In his complaint filed on March 30, Inder Prajapat, a former general secretary of state unit, has sought criminal prosecution of Singh while alleging concealment of evidence, blackmailing and harbouring offenders in the case.
The Chief Judicial Magistrate (CJM) has fixed April 30 for recording Prajapat's statement.
He alleged that Singh was blackmailing people claiming that he had original excel sheets recovered from the computers of former MPPEB system analyst Nitin Mahindra.
The complaint also alleged that Singh was not revealing the entire contents of excel sheets which he claimed he possesses, to fuel speculation and confusion, and to blackmail people.

It also said that not disclosing evidence is a crime and Singh should either submit it to the court or to the Special Task Force (STF) probing the MPPEB scam.
Top Congress leadership, including Singh, former Union ministers Kamal Nath and Jyotiraditya Scindia, had earlier launched a strident attack against Chief Minister Shivraj Singh Chouhan in connection with the scam alleging the original excel sheet was "fudged" to "strike out" his name.
According to Congress leaders, including Singh, the original excel sheet was tampered with to "shield" Chouhan and his family.
Prajapat was expelled from Congress after he allegedly shot and injured his colleague Manak Agrawal in July 2001, during Digvijay Singh-led Congress government in Madhya Pradesh. He was reinducted in 2009.
