This paper addresses the principles of hardship and specific performance as being unreasonably burdensome or expensive both in terms of their definitions and legal consequences. This paper argues that, in a situation of hardship, the debtor can choose to invoke either the rules of section 6.2 (hardship) or the defense to specific performance under Article 7.2.2-b of the UNIDROIT Principles of International Commercial Contracts (“UNIDROIT Principles”). Yet, while in a situation where performance of the contract becomes “unreasonably burdensome or expensive,” the debtor might only invoke the exception to specific performance under Article 7.2.2(b) of the UNIDROIT Principles.
