The complaint against him is for misuse of official position and criminal misconduct when he was chief minister in 1989.

'Virbhadra Singh and his wife Pratibha Singh were booked Monday night by the state vigilance and anti-corruption bureau under the Prevention of Corruption Act, 1988. They were booked under sections related to misuse of official position and criminal misconduct,' Inspector General of Police (Vigilance) S.R. Mardi said.

He said they were booked on the basis of an audio CD released by Vijai Singh Mankotia, a political rival of the Congress leader, in 2007. In the CD, Virbhadra Singh was heard referring to some monetary transactions on phone with former IAS officer Mahinder Lal, who is now dead. The CD also contained recordings of his wife, a former MP from the state's Mandi constituency.
