The Validity of Forensic Evidence in India under Criminal Law

The validity of Forensic Evidence in India under Criminal Law

In the middle of the 19th-century natural science began to develop. Hence, Forensic science is the ultimate science that meets the law. It has importance inside the criminal as well as civil matters. Forensic evidence is the physical evidence that is located on the crime scene. The need for scientific evidence has increased as in other ways the research and searching can be crooked. This clearly states the clinical notion while finding the evidence in the facet of forensic science and other various technology. Hence, we can also state that the generation of forensic technology has arrived and grown at its peak to give a venture to medical science and DNA testing in the era of forensic science.

The truthful judgment is when evidence is determined on the place of crime plays a paramount role. They are generally considered secondary evidence. The number one evidence amalgamated with secondary evidence is provided in the court of law, which facilitates the courtroom to recognize the statistics and deliver the judgment.

Definition of Evidence

Strictly inside the felony context, evidence can be defined as various things provided in the courtroom to prove or disprove a query beneath inquiry. It includes testimony, documents, photographs, maps, and videotapes. These are termed as evidence of the case.

Arguments and statements by lawyers are not evidence. The lawyers are not witnesses. What they are saying of their starting statements, remaining arguments, and at other instances is intended to help you interpret the proof, however, it is not proof.
Cultivating this definition similarly brings us to your doorstep of the “Laws of Evidence”, which appreciably isn’t always a branch however altogether a different section of the legal machine.

3. Control how evidence is to be handled and considered once it is received and what conclusions, if any, are to be drawn from particular classes of evidence.
4. Specify the degree of satisfaction that the tribunal of truth need to attain in determining whether or not a fact in trouble is hooked up and the results of this kind of level of delight aren’t reached.

This is the method of numerous writers. It has been found, however, that this formulation is unsatisfactory because it includes both considerable and procedural rules. While the definition of the ‘legal guidelines of proof‘’ has been considered by using the courts, they have not attempted an exhaustive definition. After tries to define the law of evidence we could outline forensic proof and the manner it can be related to the law of evidence.

Definition of Forensic Science

Forensic technology is using technological know-how inside the provider of the regulation. Sciences utilized in forensics encompass any field that may resource in the collection, protection, and evaluation of evidence together with chemistry (for the identity of explosives), engineering (for the examination of structural design), or biology (for DNA identity or matching). A forensic scientist is a professional in any technical subject and can offer an evaluation of the evidence, witness testimony on exam effects, technical aid, and even education in his or her specialized place.

Analysis of forensic evidence is used inside the research and prosecution of civil and criminal proceedings. Often, it can assist to set up the guilt or innocence of viable suspects.

The in-depth analysis of forensic evidence brings us to the main course of our topic. The different types of methods that can be used in forensic science and their acceptability in the legal system.

The appeal highlighted the times of how those who had been accused of a crime, the suspects or witnesses involved in an investigation have been being subjected to Narco-evaluation, Brain Electrical Activation Profile (BEAP), Functional Magnetic Resonance Imaging (FMRI), and Polygraph tests without their consent.

Held: It changed into held by using the Hon’ble 3-judge bench of the Supreme Court that no individual needs to be forcibly subjected to any of the strategies in a query, whether or not within the pretext of research in crook cases or any other case.

The court docket held that these guidelines should be strictly adhered to and comparable safeguards need to be followed for accomplishing the `Narco-evaluation method’ and the `Brain Electrical Activation Profile’.

Thus, this judgment rendered the practice of Narco-analysis, brain mapping, FMRI, and polygraph test to be unconstitutional and void in the eyes of law. The judgment is one in every of its type which offers more often than not with all new aspects associated with privateness and the proper against self-incrimination covered using Article 20 (3) of the Indian Constitution.


Article 20(3) in the Constitution of India 1949 (3) No man or woman accused of any offense shall be compelled to be a witness against himself.

The Supreme Court regularly occurring that there’s a competition between societal hobby in crime detection and the constitutional rights of an accused man or woman. They admitted that the police had a difficult job to do in particular while crimes had been developing and criminals were outwitting detectives. Despite this, the protection of essential rights enshrined in our Constitution is of extreme significance, the Court stated. In the interest of protecting these rights, we cannot have the funds to put in writing off the fear of police torture leading to pressured self-incrimination. While any statement given freely and voluntarily by an accused person is admissible and even invaluable to an investigation, by the police to get information is not permitted as it violates the constitutional guarantee of fair procedure.
