Polygraph & Narco analysis test

Polygraph Test:

It is based on the physiological responses given by the accused and is used to assess if a person is lying or not.

These physiological responses include variations in blood pressure, pulse rate, respiration, change in sweat glands activity, blood flow, etc.

They are captured through instruments like cardio cuffs or sensitive electrodes that are attached to the person.

A numerical value is assigned to each response to conclude if a person is telling the truth or deceiving or uncertain.

Narco Analysis:

Narco analysis test involves injection of a drug called ‘sodium pentothal’ that induces a hypnotic or sedated state in the accused that neutralizes their imagination.

It is expected to make them divulge information that is true.

The drug is also referred to as truth serum and is used in large doses as anaesthesia during surgery.

Legal implications:

In Selvi vs State of Kerala, Supreme Court ruled that no lie Detector test should be administered except on the consent of the accused.

Forcing an individual to these tests amounts to unwarranted intrusion into personal liberty.

Court also examined the scope of article 20(3), the right against self-incrimination that states that no accused can be compelled to be a witness against himself.

Scope of investigating agencies:

The law enforcing authorities need to abide by the guidelines issued by the National Human Rights Commission for administering polygraph tests on an accused.

The results of the test cannot be considered as confessions as a person in a drug induced state cannot exercise choice in answering questions.

But the information or material subsequently discovered during such a process can be admitted as evidence in the court.

These provisions are in line with the International norms on human rights, the right to fair trial and the right against self-incrimination under article 20 of the constitution.

The returning officer would deploy polling teams, which will deliver and collect the postal ballot on pre-informed dates and then deposit it with the returning officer.

The form required to opt for the postal ballot would be delivered at the residence of all those aged above 80 and people with disabilities by the booth level officer under his polling station.

What is postal voting?

A restricted set of voters can exercise postal voting. Through this facility, a voter can cast her vote remotely by recording her preference on the ballot paper and sending it back to the election officer before counting.

Who else can avail this facility?

Members of the armed forces like the Army, Navy and Air Force, members of the armed police force of a state (serving outside the state), government employees posted outside India and their spouses are entitled to vote only by post.

The exception to the above-mentioned category of voters is provided under Section 60 of the Representation of the People Act, 1951.

What is a narco test?

In News:

Uttar Pradesh government is planning to subject the Hathras rape and murder victim’s family members to narco tests.

What are the concerns?

The consequences of such tests on “individuals from weaker sections of society who are unaware of their fundamental rights and unable to afford legal advice” can be devastating.

It may involve future abuse, harassment and surveillance, even leakage of the video material to the Press for a “trial by media.”

Such tests are an affront to human dignity and liberty, and have long-lasting effects.

What are narco test?

Narco test involves the injection of a drug, sodium pentothal, which induces a hypnotic or sedated state in which the subject’s imagination is neutralised, and they are expected to divulge true information.

The drug, referred to as “truth serum” in this context, was used in larger doses as anaesthesia during surgery, and is said to have been used during World War II for intelligence operations.

How is it different from Polygraph test?

A polygraph test is based on the assumption that physiological responses that are triggered when a person is lying are different from what they would be otherwise.

Instruments like cardio-cuffs or sensitive electrodes are attached to the person, and variables such as blood pressure, pulse, respiration, change in sweat gland activity, blood flow, etc., are measured as questions are put to them.

A numerical value is assigned to each response to conclude whether the person is telling the truth, is deceiving, or is uncertain.

Are Indian investigators allowed to put suspects through these tests?

In Selvi & Ors vs State of Karnataka & Anr (2010), a Supreme Court ruled that no lie detector tests should be administered “except on the basis of consent of the accused”.

It also said the ‘Guidelines for the Administration of Polygraph Test on an Accused’ published by the National Human Rights Commission in 2000, must be strictly followed.

The court took into consideration international norms on human rights, the right to a fair trial, and the right against self-incrimination under Article 20(3) of the Constitution.
