Background and Purpose: The authority of Cairo and its effect on the contract is one of the common defenses in arbitration courts. There is no doubt that determining the limits and loopholes of this concept can greatly help to create balance and security in economic relations. In recent years, the efforts of private law drafting institutions such as the Private Law Unity Institute and UNCITRAL have had a significant impact on clarifying the effect of these principles on international contracts.
