The tribunal has posted the matter for more hearing to December 16.
The company said an investigation instituted by its board had found major governance and financial lapses, including some assets being provided as collateral and the money from the loans siphoned off by "identified company personnel, both current and past, including certain non- executive directors."
His removal as chairman was so dramatic that the circular decision of the board was conveyed to Thapar in an email at 0300 hrs on August 30.
The company later appointed Ashish Kumar Guha as the new non-executive chairman.
Following the promoters sacking, the board had on October 18 moved market regulator Sebi seeking to reclassify Thapar's Avantha Holdings and others from promoter shareholders to public shareholders. The application is pending with the Sebi.
Reclassification of Avantha will be easier after its shareholding in CG Power fell to less than 1 percent after lenders invoked pledges on shares pledged for taking loans.
Thapar-led promoter group had held 21.54 crore shares, constituting 34.38 per cent stake, as on April 1, 2018, according to the annual report for FY19. Almost all of these shares were pledged by the promoters to their lenders, it said, adding as of now Thapar holds just about 8,574 shares, or 0.001 percent of total share capital of company.
