnesses Witnesses must be separated immediately after the incident. Purpose: ● Witnesses are not allowed to talk to each other ● Prevents collusion (creating a false story together) ● Ensures in...
