Legal Bases for the Interpretation of Contract Terms under the UNIDROIT Principles of International Commercial Contracts

Purpose – This paper examines the legal standards for the interpretation of contract terms in the UNIDROIT Principles of International Commercial Contracts (PICC) and the cases thereunder in order to provide academic implication to promoting an appropriate understanding of this topic in practical business. Design/methodology – This article uses the literature research and case study under the PICC. Findings – the contract terms shall be interpreted according to the common intention of the parties. If such an intention cannot be established, the contract shall be interpreted according to the meaning that reasonable persons of the same kind as the parties would give to it in the same circumstances. The statements and other conduct of a party shall be interpreted according to that party’s intention if the other party knew or could not have been unaware of that intention. If not, the reasonable person standard will apply. In applying above articles, all relevant circumstances including the conduct of the parties, practices and usages shall be considered. Terms and expressions shall be interpreted in the light of the whole contract or statement in which they appear and contract terms shall be interpreted so as to give effect to all the terms rather than to deprive some of them of effect. Where contract terms supplied by one party are unclear, contra proferentem rule applies. Where there is discrepancy between several equally authoritative versions of a contract, a preference is given to the interpretation according to the version originally drawn up. Where the parties to a contract have not agreed regarding an important term for their rights and duties, a term which is appropriate in the circumstances shall be supplied. Originality/value – This article examines various cases regarding the topic that were determined under the PICC. By finding legal standards and rulings of relevant cases, this article will help readers in practical business to enhance the ability to apply the provisions to their contracts.
