ABSTRACT
The question of using the body of the accused as an investigatory tool under Article 20(3) of the Indian Constitution is indeed a tricky one. The use of fingerprint evidence, handwriting and voice samples has, in general, not been seen as a means of compelling testimony, but the constitutional status of crime-scene re-enactment remains less settled. Recently, in State of Tamil Nadu v. Ponnusamy, the Supreme Court held that re-enactment is not per se testimonial compulsion. The Court has made a distinction between a demonstration which involves walking or imitating a visual sequence (a directed physical demonstration) and a demonstration which requires the accused to give incriminating disclosure on the basis of personal knowledge. This article contends that although the distinction is constitutionally defensible, its application is not always clear. The difficulty is that bodily conduct can serve both as evidence of a physical characteristic and as a vehicle for communicating personal knowledge. The article suggests a method for determining the constitutional nature of re-enactment based on an “information-content” approach, in which the nature of re-enactment depends on the type of information sought, its source (and thus, the purpose for which the compelled act is performed), and the evidentiary chain subsequently derived from it. This approach would permit legitimate forensic investigation while reducing the possibility that the constitutional prohibition on testimonial compulsion could be circumvented merely by changing the form of communication.

- INTRODUCTION
Suppose a person is suspected of committing a theft and is asked to walk 10 metres and describe his walk. They then ask him to walk in a similar manner to the one observed in the CCTV footage. Finally, they demand that he show how he allegedly attacked his victim and then got out of the room. All three involve the accused’s body, but it would be difficult to maintain that they raise the same constitutional issue. The first merely provides a physical attribute that can be compared. The second can help in identification. The third, however, may require the accused to recreate an event on the basis of personal knowledge of the alleged crime. The distinction is very significant because Article 20(3) does not just seek to prevent the accused from being forced to speak, but also to prevent the accused from being ‘compelled to be a witness against himself.’
Indian law has traditionally distinguished testimonial evidence from physical or material evidence. This distinction was elaborated on by the Supreme Court in Selvi v State of Karnataka[1] in the context of ‘narcology’, polygraph tests, and brain electrical activation profile tests which are not merely physical. This distinction was later used in State of Bombay v Kathi Kalu Oghad[2] to conclude that fingerprints and palm and foot prints are distinguishable from information communicating personal knowledge.
These principles come face-to-face with crime scene re-enactment in the recent decision of State of Tamil Nadu v Ponnusamy[3]. The Supreme Court stated that it is not enough for the accused to be involved in re-enactment for it to be declared unconstitutional. This article suggests that Ponnusamy has taken the right starting point in adopting this decision, but has left an important boundary issue unaddressed i.e. when does a bodily performance become a conveyance of incriminating personal knowledge rather than just physical evidence? The problem is that the physical/testimonial distinction takes for granted that physical evidence and communication are separable, in a more-or-less easy way. Re-enactment is a challenge to this assumption. The body can be the subject of post mortem examination and the means of conveying information.
This article therefore proposes an information-content approach. Rather than simply posing the question of whether an act is physical, a court may ask itself what information the State is trying to obtain, whether that information comes from a physical characteristic or from personal knowledge, the reason the accused is being compelled to do the act and what information is then provided in the act.
