The Supreme Court today sought responses from the Centre and the National Testing Agency (NTA) on a plea seeking a CBI probe into allegations of question paper leaks and other irregularities in the NEET-UG examination. A vacation bench of justices Vikram Nath and Sandeep Mehta, which was hearing a PIL, also sought responses from the Central Bureau of Investigation (CBI) and the Bihar government within two weeks. It said the PIL will also be taken up with other pending ones on July 8. The Apex Court also issued notices to private parties on a plea of the National Testing Agency seeking the transfer of cases pending in various high courts on the NEET-UG row to the top court to avoid multiplicity of litigation.
