A CBI probe into the case was ordered by a single-judge bench of Justice Biswajit Basu, which also directed the central agency to submit a report in the court by April 25.

However, the state government moved a division bench of Justice Harish Tando and Justice Madhuresh Prasad against the decision, which on Friday upheld the order passed by Justice Biswajit Basu.

The division bench also directed the CBI to submit the report by April 25.

The state government had expressed suspicion over two anonymous letters alleging irregularities in the recruitment process of GTA-run schools, based on which a CBI inquiry was ordered.
