An issuing bank must, endless supply of reports, give another repayment approval or extra guidelines unless they constitute an alteration to, or a cancelation of, a current repayment approval. On the off chance that the issuing bank does not conform to the above and a copy repayment is made, it is the duty of the issuing bank to get the arrival of the measure of the copy repayment. The repaying bank expect no risk or duty regarding any outcomes that may emerge from any such duplication.
