Understanding Scientific Investigation Techniques in Criminal Justice
Criminal investigations have seen big changes thanks to new technology. We look at how science changes how police find important evidence in big cases.
Today, police use advanced science to find the truth. They use new ways to get information that are fair and right.
Narcoanalysis Tests and Their Application
Narcoanalysis is a special way to get information. It uses drugs to make a person very calm. Then, police try to:
- Get information that might be hidden
- Check if what someone says is true
- See if someone is lying
They use sodium pentothal to help people open up. This drug helps them share things they might not want to.
Polygraph Examination Process
Polygraph tests check how a person reacts to questions. They look at:
- Changes in blood pressure
- How fast someone breathes
- Changes in heart rate
- How much sweat a person has
“Polygraph examinations provide insights into psychological responses that might indicate truthfulness or deception.” – Forensic Science Experts
Brain Electrical Activation Profile (BEAP) Testing
BEAP tests look at how the brain reacts to certain things. It helps police see if someone knows about a crime. This method checks the brain’s electrical activity to see if someone recognizes important details.
Scientific investigation techniques keep getting better. They give police better ways to find the truth while keeping people’s rights safe.
Constitutional Rights and Legal Framework
The Selvi vs State of Karnataka case explored key constitutional rights in India. It focused on Article 20(3) and Article 21. These articles protect against self-incrimination and safeguard personal freedom.
Article 20(3) is a strong defense against forced confessions in criminal probes. It stops the government from making people testify against themselves. This right keeps citizens safe from misuse of power.
- Protection against involuntary scientific tests
- Preservation of mental privacy
- Safeguarding individual autonomy during criminal investigations
Article 21 also protects personal freedom, including the right to life and dignity. It ensures people are not subjected to invasive methods that could violate their privacy and mental well-being.
The Supreme Court emphasized that constitutional rights must be preserved, even in the pursuit of criminal justice.
The right to privacy is not just about physical space. The court ruled that mental privacy and autonomy must also be respected. Forcing someone to undergo tests that could reveal incriminating information is against the law.
The Supreme Court’s decision shows the importance of balancing criminal investigations with individual rights. The court set clear rules to ensure justice and protect personal freedom.

- Potential violation of the right against self-incrimination
- Infringement of personal liberty and privacy
- Questioning the scientific reliability of investigative techniques
Arguments by Petitioners and Respondents
The debate was complex about using science in investigations. Petitioners argued that forcing people to undergo tests is wrong. They said it goes against the law.
The other side tried to say these tests are needed. But the Supreme Court looked closely at the science and law. They decided that forcing people to take these tests is against their rights.
The Court said that a person’s dignity and integrity must not be hurt during investigations.
Supreme Court’s Interpretation of Article 20(3)
The Supreme Court’s landmark case, Selvi vs State of Karnataka, changed how we see self-incrimination protection. It looked into neuroscientific methods and set up key safeguards against forcing people to testify.
Important points from the Supreme Court’s view include:
- Expanding protection beyond just words to include body responses
- Stressing the importance of giving evidence freely
- Seeing mental privacy as a basic right
The Court said that forced neuroscientific tests, like narcoanalysis and brain mapping, break constitutional rights. Testimonial compulsion now means any evidence that could harm someone without their consent.
| Test Type | Constitutional Status | Potential Rights Violation |
|---|---|---|
| Narcoanalysis | Unconstitutional | Mental Privacy Invasion |
| Brain Mapping | Unconstitutional | Self-Incrimination |
| Polygraph | Unconstitutional | Involuntary Testimony |
The Court’s detailed look at Article 20(3) made it clear that criminal investigations must respect people’s rights. By protecting against forced testimony, we keep the justice system fair and protect personal freedoms.
Impact on Personal Liberty and Privacy Rights

Protection Against Self-Incrimination
Article 20(3) of the Constitution got a new look. The Court said that forcing someone to undergo neuroscientific tests is a big deal. It’s like forcing someone to talk against themselves.
Safeguards for Test Administration
Rules were set to keep privacy safe during scientific tests:
- Everyone must agree to be tested
- Tests need a judge’s okay
- Forced tests are very limited
This focus on mental privacy makes sure investigations respect our freedom. It keeps the legal system fair and just.
