In 2009, the Bharatiya Janata Party government was in power in the state.
Another petition, again filed by Katwal, is pending in the high court in which he alleged that despite the state vigilance bureau registering a first information report in 2006 on the directions of the high court, no investigation was being carried out into the illegal recruitments between 1993 and 1998.
During this period, Virbhadra Singh was at the helm.
But the chief minister has also sued Bharatiya Janata Pary leader Arun Jaitley, former chief minister Prem Kumar Dhumal and his sons, BJP MP Anurag Thakur and Arun Dhumal.
In the three defamation suits filed in a Shimla court in January, Virbhadra Singh said Jaitley and the Dhumals unleashed a malicious campaign against him and his family through the media.
