can a Bank deny to provide a copy of its Loan Recovery policy under RTI ACT?

I want to have a copy of Loan recovery policy document of a Bank. The Nationalised Bank, which is a government of india undertaking , is declining to provide the same on the pretext that it is a confidential document. My question is
WHETHER A NATIONALISED BANK DECLINE TO PROVIDE COPY OF THE LOAN RECOVERY POLICY OR ANY OTHER POLICY DOCUMENT TO A CITIZEN WHEN THE SAME IS SOUGHT UNDER THE R T I ACT.
