Justice R Subbaiah before whom the writ petition filed by one S P Sreenivas came up for hearing, directed CBI to file its response within two weeks.
The petitioner alleged that the former minister had abused his position in power purchase deals and with the help of the state-run TANGEDCO officials, caused a loss of around Rs 25,000 crore.
However, DVAC 'colluded' with the accused and it was "attempting to close the file" and hence he moved the court for a direction to CBI to probe the matter.
The petitioner alleged that to favour solar power generators, the former minister had allowed power purchase at the rate of Rs 7.01 per unit instead of Rs 5.01. He claimed that adjacent states purchased power at Rs.5.01 per unit.
Hence, the tarrif order of TNERC should have been challenged by the state-run TANGEDCO, he contended.
The judge also said the present petition be clubbed with the criminal original petition already pending before the high court after taking permission from the Chief Justice.
