Impossibility of Performance of Contract in the United Nations Convention on Contracts for the International Sale of Goods

The Impossibility of performance of the contract as an exemption from liability, arising from the breach of contract, is an issue which is discussed in the sale contracts. International Sale of Goods which is enacted in ۱۹۸۰, discusses the matter in its Article ۷۹. The CISG abstains to use such terms as Frustration and Force majeure which are used in national legal systems. This prevention of using such terms thought to be the way that CISG keeps itself independence from national legal systems. As a result the CISG ordains its specific terms and conditions to set up the exemption for damages arising from the breach of contract by the person who has faced impediments and breached the contract. This research studies different aspects of the impossibility of performance of contract in The Convention on the International Sale of Goods, therefore not only it presents the concept and bases of occurrence of the Force majeure, it discusses applicable examples such as sanctions and changes in regulations as Force majeure.
