A Division Bench comprising Justices M M Sundaresh and M Sundar directed the DVAC to file the status report on a public interest litigation.
The PIL was filed by RTI activist G Balaji seeking a CBI probe into the alleged irregularities of Rs 1,000 crore in purchase of bitumen for road-laying and maintenance works.
Bitumen, a major road construction constituent, has become a primary source for officials of the state highways department to siphon off public funds, Balaji has alleged in his petition.
Submitting some documents, which he claimed, were proof he gathered through RTI applications from the department, the petitioner wanted the court to order a probe by the CBI or any other independent agency.
