The CBI has filed a nearly 20,000-page chargesheet against 13 accused, citing 360 witnesses, 422 documents, and 43 material objects.

The Delhi court's decision to reject the plea for polygraph and brain-mapping tests in the NEET paper leak case has sparked interest in the admissibility of such evidence in Indian courts. The accused, Mangal Lal Biwal, Vikas Biwal, and Dinesh Biwal, had sought permission to undergo these tests voluntarily, claiming it would help demonstrate their innocence and assist the CBI investigation. However, the court's rejection raises questions about the reliability and validity of polygraph and brain-mapping tests in proving guilt or innocence. The CBI has filed a nearly 20,000-page chargesheet against 13 accused, citing 360 witnesses, 422 documents, and 43 material objects. The case originated from a complaint lodged by the Department of Higher Education on May 12, concerning alleged irregularities in the NEET-UG 2026 examination held on May 3.

The accused had argued that a fair investigation and trial were facets of their fundamental rights under Article 21 of the Constitution. However, the court's decision to reject the plea for polygraph and brain-mapping tests suggests that these tests may not be considered admissible evidence in Indian courts. The CBI opposed the plea, with Senior Public Prosecutor V.K. Pathak submitting that the application was not maintainable and seeking costs against the accused. This raises questions about the role of polygraph and brain-mapping tests in high-profile investigations like the NEET paper leak case.

The court's decision may set a precedent for other jurisdictions and could impact the admissibility of such evidence in Indian courts. Lawyers should watch for the potential implications of this decision on future cases involving polygraph or brain-mapping tests, particularly in high-profile investigations like the NEET paper leak case. The CBI has been conducting an extensive investigation into the alleged irregularities and leakage of the NEET-UG 2026 question paper, with searches conducted at 92 locations across multiple states. The court took cognisance of the chargesheet on August 12.

Lawyers should watch for the potential implications of this decision on future cases involving polygraph or brain-mapping tests, particularly in high-profile investigations like the NEET paper leak case. The court's ruling may set a precedent for other jurisdictions and could impact the admissibility of such evidence in Indian courts.
