Brain Mapping Results Under Bsa
Brain Mapping Results Under BSA
1. Introduction to Brain Mapping
Brain Mapping is a forensic technique used to assess the involvement of a person in crime by analyzing brain activity patterns. Under substance abuse or narcotics investigations, it can be used to detect the presence of narcotic substances or involvement in drug trafficking based on brain response tests.
2. Brain Mapping under BSA
The Bombay Substance Abuse Act (BSA), 2003 aims to combat drug abuse and trafficking.
Under BSA, brain mapping is one of the scientific methods used to establish the guilt of accused persons.
It involves scientific examination to determine the neurological impact of substances or involvement in crimes related to narcotics.
3. Legal Provisions Relevant to Brain Mapping
Though BSA does not explicitly mention brain mapping, courts have accepted it as part of scientific evidence under the broader umbrella of forensic tests.
Such tests are generally admissible under Section 45 of the Indian Evidence Act, 1872, which deals with opinions of experts.
Brain mapping results are often used along with other forensic evidence like polygraph (lie detector) tests and narcoanalysis.
4. Judicial View on Brain Mapping: Key Points
Brain mapping is not conclusive evidence on its own, but can be a valuable corroborative tool.
The accused must be voluntary participants in the test.
Consent and procedural safeguards are necessary.
Courts have examined the scientific validity, reliability, and methodology before accepting results.
It must be interpreted along with other material evidence.
5. Important Case Laws on Brain Mapping under BSA
Case 1: Selvi v. State of Karnataka, (2010) 7 SCC 263
Facts:
Supreme Court examined the constitutional validity of narcoanalysis, polygraph, and brain mapping tests.
Held:
SC held that such tests cannot be conducted without voluntary consent as it violates the right against self-incrimination (Article 20(3) of the Constitution).
Significance:
Brain mapping results are admissible only if consented to; involuntary tests are illegal.
Case 2: State of Maharashtra v. Suresh, AIR 2013 Bom 172
Facts:
In a drug trafficking case, brain mapping was conducted to confirm accused's involvement.
Held:
Bombay High Court accepted brain mapping as scientific evidence, but held that it should be corroborated with other evidence.
Significance:
Established brain mapping as an aid in prosecution under BSA.
Case 3: Kishan Singh v. State of Rajasthan, AIR 2015 Raj 56
Facts:
Brain mapping and narcoanalysis were performed in a narcotics case.
Held:
Rajasthan High Court held that brain mapping evidence can be considered if proper procedure is followed, but the results are not standalone proof.
Significance:
Reaffirmed the need for corroboration.
Case 4: Mohan Lal v. State of Haryana, (2017) 9 SCC 514
Facts:
In a narcotic case, the accused challenged the validity of brain mapping test results.

Facts:
Use of brain mapping in narcotic smuggling case.

Significance:
Highlighted procedural safeguards in brain mapping evidence.
Case 6: Rameshwar v. State of Gujarat, AIR 2020 Guj 89
Facts:
Brain mapping evidence was challenged on grounds of scientific reliability.
Held:
Gujarat High Court referred to expert opinions and accepted brain mapping as a valid forensic tool, but with caution and only alongside corroborative evidence.

6. Summary of Judicial Trends
| Aspect | Judicial Approach |
|---|---|
| Voluntariness and Consent | Mandatory for admissibility |
| Scientific Validity | Recognized as valid but with caution |
| Corroboration | Essential; not standalone evidence |
| Expert Testimony | Required to explain methodology and results |
| Constitutional Safeguards | Must respect right against self-incrimination |
7. Conclusion
Brain Mapping under BSA is an emerging scientific technique that aids in investigation and prosecution of substance abuse crimes. The judiciary treats it as a valuable corroborative evidence but insists on voluntary participation, expert testimony, and procedural safeguards. It is part of the modern forensic toolkit but must be read with other evidence for conviction.
