Secondly, it makes clear that fraud must be "material." Necessarily courts must decide the breadth and width of "materiality." The use of the word requires that the fraudulent aspect of a document be material to a purchaser of that document or that the fraudulent act be significant to the participants in the underlying transaction. Assume, for example, that the beneficiary has a contract to deliver 1,000 barrels of salad oil. Knowing that it has delivered only 998, the beneficiary nevertheless submits an invoice showing 1,000 barrels. If two barrels in a 1,000 barrel shipment would be an insubstantial and immaterial breach of the underlying contract, the beneficiary's act, though possibly fraudulent, is not materially so and would not justify an injunction. Conversely, the knowing submission of those invoices upon delivery of only five barrels would be materially fraudulent. The courts must examine the underlying transaction when there is an allegation of material fraud, for only by examining that transaction can one determine whether a document is fraudulent or the beneficiary has committed fraud and, if so, whether the fraud was material.
Material fraud by the beneficiary occurs only when the beneficiary has no colorable right to expect honor and where there is no basis in fact to support such a right to honor. The section indorses articulations such as those stated in Intraworld Indus. v. Girard Trust Bank, 336 A.2d 316 (Pa. 1975), Roman Ceramics Corp. v. People's Nat. Bank, 714 F.2d 1207 (3d Cir. 1983), and similar decisions and embraces certain decisions under Section 5-114 that relied upon the phrase "fraud in the transaction." Some of these decisions have been summarized as follows in Ground Air Transfer v. Westate's Airlines, 899 F.2d 1269, 1272-73 (1st Cir. 1990):
We have said throughout that courts may not "normally" issue an injunction because of an important exception to the general "no injunction" rule. The exception, as we also explained in Itek, 730 F.2d at 24-25, concerns "fraud" so serious as to make it obviously pointless and unjust to permit the beneficiary to obtain the money. Where the circumstances "plainly" show that the underlying contract forbids the beneficiary to call a letter of credit, Itek, 730 F.2d at 24; where they show that the contract deprives the beneficiary of even a "colorable" right to do so, id., at 25; where the contract and circumstances reveal that the beneficiary's demand for payment has "absolutely no basis in fact," id.; see Dynamics Corp. of America, 356 F. Supp. at 999; where the beneficiary's conduct has "so vitiated the entire transaction that the legitimate purposes of the independence of the issuer's obligation would no longer be served," Itek, 730 F.2d at 25 (quoting Roman Ceramics Corp. v. Peoples National Bank, 714 F.2d 1207, 1212 n.12, 1215 (3d Cir. 1983) (quoting Intraworld Indus., 336 A.2d at 324-25)); then a court may enjoin payment.
There are at least two ways to prohibit injunctions against honor under this section after acceptance of a draft by the issuer. First is to define honor (see Section 5-102(a)(8)) in the particular letter of credit to occur upon acceptance and without regard to later payment of the acceptance. Second is explicitly to agree that the applicant has no right to an injunction after acceptance -- whether or not the acceptance constitutes honor.
