c) Avoidance of the Contract (Article 49) [304]
As a rule, the contract may be avoided only when the failure to perform amounts to a "fundamental breach of contract" under Article 25. The option provided by ULIS to the buyer to extend the date for performance and thereby to clarify whether a breach is fundamental [305] has been retained only for the case where there is no delivery at all.[305a] (Article 49(l)).[306] By analogy, the provision also applies to the failure to transfer documents of title.[307] The basis for this provision was both the general tendency to curtail the remedy of avoidance of contracts, and, above all, the fear that the procedure of extending the deadline for performance could be used to "upgrade" an unimportant violation of the contract into a fundamental breach.[308]
Further, the buyer's right to avoid the contract is also lost, according to Article 49(2), where the rule is set forth in detail, if the buyer waits too long after delivery to declare his intent to avoid.[page 78]
