NEET Paper Leak Case Takes New Turn As Accused Demand Lie Detector Tests

The first fast track court hearing saw accused seek polygraph, brain mapping and lie detector tests, while CBI must respond on August 6

After nationwide protests over paper leaks, Prime Minister Narendra Modi announced fast track courts. The move aimed to ensure strict punishment for those harming students’ futures.  For this purpose, four High Courts received responsibility. These included Bombay, Calcutta, Delhi and Madhya Pradesh High Courts. The first hearing in the NEET paper leak case was scheduled for July 27. However, the hearing did not happen because CBI officials did not appear. Therefore, the court postponed the initial proceedings. Meanwhile, judge Anu Grover Baliga was transferred from the fast track court.

Later, judge Ajay Gupta received charge of the fast track court. He announced daily hearings for this student-related case.

Accused demand polygraph and brain mapping tests

The first hearing finally took place on August 4. During proceedings, accused presented a new demand before the court. The accused requested polygraph tests, brain mapping tests and lie detector examinations. Their lawyer AP Singh submitted the application. Following this, the fast track court issued a notice to CBI. The court asked the agency to respond regarding the request.

The court also questioned the legal validity of this application. However, accused can seek such tests to prove innocence or change investigation direction. According to legal experts, accused are attempting to establish innocence. They also want to challenge CBI’s claims through this request.

Now, CBI must inform the court on August 6. The agency has to clarify whether it agrees to the polygraph test.

Court asks CBI to complete charge sheet process

The fast track court directed CBI to complete charge sheet examination by Wednesday evening. The agency must provide copies to all accused by August 6. The court still needs to examine the charge sheet. Meanwhile, hearings on bail pleas of Dinesh Bival and Vikas Bival moved to August 6. Their lawyer AP Singh had requested charge sheet copies. The court had earlier raised concerns about missing documents, statements and materials. CBI informed the court that the charge sheet and documents contain around 20,000 pages. The scanning process requires additional time.

The agency needs to provide documents to 13 accused. Judge Anu Grover Baliga earlier allowed three days.

However, the deadline shifted from August 3 to August 6. CBI already filed a 20,000-page charge sheet against 13 accused.

The document mentions 360 witnesses, 422 documents and 43 physical items. Currently, all 13 accused remain in jail.

CBI investigation expands across multiple states

CBI registered the FIR on May 12, 2026. The agency formed multiple teams with 72 officers and eight cyber forensic experts. Furthermore, investigators conducted searches at 92 locations. These searches covered Maharashtra, Rajasthan, Haryana, Delhi and other states.

The first arrest occurred on May 13. Overall, authorities arrested 13 accused in this case.

The arrested individuals include three NTA subject experts from chemistry, biology and physics. CBI also froze several bank accounts, lockers and one Demat account.

What is a lie detector test?

A lie detector test checks whether a person speaks truth or lies. However, the machine does not directly identify false statements. Instead, it measures psychological changes during deception. When someone intentionally lies, stress and fear activate the sympathetic nervous system. As a result, body functions can change. During testing, officials attach sensitive sensors and equipment to the person.

However, experts continue debating its accuracy. The test does not provide 100 percent certainty.
