The Reserve Bank of India today relaxed cheque-book norms leaving it to the lender's discretion on whether to issue fresh cheque-books or not in cases of dishonour of 1 crore rupees and above.RBI said in a notification issued today that banks should put in place an appropriate policy approved by the board or its committee taking into consideration the need to prevent misuse of cheque drawing facility and avoid penalising customers for unintended dishonour of cheques.The bank regulator also asked the banks to make the policy transparent and bring it to the knowledge of the customers. As per the existing directive, banks are not allowed to issue fresh cheque books in the event of cheque dishonour valuing 1 crore rupees and above on four occasions during a financial year for want of sufficient funds.Also, in such cases the bank may consider closing the current account at its discretion. RBI said it has reviewed these instructions and it will be now up to the discretion of banks how to respond in such cases.
