Delay in Getting Pension arrears by VRS Bank staff

Many Banks have not yet paid pension arrears to VRS bank staff who had put up less than 33 years service at the time of taking VRS. Some banks have promptly paid the arrears as per Supreme Court judgement i.e adding 5 years service wherever applicable for calculating pension.Why such delay of more than 3-4 months by some banks?
