In a significant development concerning the ongoing investigation into the 2026 NEET-UG paper leak scandal, three key accused individuals have formally petitioned a designated fast-track court in Delhi, volunteering to undergo advanced scientific interrogations.
On Tuesday, August 4, 2026, the accused—identified as Mangal Lal Biwal, Dinesh Biwal, and Vikas Biwal—moved an application seeking the court’s permission to be subjected to a polygraph (lie-detector) test as well as a Brain Electrical Activation Profile (BEAP) examination, commonly known as brain mapping.
The plea submitted by the trio explicitly states that their request to undergo these tests is being made “voluntarily, without any coercion”. The accused argue that participating in these scientific examinations will help “demonstrate their bona fides” and assist the Central Bureau of Investigation (CBI) in conducting a “fair and transparent investigation”.
According to the application, the primary motivation is to help the investigating agency find the real perpetrators by offering themselves for recognized scientific evaluation, ensuring that “every lawful investigative avenue capable of aiding the search for truth may be explored”.
The applicants also specified that they are willing to have the tests conducted at any government-approved Forensic Science Laboratory (FSL). They emphasized that the procedures would be carried out strictly in accordance with the law and would remain subject to all necessary constitutional and procedural safeguards. This move represents a proactive defense strategy by the accused to establish their innocence in a case that has triggered nationwide outrage and massive student protests.
The designated special court has responded by seeking an official reply from the CBI regarding the maintainability of this plea. The matter has been scheduled for a crucial hearing on August 6, where it will be taken up alongside the main chargesheet and the pending bail applications of the accused.
Interestingly, Tuesday’s proceedings also coincided with an administrative shift within the judiciary handling this high-profile case. Special Judge Ajay Gupta officially took charge as the newly designated judge dealing with the NEET paper leak matters. He replaced Special Judge Anu Grover Baliga, who was recently transferred to a special National Investigation Agency (NIA) court to adjudicate terror-related cases, following a Delhi High Court notification issued on August 1.
Judge Baliga had only recently been appointed to the role on July 23, after the high court established a “designated court to deal with criminal cases arising from paper leaks as well as the use of other unfair means in public examinations”.
The swift establishment of these fast-track courts aligns with Prime Minister Narendra Modi’s recent announcements promising rapid judicial action to address the systemic issue of paper leaks that have compromised the integrity of India’s examination system. The CBI’s forthcoming response to the lie-detector request will likely set the tone for the next phase of this complex investigation.
