Subhiksha managing director R Subramanian in a statement, said Kotak Mahindra Bank filed an objection to the merger in the Madras High Court.
The company had earlier filed various documents as directed by the HC. The HC has adjourned the hearing to April 28, he added.
In June 2008, Subhiksha planned to acquire 23 per cent stake in Blue Green Constructions for Rs 2.5 crore (Rs 25 million). But ICICI Venture, promoted by Azim Premji, which has 10 per cent stake in Subhiksha, objected to the move.
