The Indian Constitution provides immunity to an accused against self-incrimination under Article 20(3), which states, "No person accused of an offence shall be compelled to be a witness against himself."This provision is a cornerstone of individual rights, ensuring protection against forced confessions or statements that may be used to prosecute an individual. The Supreme Court of India has played a significant role in interpreting and expanding the scope of this immunity. It has clarified that the term "witness "in this context encompasses both oral and documentary evidence, ensuring that no individual is compelled to furnish any evidence that could support prosecution against themselves.
To avail the protection under Article 20(3), the Supreme Court has established a key prerequisite: a formal accusation must exist against the individual at the time of the interrogation. This ensures that the protection applies only to those who have already been charged or are formally accused of an offense. This position was emphasized in the Selvi v. State of Karnatakacase, where the court elaborated on the meaning of a "witness."It held that a witness is someone who provides information, either orally or in writing, to assist the court or an investigation.
The landmark case of State of Bombay v. Kathi Kalu Oghadfurther defined the scope of this immunity. An eleven-judge bench of the Supreme Court ruled that while the investigative authorities are barred from compelling testimony that originates from the will of the accused, they are permitted to collect physical evidence. Physical evidence, which does not involve the volition of the accused, includes fingerprints, handwriting samples, voice samples, blood tests, and hair strands. Such evidence can be used solely for identification or corroboration of already existing evidence.
In Kathi Kalu Oghad, the court underscored the importance of distinguishing between testimonial compulsion and the collection of physical evidence. For a statement to qualify as self-incriminating, it must be shown that the accused was compelled to provide it and that it was likely to incriminate them. This judgment highlights the balance between individual rights and the needs of an investigation.
These rulings ensure that investigative processes respect constitutional safeguards while enabling authorities to collect objective evidence. By doing so, the judiciary has reinforced the sanctity of Article 20(3), maintaining a delicate equilibrium between the rights of the accused and the interests of justice. This principle safeguards personal liberty and prevents abuse of power, emphasizing the fundamental tenet that no person should be compelled to contribute to their own prosecution.

Allowing Narcotics Analysis with Consent
In the same scenario, Selvi consents to the narcotics test, claiming it might prove innocence. However, the court hesitates, fearing that allowing such tests could set a dangerous precedent, promoting measures that undermine the accused ’s autonomy over disclosing information.
