The decision was taken at a state cabinet meeting chaired by Chief Minister Yogi Adityanath.
A senior cabinet minister said, "The government will go for a CBI probe in the matter".
On July 19, the chief minister had said appointments made in the Provincial Civil Services in Uttar Pradesh by the state public service commission since 2012 would be probed by the CBI.
"What have you done to the UPPCS... Its credibility is in question. We will get all the appointments made in the UPPCS since 2012 probed by the CBI," he had said.
The chief minister had said these when he was winding up discussion in the state assembly on the annual budget for 2017-18.
