"Article 37 of the CISG corresponds essentially to Article 37 ULIS. However, a second sentence was added, which provides that the buyer retains his right to claim damages even where defects have been successfully cured." Schwenzer in Commentary on the UN Convention on the International Sale of Goods, Peter Schlechtriem ed. (Oxford 1998) 295 [citations omitted].
