Comparative Study of Khiyar al-Ghabn (Option of Deficit) in Virtual and Non-Virtual Transactions, with Emphasis on the Stipulation of Waiver: An Analysis from the Perspectives of Imami Jurisprudence and Iranian Substantive Law

Abstract

Introduction: Khiyar al-Ghabn (the option of lesion/deficit) stands as one of the most significant legal doctrines in the Iranian contractual system, playing a fundamental role in compensating for losses arising from a profound imbalance between the values of the consideration in commutative contracts. With the rapid expansion of e-commerce and virtual transactions, the question of the applicability and waiver of this option in the digital sphere has emerged as a critical challenge in contract law.

Objective: Aiming to clarify the perspectives of jurists and substantive law regarding Khiyar al-Ghabn in virtual and non-virtual transactions and to identify their points of divergence and convergence, this research conducts a comparative analysis of this legal doctrine in two different contractual contexts. Furthermore, it analyzes the role of the “stipulation of waiver” (clause of relinquishment) from the perspectives of Imami jurisprudence and Iranian substantive law.

Methodology: This study employs a descriptive-analytical method, utilizing library-based research including jurisprudential texts, legal treatises, scientific articles, and enacted laws. Data were collected through systematic note-taking from authoritative sources and analyzed using a comparative approach.

Findings: The findings indicate that despite differences in the tools and medium of contract formation, the legal nature of Khiyar al-Ghabn remains identical in both types of transactions. The stipulation to waive the option—whether express or implied—is applicable in the virtual sphere, provided that it adheres to principles of transparency, the possibility of real informed consent, and mandatory protective rules. However, in consumer-oriented electronic transactions, the seven-day right of rescission under Article 37 of the Electronic Commerce Law, as a mandatory and non-waivable right, creates a fundamental distinction from Khiyar al-Ghabn in traditional transactions. Furthermore, the waiver of all options (Khiyar), even with explicit mention of gross deficit (Ghabn-e-Fahish), shall not result in the forfeiture of the right to rescission in cases where the realized deficit exceeds customary and conventional limits.

Conclusion: Regarding the nature and conditions for its realization, Khiyar al-Ghabn in virtual transactions bears no fundamental difference from non-virtual transactions; the electronic nature of the manifestation of will pertains solely to the form of contract formation. Nevertheless, there are significant differences concerning the waiver of Khiyar al-Ghabn between these two types of transactions, primarily due to the specific characteristics of the electronic medium, such as the difficulty of establishing real awareness, delays in the realization of possession (Qabd), and the existence of the special seven-day right of rescission. The validity of the waiver of options in electronic contracts is contingent upon conditions such as real informed consent, transparency of the stipulation, the imputability of the will, and non-conflict with mandatory protective rules. Moreover, the waiver of all options shall not lead to the loss of the right to rescind in cases of gross deficit, as such cases fall beyond conventional customary limits.
