Questions and answers on law (Part 90)

Q 1:-  A person has died by strangulation and a rope is found, how would this rope would be connected to the accused. How would Judge appreciate the evidence? What would be material evidence to this regard? 

Ans:- In such a case, the rope by itself is not enough; it must be linked to the accused through a complete chain of medical, forensic, recovery, and circumstantial evidence. The court should see whether the rope is proved to be the likely ligature used, whether it is connected with the accused, and whether all circumstances together exclude innocence.

30-second answer

In a strangulation case, mere finding of a rope is not sufficient. The prosecution must connect the rope to the crime and then to the accused through medical opinion, forensic examination, lawful seizure, and surrounding circumstances. I would appreciate the evidence by seeing whether the post-mortem shows ligature strangulation, whether the ligature mark matches the rope, whether the rope was recovered from the accused or at his instance, whether FSL shows blood, hair, skin, fingerprints, or fibre transfer, and whether this is supported by motive, last seen, conduct, and recovery evidence. Conviction can rest only when the entire chain is complete.”

Material evidence

  • Post-mortem evidence proving homicidal death by strangulation, including nature and position of ligature mark.

  • The rope itself, properly seized, sealed, and identified in court.

  • FSL evidence, such as fibre comparison, bloodstains, skin tissue, hair, DNA, fingerprints, or a physical match with rope source.

  • Recovery evidence under Section 27 of the Evidence Act, if the rope or related article is discovered at the accused’s instance.

  • Circumstantial evidence like last seen, motive, injuries suggesting struggle, false explanation, abscondence, or concealment.

How to appreciate

The court should first distinguish homicide from suicide or accidental hanging by reading the medical and scene evidence together, because both may involve a ligature around the neck. Then it must test whether the rope is merely a suspicious article or whether it is scientifically and legally connected to the accused through a reliable chain of custody and corroborative circumstances.

Q 2:- What is evidentiary value of sniffer dog?

Ans:- Sniffer dog evidence has only limited evidentiary value: it may aid investigation, but by itself it is not substantive proof of guilt and cannot be the sole basis of conviction.

30-second answer

Evidence of a sniffer dog is only corroborative and not substantive. It can help the police during investigation in tracing the accused or objects, but the dog’s reaction by itself is weak evidence because it is interpreted through the handler, cannot be tested by cross-examining the dog, and is prone to error. Therefore, courts treat it with great caution, and conviction cannot rest solely on sniffer dog evidence.”

Short points

  • Useful at the investigation stage for tracing suspects or articles.

  • Its probative value is weak and limited.

  • It generally needs independent corroboration from other evidence.

  • Courts are cautious because of possible error by the dog or wrong interpretation by the handler.

Case line

The settled position reflected in legal commentary on Supreme Court case law is that sniffer dog services may be used for investigation, but their faculties cannot be relied on to establish guilt.
