AFTER the judiciary, it appears to be the turn of the countrys Central bank to turn activist. Recently, the Reserve Bank of India (RBI) virtually rejected the statutory ruling of the Company Law Board in the Tamilnad Mercantile Bank case. The Tuticorin-based bank hit the headlines a couple of years ago when the Ruias of the Essar Group acquired the majority shares of this bank from the family of one of the original promoters. The Ruia brothers had earlier won a legal battle after picking up the equity at a hefty price of Rs 4,750 per Rs 10 share.
