In these days, there are various types of fraud in L/C transaction. But we has no article on fraud in the UCP. So the matter of fraud has been depended on the judgement of court of each country. But the judgements are different in each case. These cause the difficulties in practice. To solve this problem, it is desirable to insert the relative article in the UCP. I considered the article 5-109 of UCC for pre-study on this matter. But the article 5-109 of UCC has some problems. To arrange the relative article on fraud in the UCP, we have to consider more severely on article 5-109 of UCC. Especially, it should be studied on cases in practice. This is left for next study.
