Case study
The I.C.C's opinion on this is that it is a negotiation credit and a sight credit. But the statement is not clear to decide where to apply the credit and there needs additional instruction about a opening bank. Therefore, a advising bank may request additional information to the opening bank to clarify this incomplete and unclear credit condition according to the Article 12 of U.C.P., and the opening bank must supply necessary information immediately upon request. (I.C.C pub 459. case No.29)

Case 2
A debtor opened a credit through H bank and notified the opening to a company G. The validity period for this credit was July 20th but there was no indication for document presentation date. The company G shipped the goods based on the credit, and negotiated through a bank and on the cover of the negotiation it reads that the negotiation was made on July 23rd, and on the credit documents, it was presented indicating that the shipping documents were presented within the validity period of the credit. The opening bank declares that even though the documents were presented within the validity period it is discrepancy if the negotiation occurred after the validity period so the payment was rejected for the reason.

Conclusion
According to the Article 42 of U.C.P., the available period in L/C is the final day for the payment, take over and negotiating documents to be presented. Accordingly, if a negotiating bank received documents within the available period of L/C the bank requires some time to review but even if the available period was over, it is not reasonable cause for payment rejection.
