As contractual obligations and contracts is the binding nature of contracts, and the possibility of rescission of the contract is contrary to this principle and the general rule, which must be justified and proven; otherwise, even the party regretting the contract must adhere to it. Therefore, unlike rescission by mutual consent—which is a general rule consistent with the principle of the sovereignty of will—the the legislator stated in Article 219 of the Civil Code, the principle in existence of an option of rescission (Khiyar) in binding contractual obligations is an exceptional matter and contrary to the principle and must be established based on the consent of the parties or by law.
This study examines the factor that triggers this exceptional matter contrary to the principle of binding contracts and causes the dominance of the principle of rescission, granting the party the right to cancel and revoke the contract. In other words, the aim and effort of this thesis is to investigate the basis of the options of rescission (Khiyar) regarding contractual obligations.
Legal scholars have proposed several bases and justifications, two of which are fundamental and widely used:
1. Sovereignty of the will: Some legal scholars justify the options of rescission based on the principle of the sovereignty of will and explicit or implicit contractual obligations.
2.Civil liability based on the principle of "no harm": Some legal scholars justify the options of rescission based on the principle of no harm (La zarar) and compensation for the wrongful damage caused by the party having the option, using it as the foundation for these options.
Now, it remains to be seen on which basis the options of rescission included in the Iranian Civil Code are grounded. Are they all based on the first principle? or entirely on the second? or should it be considered that there is a middle ground between these bases, where some options are based on the first principle (explicit or implicit obligation or condition), others on the second, and some on none of these two?
It should also be added that the third basis, the intermediate basis, is the accepted view in this thesis.
