B. Types Of Forensic Evidence

1. Biological Evidence: This includes samples such as blood, saliva, hair, and other bodily fluids or tissues. DNA analysis, a significant technique in this category, is used to identify individuals and establish genetic relationships.
2. Physical Evidence: Physical evidence includes items such as weapons, clothing, fingerprints, footwear impressions, and tire marks. Techniques like fingerprint analysis, ballistics, and tool mark analysis fall under this category.
3. Trace Evidence: This consists of small but significant pieces of evidence, often microscopic, such as fibres, hair, glass, or paint. Analysing trace evidence helps link suspects, victims, and crime scenes.
4. Digital Evidence: In the digital age, this category encompasses data from electronic devices like computers, smartphones, or online platforms. Digital forensics involves the recovery and analysis of digital evidence to uncover cybercrimes or related activities.

C. Forensic Techniques And Technologies

Forensic science employs an array of specialized techniques and technologies, including but not limited to:

1. DNA Analysis: Polymerase Chain Reaction (PCR) and Short Tandem Repeat (STR) analysis for identifying individuals and establishing genetic profiles.
2. Fingerprint Analysis: Employed to match fingerprints found at crime scenes to those in databases, aiding in suspect identification.
3. Ballistics: Utilized to link firearms to specific cases through the analysis of bullets, cartridge casings, and gunshot residue.
4. Forensic Toxicology: Analysis of bodily fluids to detect drugs, alcohol, or poisons, often crucial in cases of suspicious deaths or drug-related crimes.

D. Legal Framework For The Use Of Forensic Evidence In India

Forensic evidence holds immense significance in the Indian criminal justice system, guiding investigations and judicial proceedings. The legal framework governing its utilization is delineated through various statutes that provide guidelines for its collection, preservation, admissibility, and presentation in courts.

1. The Code of Criminal Procedure (CrPC)

The Code of Criminal Procedure (CrPC) forms the bedrock of procedural laws governing criminal investigations and trials in India7. Specifically, Sections 53 and 54 of the CrPC pertain to the examination of accused persons. Section 53 grants the authority to conduct medical examinations of the accused, including forensic assessments7. This enables law enforcement to obtain critical forensic evidence from the accused, such as bodily fluids or samples, for further analysis.

Moreover, Section 293 of the CrPC is pivotal in establishing the admissibility of forensic reports in court7. Forensic reports, such as those relating to autopsies or chemical analyses, are considered as primary evidence when they are signed by the authorized personnel and comply with the legal requirements specified in this section7.

2. Indian Evidence Act, 1872

The Indian Evidence Act, 1872, governs the rules related to the admissibility of evidence in India, including forensic evidence. Section 45 of the Act deems the opinion of experts, including forensic experts, as relevant in certain circumstances8. This provision enables experts to present their opinions on matters such as handwriting analysis, fingerprint matching, or DNA profiling, establishing the authenticity and relevance of forensic evidence. Additionally, Section 293 of the CrPC complements the Indian Evidence Act by providing the legal basis for the admissibility of forensic reports in court, ensuring that such reports are admissible as evidence when prepared and submitted following prescribed legal procedures9.

3. Information Technology Act, 2000

The Information Technology Act, 2000, and its subsequent amendments encompass provisions relating to the admissibility and legal aspects of digital evidence10. In the contemporary era, digital evidence is of paramount importance, especially in cases involving cybercrimes, data theft, or electronic transactions. The Act offers a legal framework for the collection and use of digital evidence, ensuring that it is admissible in courts and can be utilized effectively in investigations and legal proceedings10. It establishes legal norms to handle digital evidence securely, protecting its integrity and authenticity.
